II What is aBey blockchain technology?

Hope it can help you:

What is aBey blockchain technology? An independent research project by two Ph.D.s in Artificial Intelligence from the Department of Computer Science, School of Mathematics and Informatics, Western University of Timisoara, Romania: Ciprian Pungila & Vorel Negru. It adopts constant light blockchain technology and multi-layer programming and expanded blockchain solutions. aBey’s blockchain size has always remained the same, its size is only 50 active blocks. aBey blockchain technology is suitable for using electronic currency to conduct large-volume transactions in e-commerce systems, and is multi-layered, scalable, secure and programmable.

The official white paper claims that aBey is a blockchain solution suitable for large-volume transactions using digital currency in e-commerce systems and capable of multi-layer programming and expansion.
The specific implementation method of aBey blockchain technology:
Use a multi-layered and programmable blockchain method to implement digital currency (for simplicity, we call it "DC"). This approach paves the way for performing various e-commerce purposes such as loan financing, completing refundable and non-refundable transactions, etc. The inherent digital currency design is implemented on the first layer of the blockchain—what we commonly call the base layer (“FL”). Various upper layers are built on top of the foundation to describe various additional functionality related to various business-driven application instances (which we will briefly describe below). All of the above levels are fully programmable and can be easily adapted to suit a variety of different application instances.
Although most digital currencies today store transaction differences in the blockchain, aBey’s approach is more similar to the PascalCoin digital currency. This method uses an encryption structure we call a "Vault". The "Vault" structure saves only the balances of all accounts in the network, rather than a complete list of all completed transactions, and can be reconstructed throughout the blockchain's evolution history. Since Vault allows useless content to be deleted at any time, it can significantly reduce the storage cost of the blockchain. By comparison, at the time of writing, the storage space required to download the Bitcoin database is 70GB (the alarm rate continues to grow and is expected to reach 300GB in 2019), so the storage space used is smaller (e.g., 120GB or 256GB) It is no longer feasible to implement mining operations on ultrabooks or laptops. The size of the aBey blockchain, on the other hand, will always remain the same, with a size of just 50 blocks (at the time of writing, there are over 525,000 blocks in the Bitcoin blockchain).
Vault fully supports digital currency transfers between accounts. In addition, Vault can assign an owner-defined name to each account rather than utilizing a hashing algorithm like today’s cryptocurrencies—this can make accounts easier to remember and names can be exposed to the public.
One of the important features of Vault that helps prevent excessive daily fees on the blockchain (especially those related to transaction history) is that Vault can save such by creating a secure copy of the state of the blockchain. status and at the same time reduce the size of the blockchain itself. Since no transaction history is required and all accounts can save their direct balances, the blockchain information has the characteristic of being partially erasable. All storable blockchain states can be considered landmarks for that blockchain.
Secure data sharing:
Through blockchain structureBy design, the blockchain may contain encrypted metadata for every transaction sent to the network. This metadata can only be decrypted by the recipient of the transaction. This is accomplished by including the sender's public key in transactions sent to the network, and having the recipient of the transaction use the public key to decrypt the metadata. Since the transaction recipient holds the private key for decryption, the data decryption process can only be performed by the transaction recipient. From an encryption method perspective, while Bitcoin is limited to using elliptic curve cryptography, blockchain metadata can be encrypted using any other encryption mechanism. Not only does this provide complete flexibility in security choices, it does so without any adverse impact on the structure or functionality of the blockchain.
Scalability:
Given that the aBey blockchain supports the creation of historical landmarks by design, the network itself will Very easy to achieve high scalability. This method completely eliminates the need to store transaction history in order to calculate the balance of all accounts, and can directly store all account balances, thereby ensuring that the specific balance information provided by all nodes in the network meets Byzantine consistency requirements.
Security and Proof-of-Work:
According to reference, two-way payment operations are not possible in aBey’s method (in a properly specified scenario, most of today’s mainstream cryptocurrencies are theoretically possible There are two-way payment operations). Each transaction is meant to update the balance of the corresponding account in a relatively simple manner, and there is no special way to remove the transaction from the network's pending transaction queue. For aBey Blockchain, Vault is very important to the mining operation given that all technical/functional layers are built on Vault, which is the infrastructure of our blockchain. Our proposed blockchain model consists of a sequence of blocks, where each block is mined by voluntary nodes in the network using a proof-of-work model. All nodes in the network can independently update their account balances based on transactions (components of blocks) and independently from other nodes. Mining operations will have an impact on the first functional layer. In addition to updating the balance, each node can also update other matters in the blockchain structure that may belong to the upper functional layers. Once an update occurs, a new mining reward block will be created. This mining reward block contains multiple new reward accounts that have been assigned to miners. Miners are the recipients of the above rewards based on proof of work (the current number of reward accounts is 50). Rewards are awarded by assigning the public keys of all such accounts to the reward recipients.
Blockchain technology layer:
aBey’s digital currency model contains a multi-layer structure, of which the first layer represents the implementation of the digital currency itself (see Figure 7 for a graphical explanation). The corresponding levels include:
Level 1→Digital currency (cryptocurrency): currency transfer, mining
Level 2→Refundable transactions and non-refundable transactions:Allows refundable transactions to be completed using a digital justice system
Layer 3 → Affiliates and Commissions: Allows automatic distribution of commissions to affiliates
Layer 4 → Contact Currency: Earns income based on interest by lending currency
Layer 5 → Programmable: reserved for future implementations of Turing-complete programming models to facilitate processing of blockchain data (e.g., smart contracts, etc.) in customized ways
Layer 6 → Custom protocol: reserved for future use
Transaction type:
aBey’s model allows multiple transaction types to be completed at different levels in the blockchain through design. The transaction types in the first layer are as follows:
1→Fund transfer: transfer funds between accounts (1-to-1 transfer)
2→Refundable fund transfer: refundable funds between accounts payment transaction. Use escrow balances in place of regular account balances
3→Key Change: Change the keys that can be used to process an account
4→Recover Account: Recover funds from a lost, invalid account
5→ Set account name: Define the name of the account held by the founder
6→ Sales preparation: mark the account ready for sale
7→ Remove from sales queue: remove the account sales mark and mark the account as unsellable
>Refundable transactions and mediators:
For the vast majority of instances, non-refundable transactions are equivalent to counterpart payment transactions in all blockchain-based digital currency models. But aBey has introduced the concept of refundable transactions into its own digital currency model. In aBey mode, transactions marked with small flags are refundable or non-refundable. In addition, in aBey’s blockchain network, each account contains two types of balances: regular and unchangeable balance (used to mark that the account has been received and can be spent immediately, but cannot be recovered after spending amount) and escrow balance (contains a list of transactions marked as refundable, and the number of minutes for each transaction).
8→Payment dispute: Initiate a payment dispute for the corresponding transaction that has been marked as a refundable transaction, but it can only be initiated by the payer.
9→Refund request: Initiate a refund request for the corresponding transaction that was previously marked as a refundable transaction, but it can only be initiated by the payer.
10→Cancel escrow: Cancel the escrow funds and return the funds to the payer immediately. Can only be initiated by the payee.
11→Release escrow: Release the escrow funds and immediately add the amount to the payee's account balance. Can only be initiated by the payer.
Affiliates and Commissions:
One of the important missing pieces in today’s blockchain-powered fintech is the lack of the ability to reward affiliates for selling specific products or services. aBey Blockchain Layer 3 can solve this problem.
Lending Digital Currency:
Lending Digital Currency is not only a simple and fast way to allow people to borrow fiat currency, but it also keeps crypto assets safe. Given that today's valuable digital currencies are also used for transactions, what makes lending digital currency feasible is not just any type of cryptocurrency that allows borrowers to pledge their savings, but also attractive because it is also a Keep your digital assets in a completely safe or extremely low-risk way. In addition, aBey’s model provides built-in protection through the customer Vault Lending Gateway (VLG) and enables the VLG to act as a buffer between lenders and borrowers.
12→Borrowing funds: The borrower initiates a transaction within the network, announces the intention to borrow funds, and specifies the VLG account for borrowing funds. The transaction is similar to depositing a regular/custodial account balance into the selected VLG account
13 → Return of Collateral: The transaction is initiated by VLG itself. VLG will return the collateral to the borrower in accordance with the risk treatment policy.
14→Loan repayment: The transaction is initiated by the borrower. If VLG accepts loan repayments in the form of digital currencies, borrowers can choose to utilize digital currencies to repay their loans. Under this condition, digital currency funds will be converted into VLG regular account balances.
Programmable Blockchain:
With the metadata payload associated with it, the first layer of the blockchain can be preserved as permissible by executing the syntax-based "Complete Turing Basic Programming Language" , following the original blockchain data processing method, further creating smart contracts between peers in the network. For each payload, encrypted or publicly viewable processing can be implemented and executed in a dedicated virtual environment (similar to a virtual machine). This method effectively protects data security and avoids data corruption and security breaches. The main advantage of this approach is that this layer can create and enforce digital contracts without the need for any blockchain-specific programming. For this layer, we will carefully consider the extension direction of this layer during future upgrades and define the appropriate syntax and semantic environment required to implement the corresponding functions. At the same time, other layers established in the future (Layer 6, Layer 7 and higher) can be used to expand related protocols for more use cases as needed. But its disadvantage is that realizing the above functions will require the blockchain itself to complete the "soft fork" or "hard fork" process.
Experimental results:
aBey is currently implementing relevant experiments and will publish the experimental results on GitHub, the world's largest open source platform.

