Top 5 Misconceptions About Blockchain

When we are faced with a new technology, we often look for analogies to understand and describe it. To bridge the knowledge gap, we seek analogies from the universe concepts familiar to us.
In our search for the right analogies, we often risk misunderstanding this new technology. Blockchain technology has introduced a paradigm shift in the way we organize ourselves to generate, account for, transfer and store value. Yet, we are still in early stages of understanding its importance.
In this post I will try to shed light on the top 5 major misconceptions about digital assets and about the open blockchain—a technology that underlies them.
1. Blockchain, not bitcoin
This misconception stems from failing to realize why blockchain exists in the first place. In essence, blockchain is a shared ledger designed to function in an extremely hostile, open environment. It derives its value from the security of its tamper-proof records.
In the blockchain networks powered by proof-of-work (PoW) algorithms, that security is achieved by miners competing to solve a computationally intensive puzzle. The miners do this with the expectation of receiving a digital token as a reward. This digital token can be freely redeemed for fiat currency to cover their operating costs and generate profits. These open systems are designed in such a way that value of their token ultimately dictates the level of security of their network.
When we decouple the concept of blockchain from its underlying token, it simply wipes out most, if not the entire, value proposition the blockchain as a concept.
Implementing blockchain as a token-less system of recordkeeping within a single company is perhaps the prime example of this misconception. Such an endeavor fails to use one of the most valuable properties of the open blockchain. Implementing a blockchain solution in such settings may even be counter-productive especially when better alternatives exist, in the form of databases with proper access control.
Blockchain could be useful in a commercial setting where a consortium of companies decides to use a single ledger to keep track of important transactions. An example of such transactions could be shares of companies that are traded on Wall Street millions of times each day. These transactions are reconciled periodically between the financial institutions by a trusted third-party entity, which could be ultimately replaced by a blockchain-based protocol at a fraction of their cost. That said, these systems may never become as secure and tamper-proof as the open blockchain as the security of the network depends on the number of its minestaking nodes.
2. Exchange Hacks = Digital Assets Are Not Secure
Centralized digital asset exchanges are popular avenues for exchanging digital assets for currencies such as USD or other digital assets. However, their design creates a system of incentives for external or internal actors to compromise them.
When we hear about exchange hacks in the digital asset space, it almost always involves compromising the security of an entity that operates within the traditional server-client architecture. However, the mainstream consciousness conflates the digital exchange security with that of technology that underlies digital assets. Holding a digital asset in a cold storage is extremely secure. Holding it in an exchange is not.
3. Blockchain has low TPS, hence it will never compete with or replace traditional financial infrastructure
Traditional financial systems process a vast number transactions every day. This transaction processing capacity is called throughput and is measured by a metric called transactions per second (TPS). Payment networks such as Visa claim to process up to 56,000 TPS, while traditional exchanges are likely to have much higher capacity to process transactions to accommodate high-frequency trading.
Today, the Bitcoin network processes around 4-5 transactions per second while the second largest digital asset network—Ethereum processes around 15. If we compare the current state of the blockchain technology to the demands of the global financial industry, it is easy to see why such claims could be justified. However, this is a myopic view of this new technology, very much akin to the way Kodak dismissed digital cameras as a potential threat to its business model.
It failed to recognize (i) the speed at which digital cameras would develop and (ii) the fundamental shift the digital cameras introduced in the way we take and store pictures, despite being the company that invented digital cameras in 1975. As the history shows, that was Kodak’s grave mistake.
It is hard to ignore the historical parallels here. The digital asset space is evolving fast. The next-generation networks, which operate under the proof-of-stake consensus mechanism, preserve the securities of proof-of-work, but do away with its capacity limitations. A notable example of that is Cardano. These new networks also represent a shift in the global economic paradigm that many do not seem to notice.
4. Digital Assets Have No Intrinsic Value
The concept of intrinsic value, or lack thereof, is often used to describe digital assets as a purely speculative asset class. While this may apply, with some justification, to digital assets which only claim to function as money, such claims fail to capture the wider nature of platform-based digital assets, which derive their value from the direct use of their networks.
In digital asset platforms like Cardano or Algorand, the native token gives the holder the right to participate in the consensus of the network through the process of staking. The consensus mechanism secures the network, maintains the decentralized ledger, enables participation in the governance of the network and can sustain myriads of decentralized applications with real-world utilities.
Put simply, digital tokens may derive their value from the economic activity that takes place on their networks. The economic activity on such networks, in turn depends on the security of the network, its technical capabilities, its transaction fees and the real-world utility of decentralized applications that reside on them. In that respect, they can be thought of as a new kind of financial instrument. The kind that seamlessly combines the properties of currencies, commodities, and shares of ownership into a single digital token.
These new instruments require that we develop and apply new analytical frameworks to value them, much like the concepts of equities and derivatives did when they first emerged as new financial instruments.
5. Developed Economies Do Not Need Blockchain Technology Because They Have Well-Established Financial/Commercial Solutions.
While it is easy to see how the blockchain technology could unlock a lot of value in the emerging markets, the idea that developed economies do not benefit from this technology is short-sighted.
It is akin to saying that cell phones are a great technology for emerging markets, but developed markets already have land lines, hence do not need them. In a similar vein, we could argue that developed countries do not need internet because most of what internet could do already exists in analog form.
We have to realize that (i) at its core, blockchain is a paradigm-shifting infrastructure/technology and (ii) despite its nascent stage, blockchain is extremely cost-effective… To a degree that it has the capacity to fundamentally disrupt a slew economic sectors out of existence, from banking to real estate, and create new ones.
When we accept this eventuality, we will have to face some uncomfortable truths that many sectors will not exist in their current form or entirely disappear. Currently these sectors provide economic value, employment and generate taxes. If some blockchain-based solution is to replace them in 3-5 years, where would that value migrate? Losing them to open blockchain networks would not be acceptable politically or economically for many developed countries.
One way out of this could be for developed countries to invest in national networks, allowing them to reap the benefits of this new technology, while retaining value from economic activity of their citizens and companies within their jurisdictions.
Another, more realistic way, would be to invest heavily into friendly legal frameworks that would encourage both individuals and companies that would ultimately develop or maintain open blockchain protocols migrate to these jurisdictions, drawing in talent, capital and innovation.
One thing is becoming increasingly clear: we can no longer ignore the elephant in the room. Much like digital cameras and internet itself, blockchain is unstoppable.

