A. How are blockchain exchanges ranked?

Blockchain exchanges
You are referring to platform transactions. Domestic ones are illegal, and international ones are mostly scams. For establishment, look for the ones that are well-known. There is a special introduction on the blockchain network. Remember it must be legal, otherwise you won’t be able to withdraw money and it will be useless.

B. Blockchain platform, which one is good?

First of all, you must choose based on your needs. You must also pay attention to the team’s strength and effectiveness, and understand the blockchain aspects of BakerChain. well done. You can consult first.

C. In the United States, a battle to defend the encryption industry is starting

In recent weeks, a red alert has suddenly sounded for the US encryption industry.

From strengthening the supervision of the DeFi market to launching tax policies for the entire encryption industry, the U.S. encryption industry has been strongly attacked by regulatory authorities, and a battle to defend the encryption industry has begun.

1. Why does the U.S. encryption industry oppose taxation provisions?

On July 28, a draft infrastructure bill aimed at improving U.S. transportation, electricity, and water resources included a provision to tax the U.S. crypto industry at the last minute of the Senate debate. According to estimates by the Joint Committee on Taxation of the U.S. Congress, the federal government could raise $28 billion within ten years by taxing the crypto industry.

However, due to the bill’s strict information reporting system and the broad definition of taxable objects in the legislative language, it has triggered a huge sense of crisis among people in the American industry.

According to the official legislative text of the bill, "any person responsible for regularly providing any services to realize the transfer of digital assets on behalf of others" is defined as a "broker", and the broker is required to comply with the 1099 regulations of the IRS. -B tax return reports information on cryptocurrency transactions over $10,000 and pays taxes. The IRS's 1099-B return shows that the information reporting requirements include personal information such as the taxpayer's name, detailed address, phone number, and customer's name, as well as a detailed description of the transactions related to receipts, sales, profits and losses.

The bill’s rather broad definition of “broker” makes industry insiders worry that miners, node operators, wallet developers and other institutions will also be involved. Previously, centralized exchanges such as Coinbase had filed tax returns as required by the IRS.

"One of the things that impressed me about working in Washington is the importance of the right to petition. Democracy is about more than voting." Jerry Brito, executive director of crypto policy advocacy nonprofit CoinCenter, July 30 He was one of the first to call for action on Twitter.

Specifically, the objections of people in the U.S. encryption industry mainly focus on the following points:

First, miners and nodesParties such as operators and developers do not have the ability to collect "customer" information and should be explicitly excluded from the definition of brokers;

Second, the bill may force almost all companies related to cryptocurrency to It is necessary to strengthen the monitoring of personal information of daily users, and the implementation of cumbersome monitoring systems may cause these companies to stop services in the United States;

The longer-term worry is that strict information reporting requirements will increase the number of encryption companies in the United States. The legal complexities of undertaking project development or validating transactions have resulted in industry innovation organizations moving offshore.

2. Lobbying to "leverage" Washington

As a result, U.S. encryption industry leaders and U.S. congressmen have launched multiple intensive back-and-forth discussions regarding the specific wording of this bill. Lobbying to protect the competitiveness of the U.S. crypto industry.

Long before the bill’s formal legislative text is released, the draft’s wording of the taxation provisions could be even worse. The draft’s definition of a broker, in addition to descriptions such as “providing digital asset transfer services”, is also expanded to clearly “include any decentralized exchange or peer-to-peer market.” Lobby groups such as the Digital Chamber of Commerce issued warnings in interviews with the media.

After receiving objections from some industry insiders, on August 2, the wording "including decentralized exchanges or peer-to-peer markets" was deleted from the official legislative text. This was achieved through lobbying efforts by the crypto industry. The first round of progress.

However, the definition of taxable objects in the official legislative text is broad and vague, and the sense of crisis in the U.S. encryption industry is still strong.

According to Jerry Brito’s Twitter timeline, policy advocacy organizations such as CoinCenter have been contacting and lobbying members of the Senate who may support the crypto industry’s stance since July 29.

On August 4, encryption people successfully contacted the Senate, and three senators, Ron Wyden, Cynthia Lummis, and Pat Toomey, submitted an amendment consistent with the industry’s position. The Wyden-Lummis-Toomey amendment explicitly exempts three categories of people: validators of the distributed ledger network (i.e., miners, stakers, node operators, etc.), hardware and software wallet sellers, and protocol developers.

Industry insiders do not accept it. They believe that the legislative intention does not have legal effect and require a clear exemption in the legal text.

The Twitter encryption community was quickly "swiped" - KOLs called on people in the encryption circle to call members of Congress to put pressure on them. The digital rights activist group Fight for the Future attached a channel and rhetoric for automated calls to lawmakers in a post called "Red Alert," which was circulated for several days. Coinbase also makes one-click emails to members of Congresspage. In addition, industry insiders called for donations to policy lobbying organizations such as CoinCenter, and some crypto companies responded.

There was not much time left for the U.S. encryption industry before the Senate vote. Intensive lobbying was carried out within a week, which benefited from the attention and layout of lobbying by leading U.S. encryption companies in recent years.

