⑴ The financial management department interviewed 13 online platform companies. What financial chaos have you encountered?

I have not encountered financial chaos, but I often encounter financial chaos online. I see some people falling for the financial chaos. Financial traps have taken on new forms in recent years, becoming increasingly confusing and concealed, making them difficult to guard against. However, everything remains true, and we can focus on the following key areas:

1. Investment traps. Including futures, gold, silver and other precious metal transactions, spot crude oil, foreign exchange transactions, stamp and currency card transactions, agricultural product transactions, tea transactions, etc. For example, various foreign exchange trading platforms with leveraged transactions registered in Hong Kong, Australia, the United States, the United Kingdom and other places have servers built outside the mainland, and under the supervision of local regulatory bureaus, they build virtual trading platforms and falsify market data. Investors can enjoy the benefits of profit. Taking advantage of transaction slippage, altering data, and defrauding huge profits. Domestic postal currency card trading platforms use high profits as bait to attract investors to download the platform and enter the market for additional investment, then manipulate prices, harvest customers or run away.

5. Virtual currency trap. Using blockchain technology as the slogan and digital currency as the guise, they conduct pyramid schemes, register free mining machines, attract new customers, and encourage customers to buy mining machines to increase mining volume in order to obtain greater profits. Eventually, investors gradually entered the game and invested more and more, taking over the market for the dealer.

⑵ Why are virtual currencies so popular after increasing hundreds of times in 3 months?

Many virtual currencies fell by more than 30% today, causing panic among many retail investors, but it can It is foreseen that the market will gradually start to recover.

The virtual currency market has been booming since March this year and reached its peak in May. The author bought several thousand XRP coins in March, sold the XRP coins and bought some other virtual currencies in the middle. In less than 2 months, I made more than 100,000 yuan at the peak.

However, the recent currency market has been full of lamentations, and the continuous decline has caused many people to panic and sell stocks.

Spurred by the explosion of the digital currency market, domestic blockchain ICO projects have sprung up like mushrooms after a spring rain. The investment return rate of blockchain ICO projects is also astonishingly high. It is common to see rates below 5 times, 10 Times or more are not uncommon. Within three or four months, Quantum Chain's 70 times, Gongxinbao's 60 times, and ETP's 50 times shocked the entire market.

The reason why the currency market was so popular in the first place was, on the one hand, the development of the global blockchain industry, and on the other hand, the domestic stock market was trapped, purchase restrictions in the property market were imposed, and postal currency cards were rectified. Money from the stock market, property market, and stamp money cards all flow into the currency market, which leads to an increase in the overall virtual currency market value.

Today’s crazy ICO market has caused a downturn in the two-tier market of the entire exchange. A white paper can raise tens of millions or even hundreds of millions of dollars. After the successful fundraising, the founding team will definitely be eager to cash out and sell the Bitcoin and Ethereum raised in their hands, resulting in selling behavior. Investors put all their money into the ICO market.The inflow of funds into the currency market has been greatly reduced. ICOs will always be regulated, not across the board, but to better regulate and guide the healthy development of the industry.

As the overall market is still on a growth trend, every drop is an opportunity to make money, and it is only a matter of time before the market picks up.

⑶ This opportunity to make a fortune overnight, the aunt has come to kill you...

I heard that there is a mysterious oriental force in the investment market called the Chinese aunt...
< br />Your uncle is still your uncle, but your aunt is no longer the aunt she used to be.

Wherever Auntie goes, from big gold chains to big gold watches, to A-shares being cut off at high positions, now Auntie has once again entered the world of blockchain.

01

One day in the currency world is one year in the world.

Some time ago, Binance just announced its first quarter profit of US$150 million, surpassing 90% of A-share listed companies.

Indeed, there has never been a technological revolution that has created huge wealth effects in a very short period of time like the blockchain.

Many people involved fell into a state of collective carnival and could not extricate themselves. Money and wealth gathered gold diggers from all walks of life.

Now that aunts have entered the blockchain world, will they become the leverage in the currency circle?

The factory director has recently been researching blockchain and made friends with some practitioners in the industry.

At the Macau Blockchain Conference a few days ago, a group of rich and free aunts took the spotlight with their "one-day trip pose" in front of the booth...