Ⅲ Can blockchain freeze currency accounts?

Blockchain can freeze currency accounts.

A piece of news titled "The Central Bank Adopts a Series of Cleanup and Censorship Measures to Prevent and Resolve Financial Risks and Moral Hazards" began to circulate on major websites. The article mentioned that "Alipay has currently investigated and closed about 3,000 accounts engaged in virtual currency transactions."

A blockchain investor and currency circle boss said that it is used to trade cryptocurrencies such as Bitcoin. Multiple bank accounts of the currency have been frozen repeatedly. It can take as little as three days and as long as two months.” The direct reason why his account was frozen was thatThe account was used for OTC cryptocurrency trading. High Chong

“I feel that as long as I am caught trading Bitcoin, (bank account) may be frozen, because some of my accounts were frozen after only using them twice, and only one of them was traded. The amount of one BTC is only a few hundred thousand.

According to his reflection, he and many friends around him basically no longer use the OTC trading function of the platform, but instead try their best to conduct transactions among acquaintances. Trading.

And he himself chose to stay on the sidelines because he was not optimistic about the current market. He only kept about 20% (BTC), and the rest was converted into USDT or Qitan Annihilator legal currency.

Most of the frozen accounts at the beginning of the year were suspected of suspicious transactions:

Since the beginning of this reform year, there have been frequent reports in the currency circle that trading accounts have been frozen. News. However, after later understanding, most trading accounts were frozen mainly because the accounts were suspected of suspicious transactions.

On September 13, 2017, the China Internet Finance Association (NIFA) issued the "About Preventing Bitcoin "Reminder on Risks of So-called "Virtual Currencies"", stating that "Bitcoin and other so-called 'virtual currencies' are increasingly becoming tools for illegal and criminal activities such as money laundering, drug trafficking, smuggling, illegal fund-raising, etc. Investors should remain vigilant and should detect clues about illegal and criminal activities." Report the crime immediately. ”

In early January this year, a well-known blockchain website Tieba posted a post about bank cards being frozen. It attracted a large number of onlookers, with nearly 40,000 reads and more than a hundred replies.< /p>

IV Glossary Blockchain

Blockchain is explained as follows:

Blockchain is actually equivalent to a disintermediated database, which is composed of a It is composed of data blocks. Each of its data blocks contains the information of a Bitcoin network transaction, and these are used to verify the validity of its information and generate the next block.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Ledger.

Type

Public Blockchain

Public Block Chains: Any individual or Any group can send transactions, and the transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process.

The public blockchain is the earliest blockchain and the most widely used Blockchain, the virtual digital currencies of all major bitcoins series are based on public blockchains. There is only one blockchain corresponding to this currency in the world.

Industry Blockchain

Industry Block Chains (Consortium Block Chains): Multiple pre-selected nodes are designated within a certain group as bookkeepers, and the generation of each block is jointly decided by all pre-selected nodes (the pre-selected nodes participate in the consensus process);

Other access nodes can participate in transactions, but they are not involved in the accounting process (it is essentially still managed accounting, but it becomes distributed accounting, how many nodes are pre-selected, and how to determine the accounting for each block (or become the main risk point of the blockchain), anyone else can conduct limited queries through the open API of the blockchain.

Private Block Chains

Private Block Chains: Only use the general ledger technology of the blockchain for accounting. It can be a company or an individual. With exclusive write access to the blockchain, this chain is not much different from other distributed storage solutions.

Traditional finance is trying to experiment with private blockchains, while public chain applications such as Bitcoin have been industrialized, and private chain application products are still being explored.