According to the Washington Post, there are currently nearly 60 registered lobbyists for U.S. cryptocurrency companies, up from just one five years ago. Data from the Center for Responsive Politics, a nonpartisan organization that tracks policy lobbying spending, shows that U.S. cryptocurrency companies will also double their spending on lobbying this year compared to last year.

In terms of the establishment of lobbying groups, in April 2021, Coinbase jointly established a new encryption policy lobbying organization "Crypto Innovation Committee" with the asset management company Fidelity, the payment company Square, and the investment company Paradigm. According to the New York Times, Coinbase has spent more than $700,000 on government lobbying since 2015.

The lobbying power of the U.S. crypto industry has been relatively dispersed before, and conflicts of interest between Coinbase and Binance have always existed. According to the New York Times, Coinbase had been a member of the local American industry association Blockchain Association before 2020, but in the summer of 2020, after rival exchange Binance was included in the Blockchain Association, Coinbase withdrew from the organization. The spearhead ignited by this bipartisan infrastructure bill has gathered a rare and unified lobbying force in the U.S. encryption industry.

Portman’s round of modifications triggered a bigger “explosion” in the encryption circle. Industry insiders accuse that the amendment does not exempt protocol developers from paying taxes, and only exempts PoW miners, ignoring the verifiers of other consensus mechanism networks. In essence, the U.S. Congress is deciding the winner or loser of different types of technologies.

As soon as this news came out, Musk, who had been silent on the matter for many days, also made a statement: "Now is not the time to pick technical winners or losers in cryptocurrency technology. There is no crisis that forces hasty legislation."

p>

August 7th and 8th are the voting days for the Senate. As an alternative version of the bipartisan infrastructure bill, Amendment 2137 proposed by Pornman and others passed the Senate 69-28. Despite this, Portman and others were fiercely attacked by Wyden, Lummis and other factions.

According to the special decision-making process of the U.S. Senate, the remaining amendments, including the Wyden-Lummis-Toomey Amendment supported by the encryption community, require the consent of all 100 senators before they can be passed.

After 30 hours of limited debate, the two parties finally reached a compromise. But because Senator RichardShelby was opposed by one person, and the compromise version ultimately failed to pass. Sinema-Warner-Portman Substitute Amendment No. 2137 was submitted to the House of Representatives for consideration.

However, some people in the US encryption community are not discouraged, saying that a brand new amendment can be formulated from scratch in the House of Representatives to address all concerns.

3. DeFi supervision is also strengthening

In addition to taxation policies targeting the entire cryptocurrency industry, U.S. regulatory authorities have also recently significantly increased their emphasis on the DeFi field. DeFi supervision was discussed in public occasions.

First, in early June this year, U.S. Commodity Futures Trading Commission Commissioner Dan Berkovitz suddenly attacked DeFi derivatives in a forum speech, saying that the unlicensed DeFi derivatives market is a bad idea and does not comply with the " The relevant requirements of the Commodity Exchange Act. At the same time, he pointed out that DeFi derivatives projects lack market guarantees and customer protection, and impose regulatory obligations, restrictions and costs on other market participants, which will form unfair competition.

According to the Financial Times, the US SEC and CFTC communicated with representatives of leading DeFi projects such as Uniswap and dydx through online meetings at the end of June to explore the review of the DeFi market.

On August 3, U.S. SEC Chairman Gary Gensler attended the Aspen Security Forum and stated that any stock token or crypto token that provides underlying security exposure is subject to securities laws, and any offering of securities DeFi projects that provide nature-based token services are all within the scope of SEC supervision. Although no specific regulatory policy has yet been introduced, the SEC’s statement has made it clear that it will strengthen supervision of the DeFi industry.

Recently, regulatory authorities in many states in the United States issued bans on the crypto lending platform BlockFi. The reason is that regulatory authorities regard interest-bearing cryptocurrency savings products as investment contracts and are therefore subject to the supervision of the Securities Act, although BlockFi is Centralized lending platforms, but since similar fixed-rate savings products also exist in the DeFi market, CoinDesk columnist Preston Byrne believes that these bans may be a precursor to similar actions against DeFi.

If the U.S. regulatory authorities further advance the legislative process along these lines, many DEX projects and derivatives projects will have certain risks and will need to be registered in accordance with the requirements of the U.S. Commodity Exchange Act, which may result in It will cause many developers to be prosecuted and hinder the further advancement of DeFi innovation.

Under frequent pressure from regulation, many DeFi project parties have taken countermeasures. For example, in July this year, the decentralized aggregation trading platformShapeShift announced the closure of the corporate entity and transformation into a decentralized autonomous organization to avoid friction with regulators.

Also in mid-July, Uniswap Labs excluded 129 synthetic stocks and derivative tokens from the front end of the Uniswap trading page, citing the "changing regulatory environment" to avoid potential regulatory risks.

In addition to making business adjustments and adopting defensive strategies, multiple DeFi protocols are also trying to promote the operation of DeFi policy lobbying organizations in an attempt to promote the introduction of more friendly regulatory policies.

