❶ Musk again warns against Bitcoin, Ethereum and calls for "maximizing" Dogecoin upgrade

Tesla billionaire Elon Elon Musk has repeatedly tweeted in recent months in favor of dogecoin over Bitcoin, Ethereum and other cryptocurrencies, and now he’s backing the meme-based crypto again currency.

Musk, the self-proclaimed “technologist at Tesla,” was voted CEO of Dogecoin in a tongue-in-cheek Twitter poll. He warned of the limitations of Bitcoin and Ethereum, calling them "slow" and "costly."

Musk responded to Dogecoin investor and YouTuber Matt Wallace on Twitter: “In my opinion, using exchanges as a de facto secondary There are many layers to it, so it’s beneficial to maximize the base layer transaction rate and minimize transaction costs.” Musk added: “(Bitcoin and Ethereum) are pursuing a multi-layered transaction system, but the underlying transaction speed It's slow and transaction costs are high."

Bitcoin supporters hope that the Bitcoin network, through its payments-focused Lightning network and a recent upgrade called "taproot," Ethereum, the second-largest cryptocurrency after Bitcoin, is in the midst of a long-awaited upgrade, although it may still be several years away from completion.

In reply to Wallace’s tweet, Musk stated that “an update to Dogecoin is coming” and “will perfectly position Dogecoin to become one of the most commonly used currencies in the world. ." It is worth noting that in May of this year, Musk proposed an upgrade to the Dogecoin blockchain network, claiming that "Dogecoin needs to become the currency of the earth" and "easily" defeat Bitcoin.

Dogecoin’s price has soared this year, initially riding on January’s meme stock craze, but then forming a meme community led by Musk, who predicts that Dogecoin will Coin will eventually compete with the likes of Bitcoin and Ethereum.

Musk has alienated many in the Bitcoin community with his mercurial stance on Bitcoin and cryptocurrencies on Twitter, having previously said that all of his Dogecoin-related comments should not be viewed as Seriously, but he has since doubled down on his support for Dogecoin — calling on developers to support it and even promising to send “Dogecoin to the moon” through his rocket company, SpaceX.

Tesla continues to hold more than $1 billion worth of Bitcoin it purchased earlier this year, but Musk also said he personally holds Dogecoin.

❷ Twitter and Musk reached a US$44 billion acquisition agreement, what does this mean?

It means that Musk’s company will acquire Twitter. Twitter will become their company. The two companies are like grasshoppers on a rope.

❸ Understand the NFT that Musk is talking about in one article | As many as 23 NFT application scenarios

What is NFT

NFT, the full name is Non-Fungible Token , Chinese is a non-fungible token. It is inseparable, irreplaceable and unique. The fungible tokens (FT) corresponding to it can be substituted for each other. For example, you own an ETH and I own an ETH. The two ETHs are essentially the same and there is no difference. In time, we will exchange the two ETHs for each other. Changing it has no impact or difference. Then, non-fungible tokens (NFTs) are like marking fungible tokens, making them unique.

Origin of NFT

Perhaps many people have only recently noticed NFT, but in fact it has been sprouting since 2012. In 2012, a person named Yoni Assia published a blog post titled bitcoin 2.X (aka Colored Bitcoin) – initial specs. The article discussed colored coins and said that colored coins were part of the genesis transaction. They are therefore unique and can be identified from regular Bitcoin transactions. Later, another author, Meni Rosenfeld, wrote an article titled Overview of Colored Coins to continue to explore its value.

Counterparty was born in 2014. It is a peer-to-peer financial platform and a distributed open source Internet protocol built on the Bitcoin blockchain. The corresponding token is XCP.

In 2015, the first game based on blockchain technology was born, Spells of Genesis. Its game developers issued game assets to the blockchain through Counterparty. The game funds development through the issuance of a token called Bitcrystals (BCY), which is also used as currency in the game.

In 2016, Counterparty cooperated with the popular card game Force of Will and also released its own cards on the Counterparty platform. Force of Will game is the top selling playing card in North AmericaThe game is as popular as Pokemon, Yu-Gi-Oh, and Magic: The Gathering.

Someone released rare pepes (RARE) as an asset on Counterparty, a meme with the following frog characteristics.

What is a meme?

The meme originated from a tweet. At that time, liquidity mining was booming, and various imitation disk projects emerged one after another. So Jordan Lyall, the developer of Consensys, mocked these imitation disk projects on Twitter:

What is unexpected is that someone actually created one. With the meme token project, there are also community members who volunteer to build products, hoping to make it a Defi project. As a result, Degenerator has developed from a virtual project into an NFT decentralized platform that supports mining.