The aunts are here China has a very strong presence and is often marked by the times. Macau is just the tip of the iceberg.

02

As far as financial management is concerned, aunts have always been the most loyal participants in the fashionable wealth-making movement.

From gold in 2013, to the stock market and P2P financial management in 2015, to the property market and stamp cards in 2016, to funds in 2017, and today’s virtual currencies.

Make money wherever you go.

Blockchain broke into their field of vision with the aura of getting rich overnight. The currency circle created a new round of financial management movement. Virtual currency has naturally become a new and charming thing in the eyes of fashionable aunts. .

The strange thing is that aunts usually eat leftovers for a few days and are reluctant to throw them away, and they are reluctant to replace furniture after a lifetime, but when it comes to investment and financial management, they are actually willing to invest millions in a project.

The factory director is a coward.

For example, in 2015, the aunt who brought millions of cash to open an account for stock trading heard that stock trading was very profitable, so she took out all her savings without telling her family to make money to buy a house for her son.

The sources of news for aunts are generally recommendations from acquaintances, media reports, and some road shows. There are not many industry resources, and the news is generally lagging behind.

Most aunts choose to form groups to participate in currency conferences in order to inquire about news and participate in token investments. It is best to get a discount.

However, after the ICO investment bubble burst last year, insider trading became rampant. Projects were carefully packaged from business plan writing, fundraising roadshows, ICO market value management, investor relationship maintenance, etc., and ordinary people often couldn’t tell the difference. Good or bad.

If you can’t even understand the white paper and buy an altcoin that breaks or returns to zero, you will be the only one left dumb.

The factory director has no way of knowing what gains or losses the aunts will gain from entering the currency circle.

However, in the past few months, words such as air currency, breakout, and supervision have appeared frequently, and the currency circle has fallen into a downturn for a while.

From this point of view, there are still very few aunts who have truly realized their dream of getting rich.

03

What’s more, the world of blockchain itself is a new thing, and the threshold for judging value coins and air coins is already relatively high.

Many people are still novices wearing expert coats.

Therefore, we should be cautious and cautious when it comes to speculation in altcoins.

This is a 7 times 24-hour market, and there is no limit on the rise or fall. Apart from eating, drinking and sleeping when necessary, you basically just watch the market.

Although tokens are accompanied by returns of hundreds or even thousand times, the risk of returning to zero is too high.

In an impetuous society where a basement can sell for tens of millions, it is easy to believe in miracles.

However, once a general succeeds, a win-win situation rarely occurs in the capital market. The birth of rich people in the currency circle means that a group of investors have been cut off.

To aunties and all irrational investors, the factory director’s advice is hard to hear: don’t invest if you don’t understand. There is never a shortage of leeks in the currency world.

⑷ What is the relationship between digital currency and blockchain technology

There is a certain connection between digital currency and blockchain. They are an organic combination. Blockchain is the lowest technology of digital currency, and of course it is also one of the most important technical means. Blockchain is the most widely used and most successful in the field of digital currency. In terms of the application of blockchain technology, digital currency is one of theBuilt on the basis of technology, digital currency can also be regarded as a part of blockchain technology.

Blockchain, as a powerful technical support for digital currency, can ensure that cryptocurrency exists in an encrypted form to a certain extent. The relationship between the two can be seen as inclusive. Blockchain technology, as the most basic technical application of digital currency, helps to issue digital currency.

⑸ What is the relationship between blockchain and digital currency

Blockchain refers to a chain connected by a series of data blocks (i.e. blocks). The connection method is: The N+1 block contains the hash value of the N block. Moreover, such a chain of data blocks is simultaneously stored and maintained by a widely distributed and huge number of server nodes. Each server node has a complete copy of the blockchain. Digital currency is another form of existence and circulation of legal currency. Compared with the banknotes and coins currently in circulation, digital currency exists in a digital way. The legal existence of digital currency is legal and is based on blockchain technology. Blockchain is the underlying technology for digital currency issuance. This is also the most direct relationship between the two. They can exist independently of each other. The content of this article comes from: China Law Press "Financial Code of the People's Republic of China: Application Edition"

⑹ I would like to ask everyone what exactly is LinkToken

LinkToken (English name LinkToken ) is a digital asset designed based on blockchain technology launched by Xunlei. It refers to the workload proof of shared resources generated based on Xunlei blockchain technology in the Wanke cloud shared computing ecosystem.