One of the representatives is the DeFi Education Fund, which Uniswap is mainly responsible for funding. The organization, formerly known as the DeFi Political Defense Fund, received 1 million UNI funding through Uniswap community voting in June to engage in legal analysis, policy advocacy, In terms of information transmission and other aspects of work, the chief legal officers of many leading DeFi projects such as Uniswap, Aave, Compound, etc. also participate in the specific operations of the organization, thereby promoting policy formulation that can represent the interests and positions of millions of DeFi users.

Recently, YFI founder Andre Cronje and others also launched a proposal to fund $1 million for the DeFi legal advocacy organization LeXpunK_DAO, and hinted that Curve and SushiSwap will also participate in it to promote a series of constructive activities in the DeFi industry. For example, launching landmark position papers, providing legal defense for DeFi developers against regulatory lawsuits, and proposing "safe harbor" legislation to legalize key aspects of DeFi.

4. Summary

Generally speaking, the regulatory trend of the encryption industry in the United States has become increasingly obvious. However, in the view of most KOLs in the encryption industry, many regulatory departments and lawmakers in the United States are Without being familiar with the operating mechanism of the encryption market, rashly formulating policies that are difficult to operate and highly harmful to the industry will not be conducive to the development of the encryption industry, nor is it in line with the goals of policy formulation.

D. See how the world’s top ten stock exchanges play with blockchain

Institutions have begun to experiment with this new technology.
DTCC is a U.S. clearinghouse that processes quadrillions of dollars in transactions each year, and Visa, the global credit card processing network, is just some of the best-known non-bank pilot projects. That said, some financial sectors are certainly more active than others.
Major stock and commodity exchanges are arguably the most active institutions involved in blockchain experiments. For example, Nasdaq, a major U.S. stock exchange provider, even released its own blockchain trading model last fall. The program, called Linq, can trade and track private company stocks. Nasdaq positions it as blockchain technology expansion major stockearly-stage experiments in the scope of ticket trading and even new asset classes.
Blockchain_stock exchanges
Although there are more differences in subtle areas, the world's 10 major stock and commodity exchanges have currently expressed interest in blockchain technology. In this article, we will give you a detailed introduction:
1. Australian Securities Exchange (ASX)
When it comes to the application of blockchain technology, the ASX is definitely one of them One of the most ambitious companies, it invested more than $10 million in startup Digital Asset Holdings in the industry in January as part of its research and development drive.
At the same time as the investment, the ASX also revealed that it will not only conduct technology trials, but also establish a new post-trade settlement system, which will be developed by Digital Asset through the use of a distributed ledger structure.
However, since January this year, updates on the project’s progress on the ASX may have been overshadowed by controversy. In March, Australian news media began speculating that, although the ASX had reaffirmed its support for the trial, the blockchain project might also be thrown into doubt following the premature resignation of the agency’s CEO Elmer Funke Kupper. Voice,.
2. Chicago Mercantile Exchange Group
CME Group is one of the founders of the "Post-Trade Distributed Ledger Working Group" and has currently carried out very active actions in the industry through its investment arm CME Ventures .
CME Group is unique among its peers. It has always pursued a diversified investment strategy across industries and has successively invested in distributed accounting startup Ripple, blockchain investment group Digital Currency Group and Digital Asset Holdings. Beyond that, however, CME Group has yet to speak publicly about its conduct in technology and the larger industry.
3.Deutsche B�0�2rse
Deutsche B�0�2rse, the operator of Germany's Frankfurt stock exchange, is another player on this list, and it also participated in the Digital Asset Holdings’ $60 million financing.
However, unlike its co-investor ASX, Deutsche Börse has been less vocal about its support for the technology.
In an interview in February this year, Deutsche B�0�2rse said it is conducting a proof-of-concept related to the technology, although it has not released any findings or test results.
4. Dubai Multi Commodity Trading Center
In the Middle East, blockchain-related activities are relatively scarce, and this situation continued until the recent opening of the Global Blockchain Council. The 32-member Global Blockchain Council is a group of startups, financial firms and tech giants that oversees technology applications and their impact.
Built on the basis of these members, Du Multi Commodities Center is a special economic zone and commodity circulation center responsible for overseeing the trading of precious metals and other tangible commodities.
DMCC announced in February that it was engaging in a technology trial with Bitcoin startup BitOasis to explore how blockchain technology could improve its personnel onboarding process.
5. Japan Exchange Group (JPX)
Japan Exchange Group is a relatively active stock market operator in Asia. It announced its interest in the industry in February and has officially formed an alliance with IBM. Become a user of Blockchain-as-a-Service (BaaS).
At the time, reports stated that Japan Exchange Group was embarking on a proof of concept to study the role of blockchain technology in creating a new trading system for low-liquid assets, with the final results to be released through a report later this year announced.
Earlier this month, Japan Exchange Group also announced that it is working with the Nomura Research Institute (NRI) to conduct trials to study how the technology can be applied to the securities market.
6. Korea Exchange
Korea Exchange, South Korea’s only stock exchange and one of the new entrants to this list, announced in February that it would seek to launch a counter via blockchain technology trading platform.
In statements to local news outlets, Korea Exchange said it hopes the technology will help reduce costs. Details about the trial and the company's involvement in the group were not released.
7. London Stock Exchange (LSE)
The London Stock Exchange is one of the founding institutions of the “Post-Trade Distributed Ledger Working Group” and when it comes to experiments on blockchain technology, the LSE It is one of the most dynamic but also the most low-key institutions.
The London Stock Exchange is one of the first groups to follow in the footsteps of startup R3, and it is the first to say that large financial firms will look to use collaborative models to conduct blockchain testing, beyond R3’s frameshelf.
It was also from that time that some large financial companies began to participate in private proof-of-concepts and operations in certain areas of the capital market involving various parties.
In addition, like Kouvola Innovation and Japan Exchange Group, the London Stock Exchange is also one of the initial customers of IBM's Blockchain-as-a-Service (BaaS).
8. Nasdaq
When it comes to testing blockchain technology, Nasdaq is probably the most proactive organization. U.S. stock market operator Nasdaq first launched Linq, a private equity trading platform, in 2015, thus becoming the first financial institution to conduct a blockchain proof-of-concept. The platform is currently still in the testing phase.
In addition, Nasdaq has also reached a cooperation with blockchain solution provider Chain and allows its internal experts to speak openly about blockchain technology.
In 2016, Nasdaq continued this momentum. For example, it previously revealed that it is working with Estonia’s Nasdaq OMX Tallinn Stock Exchange on a trial to use blockchain technology to reduce various obstacles to shareholder voting.
9. New York Stock Exchange (NYSE)
The New York Stock Exchange was one of the first companies to take an interest in the industry. In 2015, the NYSE issued two important announcements. The statements are all related to Bitcoin.
In January 2015, NYSE invested in the Bitcoin service company Coinbase as part of its Series C financing. At the time, NYSE Chairman Jeffrey Sprecher said the investment showed confidence in the widespread use of digital currencies by millennials, whom he described as having a more progressive view of value exchange.
The NYSE will continue to launch a Bitcoin price index in May, which will also become a competitor to CoinDesk’s Bitcoin Price Index (BPI), which is plotted with transaction data from the Coinbase trading platform.
10.TMX Group
TMX Group, the operator of the Toronto Stock Exchange, has never expressed a clear opinion on blockchain technology.
However, with the hiring of Anthony Di Iorio (one of the co-founders of Ethereum) as the agency’s first chief digital technology officer, TMX also publicly expressed its interest in the blockchain for the first time in March this year. Interest in chain technology. The next-generation network has become one of the most important blockchain applications in the public eye following its product launch in March.
Nonetheless, TMX Group has stated that it is in the early stages of generating a blockchain strategy and that it may soon conduct technical tests