Since then, many meme-like projects have appeared on the market, using the same method to obtain user funds in the form of airdrops. So everyone is accustomed to calling this kind of project a meme project. In fact, memes are also tokens.

The meme token is currently priced at $2,655.

Peperium was born in 2017. It is billed as a decentralized meme market and trading card game (TCG) where anyone can create memes and store them permanently on IPFS and Ethereum. The token is RARE, which is used to create memes and for listing fees.

Then Cryptopunk was founded, created by two creative technologists who realized that they could create a unique character native to the Ethereum blockchain, an NFT project.

Subsequently, CryptoKitties, which also became popular in October 2017, appeared. CryptoKitties is a virtual game based on the blockchain that allows players to adopt, feed, and even trade these virtual cats. At the same time, the application of NFT to games has also been promoted to the mainstream market.

A virtual cat like this could sell for $800,000

CryptoKitties was launched in October 2017 by a Vancouver-based company called Axiom Zen. When they released the Alpha version during the ETH Waterloo Hackathon (the largest hackathon in the global Ethereum ecosystem), the team has been working on the project for several months. There were over 400 developers participating in the hackathon, so it was the perfect place and time to introduce the game. The CryptoKitties team won first place in a hackathon competition and the game quickly went viral.

The rise of CryptoKitties coincided with the 2017 bull market, so it was unstoppable. People are buying, breeding and trading virtual cats like crazy. This has led many to see the potential of non-fungible tokens. Axiom Zen subsequently spun out a company called Dapper Labs, which raised $15 million in funding from top investors including a16z and Google Ventures. After witnessing the frenzied action in the CryptoKitties community and Dapper Labs receiving investment from top investors, people are starting to realize the true power of NFTs.

From 2018 to 2019, the NFT ecosystem achieved large-scale growth.

Outlook for NFTs

Sports, games, and entertainment are always exposed to new technologies before other industries, and NFT is no exception. NBA shots, cryptoketties, CryptoKitties games, and art collections have allowed NFT to have successful applications and generate huge profits. According to "I Know Blockchain", it is predicted that NFT will continue to go out of the circle. The above 23 possible application scenarios of NFT can give us confidence. I also hope that this information can give people who want to create more possibilities on NFT more thinking and make more interesting applications.

❹ The virtual currency "Dogecoin" supported by Musk's article, does virtual currency have a future?

I think virtual currency has a future, because many countries have strict regulations on virtual currency. They are all very supportive, and the development of blockchain must be supported by virtual currency.

In fact, many people do not recognize virtual currencies. Indeed, there are many countries in the world that have clearly stated their attitude that they do not support virtual currencies. However, the hype about virtual currencies is still very serious nowadays. of. The price of Bitcoin has already seen huge fluctuations, and now the focus is on Dogecoin.

1. Virtual currency is the basis of blockchain technology

When it comes to blockchain technology, everyone is actually familiar with it. Blockchain technology has been recognized by many institutions, and many countries believe that blockchain technology Technology will become the key to future development and can effectively promote economic development. As the basis of blockchain technology, virtual currency will definitely be favored by more institutions in the future.

Blockchain technology will be supported by more countries in the future. Since blockchain technology can be recognized by more institutions, I think virtual currencies can also be accepted. Virtual currencies have temporarily experienced huge price fluctuations. In the long term, I think the hype for virtual currencies still exists in the market.

❺ Four major highlights in the blockchain field in 2022｜Interface Prophet⑯

There is a core proposition about the "Impossible Triangle" in the blockchain field, namely security sex, performance and decentralization. This proposition is the foundation of the evolution of blockchain technology. Whether it is Bitcoin, Ethereum, or the vigorously developed alliance chain, it is essentially a trade-off between the above three elements.

As Ethereum’s core position among blockchain developers is determined, performance has gradually become a bottleneck for its development. Therefore, in the foreseeable 2022, improvements in performance and efficiency will be a long-term and critical issues.

Based on the Ethereum ecosystem, to improve performance within the limits of the "Impossible Triangle", the current path has been clear. The first one is the Layer 1 level, that is, other public chains share the burden of Ethereum. Data pressure.

One of the major trends in 2021 is the increased use of Layer 1Plus, the space is currently dominated by Solana, Avalanche, Terra, and Binance Smart Chain, each with a growing ecosystem worth over $10 billion.

The second type is Layer 2, which is based on the Ethereum main network, but transfers settlement to the second layer network to improve efficiency. This is what Ethereum is working on, Layer 2 is often called rollups because they "aggregate" or bundle transactions together and execute them in a new environment before sending updated transaction data back to Ethereum.

