『一』What are the technical classifications of blockchain?

1. Public chain, no official organization or management agency, no central server, participating nodes follow the System rules are freely accessible to the network without control, and nodes work based on a consensus mechanism. (Subversive: absolutely credible and open)
Typical case: Digital currency represents Bitcoin
2. Private chain, established within a group, the operating rules of the system are set, modified or modified according to the requirements of the group Read permissions are subject to certain restrictions, while retaining the authenticity and partial decentralization of the blockchain. (Relatively trustworthy and public)
Typical case: R3
3. Alliance chain, jointly initiated by several institutions, is between the public chain and the private chain, and has the characteristics of partial decentralization. The read permission on the District Quick Chain may be public or partially public, that is to say, multiple pre-selected nodes are designated as bookkeepers internally, and the pre-selected people compete for the book-keeping permission, and other access nodes can participate in transactions. But don’t ask about the accounting process. (The abilities of the pre-selected candidates cannot be uneven). ?
(relatively credible and public)
Existing cases: Hyperledger
Example: ?Take loan diversion as an example, when the user jumps to the other party’s webpage through our link to register, The docking party can choose to lie and say that it has not received the user's registration request. But if we put the user registration behavior on the block, if the docking party wants to receive the user registration behavior, it must pay us at the same time when receiving it.

『二』From what angles can we judge the quality of a blockchain project?

From an industry perspective, the blockchain industry has developed greatly this year. improvement. Some projects we are familiar with have quickly entered the market over a period of time. But overall, the evaluation standards for blockchain projects in the market have changed a lot. So how should we judge whether a blockchain project is good or not?

3. The quantity and quality of ecological resources

When choosing a project, we also need to have a basic understanding and analysis of the ecological resources where the project is located. For example: who are the people in the ecological resources and which resources are more important. Whether the team currently working on the project has project implementation experience, whether the core team has very strong business capabilities, whether there are talents in the team, whether the team has a very good development plan, etc.

4. How is the community atmosphere and how is the user experience?

The community atmosphere can be said to be a very important factor in the success of a company. On this platform, in addition to the company, there is also a community. Community is a very important basic condition for a good project. If a project does not have the support of a community, it will ultimately be just a shell company. If a project itself is a community composed of ordinary users, then it will only be like this in its future development. For a project to be successful, it must have the support and support of users!

『三』 What is blockchain technology What is blockchain in a popular explanation

Blockchain has been at the forefront since the end of October.

What is blockchain technology

Although blockchain has been around for more than ten years, many people still don’t know much about this technology.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. From an application perspective, blockchain is a distributed ledger.

So, why is the blockchain called the blockchain?

Because the blockchain itself is a series of linked blocks, these blocks are filled with transaction records. The blocks are much like the records of a database. Every time data is written, it is Create a block. With the expansion of information exchange, one block continues with another, and the result is called a blockchain.

What are the characteristics of blockchain technology?

Simply put, blockchain has the characteristics of decentralization, openness, non-tampering, and anonymity.

1. Decentralization:

In the blockchain system, there is no center.

In the blockchain model, it is distributed accounting and storage. Each node self-verifies, transmits, and manages information. Each node is the center, which is decentralization.

2. Openness:

The blockchain system has the characteristics of openness. The data is open and anyone can query the blockchain data and data through the public interface. Develop related applications.

3. Information cannot be tampered with:

In the blockchain system, once the data is written, the tampering cannot be undone unless 51% of all data nodes are controlled. Forge a record that does not exist. Therefore, blockchain technology has a certain degree of security.

4. Privacy and anonymity:

The cryptography technology in the blockchain can effectively achieve identity concealment.

The identity information of each node does not need to be disclosed or verified, and information transfer can be done anonymously. It can only be accessed with the authorization of the data owner, thus ensuring data security and personal privacy.

Xiao Li lent 10,000 yuan to Xiao Wang. Xiao Li found two people in common and Xiao Bai to prove it. This accounting model is a centralized accounting model, and Xiaobai is the center.