Cryptocurrency Day Trading 101: Day Trading Simplified for Crypto Enthusiasts

Cryptocurrency Day Trading 101: Day Trading Simplified for Crypto Enthusiasts

https://preview.redd.it/7premb78klu51.jpg?width=800&format=pjpg&auto=webp&s=b91fb62fb384a21b7c48b6726111927185f23f18
Do you feel left out when your friends, who just tried their luck at crypto trading, go on and on about day trading until your ears start to bleed? Day trading, one of the most popularly applied trading methods in stock and commodities financial markets is now being employed by crypto traders as well. Either you are marveled by the day trading success stories shared by your friends or just freaked out by how some traders lose all their money to day trading.
What is day trading and is it worth investing your time and money in?
Find everything you need to know as a newbie crypto enthusiast in this beginner’s guide to crypto day trading.
What is Day Trading?
Trading is all about selling an asset for a price higher than its cost price. Many factors including environmental and political fluctuations, research and development, mergers, and acquisitions impact the price of an asset in the financial markets. Rather than adding value to the asset and then making a profit from it, you take the shorter route and make a profit from the price fluctuations in the market. Trading methods differ depending on how long you are willing to hold the assets.
In day trading or intraday trading, you enter and exit the market on the same trading day. Day traders keep track of the price fluctuations that happen during a day to make a small profit that adds up to a larger amount over a long period. Although traditional financial markets are only open on business days of the week for a set number of hours, the crypto market is open 24*7. To qualify as a crypto day trader, you confine yourself to a 24-hour time frame.
These two examples will help you understand day trading better.
Sonny learns from the news that the price of ABC coin is going to see a sudden, fleeting hike during the next few hours owing to a Twitter reference made by a Hollywood celebrity. He purchases 100 ABC coins for $10 each at 10:00 AM and sells it for $12 each at 10:20 AM making a $200 profit in just 40 minutes.
Mark has been keeping track of the price charts of crypto coin DEF for a while now. He decides to take his plunge into day trading and buys 200 DEF coins for $6 each. The price goes up to $7 in a few hours. Anticipating further price increase, Mark holds his coins for a few more hours during which the price dips to $6.9 and then $6.8. Mark sells the coins for $6.8 each making a $160 profit.
Crypto Day Trading Strategies
Many trading strategies are applied by different day traders to earn a profit. Let’s take a quick look at each of them.
1. Scalping
In scalping, you exploit small price fluctuations using your technical skills. Rather than focusing on fundamental analysis as these events often pan out over a longer period of time, scalpers develop a deep understanding of the market to make quick decisions.
2. Range trading
You can’t rely on price charts solely when it comes to day trading. In range trading, a careful analysis of the support and resistance a cryptocurrency receives is made to buy low and sell high. Here, you should watch out for factors that go beyond what is revealed by the price charts.
3. High-frequency trading (HFT)
In HFT day trading, you develop trading bots that enter and exit trade positions exploiting price fluctuations within a time frame of milliseconds. Although the bots are automated, a lot of work goes behind the screen like monitoring and changing the algorithms according to market changes.
Things to Know Before You Start Crypto Day Trading
  1. The cryptocurrency market is highly volatile as most crypto ventures are recently set up and yet to prove their competency. Some become a humongous success overnight pushing the prices to even double or triple while many bite the dust a few weeks into listing. Both the profit and loss you make would be significant.
  2. Don’t risk more than 1% of your total bankroll. Here, bankroll is the total amount of money you have available to invest. This will save you from losing all your money at once. Although small, your profits can be added to the bankroll to increase your income over time.
  3. Losses are part of the game. If you believe you incurred losses because of your mistake, learn from it. If external factors were to blame, accept the fate and move on.
  4. With practice comes (near) perfection. Start small and get yourself acquainted with the highs and lows of the market to improve your skills.
Ready to get started?
Day trading is one of the safest methods recommended in crypto trading, especially for newbies. If you have decided to try your hands at crypto day trading, you need to find a reliable cryptocurrency exchange that is up and running 24 hours and offers you a range of coins to trade.

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake
https://preview.redd.it/b80c05tnb9e51.jpg?width=2550&format=pjpg&auto=webp&s=850282c1a3962466ed44f73886dae1c8872d0f31
Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.

It is a good time to reflect on the departure direction of DeFi

It is a good time to reflect on the departure direction of DeFi

https://preview.redd.it/7qgmezggsnj51.png?width=700&format=png&auto=webp&s=af548c50ffe0568e2c49c6de1f14e298ae8a4ee3
In which direction should DeFi develop in the next step?
The market is changing dramatically. The past few days have been like riding a roller coaster. But after several rounds of fluctuations, the DeFi segment in the stock market is still unabated. However, the hidden worries lurking under the surface are always existing.
Almost all resources in the DeFi ecology are on Ethereum. However, there are problems with the DeFi network built by Ethereum, such as the single system performance brought by the foreseeable homogeneous sharding in the future, high gas fee, low security, and low scalability, etc. These vulnerabilities make the many applications hard to use on the DeFi network, including high-frequency trading and the transaction matching modes (We use the Uniswap asset pool model today.)
The problem with ETH1.0 is that the performance is limited, and all the transactions are mixed without any organization. Although there is composability for the DeFi applications, the network needs to operate both DeFi applications and other transactions or DApps.

Network congestion and skyrocketing gas fees

As we all know, Ethereum relies on the consumption of GAS to run its economic operation. Every step of the chain requires the consumption of GAS. Bitcoin plummeted by almost 50% to $3,800, and ETH fell as much as 65.2% just on March 12 and 13, 2020. The plummet caused a run, the Ethereum miner fees that carried a large number of DeFi and DApps skyrocketed, and the network was also congested. The Ethereum GAS fee increased to 10 times of the usual, and the GAS fee was once as high as 1 ETH to successfully package transactions. After that, because the lending operations of DeFi applications require frequent interaction with contracts, the gas fees on Ethereum have also remained high.

Problems inherited from ERC20 tokens are affecting the DeFi products on Ethereum.

