Although according to our previous estimates (https://www.chainnews.com/articles/115931150768.hpolygon coin hangi borsadatm), Arbitrum's transaction cost can still be reduced by about an order of magnitude compared to the first layer of Ethereum, but according to the statistics of the L2 Fees website From a point of view, it is still several times higher than the cost of using some ZK Rollup networks.However, you can also see that the L2 Fees website has also made some notes for Arbitrum. Arbitrum One, which is in the Beta stage, is currently artificially restricted. The opening of this restriction on the official mainnet in the future may further reduce transaction costs.
We also asked the Arbitrum team about this topic. They said, "In the short term, we are working hard to reduce the basic cost of each transaction, that is, the cost allocated to each transaction in the batch release transaction. We will soon see Transaction costs have fallen.”However, in the long run, the Arbitrum One solution requires that each transaction be stored on the Ethereum mainnet through calldata. As long as the capacity of Ethereum remains unchanged, there is still an upper limit. Therefore, the long-term expansion possibility of Arbitrum One still needs to rely on the data sharding technology of Ethereum 2.0.The Arbitrum team stated, "ETH 2.0 data sharding will greatly reduce the cost of publishing data to Ethereum, which is crucial to Rollup's expansion technology. ETH 2.0 data sharding means cheaper calldata, and we are very happy to become Ethereum "Rollup as the center" part of the road map."Are there more expansion plans for Arbitrum?The upper limit of Arbitrum One is restricted by Ethereum. Is it possible for other types of expansion technologies to open the ceiling of Rollup?
Teams have already begun to explore more efficient expansion solutions than Rollup. Although a little security may be sacrificed, the results obtained are quite significant. For example, StarkWare's StarkEx solution, through cooperation with dYdX, provides a perpetual contract transaction experience without paying for Gas in the second-tier network. Matter Labs will also introduce zkPorter technology in zkSync 2.0 to reduce data availability, but the cost can be reduced even more.Matter Labs' zkPorter off-chain data solutionBut there is another feature. If the price of Bitcoin increases, the price of USDT will decrease and then slowly return to the average value. If the price of Bitcoin falls, USDT rises instead.
This means that in some characteristics, the price of bitcoin has risen, and there are more shippers, so more USDT is exchanged through the acceptor, and the acceptor will continue to reduce the U price.In the stable currency trading market, buying and selling USDT will definitely show different prices. The spread is the profit of the acceptor.This income method will also be used as the core business of many wallets, mainly in the compliance area to complete the sale of cash to stablecoins and tokens such as Bitcoin and Ethereum.With a huge total transaction volume, the wallet can earn huge profits by charging fees.
So as long as there is a variable of acceptor in the stable currency market, the price of stable currency must fluctuate up and down. But because if the stable currency in the exchange trading pair is a legal currency anchored stable currency, it may not need to carry too much floating risk. But in the process of transaction, tokens are directly exchanged for legal currency value.It is also because, for example, USDT is a stable currency token between tokens and fiat currency, and the exchange market of USDT is a floating market, which brings about the unstable price performance of stable currency that users understand.
What about designing a stable coin to make the price the most stable design?The answer should be no, because as long as it is a stable currency issued and accepted by a trusted subject, the absolute stability of the price cannot be guaranteed, and the absolute stability of the price also means that there is no market profit margin, and it is impossible to develop a perfect business ecological structure. For example, if the ratio of USDT to U.S. dollar has no price fluctuations. The user using US dollars is the same as using USDT.The result of this is that there is no spread when the acceptor buys and sells USDT. In other words, in the exchange, there is no need to introduce an over-the-counter market, but a stable centralized exchange pool can be established directly by the acceptor. However, the most suitable role for establishing an exchange pool is the exchange itself.If you individually design a stable coin with less volatility, there are some feasible solutions. The general logic is:
If it is a centralized issuer and operator, on the basis of ensuring the scale of liquidity, it does not design an acceptance market, but only charges a small fee through a centralized pool.If it is a decentralized issuer and operator, it needs to ensure continuous issuance and maintain sufficient reserve assets and insurance assets for the issued stablecoins. The insurance assets are used to maintain the price of stablecoins and have been stable at the same level as the legal currency. 1:1 anchoring relationship within the range of small fluctuations.If losses are caused by huge fluctuations, insured assets are needed to complete subsidies and compensation, or to supplement the shortage of reserve assets.Stable currency is an important role in the cryptocurrency world and a bridge between cryptocurrency and real finance. Today's stablecoin scale continues to rise, which is one of the important growth signals of the cryptocurrency market. The maturity of stablecoins has reason to become one of the necessary conditions for the growth of cryptocurrencies.