IV What are the practical effects of blockchain technology

The most widely used application of blockchain is still in the field of financial technology, such as digital asset transactions. As an underlying technology, blockchain is the technical implementation method of Bitcoin. The rapid application of blockchain technology also requires virtual currency. In the past, a large-scale economic scenario that required mutual trust and extensive collaboration among many people could only be solved through a centralized approach, which was very inefficient. The emergence of blockchain technology solved this problem and eliminated this center. An important reason why this center can be removed is that virtual currency provides an endogenous economic incentive mechanism for the blockchain, giving people the motivation to join the economic activities transformed by the blockchain. Of course, blockchain will have more extensive and mature applications in more fields in the future. For example, in November last year, the State Grid submitted a patent application titled "About blockchain power transaction control methods and devices." This year, Xi'an The City Wall International Marathon is also the first in the world to use blockchain technology to register athletes’ race data, winning links and other information on the blockchain, using its traceable and non-tamperable technical features to open up information channels between events and effectively Guaranteed the reliability of competition results.

VI How Yibaoquan uses blockchain technology to protect data security

Yibaoquan is the first company in China to use blockchain technology for electronic data solidification and storage, and has been recognized by judicial authorities Electronic data depository and security institution has been committed to the technology research and development and innovative application of blockchain since 2013, innovating the "blockchain + judicial + application" model and creating four major trusted blockchain basic applications and alliance blocks Chain "Security Chain Open Platform".

It is also the 2018 Industrial Internet Pilot Demonstration Project of the Ministry of Industry and Information Technology (the only regional Blockchain selected enterprise), blockchain technology and qualifications are highly recognized by the country.

