What is bitcoin public chain

1. Let's talk about the social or economic significance of blockchain. In fact, many of the previous technologies were devoted to "proctivity". For example, artificial intelligence is a kind of progress in proctivity. The blockchain, which has greatly improved the proction relations, is committed to the proction relations. So why do you say that
because the so-called proction relationship is actually how to do business between people and business partners. And these things, originally, are in the cognitive process between people, and there is no special program to program or quantify it
for example, if you and I are good friends now, we can do business. If someone stirs up our relationship and we are not good friends, we will not do business. Even if we can make money in business, we will not do business because there is no trust between us
as for blockchain, it is actually because the data is authenticated by all nodes and backed up at the same time, so my data is as real as possible and can't be tampered with. In this case, if you believe my data, you can make a program on this basis, and then use the data to make what kind of business contract, what kind of service, what kind of service, and what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, etc This "proction relationship" of commercial cooperation is programmed. In this way, we believe in the data and the program compiled by the algorithm. Because you believe in the data and the program, you can develop all kinds of apps in the program. These apps are the proction relations and what business to do. This is: blockchain is actually a reconstruction of "proction relationship".

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:

according to the different degree of blockchain network centralization, three different application scenarios of blockchain are differentiated:

(1) the blockchain which is open in the whole network and without user authorization mechanism is called public chain

(2) authorized nodes are allowed to join the network, and information can be viewed according to their permissions. It is often used in inter agency blockchain, which is called alliance chain or instry chain

(3) all nodes in the network are in the hands of one organization, which is called private chain

alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain

4. Bitcoin market can now be seen on professional software, such as the coin card I use now. I think it's very good. Most of the data are available and updated in a timely manner. I recommend you to download and use it