But today's stable currency market is far from becoming a regulated market. Decentralized stablecoins are generally used for mortgage lending or to provide transactions in a single process in other types of defi applications, which do not reflect their maximum capabilities. Centrally issued stablecoins require mature supervision. Prevent the various risks that finance may bring.Certus One initially introduced the Wormhole L1 native bridge in 2020. After auditing and going online, holders of SOL and ERC 20 tokens can now transfer their assets between the public chain ecosystem, not just Solana and Ethereum. With the launch of the Wormhole mainnet, the bridge is expanding to other L1s beyond Solana to bring liquidity from Solana, Ethereum, Terra and BSC. They are working to help developers provide more DeFi applications and a more powerful Web 3 experience.
Solana's Wormhole bridge was first released by Certus One in October 2020, and Wormhole V2 recently announced the launch of the mainnet. The new version of Wormhole is a cross-chain bridge, which provides cross-chain liquidity. Transition from Solana to Ethereum Bridge into a native L1 bridge.The new version of the Wormhole Bridge has tremendous flexibility in the Web 3 industry. The cross-chain liquidity bridge aims to have its own security model, incentives and applications by supporting applications. Since Wormhole aims to support more L1 networks in the future, they can support more than just bridged network applications.
Wormhole V2 is separate from the original native bridge built on Solana. It is completely redesigned and has more applications. The Wormhole team uses an oracle/smart contract-based system. This requires trust in the oracle network-not the blockchain.Wormhole V1 is just a native L1, but third-party applications are calling for a way to transmit NFT and other ERC-20. They are also looking for transfer insurance pools and different design mechanisms to ensure that it is necessary to build a different bridge with more accessibility.With the launch of Wormhole, it will provide all of the above services for Terra, Solana, Ethereum and BSC. In addition to providing liquidity to other ecosystems, the Wormhole team is ready to expand into other areas and provide incentives for their own set of validators. It is worth noting that it is not backward compatible.When a bridge has its own security model, it will make the bridge more complex and flexible to solve the traditional problems of the bridge: low transaction costs, fast relay transactions, and accurate data provision. A bridge with its own security model is a robust and secure transaction bridge.Wormhole V2 has its own consensus mechanism, called Guardians. This new feature makes it an independent bridge with the functionality and flexibility of connecting to any other network, while allowing developers to build their own dApps on the bridge.The bridge will provide basic messaging functions, and then developers can build a token bridge on these foundations. There are two ways to transfer tokens on the bridge. For the transfer-out transaction, the native token will be locked in the smart contract or destroyed and expressed as a packaged token. This transaction will generate a transmission message to the bridge-thus sending the message to another chain.
For incoming messages, the user needs to send a message containing the payload. It's simple-you need to send a message with one of four options to tell the bridge what you want to do; unlock or mint tokens, register token bridge contracts, upgrade contracts, or send metadata messages.Another feature of this design is that developers can build applications on the bridge without major changes to a single protocol. This opens the door for connections between networks—such as token or NFT exchanges or connections from a single chain to a specific set of chains—such as price streams or data sources.
L1 needs additional help from other networks to increase their DeFi use cases. Because of Solana's high throughput, they emphasize small transactions. Higher speed means that validators can process more transactions in a block. This is in sharp contrast to Ethereum, which has only so many transactions in a block, which pushes up the gas price and takes time to process transactions.With this bridge to Ethereum, Solana, Ethereum, Terra and Binance Smart Chain, Solana should see more users bring their ERC-20 tokens into Solana's ecosystem. Solana is L1, which means that it is the first layer protocol that allows developers to use Solana's features to build applications.
Wormhole's modeling method complements the Cosmos Hub and IBC. Although the Cosmos Hub and Cosmos SDK related chains use IBC, the chain can connect to the Cosmos Hub and other chains by running a light client. Wormhole runs a separate chain designed to connect to chains that don't have built-in IBC capabilities. Currently, L1, which cannot be connected to each other, relies on bridges to achieve cross-chain communication.Wormhole's goal is a chain without light clients or other chains that may be compatible with IBC. It aims to connect many high-value chains that focus on DeFi. More transaction volume and increased liquidity on these networks will help continue their growth trajectory. However, the best way to increase the use of these networks is to adopt more. In order to address more adoption and increase the choice of Web 3, the bridge is the key to providing a user experience beyond Web 2.