E. What is blockchain in a layman's terms

Question 1: Blockchain isWhat, can you explain the principle of 10-point blockchain in plain language: decentralized distributed accounting system
The core of blockchain technology is that all currently participating nodes jointly maintain transactions and databases. It enables transactions to be based on cryptographic principles rather than trust, allowing any agreed parties to directly conduct payment transactions without the participation of a third party.
?
Technically speaking, a block is a data structure that records transactions, reflecting the flow of funds for a transaction. The blocks of transactions that have been reached in the system are connected together to form a main chain, and all nodes participating in the calculation record the main chain or part of the main chain. A block contains the following three parts: transaction information, hash hash formed by the previous block, and random number. Transaction information is the task data carried by the block, specifically including the private keys of both parties to the transaction, the number of transactions, the digital signature of electronic currency, etc.; the hash formed by the previous block is used to connect the blocks to realize the past The order of transactions; random numbers are the core of transaction completion. All miner nodes compete to calculate the answer to the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for update, thus completing a transaction.
1.1 What is Blockchain
Blockchain (BlockChain) refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. This technical solution mainly allows any number of nodes participating in the system to associate and generate a series of data blocks (blocks) using cryptographic methods. Each data block contains all the information exchange data of the system within a certain period of time, and generates The data fingerprint is used to verify the validity of its information and chain to the next database block.
?
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. Behind all systems there is a database, which is a big ledger. Then who will keep this ledger becomes very important. At present, it is whoever owns the system who keeps the accounts. Each bank’s account books are kept by each bank, and Alipay’s account books are kept by Alibaba. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are new transaction data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write the recorded content to the ledger, and Send the contents of the ledger during this period to all other people in the system for backup. In this way, everyone in the system has a complete ledger. Therefore, this data becomes very safe. A tamperer needs to modify more than half of the system node data at the same time to truly tamper with the data. Such tampering would be extremely costly, making it nearly impossible. For example, Bitcoin has been running for more than 7 years. Countless hackers around the world have tried to attack Bitcoin, but so far there have been no transaction errors. It can be considered that the Bitcoin blockchain has been proven to be a safe and reliable system.
?
1.2 Why is there blockchain innovation?
Human beings need to communicate during their activities, and communication is based on information. In the past, information circulation was not convenient enough to satisfy market participants. There is a demand for information, so intermediaries and centers are born. This centralized system has problems such as high cost, low efficiency, value dispersion, "information islands" and insecure data storage. However, due to technical and environmental factors, this system continued to operate for many years until the emergence of the Internet. The starting point of the first generation of the Internet is the TCP/IP protocol, which is an open code that implements a unified format for peer-to-peer transmission of information by all nodes on the network, and brings the basic values ​​of freedom and equality required by a global unified market into programmed, protocol-based, and reliably Execution. The Internet eliminates low-value, high-cost intermediate chains and achieves low-cost and high-efficiency global information transmission in a decentralized manner.
?
However, the first generation of the Internet did not solve the problem of information credibility. Activities that can be decentralized on the Internet must be activities that do not require credit endorsement, and activities that require credit guarantee must be activities involving centralized third-party intermediaries. Therefore, Internet technology that cannot establish global credit has encountered great obstacles in its progress - people cannot participate in any value exchange activities on the Internet in a decentralized manner. To realize value exchange, people still need third-party intermediaries based on credit (such as banks, clearing agencies, exchanges). The global centralized credit system still has problems such as high operating costs, low efficiency, and vulnerability to attacks and damage. For example, each country's legal currency has different credit values ​​and incompatible clearing systems, which adds a lot of cost to global trade.
?
Therefore, what the second generation Internet must break through is: how to establish global credit in a decentralized manner? Let...>>

