When talking about L2, if Optimisethereum transaction vs internal transactionm and Arbitrum are not mentioned, it is obviously inappropriate.
When using the Optimism netwoethereum price can hit 14krk, the following two points are completely different from Ethereum. You must be clear:First: The transaction is processed according to the first-in-first-out principle, so increasing the gas price will not affect the execution speed of the transaction.
Second: Currently, Optimism uses gas limit to encode information about transactions executed on L2 and on L1 post transaction cost information, so do not try to modify the gas limit automatically provided by the application, otherwise your transaction may be rejected.Proof mechanism: fraud proofOptimism advantage: Data is stored on the main chain, and it is easier to support general smart contract technology.Optimism challenge: The exit period of the second layer is long (7 days). This is also a problem faced by all Layer 2 solutions that use fraud proof mechanisms. The overall security is slightly lower than that of the main chain and ZK solutions.Arbitrum was originally an academic project at Princeton University, established by the team Offchain Labs.
Arbitrum's proof mechanism is similar to Optimism above. The difference is mainly reflected in the difference in the data uploaded to the main chain. In the process of processing, when someone thinks that the second-level data is in dispute, they can pay a deposit and submit a proof. At this time, the contract will arbitrate it. In the Optimistic Rollup scheme, a complete contract will be simulated and executed on the main chain. Calling consumes high costs; in the Arbitrum Rollup scheme, firstly, through multiple rounds of interactions at the second layer, the dispute scope is reduced before being simulated on the main chain, the number of interactions is reduced, and the cost of dispute resolution on the chain is reduced. This is the biggest difference between the two schemes.In May of this year, Arbitrum was opened to developers for the first time. On September 1st, the public beta was launched, and the whitelist mechanism was also offline. Similar to Optimism, Arbitrum currently has a clear limit on the upper limit of network processing capacity (80,000 arbgas/s), which roughly matches the current capacity of Ethereum L1, but Arbitrum also stated that as the system becomes stable, the speed limit will be gradually increased in the future. , And continue to improve performance.Cryptocurrency games, such as Axie Infinity and Alien Worlds, have exploded. You first buy three Axies, which are cute cartoon animals, and then you can breed them and send them to battle. When I tried, the cheapest of these blobs cost $200, so the registration fee is about $600... Other gamers are bolder (or they enter before the price spikes) because Axie claims 250,000 active players and 90,000 ETH (or more than 300 million US dollars) is traded on its internal market.
"Everyone is watching the success of Axie Infinity and saying,'Wow, this is definitely the future,'" Decentraland's Hamilton said. He added that this is only part of the future of the meta universe, because "gaming is not everything", but for many people, this seems to be a real attraction. Hamilton said that although events (such as the "To the Moon" music festival) provide peak traffic, playing and making crypto games has always been "the most popular thing on Decentraland."This brings us back to the sandbox, back to the Pandapops live broadcast, and making your own game ecosystem. The sandbox is betting on the game. Their "Game Maker" console allows you to create games (even complex mission games) from scratch, such as the game with aquariums and taverns being developed by Pandapops: your character will start the game without memory, You will unlock the memories of the journey and you need to find a way to escape the maze. In the end, you will rescue a once evil ogre from the hands of the ogre."We want to make sure that when we open a virtual world, it doesn't look like an empty mall," Borget said. Therefore, they incentivize artists in two ways: 1) Remuneration for creating artwork, 2) If the artist can sell their artwork to someone on the Sandbox market, they will receive 100% of the money. "This is incredible. In the years I have been engaged in art creation, since 2007, I have never seen such a work," said Voxel Bunny, who sold a witch tower for 3,150 sand. According to today's The price is approximately US$2,300.Then there is the Game Maker Fund. According to Borget, 450 artists and 54 studios have received funding to create sandbox games. One of these 54 studios is Sand Rush, co-founded by Christopher Weller, whose alias is Necrobombicon. "I entered this industry as an artist," Weller said. "I learned that Sandbox is willing to pay its artists in cryptocurrency."
At first he thought he would knock out some assets himself, and then he met other like-minded artists on Sandbox Discord. They created a game studio called Sand Rush and produced exquisite games like Jungle Rush, described as "an ancient place of magic, mystery and legend" and "ancient technology lurking in the shadows." He has found that the sandbox is profitable. Sand Rush collaborated to create the "Temple of Truth", which is a mysterious structure and sold for 100,000 sand, or about $100,000 at the current price.What's in this sandbox market? At the time of writing, you can buy "pool party cool guys" for $42, an ATV for $787, a tree house for $840, and a "crazy pool" for $525 (it's totally unclear how crazy the pool is). For those with more budgets, you might want to consider the $3,150 "ancient magic statue" (neither ancient nor magic), the $10,429 "robot incubator" or the $5,214 "summer rock metal band".