As for the most critical data verification link of the blockchain, Layer2 currently has two technical solutions, one is called "Optimistic rollups" and the other is called "ZK Rollups". Both technical routes have teams developing corresponding networks and have ecological support, such as Arbitrum, which chooses "Optimistic rollups", and dYdX, which chooses "ZK Rollups".

Between Layer1 and Layer2, there is another solution called "side chain", which is partially compatible with the Ethereum main network, but does not belong to Layer2. They are specially used to deal with the excess of Ethereum. capacity, rather than competing with Ethereum as a whole, and hosting Ethereum applications in a complementary manner.

Starting with DeFi, which currently has the most active users, according to statistics from DeFi Lama, the amount of DeFi locked on Ethereum has exceeded 100 billion US dollars, and other public chains such as BSC, Solana, and Avalanche have also Attracting nearly US$49 billion in funds, it has become a very active financial scene.

Although the data of many public chains is quite large, different chains are like data islands, and assets on different chains cannot be freely exchanged. In addition, many emerging public chains are not as developed as Ethereum and lack many foundations. Facilities such as stablecoins, NFT games, and more.

Therefore, assets on other chains need to be introduced into one's own public chain through cross-chain. Among the currently commonly used cross-chain methods, in addition to cross-chain currency withdrawals in centralized institutions such as exchange wallets , the most common ones are various decentralized cross-chain asset bridges.

For cross-chain bridges, the most important issue is how to reach consensus, which is largely related to the security of investors’ assets under custody. For now, the security of centralized exchanges Cross-chain bridges are the most convenient type of cross-chain bridge for users. However, cross-chain bridges in centralized exchanges have the problem of single points of failure. In addition, current cross-chain bridges are gradually moving towards non-custodialization. Development is to further protect the security of users’ assets.

The full name of DAO is “Decentralized Autonomous Organization", that is, "decentralized autonomous organization", which is an organizational form that attempts to get rid of the traditional bureaucracy management model and use blockchain technology to complete autonomous operations.

Go Centralized Autonomous Organizations (DAOs) are able to leverage blockchain-based governance to achieve global coordination of individuals. DAOs can be used for many purposes, including managing the operations and capital of blockchain projects (MakerDAO), managing investment capital (The LAO), Manage the use of game assets (YGG DAO), coordinate cultural groups (Friends With Benefits) or coordinate the purchase of assets (Constitution DAO).

The number of DAOs included in the deep website has reached 187, and the total assets under management exceed 12 billion U.S. dollars, covering more than 1.6 million members. Although this is not a huge figure in the field of blockchain, institutions including Sequoia Capital are beginning to pay attention to this new term.

The market value of cryptocurrency officially exceeded US$2 trillion in 2021, and is currently at US$2.5 trillion, up 175% from the beginning of the year. With the explosive growth of market value, financing in the encryption field has also risen rapidly. According to statistics, in 2021 The number of publicly disclosed primary market financings in the crypto industry in 2018 was 1,529, totaling approximately US$32.6 billion, a year-on-year growth of an exaggerated 814.2%.

However, equity financing in the crypto field is different from other fields. Under the "VIE" structure, the main exit channel for traditional VCs is for companies to log into the secondary market for IPO. However, the blockchain field has its own new financing method ICO (banned in China). The key difference of this decentralized financing method is The reason is that users can participate in the growth of the community at an earlier stage. Under the traditional venture capital model, only after landing in the secondary market can ordinary investors have the opportunity to share the dividends of corporate growth.

And in In the field of encryption, first of all, the concept of "company" has been weakened. Due to the existence of "Web3" and "DAO", communities and organizations are more mentioned. Users naturally have a sense of distrust towards centralized platforms.< br />
The most popular project in the crypto community in the past two weeks is called "OpenDao", which is a project imitating the leading NFT trading platform "OpenSea". The reason why this project is so popular comes from crypto players' interest in "OpenDao" "OpenSea" is dissatisfied. It has recently been reported that "OpenSea" is undergoing a new round of financing and is preparing for an IPO. However, NFT enthusiasts do not want "OpenSea" to become a monopoly platform like the current Internet giants, so "OpenDao" fought out The concept of centralization and issuing airdrops to all “OpenSea” users.

And at the end of 2021, there was a debate about "Web3" in the encryption community, including Tesla Chairman Elon Musk and former Twitter executive Jack Dorsey pointing the contradiction during the debate Venture capital institutions in crypto finance believe that VCs have gained too much profit.