The creation process of LinkToken is closely related to the economic application of Wanke Cloud intelligent hardware and shared CDN, which must be obtained by sharing network bandwidth and storage space resources with Wanke Cloud intelligent hardware. In the Wanke Cloud shared computing ecosystem, LinkToken will become a medium for users to exchange shareable computing resources, ensuring the equality of user rights and shared computing resources.

Wanke Cloud users can obtain LinkToken by sharing network bandwidth, storage space and other computing resources through Wanke Cloud smart hardware. This is closely related to the real-life business scenario applications of Wanke Cloud smart hardware and shared CDN, and is a shared An incentive tool between users and merchants in the computing ecosystem based on Xunlei blockchain technology is used to fairly measure, register and prove the provision and consumption of shared computing resources.

(6) Extended reading on the combination of blockchain and stamp cards:

1. The role of LinkToken

< p>As an incentive tool in the shared computing ecosystem, LinkToken serves as a workload proof for shared computing resources to reward users and redeem goods or services related to shared computing resources in a closed scenario; on the other hand, it serves as a proof of work for shared computing resources. Proof of consumption will be given back to all Wanke Cloud users in the future by the merchant in a closed scenario.

Specifically, merchants use LinkToken to obtain idle computing resources contributed by WankeCloud users, and users use LinkToken to redeem shared computing-related products and services, such as video networksSite member privilege services, network acceleration services, cloud storage services, shared content services, game content services, etc.

As more merchants join the shared computing ecosystem equipped with Xunlei blockchain technology, LinkToken will continue to present more application scenarios.

2. How to obtain LinkToken

The first method: users purchase Wanke cloud smart hardware devices and choose to activate the Wanke reward plan, and share computing resources such as bandwidth and storage. Obtain Link Token rewards according to the Link Token generation rules.

Second type: Merchants obtain LinkToken from users by providing users with exchange-related products and services for shared computing in a closed scenario and use it for the consumption of shared computing resources.

⑺ What exactly is blockchain

Let’s talk about some basic concepts first.

The network said that blockchain is a new usage model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. It is essentially a decentralized database, and as the underlying technology of Bitcoin, it is a series of data blocks generated by cryptography.

We try to translate "what is blockchain" into "human language".

The definition refers to the "decentralized database" nature of blockchain3354. This is very different from the traditional "centralized database" in storage, update and operation.

A centralized database can be thought of as having this shape:

For example, if I want to use Alipay to pay a Taobao seller, all data requests from when I make money to when he receives the money will be centrally processed by Alipay. The advantage of this data structure is that as long as Alipay is responsible for the efficient and safe operation of the system, others can unconditionally believe it without worrying; the disadvantage is that if there is a problem with Alipay, such as being hacked, the server being burned, a traitor appearing, and the company running away (Of course, the possibility of the above is extremely low), the balance details and other information in our Alipay will be confused.

Then some people think that this kind of low-probability event can use any technical means to avoid individual risks, and not only hand over the data to a centralized organization. For example, everyone can store and process data.

The database structure may look like this:

This picture is a schematic structural diagram of a "distributed database". Each point is a server, they all have equal rights to record and calculate data, and information is spread point-to-point. At first glance, it seems that it can indeed resist the risk caused by the crash of a certain node, but it is also very confusing and inefficient intuitively. Who will handle my information, and who has the final say on the results?

At this time, the "consensus mechanism" in the definition of blockchain comes into play. The consensus mechanism mainly "stipulates" the following things: who will process a data request (what qualifications are required); who will verify the results (to see if he has handled it well); how to prevent processors and verifiers from colluding with each other, etc.

Some people may like to be questioned when a "rule" is made. In order to form a stronger consensus, in addition to making the rules more reasonable, they must also be more attractive so that people are interested and motivated to participate in data processing. This involvesRegarding the incentive mechanism of the public chain. We will start again later when we discuss the classification of blockchain and the role of digital currencies.