If you use Ethereum’s native token ETH, the operation is simple. As long as the ETH is transferred to the contract of the target DeFi application, the contract operation will be the same as when we use cash to invest in stocks or wealth management products. No other operations are required.
However, the operation of tokens minted using ERC20 contracts is very different from native ETH, regardless of whether the tokens minted by these ERC20 contracts are well-known. Before trading, the ERC20 contract first authorizes the DeFi platform’s contract to transfer a specified number of ERC20 tokens on the account, such as USDT, USDC, or WBTC. After approval, the DeFi contract is called to transfer money. The intuitive understanding is to avoid frequent password input in small transactions, we authorized Paypal to open a password-free payment, so that the payment can be directly deducted during consumption. It sounds convenient, but is it that good?
There is a crucial problem here: if the DeFi contract is malicious during the approval process, this DeFi contract has the right to transfer all the ERC20 tokens on our account to any account. It is similar to that we authorize Paypal to perform a password-free operation of the balance, but if a hacker attacked Paypal successfully, this hacker could transfer all our money to his account. Similar things have happened before.
There is a famous project called Bancor, which used to rely on the type of authorization contract for ERC20 processing. However, there was a bug in the contract that allowed the contract to transfer the tokens in the user’s wallet to any hacker designated address after the user was authorized, which caused a loss of almost 100,000 US dollars.
The loss was not so significant because it occurred in the early stage of DeFi development. If it happens today that the DeFi asset scale on Ethereum already reached hundreds of millions, it would cause severe damage to the entire Ethereum ecosystem and the development of DeFi.

Cold shard and hot shard

DeFi needs composability, convenience, and a stronger capability of anti-run. If the throughput is insufficient, sharding technology can be introduced, which is what ETH2.0 does. However, due to the combinability of DeFi, these applications tend to aggregate into one shard, which is prone to clustering effects. This will result in different shards gathering different contents. This is called hot shards and cold shards, which are analogous to different types of cities such as metropolises as New York and Tokyo, and other places like Kyoto and Alaska. Some places have become Wall Street, while other places may become scenic or living areas. Because of the aggregation of different functions, different shards will have different features.
It is quite unwise to develop algorithms to forcibly redistribute load balancing on shards. This is equivalent to using a simple system to determine the development of a complex system, much like a planned economy. However, we can design different features in advance to make them more capable to display their own features, just as humans transformed and utilized the natural resources based on their understanding of nature, thereby improving efficiency. That means, to set up some shards with different performance and even different consensus algorithms (e.g., the features of PoW and PoS are different).
Maybe there will be a major financial shard, like London, or two other special shards with their own features, like New York City and Chicago. Financial shards require high throughput and high cost. These are called hot shards, which carry large-value transactions, otherwise, the gas fee may be too high. Most people will live in the countryside, which means cold shards here. When you need the hot shard features, you don’t need to live in Manhattan, nor do you need to travel to Manhattan occasionally. Most of the time, you will live well on another shard. When one really needs to run on a DeFi shard, it only takes a few minutes of cross-shard transactions.
But the problem generated from this is that since each shard has its own features, it may cause the shards to be independent. What we need is that shards can be harmonious but keep their differences, that is, cross-sharding DeFi needs to be achieved. Today’s multi-chain heterogeneous technology can contribute to solving this problem. Only by solving these problems can more DeFi applications be stimulated.
In our opinion, a mature DeFi platform must have the following features:
Higher Efficiency: Have faster concurrent processing capabilities, i.e., high TPS.
Lower Gas Fee: Lower gas fee can stimulate the enthusiasm of DeFi users and even catalyze the development of high-frequency trading.
More Secure: There are fewer interactive processes in the contract, at least structurally to avoid the problems ERC20 caused due to the different permissions, which leads to complicated interactions and lengthens the operation chain and increases loopholes.
Easier to Use: Various multi-native tokens can be used to pay gas fees during transactions, and thus no need to use designated tokens to pay gas fees.
Easier Combination: It can support the combination of a wide range of contracts, including the combination of different consensus in the same chain, ledger structure, and other elements, and even cross chains, making DeFi a real “Lego”.

Multi-chain heterogeneous + DeFi, one unhindered currency is helping to reach the perfect

Multi-chain heterogeneity has formed “cities” and “villages”, and DeFi has become the financial center among the cities. Since we use cities for comparison, how can we avoid each city’s independent governance and link up the chains of urban interests to form a greater network? The answer is the same as in real life, that is, the so-called currency everywhere.
Ethereum also provides currency, but this currency is not only inefficient, but also indirectly causes security risks. If you want long-term development, such a design is unreasonable.
In the QuarkChain mainnet, multi-native tokens are our primary function for building the next generation of DeFi. Multi-native tokens have basically the same status as QKC in the QuarkChain system. They can call contracts, perform cross-chain operations, and pay gas fees under certain conditions. Native tokens can achieve all of QKC’s functions, including cross-chain transactions, except participating in QKC governance. Most of the non-native asset inconvenience problems faced by Defi can be solved. In the future contracts, the functions of native tokens will be exactly the same as QKC, with the last barrier to the application of multi-native tokens being removed. This also avoids the problem of reducing the security of the entire DeFi system due to the ERC20 token’s authority issue. Next, we will launch our DEX, and then users will have the true feeling of the unimpeded DeFi platform on QuarkChain. Thus, the last piece of the puzzle of multi-chain heterogeneous + DeFi + multi-native tokens has been fulfilled, which brings cost efficiency, user easiness, and security to a new level.
Ethereum’s performance and contract security restrictions have affected development. After our repeated introduction and numerous testing, the multi-native token function is ready to be officially delivered to the community. Soon, community members can mint their own tokens and use them to transfer funds (including cross-sharding), pay gas fees, directly call smart contracts, etc. In conjunction with the DEX that we will launch in the next step, users can actually experience the convenience and innovation brought by multi-native tokens to the blockchain system.
To verify the validity of this theory, we recently launched the Game of DeFi Campaign. In the last stage of the campaign, we launched a simple DEX application and a game: QSwap — the multi-native token version of Uniswap, and Element Miner — a fun mining trading game. This is the new value that DEX and game-based mining will be able to bring to DApp and DeFi applications based on the verification of multi-native tokens with the game format. Because the gas fee is low enough, every step of the operation will be on the chain to ensure security. Meantime, instead of ETH’s high gas fee, which made users either high-cost and low-efficiency, or low-cost and low-security, the multi-native token proves the real security and convenience.
Our Game of DeFi Campaign has already entered the final stage. There are still millions of QKC reward pools waiting for the users to share. Users can download QPocket wallet to participate in this event.