Question 2: What is blockchain? What does it mean in layman’s terms? What is China’s attitude towards blockchain? What can blockchain do? Blockchain, a great technology that accompanied the birth of Bitcoin, is currently being used in the financial field to significantly reduce transaction costs and improve efficiency, which is enough to excite Wall Street. However, this is just the tip of the iceberg. Its potential applications are very broad and will subvert every aspect of our lives in the future.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. One of the most basic characteristics of Bitcoin is decentralization. In recent months, financial giants have gradually begun to pay attention to Bitcoin's technology and used it in non-monetary fields, such as stock trading, election voting, etc. (1) Art Industry
Artists can use blockchain technology to declare ownership, issue numberable, 100% edition works, and can target any type of artwork.digital form. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.
(2), Real estate industry
Use blockchain technology to solve various problems faced by everyone involved in real estate, including the naming process, land registration, agency intermediaries, etc.
(3), Insurance Industry
The financial industry has always been the most sensitive to advanced technology. Traditional banking and securities industry giants have been involved in the booming blockchain venture capital investment since 2014, with total global investment reaching US$1 billion within two years.
(4) P2P wallet
Personal assets can be traded through this P2P wallet in the future without going through any central institution, such as Bitcoin.
Most blockchains are in their infancy, mainly overseas. There are very few good domestic blockchain projects, so it is not recommended for any non-professionals to invest in blockchain projects. If you are very interested in blockchain technology and have a technical or financial background, it is recommended that you consider starting a business in this area. In terms of the blockchain protocol system, the lowest layer is the underlying technology of the blockchain, including the technical protocols of the blockchain, as well as some platform routing and basic algorithms; in the middle layer, some application interfaces and some credentials must be solved Issuance and verification, including some industry platform services, big data analysis, etc. This is a very rough classification, and there should be more detailed classifications; the top ones are some applications of blockchain, including finance Some applications and some applications in other aspects, the Internet of Things and so on.
Introduction to Bubi Blockchain
Bubi Blockchain has been focusing on the research and development and innovation of blockchain technology and products since its establishment. It has a number of core technologies and has achieved substantial results in many aspects. Radical innovation has resulted in a number of core technological achievements, such as: mathematically provable distributed consensus technology, fast large-scale ledger access technology, multi-chain general ledger technology that supports business expansion, and interconnection technology between heterogeneous blockchains. wait. On April 25, "Gege Points" introduced the concept of blockchain into the points system, jointly opened it up with multiple parties, issued and redeemed points, and promoted the circulation of points. Each cooperative institution can jointly participate in transaction verification, ledger storage, and real-time settlement; the third-party payment platform of the enterprise points issuer makes the entry and exit of points more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, points, credit and other fields. Bubi has been committed to building an open value circulation network with decentralized trust as the core, allowing digital assets to flow freely.
A simple understanding of blockchain is a technology at the bottom of Bitcoin, which is also a peer-to-peer electronic cash system that can realize peer-to-peer value delivery. We should distinguish between Bitcoin, Bitcoin blockchain, blockchain and blockchain. Blockchain technology and other concepts. In countries with more developed finances in the past, financial block technology has a long history., the legislation of digital currencies and blockchain networks is also very important. With the advent of the financial era, large financial institutions are studying blockchain technology. They have their own teams and conceptual technologies. Slowly, banks in various regions are also participating in digital currency discussions. The application and support of this technology are not only that. The influence of blockchain on enterprises is also huge. For larger domestic enterprises, Bubi Blockchain is also used in various equity, supply chain, points and other fields. Major domestic financial institutions and enterprises have taken a fancy to the new industry. value, they have developed their own blockchain platforms, and blockchain has instantly become a new innovative industry in China. In terms of overseas internationalization, the United States has already obtained 15 blockchain patents at the end of last year compared to China. Blockchain financial applications are entering a new stage in an all-round way. Various applications will become more and more in-depth, and related changes will also become more and more profound. It has attracted more and more attention and will form a huge new trend... >>