When we hand over a transaction to a distributed network, there is also a "psychological threshold": there are so many nodes that can process information, and I don't know any of them (unlike Alipay, if it hurts me, I can go and file a lawsuit against it). They all have my data, why should I trust them?

At this time, encryption algorithm (the last descriptive word in the definition of blockchain) comes on stage.

In the blockchain network, the data requests we send will be encrypted according to cryptographic principles into a string of characters that the recipient cannot understand at all. Behind this encryption method is the support of a hash algorithm.

Hash algorithms can quickly convert any type of data into hash values. This change is one-way irreversible, deterministic, random, and anti-collision. Because of these characteristics, the person handling my data request could record the information for me, but they had no idea who I was or what I was doing.

So far, the working principle of the decentralized network has been introduced. But we seem to have overlooked one detail. The previous diagram is a net. Where are the pulleys and chains? Why do we call it blockchain?

To understand this matter, we need to clarify a few knowledge points first:

The previous picture is actually a "macro" database perspective, showing the basic rules and processes of the blockchain system for processing information. . And specifically at the "micro" data log level, we will find that the ledger is packaged, compressed, stored in blocks, and strung together in chronological order to form a "chain structure", like this:

Figure Each ring in can be regarded as a building block, and many links are linked together to form a blockchain. Blocks store data, unlike ordinary data storage: on a blockchain, the data in a later block contains the data in the previous block.

In order to academically explain the fields of each part of the data in the block, we tried to use a book metaphor to describe what a blockchain data structure is.

Usually, when we read a book, we read the first page, then the second and third pages. The spine is a physical existence that fixes the order of each page. Even if the book is scattered, the order of each numbered page can be determined.

Inside the blockchain, each block is marked with a page number, the second page contains the content of the first page, the third page contains the content of the first and second pages. The tenth page contains the previous Nine pages of content.

It is such a nested chain that can be traced back to the original data.

This brings up an important attribute of blockchain: traceability.

When the data in the blockchain needs to be updated, that is when new blocks are generated in sequence, the "consensus algorithm" comes into play again. This algorithm stipulates that a new block can only be formed if it is recognized by more than 51% of the nodes in the entire network. To put it bluntly, it is a matter of voting, and it can be elected if more than half of the people agree. This makes the data on the blockchain difficult to tamper with. If I were to force a change, there would be too many people to bribe and the cost would be too high to be worth it.

This is what people often call the blockThe "immutable" nature of the chain.

Another reason why blockchain gives people a sense of trust is because of "smart contracts."

Smart contracts are commitment agreements defined and automatically executed by computer programs. It is a set of transaction rules executed by code, similar to the current automatic repayment function of credit cards. If you turn on this function, you don’t have to worry about anything. The bank will automatically deduct the money you owe when it is due.

When your friend borrows money from you but doesn't remember to pay it back, or makes excuses not to pay it back, smart contracts can prevent breach of contract. Once the terms in the contract are triggered, such as when it is time to pay back the money, or there is a limit in his account, the code will automatically execute, and the money he owes you will be automatically transferred back whether he wants it or not.

Let’s briefly summarize. Blockchain technology is mainly decentralized, difficult to tamper with, and traceable, which represents more security and trustlessness. But it also brings new problems: redundancy and inefficiency, which requires many nodes to agree with the rules and actively participate.

This concludes the "drying" section. Next, let’s talk about unofficial history and the official history of blockchain.

A new technology is often used to serve a certain task.

Or goals. So where was blockchain first used, and who came up with it first?

Let's go back to 2008.

On September 21, Wall Street investment banks collapsed one after another, and the Federal Reserve announced that it would convert the only two remaining investment banks (Goldman Sachs Group and Morgan Stanley) into commercial banks; it hoped to survive the financial crisis by absorbing savings. On October 3, the Bush administration signed a $700 billion financial rescue package.

Twenty-eight days later, on November 1, 2008, a new post appeared in a cryptography mailing group: "I am developing a new electronic currency system that is completely peer-to-peer and does not require a third party. Three-party trust institution." The text of the post is a paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System", signed by Satoshi Nakamoto.