Ⅶ How to remove the fake and preserve the true in the blockchain

The era of barbaric growth is coming, which is both an opportunity and a challenge for the blockchain.
In recent years, blockchain has gradually developed into a hot topic. Especially in 2018, which has just entered, the concept of "blockchain" has appeared frequently in the business world. So what exactly is blockchain? Why is Liang Shiqiao, an entrepreneur and capitalist, so concerned?
Previously, many people thought that there was an equal relationship between blockchain and Bitcoin, but after in-depth understanding, they discovered , this is a wrong idea. To put it bluntly, blockchain is a distributed ledger, and Bitcoin uses blockchain technology to improve itself.
Blockchain is a decentralized technology, just like a country. In this country, the distribution of data information and rights between people is the same, and there is no falsification of data. It is possible and impossible to lose. The two major advantages of sharing mechanism and value exchange are the power of blockchain.
Is blockchain becoming a new trend after Bitcoin?
As early as 2008, Satoshi Nakamoto published an article titled "Bitcoin: A Peer-to-Peer Electronic Cash System" on the forum. The concept of blockchain was first proposed in the article.
However, there have been constant controversies since the emergence of Bitcoin. Among them, the loudest opponents are Warren Buffett and Robert Shiller.. Buffett, known as the "Stock God", made it clear that Bitcoin "will definitely not have a good outcome in the end." Of course, there are also voices of support. Wall Street tycoon Jamie Dimon believed that Bitcoin was a scam a year ago, but now he has overturned his previous view and believes that blockchain is real. Regardless of the final outcome, the development of Bitcoin has attracted more and more attention in recent years.
In 2013, Bitcoin skyrocketed 100 times from being worthless at the beginning. However, in the next two years, Bitcoin showed a sharp decline again. In 2014, it fell by no less than 70%. In 2015, it fell by more than 20% again. By 2016, Bitcoin entered an upward stage, and by 2017, it was resurrected. This roller coaster development not only brought losses to people, but also attracted more attention to the blockchain.
People love and hate Bitcoin. When Bitcoin becomes popular, as the core foundation and underlying architecture of Bitcoin, blockchain is gradually attracting people's attention. Blockchain is the key to supporting the formation of Bitcoin. The reason why Bitcoin can achieve such results is inseparable from the blockchain. Since every transaction in Bitcoin is recorded in a block-by-block ledger, this ledger is decentralized, and the blockchain serves as the "role" of the Bitcoin ledger. Bitcoin can be said to be the best application of blockchain, bar none.
Some time ago, Xue Manzi acquired this domain name, and in this transaction, Xue Manzi used Bitcoin to complete the transaction. This incident caused quite a stir in the circle. Recently, the frequency of use of Bitcoin in domain name transactions has been increasing, and what caused this phenomenon is the importance that capitalists attach to blockchain.
Previously, blockchain was only used by Bitcoin, but in recent years, as Bitcoin gradually spreads around the world, blockchain has begun to be applied in various projects, such as Ant Financial, JD.com, Internet and Tencent have gradually begun to apply blockchain technology. The authenticity and non-tampering nature of blockchain makes its application in other projects such as public welfare even more convenient. For example, Ant Financial has applied blockchain technology in "Hearing-impaired Children Regain a New Life", Tencent has launched the "Public Welfare Tracing Chain" and so on. By 2017, blockchain has begun to be widely used and has gradually formed a new trend.
The era of barbaric growth is coming, which is both an opportunity and a challenge for the blockchain
There is this sentence in Dickens's "A Tale of Two Cities": "It was the best of times, it was the worst of times, it was wisdom. This is an era of stupidity. People have all kinds of things in front of them, and people have nothing in front of them; people are going straight to heaven, and people are going straight to hell." Just like the blockchain, if you do it well, you will be the pioneer who participates in the changes of the times. Do it poorly and you will perish.
Today, the blockchain is facing such a situation: the rapidly developing society and the emerging enterprises have brought many possibilities to the blockchain, which has attracted more attention and accelerated the development of the blockchain industry. The enterprise application of blockchain may usher in a new era.
BlockchainIt can be roughly divided into three types: private chain, alliance chain and public chain. Each blockchain corresponds to different scenario applications. The most critical difference between these blockchains is the scope of restrictions on the degree of decentralization. Blockchain is also widely used due to its distributed recording of data, data cannot be tampered with, and is open and transparent. Different from the transmission of information on the Internet, the blockchain is the transmission of value, which can be said to be an upgrade of the Internet. Based on this, blockchain is considered to be another central technology that is very likely to cause a disruptive revolution after steam engines, electricity, and the Internet.
But the blockchain is not omnipotent:
Firstly, there is delay in the blockchain. Take transactions in Bitcoin as an example. Its effectiveness is affected by network propagation and takes ten minutes to complete. Be informed and recognized;
Secondly, the blockchain itself does not have the two functions of "modify" and "delete", which makes post-processing very troublesome if errors occur when recording data.
In addition to its own limitations, in the face of the complex enterprise market, blockchain, which has gradually become the new darling of the market, has also led to a series of "accidents" such as "coin speculation" and "pseudo-blockchain". .