Question 3: What is blockchain technology? What exactly is blockchain? What is blockchain? 1. Data blockchain is an important concept in the Bitcoin financial system. It records transaction record data on the entire Bitcoin network, and these data are shared by all Bitcoin nodes. Through the data block, we can query each transaction record. A look at the history of Bitcoin transactions. 2. Example: There are three persons A, B, and C. All funds of A and B are kept by C. And every financial transaction must be recorded by C. Now assume that A and B each have 1 million in custody of C. Then: A spends 80,000 yuan to B, then C's account book record will subtract 80,000 yuan from A's name, and add 80,000 yuan to B's name. If B transfers 50,000 yuan to A, C will add 50,000 yuan to A's name and subtract 50,000 yuan to B's name in the account book. A spends 50,000 yuan to B, then C's account book record will subtract 50,000 yuan from A's name, and add 50,000 yuan to B's name. 3. The role of the data blockchain is similar to that of C’s account record book. It records the user’s ownership of Bitcoin and the records of all users’ Bitcoin transactions. It’s just that this “account record book” is recorded by the mining software of every Bitcoin miner on the network. If a Bitcoin transaction is confirmed by the data blockchain, the relevant information will be recorded in the data blockchain. Bitcoin’s “account record book” is called the data blockchain. All data blockchains on the network form Bitcoin’s distributed network database system. 4. The essence of data blockchain technology is a decentralized and distributed structure of data storage, transmission and certification methods. It uses data blocks to replace the current Internet's dependence on central servers, so that all data changes or transaction items are recorded. On a cloud system, the self-certification of data during data transmission is theoretically realized. In a far-reaching sense, this transcends the traditional and conventional information verification paradigm that relies on a center and reduces the cost of establishing global "credit." This peer-to-peer verification will produce a "basic protocol", a new form of distributed artificial intelligence that willEstablish new interfaces and shared interfaces for human brain intelligence and machine intelligence.

Question 4: What is blockchain: This explanation of blockchain is more understandable. Blockchain refers to a technology that collectively maintains a reliable database through decentralization and trustlessness. plan.
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Then who will keep this ledger becomes very important. Currently, whoever owns the system keeps the accounts. Tencent keeps the accounts of WeChat, and Alibaba keeps the accounts of Taobao. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are any data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write his recorded content into the ledger, and record this Within a period of time, the contents of the ledger are sent to all other people in the system for backup. In this way, everyone in the system has a complete ledger. In this way, we call it blockchain technology.
Blockchain technology has become the darling of the financial community in China and has become a hot topic. Domestic Puyin Group has launched Puyin, a tea-based digital currency.

Question 5: Explain in an easy-to-understand manner what blockchain is. Blockchain can be understood as a database system in a sense. The development of blockchain can be divided into 1.0 and 2.0
1.0 is represented by Bitcoin, and its main application is virtual currency or digital currency application. The blockchain at this time can only be used for simple digital currency transactions.
2.0 is represented by the now popular ethereum (Ethereum) and the upcoming hyperledger. The blockchain at this stage can not only meet the corresponding digital currency transactions, but also use smart contracts to customize currency or asset transactions. If we use the database analogy, the emergence of smart contracts can be understood as allowing users to define functions or stored procedures in the database and call and execute them.
Different from traditional databases, the blockchain introduces consensus mechanism, incentive mechanism, p2p (network), hash and other specific elements, making it open, decentralized and non-tamperable. characteristic.

Question 6: What is blockchain? Can anyone explain it in simple terms? Blockchain is the underlying technology of Bitcoin. It is like a ledger that records all transactions. It is decentralized. What is decentralization? For example, when you buy something on Taobao, you place an order and pay in Alipay. Alipay will not transfer the money to the seller until you receive the goods. Alipay is the third party in that center. without it it isDecentralization is like buying things offline. If you pay with one hand and receive the goods with the other hand, there is no third party.
The blockchain itself is a series of cryptographically related data blocks generated.
Look carefully to see if it looks like a ledger. The pieces one by one are blocks, and connected together they are the blockchain.
Many companies are developing this technology, including ours, and its prospects are incredible. For details, you can go to our official website and hope to adopt it, thank you

