『一』What is the essence of blockchain

Blockchain is essentially a decentralized distributed database, a distributed data storage, multi-center Innovative application models of various technologies such as point-to-point transmission, consensus mechanism and encryption algorithm in the Internet era.
In layman’s terms, the blockchain can be compared to a “ledger”. The traditional ledger is "centralized accounting" by one party. This new "accounting book" can be participated and shared by multiple parties on the Internet. Each participant can "accounting" and back up, and each backup is a "block". Each "block" is linearly connected to the next "block" in chronological order, and its structural characteristics make the record impossible to be tampered with and forged.
For example, if you are the one doing the accounting at home, and your parents give you a salary and let you record it in the account book, then because you are the only one keeping the accounting, you secretly spend more than ten yuan. Maybe they won't know, but now it's your parents who keep the accounts with you, so whether it's your father who wants to buy cigarettes secretly or you who want pocket money, every move will be clearly recorded in the account book.

『二』What is blockchain

What is blockchain? What changes will it bring to your future life?

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

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of cryptographic methods related to each other. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

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.

The Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations" on January 10, 2019, which will come into effect on February 15, 2019.

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-transformable. Fake distributed ledger.

So in conclusion, this is undoubtedly a new technology that changes life. In the future, the production activities of the entire society will be carried out with blockchain as the underlying logic. Many things We all have it at our fingertips, and with the integration of artificial intelligence and big data, we can easily handle things that may seem cumbersome now, such as some securities market transactions and intelligent matching of financial management activities.

To put it simply, blockchain is a network computing center that integrates people, property, machines, and goods, and packages it into a whole; putting it on an infrastructure to run it.

『三』 Popular explanation of blockchain technology

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is an important concept of Bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated by cryptographic technology. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next data block.
First of all, it is a special distributed database that is essentially readable and writable. The unit then entered into the database is a "block", which is decentralized.
It doesn’t seem to be easy to understand when explained in this way, so let’s give a simple example.

When we shop on Taobao, because neither the buyer nor the seller knows each other's credit, we need to introduce a third-party platform - Alipay. Alipay is a trustworthy platform. The buyer first gives money to Alipay. After the seller delivers the goods, the buyer receives the money and notifies Alipay, who then lends the money to the seller. In this way, there is no need to worry about credit issues in the transaction.

『四』What is blockchain technology? What exactly is blockchain? What is blockchain?

1. The so-called blockchain technology, referred to as BT (Blockchain technology), is also called distribution. Ledger technology is an Internet database technology that is characterized by decentralization, openness and transparency, allowing everyone to participate in database records.

Explain in layman’s terms: If we assume that the database is a ledger, reading and writing the database can be regarded as an accounting behavior. The principle of blockchain technology is to find out the accounting information within a period of time. The fastest and best person will keep accounts, and then send this page of information to everyone else in the entire system.

2. Blockchain is a new application model of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies.

『Lu』 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.
BlockchainTechnology can be applied in many fields such as finance, IoT, supply chain management, etc.

『撒』What is the essence of blockchain

From an academic perspective, blockchain is computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. new application models. Blockchain is essentially a decentralized database.

For example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy you something, you immediately record it and send it to all of your and his Best friends, classmates, colleagues, and various groups and circles of friends make it impossible for him to deny it anymore. This is called blockchain.

The core advantage of blockchain technology is decentralization. It can realize based on data encryption, time stamping, distributed consensus and economic incentives in a distributed system where nodes do not need to trust each other. The peer-to-peer transactions, coordination and collaboration of decentralized credit provide solutions to the common problems of high cost, low efficiency and insecure data storage in centralized institutions.