The paper explains the design of this peer-to-peer electronic cash system with a more rigorous logic. It first discusses the problem that financial institutions are subject to "trust based" (based on credit), and then explains step by step how to achieve "no third-party agency" , and cleverly solved the technical problems left by the predecessors.

Two months later, Satoshi Nakamoto released the first version of the open source Bitcoin client and mined 50 Bitcoins for the first time. The block that generated the first batch of Bitcoins is called the "Genesis block". The genesis block was compiled into block 0 and was not uploaded to the chain. It took Satoshi Nakamoto 6 days to mine this block. This also sparked discussion in the bitcointalk forum. Bitcoin "believers" thought of the Bible, "God created the heavens and the earth in six days, and then rested on the seventh day."

Although decentralized, token, and econo do not appear in the paperConcepts such as my (economy), but Satoshi Nakamoto explained in detail how blocks and chains work in the network. So, there is Block Chain.

This paper later became the "Bible" of the "Bit Cult", technology became the cornerstone of faith, and developer documentation became the "Code of Hammurabi".

After that, Bitcoin realized the first real-life payment by exchanging pizza, WikiLeaks, whose account was blocked by the US government, miraculously survived by relying on Bitcoin, Satoshi Nakamoto's "decentralization" and retirement, and the appearance of the real and the fake A series of legends such as and refutation of rumors, combined with the expectations, imagination and speculation of later generations, became "Bible stories".

There are also people who are not satisfied with the world described in the "Old Testament" and start new sects, write the doctrines into white papers, and tell the story of their faith in the ten years after Bitcoin. Just like the writing of the 66 books of the Bible spanned 1,500 years, and after 2,000 years of interpretation, Christianity has divided into 33,000 branches.

CoinMarketCap shows that there are more than 4,900 types of digital currencies, and the overall digital currency market size is nearly 140 million yuan. Bitcoin still leads the entire digital currency market with a market share of 66%, and the recent price has been hovering around US$7,200 per coin.

So many currencies have different functions and are divided into different categories: digital currencies represented by Bitcoin are positioned as "digital gold" and have certain value storage and hedging characteristics; Ethereum The digital currency represented by Bitcoin has become the "operational fuel" in its network system; the stable currency represented by USDT and Libra has good payment properties due to its low volatility; the digital currency issued by the central bank represented by DCEP will definitely To a certain extent, it replaces M0, allowing commercial institutions and ordinary people to receive and pay without delay when they are out of cash and disconnected from the Internet.

It can be seen that after 10 years of development of blockchain technology, the first and largest application is digital currency.

Digital currency has also become an attractive reward for participants to maintain the public chain.

So besides digital currency, where else can blockchain technology be used?

Let us recall what the essence of blockchain is—a decentralized database, and its corresponding characteristics: traceability, publicity, anonymity, and tamper-proofing. In theory, you can try to use blockchain to transform traditional scenarios that use centralized databases to see if they are suitable.

Next, let’s talk about several industries and scenarios where blockchain has been successfully implemented:

Blockchain can prove the existence of a certain file or digital content at a specific time through hash timestamps, providing judicial authentication, Identity proof, property rights protection, anti-counterfeiting traceability, etc. provide perfect solutions

In the field of anti-counterfeiting traceability, blockchain technology can be widely used in various fields such as food and medicine, agricultural products, alcohol, and luxury goods through supply chain tracking.

Give two examples.

Blockchain can allow government data to be run and greatly streamline service processes

The distributed technology of blockchain can allow government departments to be centralized on one chain.There is a service process to deliver smart contracts. As long as the service person passes the identity authentication and electronic signature in one department, the smart contract can be automatically processed and transferred, and all subsequent approvals and signatures can be completed in sequence.

Blockchain invoices are the earliest use of blockchain technology in China. The tax department launched the "Tax Chain" platform for blockchain electronic invoices. The tax department, the issuer, and the payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing for transactions" and "instant reimbursement after invoicing" - in seconds Level invoicing and minute-level reimbursement accounting greatly reduce tax collection and management costs, and effectively solve problems such as data tampering, over-reporting of one ticket, and tax evasion.

Poverty alleviation is another practical application of blockchain technology. Utilize the characteristics of openness, transparency, traceability, and non-tampering of blockchain technology to achieve transparent use, precise investment, and efficient management of poverty alleviation funds.