Question 7: What is blockchain technology? What is blockchain? How to explain the concept of blockchain? People in each industry have different understandings, and relevant explanations are gradually emerging due to more and more real-life applications. With the popularization of this blockchain technology, the related results are getting bigger and bigger. If we want to understand this technology, we must have an in-depth understanding of reality.
In the past six months, the concept of blockchain has gradually become popular in China, and a blockchain whirlwind has taken off in the financial circle. Blockchain has attracted the attention and favor of more and more people in the industry due to its unique technical advantages. Blockchain technology, which is decentralized (or multi-centered), highly transparent, cannot be tampered with, and has no single point of failure, is entering the field of vision of financial institutions and enterprises. It has at least been used in digital currency, payment exchange, registration and settlement, Digital assets, traceability and anti-counterfeiting, supply chain, Internet of Things and many other fields have moved from theoretical discussions to practical applications.
"Blockchain" was first introduced with "Bitcoin" released in early 2009. Blockchain has become the basic protocol and technical application for the launch, recording, and circulation of Bitcoin. Although Bitcoin has been controversial since its inception and cannot even be regarded as a "currency" by governments and monetary authorities, the blockchain technology used in Bitcoin has been recognized by governments, including governments and monetary authorities. extensive attention.
Why has blockchain become a rapidly heating up hot technology and topic?
The most important of these may be that the launch of Bitcoin based on blockchain technology has opened up a new relationship with traditional society ( The exploration and attempt of new technologies and rule systems such as Internet user identity verification, wealth confirmation, transaction records, notarization and verification, which have little connection with offline) and are completely applied to the online world (online), provide people with the opportunity to adapt to the Internet society. Development provides alternative paths and unlimited imagination.
Judging from its application in Bitcoin, blockchain is a set of new network blocks (BLOCK, also called communities) formed by combining encryption technology with the Internet. Bitcoin configuration, netizen identity verification, and Bitcoin (value) confirmation formed by mining, Bitcoin transaction records, and extended encryption of Bitcoin cross-block flow (value transfer) (added block and transaction time identification, etc. Factors) registration and verification, including blockchain connection (Blockchain), full encryption, mutual authentication Internet protocol rules and accounting (Ledger) system. Precisely because Bitcoin is not a substitute for offline legal currency, but is issued and managed by non-legal currency authorities, mainly imitating the model of gold, and is completely new and decentralized protected and supported by basic Internet protocols and strict encryption technology. Internet currency (virtual currency) has thus formed a new set of currency rules and systems that are different from and not subject to real social laws, and can be bought, sold or exchanged with legal currency. It has been more than 8 years since Bitcoin was launched. There has been no record of funds or user information being stolen. Its security has been verified, and its efficiency and cost of fund settlement also have obvious advantages. This has made people's confidence in the blockchain technology used in Bitcoin continue to increase, and people have become more and more aware that although blockchain is a technology and protocol pioneered and applied by Bitcoin, the blockchain Chain is not the same as Bitcoin, and its application is by no means limited to Bitcoin. The application of blockchain can be decentralized or centralized; it can be a public chain model or a private chain model. Therefore, after Bitcoin, blockchain technology is also constantly developing and innovating, and constantly exploring new application fields, especially in the financial field.
The reason why blockchain is valued highly by more and more people is because the development and widespread application of the Internet have caused more and more economic exchanges and transaction activities to be conducted online, and the online world (or online world) society) is rapidly expanding, enriching and active, and online transactions must solve the efficiency and security protection issues of the parties' identity verification, value verification, transaction records, inspection and verification, etc., and require strict intermediaries and agreements (rules or constitutions). In this regard, traditional thinking and customary practices are to follow the development trajectory of the transfer of offline transactions to online and push the common rules and practices of the real (offline) society to the online (network) society. However, in practice, it is increasingly It is difficult to adapt to the needs of online transactions.
For example, for the identity verification of the parties, the natural choice is to use the information on the identity documents protected by the laws of various countries as the basis, and then add account or transaction passwords, as well as facial recognition, iris, fingerprints and other biometrics to conduct online transactions. Verification, but this method first makes the citizen identity information in the cross-border interconnected online world subject to the administrative jurisdiction of real society... >>

Question 8: Easy to understand Explain clearly what is blockchain. The English name of blockchain is Blockchain. Block literally means block, block, and chain means chain, chain. Therefore, together they are translated into blockchain.
1. Use cryptography technology to encrypt and decrypt so that records cannot be tampered with. Common blockchain encryption methods include hash algorithm, RSA algorithm, elliptic curve algorithm, etc.;
2. The huge amount of calculation needs to be supported by a reasonable reward mechanism. Because every transaction must be recorded, so far, Bitcoin’s blockchainThere are already more than 60 G. Every new transaction requires confirmation of the information related to the trading account to ensure that the transaction is valid. The huge amount of calculation requires a computer with powerful computing power to complete.
In order to encourage the participation of powerful computing power, Bitcoin provides two rewards: one is to issue a certain number of Bitcoins to these computers every day; instead, all transfer fees are awarded to these computers. (The technical term for these computers is "mining machines", and the people who hold the mining machines are called "miners".)
Biying China is working hard on the digitization of assets and has launched the digital currency crowdfunding platform Biying China.