In September last year, the country had banned the trading of virtual currencies such as Bitcoin and ICO, but the strong money-making effect has brought the currency speculation boom back to people's attention. First, Xunlei launched Wankecoin (now called LinkToken) in October, then Renren released the blockchain project "Renrenfang" and the token RRcoin, and Kodak launched Kodak Coin. Many companies have entered the blockchain development industry. currency, which makes the phenomenon of "coin speculation" sweep across again.
Currently, there is no shortage of money-making projects on the market. Companies are mixed in the blockchain application market. It is difficult for investors to distinguish the pros and cons of projects, and there are even situations where bad coins drive out good coins. In the market, "processing" of public data has become a social norm. For example, in order to attract more consumers and capitalists, companies will modify the data they publish accordingly to attract users to choose and Corporate investment.
In addition, some companies are trying to make money in the name of blockchain. After seeing the benefits brought by blockchain, some companies rushed to enter the market before they understood the operation of blockchain in order to be the first to enter this trend and obtain high profits; some even used blockchain gimmicks to do so. Make money wantonly and retreat quickly after obtaining high profits. This blind application of blockchain has caused some companies that really want to apply and develop blockchain to gradually withdraw from the market, while some companies that mainly focus on making money are still active in the market, which has greatly affected the development of blockchain. normal development trajectory.
Although the blockchain has the core technology to create new trends, because it is still in its infancy and is not mature enough in all aspects, it will still bring about various problems such as "coin speculation", which have become obstacles to the blockchain stumbling blocks to chain development.
Will the increase in entrants accelerate the bursting of the blockchain bubble?
Relevant data shows that from November 2015 to December 2017, the growth rate of blockchain-related occupations reached 631%. However,In this huge data, there are some companies that join the blockchain ranks with the mentality of "getting a profit and leaving", which disrupts the normal development of the blockchain in the market and further promotes the bursting of the blockchain bubble. .
Different from previous years, blockchain has developed very well in recent years, and its application scope has expanded to various fields such as finance, education, government, cloud computing, medical care, and insurance. As the number of entrants gradually increased, many irrationalities appeared in blockchain applications, causing batches of contestants to withdraw.
Recently, a WeChat group called "Blockchain without Sleep at Three O'Clock" has aroused heated discussion. In this group, some well-known people from the industry gathered to talk about blockchain and Bitcoin day and night. Have an in-depth discussion. Among this group of people, blockchain has basically become their “belief”. It seems that if you don’t understand blockchain, you will be eliminated by the times. This kind of blindly following the trend reflects not only people's anxiety about the development of the times, but also the market's strong demand for blockchain. Furthermore, the recent popularity of blockchain concept stocks has triggered more and more investors to enter the blockchain market, causing the blockchain market to expand rapidly and create bubbles.
Furthermore, since the blockchain is still in its infancy, there are still many aspects that need to be improved. At this time, it is tentative for companies and investors to enter the blockchain. Blockchain, a technology with revolutionary significance for the times, still needs to be gradually developed. Moving forward rashly will only push the blockchain that is originally on the right track further.
Regarding the understanding of the development of blockchain, Gartner consulting firm has previously analyzed relevant aspects: a new technology basically goes through five stages, namely the embryonic stage, the popular expansion stage, the bubble bursting stage, and the upward recovery. period, maturity period. According to Gartner's analysis in 2016, blockchain is already in a period of inflated expectations. At this time, it is in a period when the bubble is about to burst, and it will take 5 to 10 years before blockchain reaches maturity. .
Will blockchain become the key to the era of change?
2017 can be said to be the year of the explosion of blockchain, with various capitals getting involved in blockchain. Although it has brought many problems to the market, the role of blockchain in market development cannot be ignored. Recently, "Three Questions about Blockchain (Economic Hotspots)", "Seizing the Opportunity of Blockchain", and "Being a Leader in the Digital Economy" published in the "People's Daily" clearly stated the impact of blockchain on various fields of the market. important role.
Issues such as delay, "pseudo-blockchain", and "coin speculation" will further attract people's attention after the blockchain bubble bursts, and more standardized market development will occur. Today, blockchain is still in its infancy. As more and more entrants enter the industry, a blockchain bubble is inevitable in the future. But after the bubble, blockchain will bring a disruptive experience to the market and usher in a new era.
Blockchain itself emphasizes "decentralization". In order to meet the changing practical needs, blockchain is upgrading to "multi-centering", which will completely break the digitalAccording to "isolated islands", a situation of comprehensive interconnection and interoperability of information can be achieved. It can strengthen the trust security system, improve transaction efficiency, and meet the application needs of the increasingly developing era.
In short, the explosion of blockchain is inevitable. Its decentralized nature avoids the monopoly of Internet giants and brings development opportunities to many entrepreneurs and investors. But at the same time, based on blockchain, it can reduce transportation costs, is open and transparent, cannot be tampered with, has strong permeability and other properties, and is more convenient for market management. In the future business world, there will be a blockchain era that "removes fakes and preserves authenticity" .