Phase III: King’s Landing — Dex and Liquidity Mining

In this phase, all the community members can have the experience to use our two new products:

QSwap: Multi-native token version Uniswap

Unlike Uniswap, which can only support ERC20 tokens, QSwap supports multi-native tokens. Thus, no extra pre-authorized approval is required in the process, and any multi-native token can be used to pay gas fee ( not only QKC ). Users will get a better experience and maintain more security by avoiding granting unlimited authorization. Moreover, there will be a much lower gas fee due to sharding technology provided by QuarkChain infrastructure.

Element Miner: Interesting mining and trading DApp game

The player’s goal is to collect 5 elements to join the reward pool. However, since these elements are reinforcing to each other (just like the mining throughputs from different projects are different), using QSwap will be the most efficient approach.
One last question: This DeFi campaign uses test tokens. What if the network uses tokens with real value?

Block chain 3.0, innovative upgrading
When we mention Block chain 3.0, I believe everyone is familiar with the concept. Block chain has been praised and promoted heavily by many authoritative medias since it was created; Through the constant effects of information outburst , Block chain 3.0 is becoming a well-known concept like Bitcoin founder Satoshi Nakamoto, but the truth is, people who are able to understand Bitcoin 3.0 concept completely and apply it to actual application are considering as minority group.
So-called Block-Chain 3.0, it is actually the core of valuable internet, we can interpret it as using blockchain tenchnology for the layer structure, building a global distributive accounting system; This account system can not only record the assets transactions in Financial industries, storing data, assets origin;It can also records social networking information, product tracing, self identification verification,product ownership,all valuable information which can be recorded as code status.
This accounting system will cover every aspect of human livelihood, such as birth certification and death certification, marriage certification, education level, financial account, medical process, insurance claim, voting......etc. Most importantly, these data will not controlled by any center organization or capitalist organization, in global distributive accounting system, all data are transparent, tamper prove; Therefore, we can consider block chain 3.0 as a decentralized trust ecosystem kingdom with powerful memory ability。
From Block Chain 1.0 which represented by Bitcoin to Ethereum BlockChain 2.0, then it reaches DeFi which is between Blockchain 2.0 to Blockchain 3.0, Blockchain technology has been updating on the way to our life; Today, Blockchain 3.0 is a necessary process; Throughout the whole Blockchain industries, Blockchain 3.0 project is facing many problems, to achieve highly incorporation between block chain technology and social development, then we need to start innovating and updating based on Blockchain 3.0.
New generation public chain at business level is created because of the current time demand, which is updating the current block chain 3.0 process. Public chain ecosystem is containing 4 competitive industry advantages which belongs to Blockchain, resolving Blockchain 3.0 time problems, connecting throughout the world, to build a Blockchain Trust World which idea comes from Bitcoin founder Satoshi Nakamoto;AITD Blockchain 3.0 is going beyond the tradition meaning of Finance, providing decentralization solution for various industries to achieve" coded business economy", which means to confirm property rights, measurement and storage for each piece of information and word that represented as value, achieving public chain tracing assets,controlling and trading.
Four advantages, infinite applications.
As far as financial world concern, a widely used scenario is Global payment for BlockChain 3.0. In the current project for Blockchain industy,Rayleigh chain is the first chain to do open pay network, we can pay any types of currency on this public chain; Low transaction processing fees and high transaction confirmation speed are exceeding the tradition cross border payment industry; The emergence of Rayleigh chain is making a great contribution for blockchain global applications updating; In many years, Rayleigh business has remained stagnant, the main line ecosystem mode has been criticized for over centralizing, meanwhile, as DeFi industry is rising up, global financial ecosystem has higher standard for decentralized finance, traceability, expanding, perfecting ecosystem problems is coming one after another, Global payment update is imperative.
New generation public chain at business level "AITD Blockchain" is emerging as current time needs". AITD Blockchain is achieving new updated global open payment network, solving the current traceability, expansion, ecosystem problems and making great contribution to facilitate blockchain 3.0;The reason for achieving block chain 3.0 global payment futher goal is contributing to the 4 advantages of public chain ecosystem.
Traceable ecosystem,blockchain traceable system can upload the traceable information completely on the blockchain,enabling safe, permanent stored in decentralized data system; using one object-one code- one coin mode during transactions, which can help corporation build a safe and realible supply chain ecosystem fast, achieving block chain anti-counterfeiting, offline product verification, online traceability imagination;meanwhile, traceable information contains tamper prove, encrypted transactions, permanent storage characteristics, which can protect the authenticity of product supply chains.

