blockchain classification:

1 private chain

refers to the blockchain with certain centralized control. Only the general ledger technology of blockchain is used for bookkeeping. It can be a company or an indivial who enjoys the exclusive write permission of the blockchain. This blockchain is not very different from other distributed storage schemes. The participating nodes are only users themselves, and the access and use of data have strict authority management. Due to the existence of centralized control, alliance chain can also be considered as a private chain

features: because the user has the final say, the data inside can not be changed, and there is not much protection for the third party. Generally used for internal audit. The vice president of fire coin technology believes: there are indeed a large number of scenarios in the private chain that can meet the needs of the real world. Limited decentralization makes it easier to reach a consensus, which can make the transaction faster and more efficient, and can provide more controlled functions. Decentralization is the core value of blockchain technology. If the private chain can not make full use of the decentralized trust base constructed by the public chain in practice, its development space will be limited

2public chain

public blockchain is the earliest blockchain and the most widely used one at present. It refers to a completely decentralized blockchain like bitcoin blockchain, which is not controlled by any organization. Any indivial or group in the world can send a transaction, and the transaction can be effectively confirmed by the blockchain, and anyone can participate in the consensus process. Participants in the consensus process maintain database security through cryptography and built-in economic incentives

features: completely open, uncontrolled, rely on encryption technology to ensure security

3 alliance chain

multiple preselected nodes are designated as bookkeepers within a certain group. The generation of each block is jointly determined by all preselected nodes. Other access nodes can participate in the transaction, but not the bookkeeping process (in essence, it's still managed bookkeeping, but it's just distributed bookkeeping. How many preselected nodes are there, How to decide the bookkeeper of each block becomes the main risk point of the blockchain). Anyone else can make limited query through the open API of the blockchain

the nodes participating in the blockchain are selected in advance, and the nodes are likely to have good network connections. Other consensus algorithms without workload proof can be used on such a blockchain. For example, a blockchain has been established among 100 financial institutions, and more than 67 institutions must agree to reach a consensus

Prospect:

the development of blockchain technology has also brought changes in the operation concepts of various instries. New technologies and new concepts have promoted the new development of various instries. This driving force has a huge impact on society and the promotion of economic activities. Many new instrial phenomena will occur one after another, and the public will wait and see, It is expected that this new technology will be used by all instries and benefit all instries better

4. There should be no problem. Maybe it's the psychological effect. Just have a rest. But it may also be a slight concussion. There's no need to worry about it. Now medicine can cure it by knocking. It's to put a turban around the head, then knock with your hand, drag the cloth, and cure it by shaking. If you really don't feel at ease, go to the hospital and have a check. It's about 30 yuan, I hope I can help you. Best wishes

5. Blockchain is a kind of technology, which can accelerate the instrial upgrading and open up the upstream and downstream of the instry. Anyone can do it.
