❶ Popular explanation of blockchain technology

A popular explanation of blockchain technology is as follows:

To put it simply: blockchain is the use of a package of existing A new generation of network system formed using advanced network technology. This network system has a new structure, a new mechanism, and unprecedented new value. Five major technologies or innovations are specifically used: encryption technology, P2P network technology, distributed storage technology, consensus mechanism, and smart contracts.

Essentially: it is a shared database, and the data or information stored in it is "unforgeable", "full-process traces", "traceable", "open and transparent" and "collectively maintained" ” and other characteristics. Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.

2. Openness.

In addition to the encryption of private information of all parties to the transaction, the blockchain data is open to everyone and provides a flexible script code system. The entire system information is highly transparent and within the rules specified by the system. Nodes cannot deceive each other.

3. Autonomy.

Consensus technology, smart contracts.

❷ What is blockchain technology? What exactly is blockchain?

Blockchain technology is one of the top ten typical judicial technology applications on the Internet. 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. In fact, it is a decentralized database. Blockchain, as the underlying technology of Bitcoin, 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 the validity of its information (anti-counterfeiting) and generate the next data block.

Blockchain originated from Bitcoin. On November 1, 2008, a person who called himself Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology, timestamp technology, and block technology. The concept of electronic cash system framework such as chain technology marks the birth of Bitcoin.

The birth of blockchain:

The concept of blockchain was first proposed by Satoshi Nakamoto in 2008. In the following years, blockchain became the core component of the electronic currency Bitcoin: a public account for all transactions. By using peer-to-peer networks and distributed timestamp servers, blockchain databases can be autonomously managed.

The blockchain invented for Bitcoin made it the first digital currency to solve the problem of repeated consumption. Bitcoin design has become a source of inspiration for other applications. December 20, 2016, Digital Currency Alliance—China FinTech Digital Currency AllianceAnd the FinTech Research Institute is officially under preparation.

❸ 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.

❹ What technology is blockchain?

1. The reason why blockchain is popular is because its functions are very practical. Blockchain can make information more fidelity. Blockchain technology can be applied to many fields and scenarios, including some social management scenarios, and it is necessary to further broaden the horizons of research and development of blockchain technology.
2. Blockchain is essentially a database technology, specifically a ledger technology. A ledger is a set of records that records changes in assets and transactions in one or more accounts. It is actually a database with the simplest structure. The running accounts we usually write down in small notebooks and the statements sent by the bank are all typical ledgers.
3. Blockchain is a distributed ledger with multi-party participation, and is called a technology "born to solve trust problems". The essential difference between the digital world and the physical world is that things in the physical world really exist and cannot appear or disappear out of thin air. However, data in the digital world can be deleted, altered or copied out of thin air without leaving any trace. But with blockchain technology, the digital world can be as real and trustworthy as the physical world.

❺ Introduction to Blockchain Technology What is Blockchain Technology

1. Blockchain technology is one of the top ten typical judicial technology applications on the Internet.

2. 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". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.

3. Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer.

4. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, data verification mechanisms, etc. ; The consensus layer mainly encapsulates various consensus algorithms of network nodes; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and Smart contracts are the basis of the programmable features of the blockchain; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.

5. The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". Among them, "the minority obeys the majority" does not entirely refer to the number of nodes, but also to computing power. , number of shares, or other characteristic quantity that a computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result. Taking Bitcoin as an example, Caizihe uses proof of work. Only by controlling more than 51% of the accounting nodes in the entire network can it be possible to forge a non-existent record. When there are enough nodes joining the blockchain, this is basically impossible, thus eliminating the possibility of fraud.

❻ What is blockchain technology

Blockchain technology is a decentralized distributed database technology that can achieve data security, transparency, 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.

❼ What is blockchain technology? What exactly is blockchain?

1. The so-called blockchain technology, referred to as BT (Blockchain technology), is also called Distributed 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 canSeen as a kind of bookkeeping behavior, the principle of blockchain technology is to find the person with the fastest and best bookkeeping within a period of time, let this person do the bookkeeping, and then send the information on this page of the ledger to the entire Everyone else in the system.