Gateway functions: So-called Gateway is real world clearing house and connecting block chain online users to build trust, getting transaction channel; We can consider gateway as a single transaction station on chain, the existance of these stations is for serving on chain users; when they obtain trust from blockchain, then fast cross region payments, liquidation can be achieved,Gate way will provide digitalized assets, cross region payments, cross region transferring, allocation transactions around 10 blockchain application scenarios, improving overall cross region payments or other businesses efficiency, building greater value for global payment system; Gateway will gain economical value when provide services to users on the chain, such as obtaining interests earning, withdrawling processing fee earning, earning matching income, obtaining flow value.
Infinite dilation: The essence of blockchain is distributed information accountbook. In the Bitcoin public chain, to achieve tamper prove , transparency trait for information etc, requiring operation node to download complete block chains record, which is causing operation node to endure significant amount of pressure, turning transaction confirmation process into complicated process; Therefore, Bitcoin ,etherum congestion problems are becoming homostasis status, frequency to handle transactions are becoming the main competitive force for new generated public chain; When it is facing dilation problems, AITD public chain choose to divide nodes into four different types, sharding managment, which is to reduce storage pressure, improving operating efficiency for blocks; The design of sharding node is allowing nodes to attend its own duty, confirming transactions in faster way, alleviating public chain operation pressure, realizing infinite dilation.
Types of nodes
Ø (Collector)
In charge of receiving transaction, transfer to people who completed ranking, processing customer side SDK to start collecting.
Ø (Examiner)
In charge of trade request inspection, executing transaction and maintaining block chain, account structure.
Ø (Reserve)
In charge of inspecting and storing proposal from user side.
Ø (VISA)
In charge of administrating all the certificates(include distribution,withdrawl)
Distributed nodes design is allowing each node doing its job, ensuring transactions at a fast speed. Alleviating the operation pressure on public chain, achieving infinite dilatation.
TIPS unlimited : AITD Blockchain uses modern digital communication, block chain, mobile communication and internet of things techniques, providing convenient efficient deposit ,loan,payments, settlement,transfer ,electric invoices, digital credit , account management, currency exchange, P2Pfinance, investment financing, financial information etc,comprehensive seamless, convenient,safe, high speed decentralized financial services; AITD is revolutionizing traditional banking, becoming the leader for future finance layout , transferring traditional banks from offline to online completely, realizing all the business operations online, building a brand new decentralized banking system, the competitive advantages for decentralized banks are cancelling traditional banks physical branch through blockchain technology, meanwhile, minimising human resources cost for banks, it is concentrating on customer experiences, achieving public sharing, transparency,openess, global interconnected.
Ecosystem kingdom, connecting future
Many people like to call blockchain 3.0 as an ideal period for blockchain, In this ideal period, we can not only achieve the Trust Finance that we orginally intend to do, but also separate "Fraud" "Money gimmick" and blockchain into unrelated fields, allowing blockchain to serve for Finance like internet technology, society or new Global layer technique; adding new features for blockchain 3.0.
What types of scenarios can updated blockchain 3.0 connected to ?
First is the cross region payment problems that is seeking most attention on the way to globalization; AITD Blockchain global cross region payment is going to achieve improvenment on efficiency , lowering cost, safety tracebility etc;First,traditional cross region payment is not time synchronized, banks are usually handle transactions in groups at the end of the day. Each transaction will need 24 hours or above to complete. Second, traditional cross region payment model is consisting large amount of human account checking and depending on third organizations, which causes high processing fee, according to the report (2016 global payment ) , completing a cross region payment through correspondent banks will usually cost 25 US dollars to 35 US dollars; In monitoring aspects, there are loopholes exisiting in traditional banks which is considering as centralized organization; Above AITD Blockchain, these problems can be perfectly solved through blockchain technology; Block chain +cross region payament will achieve P2P settlements, improving efficiency, lowering cost, blockchain Transaction transparency , information publicized, transaction record permenently saved traits realizing transaction record traceability.

We talked about the advantages of AITD Blockchain global cross border payments, in the process to achieve globalized payment, assets digitalization and information sharing functions are crucial; AITD Blockchain uses blockchain technology to achieve assets digitalization, what we called token, on chain token is easier to divide compare to traditional entity assets, flowing is more convenient,minimising transaction cost at the mean time; achieving assets digitalization through blockchain technique, all assets transaction record can be released to public ,transparent,permenent storage , traceable by using blockchain technology, these traits satisified the monitoring requirement compare to traditional entity assets; AITD can also achieve information sharing function when assets digitalization begin, AITD Block chain will build a safe reliable information sharing channel through block chain irreversible traits and consensus algorithm,realizing information transparency.
To build blockchain 3.0, solving corporation financing,loan etc most commonly meet problems are the required functions for AITD Blockchain; In the whole financial supply chain, middle, small, micro sized corporations are most difficult to achieve financing, The main reason is shortage of efficient credit mechanism between Banks and middle, small corporations. AITD Blockchain's mission is building Trust between loan providing financial organization and small, micro coporation;AITD Blockchain is building completely supply chain financing system, ensuring data reliability of supply chain core coporation through blockchain private key signature techniques, uploading contract, invoices on the chain, achieving value delivery for assets digitalization; After blockchain is solving data reliability and value flow, banks and other financial organizations will not process single evaluation for middle, small size corporation, but they are evaluating through core corporation's will of payment , invoice and data on chain, middle, small, micro corporation financing memorizing, achieving transpassing from single node financing to whole chain financing, therefore minimising the financing cost and solving financing difficulties.

During this technical world, bitcoin is the foremost used digital currency all over the world. However the main question then arises within the minds of the many folks is why bitcoin is considered the foremost superior over other cryptocurrenc Bitcoin Freedom
Bitcoin is that the one method of creating transactions daily as alternative currencies. But it's its options and uniqueness that make it superior. Bitcoin and different currencies are based mostly on the cryptographic algorithms or mathematics that are encrypted, with that the user becomes the owner of the currency. Bitcoin currencies are easily accessible at Bitcoin ATM and online exchange
The main feature of the bitcoin, which makes it superior is that it is the safest option for digital transactions. These will be used for on-line searching and transfer of money too.
There are many alternative blessings to using bitcoin. A number of them are mentioned below
Decentralized and digital
Bitcoin offers the freedom of exchanging the price without representatives that proves helpful in controlling the lower fees and high funds. Bitcoin is that the faster method of transaction than others. It is secure as it is free from theft and frauds and is constant. The main advantage is that bitcoin has its homeowners whereas the bank controls the money.
Makes online looking
Normally, bitcoin will be used for on-line shopping too. Bitcoin is the opposite face of e-wallet, that is created by blockchain technology that is used to store money and will easily pay everywhere digitally. For this reason, it also makes your searching easy by which you'll be able to look from your home solely

Bitcoin is created by blockchain technology. Blockchain is the sole technology which will either make it or break it. There are many computers which are used to keep up a permanent record of each bitcoin transactions with the help of cryptographic technique. In this approach, it becomes a lot of valuable together with the tracking of the payment. At the same time, there's no method of tracking the cash

While not any transformation method, it will be used over the entire world. It provides the simplest platform for the investment as it is free from the restrictions of governments or banks. It provides an open market and combines the simplest of gold and money.

Bitcoin provides the power to access the balance of the users with a password which is named a personal key. It additionally permits the exchange of values through the web without any middle person. Thus, bitcoin becomes safer, stuffed with privacy, and open to everyone
Unlike cash, it is not possible to form the duplicate quite bitcoin that makes it more efficient. It's protected with the technology of blockchain. Even if anyone tries to form a replica of bitcoin to use it, then the system will automatically reject it as the system recognize it as unknown

Bitcoin Freedom failed to allow two persons to transact on the one price. Once the bitcoin is transferred, its possession is also transferred. So this is the simple approach of maintaining records for any tax functions. It conjointly makes it a easy and healthier metho

Filecoin | Development Status and Mining Progress

Author: Gamals Ahmed, CoinEx Business Ambassador
https://preview.redd.it/5bqakdqgl3g51.jpg?width=865&format=pjpg&auto=webp&s=b709794863977eb6554e3919b9e00ca750e3e704
A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it.
Filecoin announced, that there will be more delays before its main network is officially launched.
Filecoin developers postponed the release date of their main network to late July to late August 2020.
As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process.
Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market.
Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors.
The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020.
They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit.
The Filecoin team noted the following:
“We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks.
Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet.
The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020.
The updates to the project can be found on the Filecoin Road Map.
Filecoin developers stated:
“This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage.
Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain.
In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards.
Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21.
Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price.
Mining in Filecoin
In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency.
Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data.
Filecoin will contain several types of miners:
Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out.
Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power.
Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network.
The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into.
In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.