Although most of the funds surrounding the crypto ecosystem are difficult to understand or deal with, here is an example of how the rising wave of crypto prices directly helped artists. This may have a domino effect. First, Voxel Bunny created Witch Tower and sold it for $2,300, and then it might be the buyer—the game creator—using it in a monetization task. Now, players of this game will earn cryptocurrency when they try to solve tasks, thus completing a virtuous circle.Enter Darth VaderDecentraland or sandbox? At least for now, the various meta-universe projects seem to believe that each other needs cooperation rather than competition. "I don't think this is a winner-takes-all situation," said Hamilton of Decentraland, who thinks that just like Twitter, Facebook, Snapchat and Tik-Tok there are spaces — each plays a different role — there will be space for metaverse Multiple platforms in. Sandbox’s Borget said that “everyone has different powers”, Decentraland is more suitable for events, Crypto Voxels is simpler and more accessible, and Sandbox is more suitable for games.But in the end, of course, we have a problem that hangs over all of this. This is what I call the Darth Vader scenario.
A strange coincidence is that on the same day I was talking to many of these crypto meta-universe advocates, I happened to visit a friend who wanted to show off his new "Oculus", which is a virtual reality headset. It is made by Facebook. This is the gateway to the horizon, Zuckerberg's meta-universe plan.I put on VR goggles, completed a quick tutorial, and took a breath when I found myself standing on top of a skyscraper.A virtual city enveloped me. The blue sky, the car that honked the horn, the plane overhead-everything looked real. Maybe not very realistic, but real enough that when I peeked from the edge of a skyscraper, my stomach shrank sharply when I saw the ground in the distance. I have no fear of heights. My brain knows, in fact, yes, of course, I am safely in my friend's living room. It does not matter. When I walked out from the edge of the skyscraper and looked down at the 100 stories below me, I was both scared and excited."Jump!" My friend urged me.
"no way.""do it!"
I hesitated, but what left me at a loss was my friend's young son mocking my cowardice behind his back. Finally, I jumped off the edge of the board...Of course, I landed safely on the carpet in the living room.Then I took a virtual roller coaster, played a virtual shooting game, played a Star Wars virtual reality (VR) game, and Darth Vader. I want to buy an Oculus. Games and VR technology are not particularly new, but it's one thing to understand it abstractly, and it's another thing to see it with your own eyes and feel it in your bones.
I thought of Pandapop's humble aquarium again, with creepy fishes and the splash effects she painstakingly added. I thought of her simple game, you need to escape the maze and kill the ogre. Indeed, Pandapops can own that aquarium, profit from her game and claim to have a legal sense of empowerment. (Of course, blockchain games may become more complex over time, especially when creators are incentivized to make more, which is also true.)But will ordinary players care?Just look at the internet. For decades, whether we know it or not, most of us have chosen the speed and convenience of large-scale technology centralization. Even if this damages our privacy or agency rights, we still enjoy our stored passwords, automatic login, and the fun of using Google, Apple, Facebook, etc. Make our digital life smoother.We prefer a concentrated Darth Vader to a scattered labyrinth. Time will tell whether our choices in the meta-universe are different.Coin Circle News reported that Charles Gasparino, a member of the Fox Business panel, revealed in a tweet yesterday that Ripple's legal team stated that they did not consider reaching a settlement with the U.S. Securities and Exchange Commission (SEC). They must decisively prove that SEC Chairman Gary Gensler pursued the case in order to select winners and losers in the encryption business, which is not conducive to innovation.As of press time, according to Huobi global data:

The ruling Democratic Party and the opposition party have agreed to take legislative action against crypto. Currency taxation, there is no reason to delay the implementation of the law. Earlier news, South Korean parliament representatives proposed in 2020 to impose a 20% capital gains tax and a 2% local income tax on cryptocurrency transactions with an annual income of more than 2.5 million won (approximately US$2,100). The law was originally scheduled to take effect in October 2021, but has since been revised and its implementation has been postponed until January 1, 2022.On September 18, the government is paying close attention to the cryptocurrency circulating in foreign markets, because the agency responsible for checking financial fraud is paying attention to a company called Hyper Fund. According to sources, Hyper Fund, a subsidiary of Hyper Tech Group, has recently received attention. Hyper Tech Group said that the establishment of Hyper Fund is to provide a decentralized financial infrastructure. Hyper Fund was announced in mid-2020. According to the company’s website, it is led by Ryan Xu, but Hyper Fund with a multi-level marketing (MLM) model has been attracting investors with higher returns, and such issuance is a common practice under the Ponzi scheme, which first aroused the authorities Attention. According to sources, complaints against such funds have begun to emerge in multiple states.
Biquan News reported that on September 18, the Governor of the People’s Bank of China, Yi Gang, said in the opening speech of the Sino-German "Fintech and Global Payments Panorama-Exploring Xinjiang Region" video conference, saying that in recent years, financial technology has been growing rapidly in China. develop. Technologies such as artificial intelligence, big data, cloud storage, and blockchain continue to promote the digital transformation of financial institutions. The application of products and tools is becoming more abundant, and the efficiency and inclusiveness of financial services have been greatly improved. The development of financial technology has also effectively contributed to the rural revitalization strategy. The use of satellite remote sensing, electronic fence, blockchain and other technologies can dynamically monitor the production and operation of agricultural products such as agriculture, forestry, animal husbandry and fishery, promote the in-depth integration of capital flow, logistics, and business flow, improve the availability of financing for the agricultural industry and upstream and downstream enterprises, and help the agricultural industry modernization. In response to the lack of farmers’ “digital footprint” and other issues, digital means can also be used to improve the rural credit information system, which will help expand credit coverage.At present, Tencent continues to promote the establishment of technical standards for landmark agricultural products brand traceability, brand marketing and protection, brand image design and other sections, and makes full use of big data, Internet of Things, blockchain and other technologies to fully assist landmark agricultural products brands in areas with weak digitalization across the country. Accelerate growth.