Question 9: What is the so-called "blockchain"? Blockchain itself is a tool called decentralization and trustlessness. For example, when you graduate from university, the current practice is to have a certificate recognized and issued by an authoritative agency as your certificate. This setting is more troublesome, because this is a piece of paper, and paper can be forged, so there will be various gaps. The issuing authority is also a person, and there will be various gaps in the middle. As long as it is related to people, whoever There are various possibilities related to media. The blockchain provides a great opportunity. As soon as you graduate, you will have a record on the blockchain. No one can change this record. This thing exists objectively. You, as a physical existence , and then as a data existence, the blockchain was born. In this case, anyone who wants to check where you graduated can easily solve the problem. This is similar to the big data often involved in social networking (WeChat) and payment platforms (Alipay, Yibao).

Question 10: What does blockchain mean? Regarding blockchain, I think you have already seen the concept on the Internet. Let me explain it based on my understanding!
First, let’s talk about its characteristics: 1. Openness and transparency 2. Decentralization 3. Anonymity 4. Information cannot be tampered with, eliminated 5. No trust cost
Blockchain is like a public ledger , everyone has the right to record and read, and everyone will jointly supervise to ensure its accuracy, and the recorded content will be permanently saved, and can only be added but not deleted! However, as the number of blocks continues to increase, costs will increase and efficiency will decrease. (I’m not sure whether technology can be used to make up for this. I hope someone who understands technology can point it out.)
Blockchain is divided into public chain, private chain, and alliance chain. Public chain: accessible to everyone, everyone has read and write permissions, completely open, transparent and decentralized. Private chain: Open to individuals or institutions, in which the owner of the private chain can set various permissions to make it partially centralized. Alliance chain: Open to specific organizations or groups, it is also "partially decentralized". According to the ledger at the beginning, members can view and transact, but cannot record and confirm bills, or require permission from the alliance. (The latter two do not have cost and efficiency issues)
Regarding blockchain, countries have begun to recruit talents in this area. For this, you can search online for "Central Bank Recruiting Digital Currency R&D Personnel". In addition, you can increase your understanding of blockchain by understanding its existing applications. What we usually refer to generally refers to public chains. Currently, those used abroad include Bitcoin, Ethereum and other domestic blockchains. Chain
1. Open and transparent: Every piece of data is verified by everyone and can be viewed by everyone at any time.
2. Decentralization: For example, when we shop on Taobao, we conduct transactions through the intermediary Taobao, and blockchain allows both supply and demand parties to directly contact each other for direct transactions through blockchain technology.
3. Anonymity: No personal privacy information is required to complete transactions on the blockchain, only your unique alphanumeric signature is required.
4. Information cannot be tampered with or deleted: Once the data has been verified and recorded, no one has the authority to modify it, let alone delete it!
5. No trust cost: The trust crisis in reality will not appear in the blockchain. Transactions in the blockchain do not require you to trust the other party. Only when both of you have enough "digital assets" to trade can it be carried out, and Under the supervision of the entire network, transactions will not be broken. If you have no idea about the cost of trust, just think about how many intermediaries there are in your city, or just think about Jack Ma, and you will know how big the cost of trust is.
I am still learning more about blockchain. I am Li Ailin. If you have any questions, you can discuss and learn together!

F. What are the popular blockchain exchanges currently?

The currently popular centralized exchanges include Binance, GATE, and Huobi. GATE is more convenient for deposits and withdrawals. . But decentralized trading is a trend in the future. Currently, the Loopring protocol is doing better in the field of decentralized trading in China.

G. What to do if a U.S. blockchain account is frozen

You need to check the freezing period and location through the bank where you opened your account or the bank’s telephone hotline. Contact the local police as soon as possible and ask them to provide you with the payment that led to your being implicated. If they do, provide the relevant information as requested by local police. Relevant information is generally used to explain why you transferred this fund. Therefore, generally speaking, it includes the order records of your Huobi OTC transactions within a certain period of time (you can log in to your Huobi OTC account and click the order in the upper right corner to export and print), your frozen bank card transactions, etc. In addition, if the police need you to provide personal information of a certain counterparty, please contact OTC customer service and follow the legal procedures provided by customer service.
When the above materials are provided to the police, they will give some feedback based on the different handling methods of the public security systems in various places and the different cases. For example, some will strictly require the case to be solved or withdrawn before it can be unfrozen, some can only freeze the funds involved in the case, and some places can unfreeze it directly. If you take notesFinally, if the police refuse to unfreeze directly, you can ask about the funds involved in the case. If the funds involved are much smaller than the frozen funds, then you can apply to unfreeze the non-involved funds. In a legal sense, if you are really not involved in telecommunications fraud or money laundering, but are only frozen for selling digital assets, then you should be an implicated bona fide victim, and it is recommended to consult a relevant lawyer.
Most judicial freezes are only temporarily frozen to cooperate with police investigations. They will be automatically unfrozen within two or three working days. Don't worry about this, it will be automatically unfrozen when it expires. But you should also pay attention to transferring the money during the period, because it is possible that the case involved has victims in more than one place, so it may be frozen by more than one place, and it may be frozen again in the future. In addition, this 48 or 72 hours does not mean thawing on time, but may be delayed by several hours or even half a day.