Hardware recommendations

The current system specifications recommended for running the miner are:
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars.
Proceed to mining
Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract.
Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually.
After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started.
Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page.
At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention.
Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt.
Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network.
Duration of operation, cutting and penalties
“Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network.
In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error.
Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily.
An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection.
The sector will pay an error fee after the penalty of the sector once the error is discovered.
Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network.
Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function.
Filecoin miners
Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.”
With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices.
Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless.
Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers.
Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network.
However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners.
These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB).
Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development.
“Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital.
“Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said.
Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT.
In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive.
To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day.
As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force.
The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million.
This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs.
After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020.
The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process?
Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance.
In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners:
The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue.
It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown.
It seeks to promote mining using Filecoin Discover
Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day.
Ian Darrow, Head of Operations at Filecoin, commented on the announcement:
“Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”.
Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more.
Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds.
In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations.
The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested.
“The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”.
IPFS and Filecoin
Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure.
IPFS
It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live.
The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides.
Using IPFS
In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data.
Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service.
Using Filecoin
The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone.
Filecoin, powered by IPFS
It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS.
Some advantages of sharing Filecoin with IPFS:
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol.
Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated.
PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage.
In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected.

Market maker: who is it and what function do they perform?

Market makers have become as a key link in the financial markets. There is a misconception that market makers can influence the price of assets. In fact, this statement is far from reality. The main task of a market maker (MM) is to provide liquidity of any asset. If an asset traded on an exchange is provided with sufficient liquidity, the price and spread will be at an adequate level. If there is no liquidity — it will not be profitable to trade an asset, the price will stop at one mark and the spread will expand. So, what exactly do market makers do? Let’s analyze in more detail in this article.

Definition and responsibilities of the market maker

A market maker (MM) is a firm or individual who actively quotes two-sided markets in a security, providing bids and offers (known as asks) along with the market size of each. The profits of the market maker is made up of several aspects:
  1. Payments from the exchange as stipulated in the cooperation agreement.
  2. Spread from the execution of orders.
  3. Speculations and investments.
The SEC regulator explained the functions of the market maker — willingness to buy and to sell an asset on a permanent basis, at a public quote. In other words, maintaining an adequate level of supply and demand, as well as confrontation with the market, for example, selling bitcoin in case of its rapid growth or buying in case of a fall.
In addition, the market maker may act as an intermediary seller or a buyer in case of absence of one of the parties. If you decide to buy or to sell an asset on the exchange and your transaction has passed within a second, the market maker is acting as an intermediary. In this way, the liquidity providers remove unnecessary delays and difficulties in exchanging assets.

Market maker trading process

For example, there is a buyer on the exchange who is ready to buy 100 ETH and there is a seller who is ready to sell 90 ETH. The task of the market maker is to add 10 ETHs and to provide a price to a buyer, for example $200 and for a seller, for example $199. The buyer will pay $20,000 and receive 100 ETH, and the seller will receive $17,910 and give back 90 ETH. The market maker will receive $2,000 for the 10 ETHs and $10 spread, for providing liquidity. The liquidity provider makes a lot of such a trades a day, and as a result has a good profit. However to do this, you need to have an impressive stock of assets to maintain a level between supply and demand. With such not complex machinations, the market maker ensures the efficiency of financial markets, maintaining an adequate price for the asset and the minimum price divergence between exchanges.
Based on the above example, we can think that the activity of a market maker is not complicated and a stable way of earning, in the presence of impressive capital. However, this is not quite true. During time when the market is very volatile, liquidity providers can suffer losses. For example, there is a buyer on the exchange who is willing to buy 100 ETH and a seller who is willing to sell 10,000 ETH. A buyer buys 100 ETHs at $20,000 (price for 1 ETH $200) and a seller gets $19,990 (price for 1 ETH $199), the market maker gets $10 as a spread. At the same time, there are 9,900 ETHs left, which the seller wants to sell, and the market maker, respectively, must buy them back. Having paid $1,970,100 for the entire offer (price for 1 ETH is $199), the liquidity provider will not be able to sell them for the same price. Even if the price drops to $198.5, the total sale price of 9,900 ETH will be $1,965,150, with a loss of $4,950. Considering that the crypto market is famous for its volatility, the price difference may not be 50 cents.
A market maker cannot simply sell the ETHs they receive at a reasonable price for the following reasons:
  1. No one will buy the asset at an unfavorable price, and a sale of 9,900 ETH is likely to have impacted the market.
  2. The exchange’s service agreement states that the market maker cannot simply take and sell the assets, otherwise its services may be refused.
  3. This method can be considered as market manipulation.
Therefore, in a moment of strong volatility market makers simply leave the market, otherwise — it can lead to a serious loss. During high market volatility, it is often impossible to close a position at the right price, due to the lack of liquidity on the exchange. This indicates that the market makers have withdrawn from trading.
It is also possible to track the presence of a market maker on the exchange in the following way: if the spread is narrow and the price of an asset is in a sideways trend, the liquidity provider participates in trading on the exchange. If the spread is wide and the price of an asset is subject to volatility — the market maker has withdrawn from trading. In the same way, you can find out whether there is a market maker at the exchange at all, i.e. whether they resort to its services.
The Market Maker performs vertical market analysis, not horizontal market analysis as ordinary traders do. For the liquidity provider, in addition for buying or selling an asset, the order glass displays pending orders, Take Profit and Stop Loss. This allows you to correctly interpret the mood of the market participants and perform your direct duties as a market maker — to maintain liquidity levels and narrow spreads, as well as to provide large volumes of orders.

Market makers on the crypto market

Market makers in the crypto market are much more in demand than the traditional market and that’s why. If we talk about crypto currencies from the top 10 list — their liquidity is enough to buy or sell a coin almost instantly. However, there are about 3,000 crypto currencies for 2020 and not all of them are liquid.

