This collective study by the Political Bureau of the Central Committee specifically emphasized "blockchain", which opened up imagination space for the development and application of blockchain.

From a technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency.

These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for the blockchain to create trust. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

② What is blockchain in simple terms

Blockchain is a term in the field of information technology. Essentially, it is a shared database. The data or information stored in it has the characteristics of "unforgeability", "whole process traceability", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
On January 10, 2019, the Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations". Blockchain has entered the public eye and become the focus of society. From the science and technology angleFrom a technical perspective, blockchain involves many scientific and technological issues such as mathematics, cryptography, the Internet, and computer programming.
Extended information:
From an application perspective, in short, blockchain is a distributed shared ledger and database, which is decentralized, non-tampering, traceable, traceable, and collective. Maintenance, openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for establishing trust in the blockchain. The rich application scenarios of blockchain are basically based on the fact that blockchain can solve the problem of information asymmetry and achieve cooperation, trust and coordinated action among multiple entities.
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. Essentially, it is a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks associated with cryptographic methods. Each data block contains a batch of Bitcoin network transaction information to verify the validity of its information (anti-counterfeiting) and generate the next data block [8]. In fact, the word blockchain does not appear in the original English Bitcoin white paper, but blockchain. In the Chinese translation of the earliest Bitcoin white paper [9], blockchain was translated into blockchain language. This is the earliest time when the Chinese word "blockchain" appeared.

The rich application scenarios of blockchain are basically based on its ability to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects. Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

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.

⑥ What does area block mean?

Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained".

Each block contains the cryptographic hash of the previous block, the corresponding timestamp, and transaction data (usually represented by a hash value calculated using the Merkle tree algorithm), like this The design makes the block content difficult to tamper with. Distributed ledgers connected by blockchain technology can effectively record transactions between two parties and permanently verify the transaction.

At present, the biggest application of blockchain technology is digital currency, such as the invention of Bitcoin. Because the essence of payment is to "add the reduced amount in account A to account B." If people have a public ledger that records all transactions of all accounts to date, then for any account, people can calculate the amount of money it currently holds.

The blockchain is precisely the public account book used to achieve this purpose, which saves all transaction records. In the Bitcoin system, the Bitcoin address is equivalent to the account, and the number of Bitcoins is equivalent to the amount.

It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoins. The information of online transactions 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.
