What does the public chain of virtual currency mean
This is two different concepts. According to different standards, blockchain can be classified into three categories:
& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain
&# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain
&# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain
the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process
Public chain is also known as "public chain", and public chain refers to the blockchain that anyone in the world can read and send transactions, and transactions can be effectively confirmed, and can also participate in the consensus process. According to the different degree of blockchain network centralization, three kinds of blockchain under different application scenarios are differentiated:
1. The blockchain with open whole network and no user authorization mechanism is called public chain
2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain
3. All the nodes in the network are in the hands of one organization, which is called private chain
extended data:
function of public chain:
1. Public chain can protect users' rights and interests from the influence of program developers:
in public chain, program developers have no right to interfere with users, so public chain can protect users' rights and interests using the program. In addition, the highly decentralized distributed data storage is also one of the biggest characteristics of the public chain, which has the advantages of openness and transparency of transaction data, and data can not be tampered with, so that the public chain can effectively protect the data security of users
2. Public chain can proce network effect:
an information proct has the inherent need of interconnection, because the purpose of people procing and using them is to better collect and exchange information. With the expansion of the network scale, users can get more value from it and their needs can be met. The common chain is open, so it has the opportunity to be applied by many external users and proce a certain degree of network effect
3. Public chain can be applied to actual business scenarios:
except for financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by public chain on a large scale

at the same time, it can provide mutual trust for transactions by using trusted self-executive code, so as to rece uncertainty and promote digital transfer and asset transactions
bitcoin is the most well-known blockchain as an encryption currency that uses blockchain technology to realize alternative payment. Bitcoin is a kind of unlicensed blockchain, also known as public blockchain, which does not restrict the identity of users who consume bitcoin or participate in verifying the authenticity of transfer blocks in the blockchain (an energy intensive process, also known as "mining"). These miners get token, or bitcoin, in return, and given that everyone can view the block (though anonymously), the blockchain itself is somewhat transparent
bitcoin is controversial and banned by many countries e to user anonymity to a large extent. However, it is worth noting that the anonymity and energy use of bitcoin are its own characteristics, not the characteristics of the whole blockchain technology.
China Gold Coin Corporation, established in 1987, is an enterprise directly under the people's Bank of China. It performs the function of selling precious metal currency. It not only shoulders the task of maintaining and increasing the value of state-owned assets, but also bears the responsibilities of the central bank's credibility, social responsibility and inheriting China's long-standing coin culture
if there is a digital currency trading platform, the rules for launching the platform are made by themselves. This platform is not well-known and has never been heard of in the circle. There are still some well-known digital currency projects in China, such as Ruitai coin, Qianjin card, Weimeng coin, and Weitou movie coin. Now, there are more equity crowdfunding projects using digital currency.