Give two examples as well.

The eID network identity operation agency guided by the Third Research Institute of the Ministry of Public Security is jointly developing a "digital identity chain" with Gongyilian, which will be issued to Chinese citizens based on the citizen's identity number as the root and cryptographic algorithm. Since it was put into operation, the eID digital identity system has served the full life cycle management of 100 million eIDs, effectively alleviating the problems of personal identity information being fraudulently used, abused and privacy leaked.

Odaily Planet Daily compiled 5 identity chain projects registered with the Cyberspace Administration of China

Blockchain technology naturally has financial attributes

In terms of payment and settlement, under the blockchain distributed ledger system, there are many markets Participants jointly maintain and synchronize a "general ledger" in real time. In just a few minutes, they can complete payment, clearing, and settlement tasks that currently take two or three days to complete, reducing the complexity and cost of cross-bank and cross-border transactions. At the same time, the underlying encryption technology of the blockchain ensures that participants cannot tamper with the ledger, ensuring that transaction records are transparent and safe. Regulators can easily track on-chain transactions and quickly locate high-risk capital flows.

In terms of securities issuance transactions, the traditional stock issuance process is long, costly and complicated. Blockchain technology can weaken the role of underwriting institutions and help all parties establish a fast and accurate information exchange and sharing channel. The issuer can handle the issuance on its own through smart contracts. , regulatory authorities conduct unified review and verification, and investors can also bypass intermediaries for direct operations.

In terms of digital bills and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises, upstream and downstream suppliers, financial institutions, etc. The core enterprises issue accounts receivable vouchers to their suppliers. After the bills are digitized and uploaded to the chain, they can be uploaded to the supplier Transfer between them, each level of supplier can realize the corresponding amount of financing with the digital bill certificate.

Give me an example.

The China Enterprise Cloud Chain, jointly launched by ICBC, Postal Savings Bank of China, 11 central enterprises, etc., has covered 48,000 enterprises since its establishment in 2017, and the amount of rights confirmed on the chain has reached 1,000billion, factoring financing reached 57 billion yuan, and cumulative transactions reached 300 billion yuan. After receiving the loan application, financial institutions can verify the authenticity of the contract on the chain and whether the contract has been verified multiple times (multiple loans); the smart contract automatically clears and settles, reducing costs and increasing efficiency; at the same time, the accounts payable of core enterprises can have The corresponding vouchers will be split by the first-level suppliers and handed over to the second- and third-level suppliers in the chain to help them with financing; core enterprises can also use this to understand whether the entire chain is operating normally and avoid emergencies. Redemption pressure.

Blockchain technology will greatly optimize the existing use of big data and play a huge role in data circulation and sharing

The aforementioned areas are areas that we are relatively familiar with. As more new technologies develop, blockchain may be able to be combined with them and play a role in unexpected cross-fields and new scenarios that are currently unforeseen.

In the future, the Internet, artificial intelligence, and the Internet of Things will generate massive amounts of data. The existing centralized data storage (computing model) will face huge challenges. Edge storage (computing) based on blockchain technology is expected to become a future solution. Furthermore, the non-tampering and traceability mechanism of blockchain ensures the authenticity and high quality of data, which becomes the basis for the use of all data such as big data, deep learning, and artificial intelligence.

Finally, blockchain can realize multi-party collaborative data calculations while protecting data privacy, and is expected to solve the problems of "data monopoly" and "data islands" and realize the value of data circulation.

In response to the current blockchain development stage, in order to meet the blockchain development and use needs of general business users, many traditional cloud service providers have begun to deploy their own BaaS ("Blockchain as a Service") solutions. The combination of blockchain and cloud computing will effectively reduce enterprise blockchain deployment costs and promote the implementation of blockchain usage scenarios. In the future, blockchain technology will also play an important role in many fields such as charity, insurance, energy, logistics, and the Internet of Things.

During this trial process from traditional technology to blockchain, we found that when certain scenarios have stronger demands for traceability, tamper-proofing, and decentralization, they also have problems with the weaknesses of blockchain (such as performance). , the requirements are not high, and this field is quite suitable for combining blockchain.