On September 15, the Maritime-Shutu Lingang Blockchain Technology Research Institute, co-built by Shanghai Maritime University and Shanghai Conflux Blockchain Research Institute, was established. It is reported that after the institute has landed in Lingang, it plans to carry out research and application in the following four aspects: Relying on the openness of Lingang and the tree map public chain, the exploration and application of "the construction of offshore RMB international payment channels based on the tree map public chain" will be carried out. Practice; combined with its own exploration and technological advantages, lead or participate in the construction of the port trade and financial blockchain standard system; create shipping blockchain technical standards and shape a new shipping ecology; develop a technological ecology and fully empower the industry.Coin Circle News reported that Glassnode data shows that the Realized Price of BTC has just reached a record high of US$21,025.87. It is reported that the "realized price" refers to the "realized market value" of the token divided by the current supply, and the "realized market value" is the market value calculated by adding up the market price of the token when it moves on the chain for the last time.
According to the latest industry research by the evaluation website CryptoHead, due to the surge of cryptocurrency ATMs and the growing interest of the state's population in digital assets, California has become the "most cryptocurrency-ready" jurisdiction in the United States. In the encryption readiness index, California beat New Jersey (5.44 points), Texas (5.28 points), Florida (5.03 points) and New York (4.29 points) with 5.72 points (out of 10 points). The state's total score is also 2.54 points higher than the national average.Cryptocurrency trader and YouTube influencer Lark Davis stated that Ethereum is expected to rise by 190% to reach a five-figure price. Davis told its YouTube subscribers that based on key fundamental factors, the second-largest crypto asset by market value is preparing to appreciate above $10,000. He believes that one of the reasons why the price of Ethereum will more than double is due to the decline in its exchange supply. According to Davis, the supply on exchanges has shown a strong downward trend over the past year, as holders have either locked their ETH in a decentralized finance (DeFi) protocol or used their ETH to buy NFTs. With the normal operation of the supply mechanism, it is only a matter of time before the ethereum supply crisis eventually pushes up prices severely.
Coin Circle News reported that Charles Gasparino, a member of the Fox Business panel, shared information received from sources close to Ripple Labs executives. Allegedly, the US Securities and Exchange Commission's XRP case harmed Ripple's domestic business in the United States, but its business is still booming overseas, further proof that the SEC's encryption enforcement agenda is forcing innovation to occur outside the United States.Statistics from CoinATMRadar show that up to now, the number of Bitcoin ATMs deployed globally has reached 27,670. Distributed in 73 countries or regions, including 24,290 units in the United States, 1904 units in Canada, and 205 units in El Salvador. Each of the remaining countries or regions is less than 200.Coincircle.com reported that the four largest listed Bitcoin miners in North America, Marathon Digital Holdings, HUT 8 Mining, Riot Blockchain, Inc, and HIVE Blockchain Technologies, have an average year-to-date return rate of 140%, while the return rate of Bitcoin is 49%. For those looking for indirect bitcoin exposure or value investment opportunities in the open market, holding equity in North American bitcoin miners is an option.Although Ethereum L2 provides many benefits, such as low gas fees, almost instant transaction confirmation, and inheriting the security of Ethereum L1, there has not been a good catalyst to promote the adoption of L2 until the first on Arbitrum The launch of ArbiNYAN, a major revenue farm, has pushed the TVL (total value of locked positions) of Arbitrum, an L2 network, from USD 238 million to over USD 2.5 billion in less than 5 days.
Although it is still in the early stages, it has fully proved the huge demand for Ethereum L2. Of course, this also raises a question: how can investors gain exposure to this trend? Let's explore some of these methods.Nothing in this article constitutes investment or financial advice. Please do your own research before making any decision.
Investors do not have to bet directly on the success of a single application or L2 network. Instead, investors can configure the L2 infrastructure layer in their portfolio and choose those tools that power L2 to gain exposure.This strategy may be suitable for investors who want to avoid choosing who will be the winner in the L2 ecosystem, but still want to gain exposure to assets that will benefit from L2 growth. In addition, due to the network effects of these infrastructures and the huge barriers to entry faced by other competitive services, many infrastructure agreements are in a monopoly position and the competition they face is limited.
The DeFi protocol requires safe and trust-minimized oracle price feeds to realize contract pricing and timely liquidation activities. For example, almost all major DeFi protocols deployed on the Optimistic L2 network, including Synthetix, Aave, Curve, SushiSwap, Dopex, and other protocols, have integrated Chainlink (LINK) oracles into their feed prices to achieve timely settlement And other activities.The protocol not only needs to access data off-chain, but also data on-chain.