However, a year later, when Xiao Li wanted to get the money back, Xiao Wang Shikou denied that he had lent him the money. It turned out that Xiao Wang introduced Xiao Bai’s girlfriend to his company. a job.

This is the disadvantage of centralized accounting.

Xiao Li learned a lesson and gained wisdom. In the future, when someone asked him to borrow money, he said on WeChat in the village that I would lend so-and-so how much money. In this way, everyone in the village knew that Xiao Li How much money did Li lend to whom?

In this way, when Xiao Li asks for debt again in the future, the other party will not deny the issue, because a consensus mechanism has been established in the minds of the people in the village: How much did you borrow from Xiao Li? .

This is the advantage of decentralized accounting.

Because after all, there are many people to testify about this transaction. If it seems to be a fraud, it will be unless more than half of the people in the village are bought. However, the price is very high.

In fact, these characteristics of the blockchain are all to solve the problem of "trust". The rich application scenarios of the blockchain are also based on the blockchain's ability to solve the problem of information asymmetry. At the same time, Blockchain also helps achieve collaborative trust and consistent action among multiple entities.

What are the applications of blockchain?

In addition to digital currency, there are many application scenarios of blockchain.

1. Medical field

Blockchain helps realize smart medical care, such as going to the hospital to see a doctor. Through the blockchain model, the patient’s medical status, cases, treatment status, etc. are all Clearly visible, saving a lot of medical resources.

2. Copyright field

Blockchain can prove the authenticity and uniqueness of the copyright of works, from the birth to the transfer of audio, video, pictures, text and other works. Can be tracked and recorded, and form tamper-proof information.

3. Logistics field

After applying blockchain in the logistics field, goods can be traced from production to consumption.

4. Food safety

Is blockchain used for food safety? Through blockchain traceability, one can easily trace the past and present life of their food.

5. Securities trading

For example, traditional securities trading requires the coordination of multiple institutions to complete, while the blockchain system can independently complete one-stop transactions. This service can make securities trading simpler and faster.

However, many people have big misunderstandings about blockchain. The biggest misunderstanding is: blockchain = Bitcoin

In fact, blockchain and Bitcoin is not the same thing. Blockchain is the underlying technology of Bitcoin, and Bitcoin is the first application of blockchain.

『四』What are the main characteristics of blockchain technology

It is understood that compared withTraditional centralized solutions, blockchain technology mainly have the following three characteristics:

The core idea of ​​blockchain is decentralization

In the blockchain system, The rights and obligations between any nodes are equal, and all nodes have the ability to vote with computing power, thus ensuring that the recognized result is the result recognized by more than half of the nodes. Even if it suffers a severe hacker attack, as long as the number of nodes controlled by the hacker does not exceed half of the total number of global nodes, the system will still be able to operate normally and the data will not be tampered with.

The biggest subversion of blockchain is the establishment of credit

Theoretically, blockchain technology can make WeChat Pay and Alipay no longer valuable. "The Economist" gave a vivid metaphor to the blockchain: simply put, it is "a machine that creates trust." Blockchain allows people to collaborate without trusting each other and without a neutral central authority. Combating counterfeit currency and financial fraud will no longer be needed in the future.

The collective maintenance of blockchain can reduce costs

Under the centralized network system, the maintenance and operation of the system rely on the operation, maintenance and operation of platforms such as data centers, and the cost Cannot be omitted. Anyone can participate in the nodes of the blockchain. While participating in the recording, each node also verifies the correctness of the recording results of other nodes, which improves maintenance efficiency and reduces costs.

In one sentence, blockchain touches money, trust and power, which are the fundamental foundations on which human beings rely for survival.

『Wu』 What are the main technical characteristics of blockchain?