The process goes like this:

Startup is going to be carried out by IEO (Primary Exchange Offer), a modern analogue of ICO. The stock exchange considers the token and leaves it. After a week, a month, six months the amount of investment in a token is minimal. There are two reasons for this:
  1. A skilled trader, when investing in a new coin, will rely on the order book. As the token is new, even if it is promising, but there are no records of selling and buying, so the trader will refuse to invest.
  2. A significant player has learned about the listing of a new token and its future prospects. It was decided to open a large, long term position, but there is no liquidity, that is, if the position is opened, it will be time consuming.
To avoid such a development, the crypto market should resort to the services of market makers. Liquidity providers may buy a token and artificially “fill” the order book. In fact, this will be a twisted indicator of liquidity and is suitable only for speculative purposes. But 90% of cryptotraders came to this market because of its high volatility, i.e. to earn on price hikes.
For this reason, crypto currencies need the services of market makers for the systematic establishment of the market and attraction of new, professional traders.

Strategies used

As a rule, market makers always resort to ATS (Automated Trading Systems) and HTF-trading (High Frequency Trading). Both systems require very advanced programming skills. In addition, it will require economy knowledge, preferably not minimal, in order to make right assessment of work and potential risks.
Sell-Side strategy — automatic trading systems are used to constantly maintain optimal prices and profit from spreads. It is not rare to have a strategy of placing Buy and Sell orders simultaneously. In fact — a common risk hedging.
HFT or high-frequency trading- is a type of algorithmic trading characterized by a high speed and turnover of capital, as well as short asset holding periods. To become an HFT trader you will need specialized robots and powerful computers as the main task of high-frequency trading is to conclude a lot of transactions in the shortest possible time. With the help of HFT trading market makers must set a quote or the last price and constantly update it.

Conclusion

Market makers are a necessary part of the economy. They do not earn on price movements, but create comfortable and loyal conditions for trading. In the end I would like to tell you about some myths that exist in the network in relation to market makers.

Market makers can affect market quotes

That’s true, however in a slightly different understanding. The task of a market maker is to create the market mood and push its participants to open orders in the right direction. Market makers cannot influence the quotes price for two reasons:
  1. The exchange where the market maker trades, monitors all its operations. In case of intentional influence on the price of the asset, the reaction will be immediate.
  2. This kind of activities are trade manipulations, i.e. they are prosecuted by state regulators, up to including deprivation of license to operate such activities.

Market makers cooperate with each other

At the beginning, I would like to mention that all market makers are competitors, and to disclose their plans to competitors is not a good idea. In addition, it is also punishable by law, up to deprivation of a license to conduct activities.

Most transactions on the platform are initiated by market makers

It’s not a very clear statement. The main profits of a market maker is spreads. How in this case should the liquidity provider earn, if all transactions on the site belong to him?
These are the most popular myths in the network regarding market makers. In the end I would like to add that the work of the market maker — is a complex and time-consuming process, the result of which is a balanced financial market.

The Block Time of BCH should be Shorten(建议缩短BCH出块时间)

The Block Time of BCH should be Shorten(建议缩短BCH出块时间)
As we take BCH as a convenient and fast p2p e-cash, we have to shorten the block time as soon as possible.
BCH想成为方便快捷的点对点电子现金,应该尽快缩短出块时间。

https://preview.redd.it/8m6a28kpjkb31.png?width=541&format=png&auto=webp&s=a30d0604120a5e13989a102b9d2c283752369ec5
BCH's current block time is 10 minutes. Since BTC, BCH and BSV chains use the same SHA256 mining algorithm and the BTC is larger, the real block time of BCH which as a small chain will severely fluctuate when the price changes. In the past week (1000 blocks), there were 61 times out of 30 minutes block time, 22 times up to 45 minutes , and eight times in more than an hour. The longest block time was up to an hour and 38 minutes!
BCH现在的区块时间是10分钟,由于BTC、BCH和BSV三个链都使用SHA256挖矿算法,且BTC的规模更大,所以在价格波动时,作为小链的BCH的出块时间会发生大幅波动。在过去的一周内(1000个区块),BCH的出块时间超过30分钟有61次,超过45分钟有22次,超过1小时则达到8次,几乎每天都会遇到,最长达到1小时38分钟!

https://preview.redd.it/hs77dytqjkb31.png?width=864&format=png&auto=webp&s=4f064cc1388ff94a52110c7a5c6a52597575707d
Even the situation of BTC is much better than BCH. At the same time, the block time of more than one hour happened only two times. Moreover, BTC holders have almost given up the payment function of the main chain, instead using BTC as a value storage tool, and they are ready to wait for all the time. But BCH is prepared as cash for payment!
连BTC的情况都要比BCH好很多,同样的时间里,超过1小时的出块时间只有2次。并且,BTC持有者已经几乎放弃了主链的支付功能,把BTC当做价值存储工具,他们做好了等待的准备。而BCH却是要做支付工具的!

https://preview.redd.it/aak8b40sjkb31.png?width=864&format=png&auto=webp&s=c159024b55fb14c6af04861143f4a43c6c4521e9
In a BCH payment case where more than one confirmation is required, the user often encounters an hour to confirm. This is intolerable in modern society at a high frequency trading. As far as I know there are at least three cases using BCH require more than one confirmation, instead of zero confirmation:
在需要1个以上确认的BCH支付场景中,用户时常遇到1小时才能确认。这在高速运转的现代社会是无法容忍的!就我所知,至少有三种BCH交易场景要求1个以上确认,而不能采用0确认:

1)Exchange top-up. All exchanges now require more than one confirmation in cryptocurrency top-up. Generally, exchanges will require six confirmations and BCH-friendly exchanges (such as Huobi) require three confirmations to be received when BCH supporters' exchanges (such as Coinex) require only one confirmation.
1)交易所充值。现在所有的交易所都要求密码货币1个以上确认才能充值到账。一般交易所会要求BCH充值6个确认到账;对BCH友好的交易所(比如火币)要求3个确认到账;BCH支持者的交易所(如Coinex)要求1个确认到账。