In 2021, an investment institution in the form of "DAO" also emerged. This kind of organization includes investors who are very influential in the community and are deeply involved in the technology field. They incubate The project performance even exceeds the results of some traditional VCs.

❻ Blockchain news on July 22: Musk holds Bitcoin, Ethereum and Dogecoin

1. Tesla CEO Elon Musk The Word It was said at the meeting that it made sense to support something that would improve the quality of the information we use to manage the economy.

5. Ethereum developers have been working hard to solve problems with the code and clients on the test network to prepare for the next major network upgrade-the London upgrade. July 21, Ethereum OpenEthereum lead developer Tim Beiko has released a "London Testnet Review" report detailing the latest developments in the testing phase of the upcoming Ethereum upgrade. According to the report, OpenEthereum clients noticed on July 21 that their nodes were Ropsten testnetStopped running. After investigation, the problem is not with this client, but with the go-ethereum protocol and the Geth client, which checks the sender balance of the EIP-1559 transaction. It is reported that some clients rejected the block at the time, while others accepted the block and continued processing: "Specifically, OpenEthereum and Besu rejected the transaction/block, while Nethermind, go-ethereum and Erigon accepted them." The issue was later fixed by adding new assertions to the validity of EIP-1559 transactions, and testing continues. It is reported that the test was first activated on the Ropsten test network on June 24; earlier this month, the Rinkeby test network also launched the final testing phase.

6. Tesla CEO Musk said that modern nuclear power plants are safe and supports the use of nuclear energy to generate electricity to mine Bitcoin.

7. The Reserve Bank of India (RBI) is working on a "phased rollout" of India's central bank digital currency (CBDC) — a digital rupee, possible in the future, T Rabi Shankar, deputy governor of the Reserve Bank of India, said on Thursday. Conduct a pilot. The Reserve Bank of India defines CBDC as a digital form of sovereign currency that can be converted into cash or sovereign-backed deposits. The Reserve Bank of India has taken several deliberations on the scope and legal framework of the proposed CBDC, which is likely to co-exist with cash and digital forms of payments. The time for India’s CBDC is approaching. The Reserve Bank of India has carefully assessed the risks and the RBI's efforts are that as we move forward, India's CBDC can reaffirm its leadership in the world's payment systems. The RBI has taken a closer look at several aspects of launching a universal CBDC, including: what it can be used for; the technology underpinning it (distributed or centralized ledger); the basis for verification (token or account-based); and whether it will be used only by Is it issued by the central bank or by commercial banks? There are also several enabling legal frameworks that need to be considered before launching a CBDC. Importantly, these include amendments to Sections 24, 25 and 26 of the RBI Act, as well as provisions of the Coinage Act, 2011, the Foreign Exchange Management Act and the Information Technology Act. The RBI has been exploring the pros and cons of issuing an Indian sovereign CBDC for a long time. The RBI looked at the purpose-specific CBDCs proposed by different central banks around the world for the wholesale and retail sectors. The launch of a population-scale universal CBDC is being considered, and the Reserve Bank of India is working on a phased introduction strategy and looking at use cases with little disruption to the Indian banking and monetary system. Shankar added that cryptocurrencies like Bitcoin do not meet the RBI’s definition of currency and that one reason why central banks around the world are trying to use CBDC is that they want to minimize the risks cryptocurrencies pose to the fiat economy.

She is a 73-year-old "Internet celebrity", an inspirational idol in the eyes of many women, and the author of the best-selling book "My Life".

❽ Musk once again spoke out for Dogecoin: The currency holdings are too concentrated. What is the difference between Dogecoin and Bitcoin?

Many people may not know what Dogecoin is. , what we call Dogecoin (DOGE) was jointly created by American programmers Jackson Palmer and Billy Markus on December 8, 2013. Recently, Dogecoin has become famous both inside and outside the industry due to its skyrocketing price. A small currency, after 7 years, has not declined but prospered. Compared with other currencies, it has already returned to zero. The contrast is really huge, which makes many people find it incredible. Also, the second difference between Dogecoin (DOGE) and Bitcoin is the transaction confirmation time. Satoshi Nakamoto set the Bitcoin transaction confirmation time to ten minutes, which is more conducive to improving the security of large asset transfers. Dogecoin has different uses, it is mainly used as a tipping currency, so Dogecoin needs faster transaction confirmation time, so the founder of Dogecoin set its transaction confirmation time to one minute. No matter what, these virtual currencies are all big bubbles, and we still have to stay away from them.

❾ Musk holds Bitcoin, Ethereum, and Dogecoin. Is Musk a trendsetter in the currency circle?