According to reports, David Marcus, the head of Facebook's cryptocurrency business, said in an interview a few days ago that "stable coins" still need more supervision, which should focus on consumer protection and prevention of illegal payments such as money laundering. .Marcus said: "Do we need more supervision? The answer should be yes. First of all, consumers must be protected. Do consumers know what they are buying? In unfavorable circumstances, what guarantees do they need to protect Take out the money? So, when it comes to'stable coins', one has to know what its reserves are made up of?"The so-called "stable currency" is a digital cryptocurrency that is not affected by price fluctuations. They are inherently stable, and this stability usually comes from the support of some alternative value, such as pegging to the dollar or commodities.Launch digital wallet first this year
In June 2019, Facebook released a digital cryptocurrency called "Libra". Libra was originally planned to be officially launched in 2020 and is expected to provide digital transaction and payment services to billions of potential users. But then, many central banks, finance ministers, legislators, and many privacy protection agencies around the world raised questions about Libra and listed multiple issues related to Libra, including money laundering, terrorist financing, and financial stability.In April last year, the Libra Association announced an adjustment to the Libra project. After the adjustment, it will support multiple versions of digital currencies, that is, a "stable currency" backed by a single currency. In contrast, Facebook’s initial plan was to get Libra to get a mix of currency (US dollar, euro, Japanese yen, British pound and Singapore dollar) and government debt.
In December, Facebook changed the name of "Libra" to "Diem". At the same time, the "Libra Association" responsible for launching and operating this digital cryptocurrency was also renamed "Diem Association". A person familiar with the matter said in April this year that the Diem Association plans to launch a pilot service for a single stable currency pegged to the US dollar later this year. The initial pilot scale will be small and will focus on transactions between individual consumers.Marcus said at the end of last month that Facebook will go all out to launch the digital wallet "Novi" this year to help the company's 2.9 billion users store digital cryptocurrencies. And diem will be launched after Novi.
Stablecoins may be regulated as securitiesEarlier this week, US Securities and Exchange Commission (SEC) Chairman Gary Gensler (Gary Gensler) gave a wide range of opinions on potential digital cryptocurrency regulation during a Senate hearing. Gensler said that "stable currency" may be considered a security. Gensler's remarks come at a time when the US Treasury Department is working with other federal agencies to draft a potential regulatory report on "stable coins" by next month.
At the Senate hearing, when asked about the "possibility of cryptocurrency investors trying to withdraw funds during the market crash," Gensler said that the SEC cannot provide investors with much help because cryptocurrency trading such as Coinbase The firm is not yet registered with the SEC.And Marcus said that the risk of investing in "stable goods" depends on the commodities that support "stable coins". He said: "In my opinion, only'stable coins' backed by cash and very short-term national debt are high-quality'stable coins."Marcus also said that concerns about the use of "stable coins" for illegal payments also provide regulators with an opportunity to increase the transparency of regulations governing such transactions, although the current use of "stable coins" for daily payments is still rare.Four major studios, Tianmei, Photon, Northern Lights, and Rubik's Cube, are dispatched
Whether it can be realized technically, put it aside, anyway, the concept of "Metaverse metaverse" is on fire again.First, Zhongqingbao, Tom Cat, etc. revealed that they are optimistic about the development direction of Meta Universe. The capital market took advantage of the trend. The stock prices of many A-share game companies have skyrocketed. Later, Pico, the largest domestic VR equipment manufacturer, issued a letter to all employees, disclosing that the company was beaten by Bytedance. Acquisition, it is reported that the purchase price is as high as 9 billion.
CCTV Financial Channel reported that when the technology giants explore the commercial operation of space travel, another internalization path that may change people's living environment will detonate the technology circle this year, and that is the "meta universe".This also made the "meta universe" fire on the table.
It is worth mentioning that a number of well-known manufacturers have recently been reported to have registered Yuan Universe trademarks, such as Tencent’s "King Yuan Universe" and "QQ Yuan Universe", Mihayou’s "Mi Universe", and iQiyi’s "Qing Yu Yuan" "Universe" and the "End-Dollar Universe" of the Perfect World, etc.In addition, according to a competitive inquiry, it was found that game products/brands owned by a number of major Internet companies were preemptively registered as Yuan Universe trademarks.
