『一』What does blockchain mean?

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, Zuowu Zhibu is the underlying technology of Bitcoin. It is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify its information. effectiveness (anti-counterfeiting) and generate the next block.

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

2. In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China’s economy, accelerate the circulation of global assets, and realize the renaissance that generations have been striving for. dream.

Puyin Group held the Puyin Blockchain Finance Guiyang Strategy Release Ceremony in Guizhou on December 9, 2016. At the meeting, the blockchain will realize the digital circulation of assets and the blockchain financial transaction model. , and discuss the application of blockchain services and social public industries.

In fact, the original English version of the Bitcoin white paper does not appear in the word blockchain, but uses chain of blocks. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.

Blockchain Applications:

Blockchain has potentially huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.

For example, Visa launched Visa B2B Connect based on blockchain technology, which can provide institutions with a lower-cost, faster and safer cross-border payment method to process business-to-business transactions worldwide. .

Be aware that traditional cross-border payments require 3-5 days of waiting and a 1-3% transaction fee. Visa also joinsCoinbase has launched its first Bitcoin debit card, while Citibank is testing running the cryptocurrency Citicoin on the blockchain.

『三』What is blockchain

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It is a bit An underlying application technology of the currency. Traditional information storage and exchange will go through a server, that is, a database, and all information can be found or modified in this database.
There are three types of blockchain: public chain, alliance chain, and private chain.
1. Public chain: It is composed freely by everyone who participates in it. Anyone can enter or exit at any time without any restrictions, but the information during your entry or exit will be known or recorded by the participants. .
2. Alliance chain: It is formed by multiple individuals or groups, and the participating people or groups are designated in advance or can only enter after being reviewed later. It has a certain access mechanism. , the writing and reading permissions of its information can also be determined by the person or group formed.
3. Private chain: It is equivalent to an individual or a certain unit using blockchain technology to store information. Only he has the authority to write information, and he can decide not to disclose the information to the public.

『四』What does blockchain mean and what are its main uses

In recent years, a hot word has appeared frequently on the Internet, that is " "Blockchain", this word gives people a very noble and powerful feeling, but many people don't know what blockchain means? And what are the main uses of blockchain? Let’s take a look at the relevant content that has been issued.

Blockchain Blockchain is actually equivalent to a disintermediated database, which is composed of a string of rubber 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 other words, blockchain is essentially a decentralized database.

In a narrow sense, blockchain is a chain data structure that combines data blocks in chronological order and is cryptographically guaranteed. Distributed ledger that cannot be tampered with or forged. Broadly speaking, blockchain is actually a distributed infrastructure and computing method that is used to ensure the security of data transmission and access.

In addition, the blockchain is composed of six infrastructures: data layer, network layer, consensus layer, incentive layer, contract layer and application layer. Regarding its role, blockchain is mainly used to solve the trust and security issues of transactions. The above is the relevant content about the meaning and function of blockchain. I hope it can help friends in need.

Characteristics of blockchain:

1. Deposit certificate< /p>

The "non-tamperable" feature of blockchain provides a solution to the problem of "certificate storage" in economic and social development. As long as the authenticity of the on-chain information and data can be ensured, the blockchain can solve the problem of "storage" and "certification" of information.

For example, in the field of copyright, blockchain can be used to store electronic evidence, which can ensure that it is not tampered with, and can link original platforms, copyright bureaus, judicial agencies and other parties through distributed ledgers, which can greatly Improve the efficiency of handling infringements.

2. Sharing

The "distributed" characteristics of the blockchain can break through the "data barriers" between departments and achieve information and data sharing. Different from centralized data storage, the information on the blockchain will be distributed to each node through point-to-point broadcasting, and all information can be "truthfully recorded" through "whole network witness".