SpaceX owns Bitcoin, Elon Musk and Nic Carter believe that BTC is becoming more environmentally friendly

Supporters of Dogecoin (DOGE) and Bitcoin (BTC) good friend Elon Musk first revealed on July 21 that his aerospace company SpaceX owns an unknown amount of Bitcoin.

"I do own Bitcoin; Tesla owns Bitcoin; SpaceX owns Bitcoin," he said.

Musk was speaking at “The ? Word,” a virtual event dedicated to Bitcoin, alongside Twitter CEO Jack Dorsey and Ark Invest CEO Cathie Wood, the volatile The tech billionaire hints that Tesla is about to accept cryptocurrencies again as the percentage of renewable energy used for mining is increasing.

Tesla’s $1.5 billion foray into Bitcoin earlier this year triggered a surge in Bitcoin prices. However, Tesla suspended the use of Bitcoin as a payment method in May due to environmental concerns, which appeared to drive down the price of Bitcoin, which has plunged about 40% in the past two months.

Now China Coal Power’s Hashrate Is Declining After Mining Ban, MalaysiaSkoda appears to be warming up to digital gold again. Musk has said Tesla may re-enter the market after he conducts more "due diligence" on mining sustainability and confirms it is backed by 50% or more renewable energy.

One wonders what due diligence this requires and why he didn’t do it before his $1.5 billion Tesla BTC purchase.

Musk also revealed for the first time that he holds Ethereum (ETH) and unsurprisingly reiterated his support for the meme-inspired Dogecoin.

"I personally do own some Ethereum and certainly Dogecoin," he said.

Daily Dogecoin trading volume surges to nearly $1B in Q2

Speaking of Musk’s favorite cryptocurrency, Dogecoin trading volume surged in Q2 2021 It has grown more than 13 times, approaching $1 billion per day.

Dogecoin trading volume surged 1,250% between April and June, with an average of $995 million in DOGE changing hands every day during the quarter, according to data compiled by Coinbase and reported by .

By comparison, Dogecoin’s average daily trading volume in the first quarter of 2021 was $74 million.

While these numbers are sure to create hype among the eagle-eyed Dogecoin community, the subject of the top dogecoin can be a sensitive one for Coinbase.

A Coinbase user has filed a class-action lawsuit seeking $5 million in damages over allegedly misleading Dogecoin activity.

Plaintiff David Suski said he was tricked into trading $100 in Dogecoin to enter a $1.2 million sweepstakes on Coinbase, according to court documents. The lawsuit alleges that Coinbase failed to communicate that a person could enter the sweepstakes without purchasing $100 of Dogecoin.

Ethereum must innovate beyond DeFi’s degraded DApps: Vitalik Buterin

Vitalik Buterin, co-founder and lead developer of Ethereum, urges the Ethereum community to work on decentralized finance or Innovate beyond the confines of DeFi.

During his July 21 keynote address at the Ethereum Community Conference in Paris, Buterin described non-financial utilities as "the most interesting part of the universal blockchain vision."

The 27-year-old outlined several non-financial applications for Ethereum, including decentralized social media, identity verification and attestation, and traceable funding of public goods.

The Ethereum co-founderThe founder has had a busy week, and after speaking at the Ethereum conference, he also appeared in the living rooms of Ashton Kutcher and Mila Kunis. Of course, he wasn't trespassing, but was there as part of a promotion for Kunis' NFT project, "Stoner Cats."

Buterin gave a lengthy explanation of Ethereum’s basic components and clarified how the smart contract protocol differs from “single-purpose” chains like Bitcoin.

Grayscale sets sights on institutional DeFi funds

While Buterin is looking beyond the decentralized boundaries of finance, digital asset management giant Grayscale is looking to gain exposure in the space.

On July 19, Grayscale CEO Michael Sonnenshein announced a new investment vehicle targeting DeFi assets.

During an interview with CNBC’s Squawk Box, the CEO chimed in to announce Grayscale’s plans for a DeFi fund and index. The Grayscale CEO detailed the purpose of the new product, saying the fund will provide its institutional clients with exposure to DeFi assets such as Uniswap and Aave.

The same week, Sonnenshein said he believed the United States was only "a few points mature" with its first Bitcoin exchange-traded fund (ETF).

After multiple rejections of BTC ETFs in the past and 13 ETF applications under consideration, Sonnenshein is undeterred and said the company is "100% committed" to bringing its Bitcoin product to market when the conditions are right. Grayscale Bitcoin Trust Converts to ETF.

U.S. lawmakers don’t want Olympic athletes to use digital yuan at 2022 Games