“Blockchain is a shared distributed database technology, and its advantages are mainly reflected in distributed Decentralization, trustless system and non-tampering and encryption security.”
1. The meaning of blockchain technology
Blockchain (BlockChain) technology is a method that uses decentralized consensus Mechanism to maintain a complete, distributed, non-tamperable ledger database technology, which allows participants in the blockchain to implement a unified ledger system without establishing a trust relationship. Blocks are public ledgers and are maintained at multiple points; chains are stamped with timestamps and cannot be forged. Blockchain is essentially a technology that values ​​security and credibility over efficiency.
There is a database behind all current systems, which is a big ledger. Then who will keep this ledger becomes very important. Now it’s 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 The ledger during this period will beThe content is sent to everyone else in the system for backup. In this way, everyone in the system has a complete ledger.
Thus, the data becomes very secure. 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. Therefore, it can be considered that blockchain technology is a way for all people to participate in accounting, and it will bring about innovation in accounting methods.

『Lu』Characteristics of blockchain technology

The five basic characteristics of blockchain technology are as follows:
1. Characteristics of blockchain technology 1: distributed database< br>Every party on the blockchain has access to the entire database and its complete history. No single party controls the data or information. Each party can directly verify the records of its trading partners without the need for a middleman.
2. Blockchain technology feature 2: Peer-to-peer transmission
Communication occurs directly between peers, rather than through a central node. Each node stores and forwards information to all other nodes.
3. Blockchain technology feature three: Transparent anonymity
Any user with access to the system can see each transaction and its associated value. Each node or user on the blockchain has a unique address consisting of more than 30 letters and numbers, which is used to identify itself. Users can choose to remain anonymous or provide proof of their identity to others. The addition of the blockchain occurs at one of these addresses.
4. Blockchain technology feature four: Irreversibility of records
Once a transaction is entered in the database and an account is updated, the records cannot be changed because they are linked to every transaction record before them (hence the name "chain"). Various algorithms are employed to ensure that records in the database are permanent, chronologically ordered, and accessible to all other nodes on the network.
5. Features of Blockchain Technology Five: Computational Logic
The digital nature of the ledger means that blockchain transactions can be associated with computational logic and are essentially programmable. Therefore, users can set algorithms and rules that automatically trigger transactions between nodes.
Extended information:
Blockchain is a chain composed of blocks one after another. Each block stores a certain amount of information, and they are connected into a chain in the order in which they were generated. This chain is saved in all servers. As long as one server in the entire system can work, the entire blockchain is safe. These servers are called nodes in the blockchain system, and they provide storage space and computing power support for the entire blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes. These nodes are usually in the hands of different subjects, so it is extremely difficult to tamper with the information in the blockchain.thing. Compared with traditional networks, blockchain has two core characteristics: data is difficult to tamper with and decentralized. Based on these two characteristics, the information recorded in the blockchain is more authentic and reliable, and can help solve the problem of people's mutual distrust.

『撒』What is blockchain technology

Blockchain technology is a decentralized distributed database technology that can achieve data security, transparency, and non-tampering and other characteristics. It is composed of many data blocks. Each data block contains the current timestamp and the hash value of the previous data block. Data storage and management are achieved by continuously adding data blocks.
The core idea of ​​blockchain technology is decentralization. There is no central node control, but a decentralized network composed of many nodes to control the storage and circulation of data. In this kind of network, each node has the right to participate in the verification and storage of data. Any modification of data requires the consent of the majority of nodes in the network, which makes the blockchain technology non-tamperable and sensitive to inspection. Features such as centralization and transparency can ensure the security and credibility of data.
Blockchain technology can be applied to many fields, such as finance, Internet of Things, supply chain management, etc.

『8』 What is blockchain technology and what areas may it be used in the future

What is blockchain technology? Blockchain is a distributed shared accounting technology that allows all parties involved to establish a trust relationship at the technical level. Blockchain can be roughly divided into two levels: one is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, the transformation, optimization or innovative application based on the blockchain.
Blockchain has been applied in several fields. In the first field of digital assets, in addition to some points and check-in cards we have seen, it also includes various other assets, and there is a process of asset digitization.
The second area is the field of trade finance. Because the field of trade finance is originally a multi-link and multi-party participation method, blockchain can greatly improve the efficiency of the middle, making many of the original substitutes effective.
The third area uses equity, which is a company's equity like some regional equity trading centers. The purpose is to facilitate equity-to-transactions and facilitate relative circulation. At present, the multi-center blockchain system can indeed improve efficiency and reduce costs.