ⅧWhat exactly is Web3.0

Standard definition: Web3.0 is used to describe the potential next stage of the Internet, one that runs on "blockchain" technology A “decentralized” Internet based on

What does this mean?

The core point of Web3.0 is that Internet virtual items have ownership rights, which means that the rights to creations on the Internet can be confirmed. For example, I made an emoticon pack today and everyone is using it. My emoticon pack is very popular, but if you go online and ask who originally created this emoticon pack, maybe 10,000 people will jump out and say that they created it themselves. In other words, under the current network situation, we really have no way to determine who is the original author of this picture, but if this is a Web3.0 world, it can be.

Some netizens explained: Web3.0 is a virtual, huge, shared excel table. Every time something is generated, it is like writing something into the table, and when writing When doing this, the system will automatically generate a public key and a private key. The private key is only owned by the person who actually writes it, just like the relationship between the box and the key.

When you want to trace the creator of this picture, you only need to go to the entire network to find who has this private key. Whoever has this private key can prove that he is the owner of this picture, because Isn’t it a surprise that you are the only one who has the key to open the box?

So which industry is closest to money?

Finance. Therefore, Web3.0+ finance has now become the largest application in the field of Web3.0, decentralized finance, or DeFi for short. This DeFi entrepreneurial project covers almost all traditional financial fields in Web 3.0, including decentralized currency, securities, lending, insurance, payment, etc. Now, there are a large number of web projects. Of course, the currencies flowing on the web are not national sovereign currencies in the traditional sense, but are all cryptocurrencies.

Many Internet companies have begun to deploy Web3.0, and many programmers from large companies have resigned and started Web3.0 entrepreneurship. This should be the development trend of the Internet, but when will the trend come? An unknown.