2) Local.bitcoin.com wallet top-up. When I received an OTC order in local.bitcoin.com but my balance was insufficient, it turned that I had to top up soon as possible. This top-up required one confirmation before I can use it. However, waiting for more than 30 minutes is likely to cause the OTC order to fail.
2)local.bitcoin.com钱包充值。当我接到一笔OTC订单,但我在local.bitcoin.com的余额不足时,我必须尽快充值到local.bitcoin.com钱包,这个充值要求1个确认后才能使用。等待30分钟以上,就很有可能导致这笔OTC交易失败。

3) Bitpay wallet top-up. I had to top up in the Bitpay wallet for shopping when there was not sufficient balance, it had to be waited for more than 30 minutes, then I would rather pay in another way rather than BCH.
3)bitpay钱包充值。当使用bitpay支付渠道购物时,遇到bitpay钱包余额不足,我必须先充值到bitpay钱包,等待1个确认,然后才能支付。如果1个确认需要等待30分钟以上,那么我宁愿用bitpay之外的方式支付了。

Regardless of the exchange wallet, local.bitcoin.com wallet, or Bitpay wallet these are hot wallets. An experienced BCH user will not save a lot of bch in the hot wallet. Therefore, the more frequently users who use the BCH for transactions and payments, the more frequently they will face the top-up confirmation waiting time of 30 minutes or more. It is enough to drive away the most loyal users of BCH in the long run, unless they only hold coins and rarely trade and pay.
无论交易所钱包、local.bitcoin.com钱包,还是bitpay钱包,这些都是热钱包。一个经验丰富的BCH用户不会在热钱包存大量的bch。因此,越是频繁使用BCH进行交易和支付的用户,就越要频繁面对30分钟甚至1个小时以上的充值确认等待时间。长期这样,足以赶走BCH最忠实的使用者,除非他只囤币,很少交易和支付。

In fact, the cases requiring one confirmation is much more often than the above three. Although the small consuming payment can accept 0 confirmation, almost all wallet top-ups require more than one confirmation. The long waiting time for confirmation is the worst part of the entire BCH business cycle.
实际上要求1确认的场景远不止以上3个,尽管最终的小额支付可以接受0确认,但几乎所有的钱包充值,都要求1个以上确认。漫长的1确认等待时间是整个BCH商业循环中最糟糕的环节。


https://preview.redd.it/eqddt3wnvkb31.png?width=1362&format=png&auto=webp&s=48af0e4594c6e82a5a0fbb77d6ba349d0e13269c

When the block time is shortened from 10 minutes to one minute the BCH payment experience will be greatly improved even if the exchange and wallet will increase the one confirmation to 10 confirmations. According to Doge's data, in the last 1000 blocks the fluctuations of the 10 blocks accumulated time ranged from two minutes to 17 minutes. It is far superior to the one confirmed condition of the current BCH.
当区块时间从10分钟缩短到1分钟时,即使交易所和钱包将1确认相应提高为10确认,BCH的支付体验也会有很大改善。从Doge的数据看,在最近的1000个区块中,10个区块的累积时间波动范围在2分钟-17分钟之内。远远优于现在BCH的1个确认的状况。

https://preview.redd.it/kfs4q1b1kkb31.png?width=864&format=png&auto=webp&s=c46a3de89906ee65ba21f3af647575eb40ca879d

More importantly, in fact, exchanges and wallets will not increase the number of confirmations to 10 when BCH shorten the block time. I asked the CEO of Coinex Haipo Yang "Coinex now asks one confirmation for BCH top-up. If the block time of BCH is shortened to one minute, how many confirmations will be asked?" He immediately replied "One confirmation will not be changed, even LTC is one confirmation now".
更重要的是,实际上交易所和钱包并不会因为BCH出块时间缩短到1分钟,而将确认数提高到10个。我询问Coinex CEO杨海坡“Coinex现在要求BCH充值1个确认到账,如果BCH缩短到1分钟出块,Coinex会要求几个确认到账?”他立刻回答我“不会改”,现在“LTC也是1个确认”。

In fact, exchanges and wallets are more concerned with ‘confirmed on blockchain’ than ‘several confirmations.’ Most wallets and exchanges do not increase the number of confirmations when BCH shortens the time. This is a troublesome and unnecessary thing. If most exchanges and wallets are able to maintain the number of required confirmations, the user experience of BCH will increase dramatically. According to the data of Doge's last 1000 blocks, the block time within 2 minutes accounted for 85.4% and the maximum time is no more than 10 minutes.
实际上交易所和钱包更在乎的是“链上确认”,而不是“几个确认”。多数钱包和交易所并不会因为BCH缩短时间而相应提高确认数。这是一件麻烦而又不必要的事情。如果多数交易所和钱包能够保持1个确认的要求,那么BCH的使用体验将大幅提升。根据Doge最近1000个块的数据,2分钟以内的出块时间占到了85.4%,最多也不超过10分钟。

https://preview.redd.it/hajx2443kkb31.png?width=864&format=png&auto=webp&s=740c2d3351610220966b5c9d17e24613d16757ea

In the Chinese community we have had a lot of discussions and most BCHer are eager to shorten the block time and wait for more people to support. But their patience is limited that I have seen some staunch supporters losing because of the lack of positive response to shortening the block time. They have experienced the toughest hash war and adhere to the ideal of BCH as the world currency. But now, when they promoted BCH to others as ‘convenient and fast electronic cash’, they often encounter great embarrassment that they have to wait for a confirmation for more than 1 hour and they can't even convince themselves !
在中国社区,我们已经进行了大量的讨论,多数人急迫的期待缩短出块时间,并等待更多人的支持。但人们的耐心是有限的。由于缩短出块时间一直缺乏积极的回应,我看到一些坚定的支持者在流失。他们经历了最艰难的算力大战,坚守对BCH作为世界货币的理想。但现在,他们向别人推广bch是“方便快捷的电子现金”时,经常遭遇BCH1小时不能出块的尴尬,他们开始连自己都无法说服了!

We all know how simple and urgent to expand block capacity in 2016. This is the reason for the birth of BCH. Now we are facing a similar situation on the shortening block time of BCH. When the block is shortened to one minute the users can get the waiting time reduced by 90 percent in many cases and no longer worry about waiting for an hour. Why not do it right away?
我们都知道2016年扩大区块容量的逻辑多么简单而又紧迫,那是BCH诞生的原因。现在BCH缩短出块时间面临类似的情况,出块缩短到1分钟,用户就能在很多场景中减少9/10的等待时间,不再为1个小时的确认等待而苦恼。为什么不立即去做呢?