At the same time, in the process of blockchain evolution, it has also developed from a highly decentralized public chain accessible to everyone to a consortium chain with different permissions and maintained by multiple centers. Balances the advantages and disadvantages of the two systems.

Typical examples of alliance chains include: FISCO BCOS jointly developed by WeBank and the Golden Alliance Open Source Working Group, Fabric, a major contribution from IBM, and Ant Alliance Chain led by Ant Blockchain, etc.

These trustless systems represent more secure data authentication and storage mechanisms, where data is effectively authenticated and protected. Businesses or individuals can exchange or enter into contracts digitally, where these contracts are embedded in code and stored in transparent, shared databases where they cannot be deleted, tampered with, or revised.

Bold predictions about contracts, reviews, tasks, and payments in the future worldAll will be digitized with a unique and secure signature. The digital signature will be permanently identified, authenticated, legalized and stored, and cannot be tampered with. There is no need for an intermediary to guarantee each of your transactions. You can conduct transactions without knowing the basic information of the other party. While improving information security, it effectively reduces transaction costs and improves transaction efficiency.

Generally speaking, there has been a lot of progress in the implementation of blockchain compared to two years ago.

Many improvements are at the bottom of the system, and users cannot directly see that blockchain is used, but they have actually benefited from it; some applications are still in pilot mode, and users have not yet been able to experience it. In the future, blockchain is expected to be used on a large scale and become one of the Internet infrastructure.

I hope that after reading this, you have a general understanding of what blockchain is and what blockchain can do.

Related Q&A: What is blockchain

Blockchain is actually equivalent to a disintermediated database, which is composed of a series of data blocks. Each of its data blocks contains information about a Bitcoin network transaction, which is used to verify the validity of the 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. distributed ledger.

In a broad sense, blockchain is actually a distributed infrastructure and computing method, which is used to ensure the security of data transmission and access.

Blockchain infrastructure:

Blockchain is composed of six infrastructures: data layer, network layer, consensus layer, incentive layer, contract layer and usage layer.

⑻ How blockchain technology can transform electronic data into legal and effective electronic evidence

With the rapid development of the Internet and information technology, a large amount of evidence in litigation is gradually stored in electronic data Presented in the form of blockchain technology, in judicial practice, how to overcome the natural defects of electronic data that are "difficult to obtain evidence, easy to lose, and easy to forge" and ensure that it can be used as evidence in court?
Blockchain is based on technical features such as multi-party consensus, non-tampering, transparency and traceability, which can effectively solve the problems of electronic evidence such as "large quantity, scattered evidence, difficulty in obtaining evidence, easy to be tampered, and difficult to identify", and realize "electronic data "Transforming to "legal and effective electronic evidence" will facilitate the identification of electronic data evidence and improve litigation efficiency in the field of judicial evidence storage.
On September 3, 2018, the Supreme People's Court issued the "Regulations on Several Issues Concerning the Trial of Cases by Internet Courts", which for the first time determined that on-chain data can be used as a basis for judicial admission.
On May 18, 2021, the Supreme People's Court issued the "People's Court Online Litigation Rules" and came into effect on August 1. For the first time, it stipulated the scope of effectiveness of blockchain storage and clarified the scope of blockchain storage. After the data is uploaded to the chain, it is presumed to be valid without tampering. At the same time, the authenticity review rules for blockchain storage data after and before they are uploaded to the chain have been established.
This not only promotes the development of blockchain technology and litigation rulesIntegration has opened up the development path of the blockchain judicial model.
Yibaoquan is one of the first companies to register for blockchain information services through the Cyberspace Administration of China. It uses self-developed security chain technology to build a consortium chain, and combines blockchain with justice to build a data storage system. The notarization system can well solve the credibility problem of the entire chain of electronic data from generation and storage to notarization and proof:
When uploading to the chain, blockchain technology is used to store the data in advance with multiple parties. , to ensure the originality and integrity of the evidence-stored data; after being uploaded to the chain, the data is synchronized with each node on the alliance chain for backup and retention, ensuring the credibility and security of the data; during litigation, the evidence can be verified at multiple judicial nodes , extraction, and relevant judicial documents can also be issued online, effectively improving the efficiency of rights protection.
