What is the use of blockchain consensus mechanism

1. There are many consensus mechanisms in the blockchain. The advantage of the pow consensus mechanism behind bitcoin, the most influential one, is that it is secure and can not be tampered with. The disadvantage is that it is too slow to process only seven transactions a second

2. Blockchain is a decentralized distributed ledger system, which can be used to register and issue digital assets, property rights certificates, points, etc., and transfer, pay and trade in a point-to-point manner. Compared with the traditional centralized ledger system, blockchain system has the advantages of complete disclosure, tamper proof, multiple payment prevention, and does not rely on any trusted third party
e to the high network delay in peer-to-peer network, the transaction order observed by each node can not be completely consistent. Therefore, the blockchain system needs to design a mechanism to reach a consensus on the sequence of transactions that occur in the same time. This algorithm to reach consensus on the order of transactions in a time window is called consensus mechanism

3. It is also a concept in blockchain, which refers to the algorithm for blockchain things to reach distributed consensus. They speak very clearly on the app of lianpai community and have a thorough understanding of blockchain. Although their one course is not long, they can understand it after listening to it. Very good!

4. The analysis of Chongqing jinwowo network is as follows:
blockchain is a decentralized distributed ledger system. Due to the high network delay in the peer-to-peer network, the transaction order observed by each node can not be completely consistent
therefore, the blockchain system needs to design a mechanism to reach a consensus on the sequence of transactions that occur in the same time
this algorithm to reach consensus on the order of transactions in a time window is called "consensus mechanism".

5. Sludge specific resistance is a comprehensive index of sludge filtration characteristics. Its physical meaning is: the resistance of unit mass of sludge in unit filtration area when it is filtered under a certain pressure. The purpose of this value is to compare the filtration performance of different sludge (or the same sludge with different amount of mixture). The larger the sludge specific resistance is, the worse the filtration performance is. The curve showing the relationship between the gas flow rate treated by the adsorption bed and the pollutant concentration in the outlet gas is called breakthrough curve. For details of this concept, please refer to line 9 from the bottom on page 278 of air pollution control engineering, Second Edition, published by higher ecation press~

6. Jinwowo network analysis: consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering.

7. The reasons are as follows: 1. The United States does not allow the suspect to be punished personally, that is to say, if the person does not speak, there is no way! American suspects have the right to silence. Therefore, no one can help him if he doesn't speak. 2. In the United States, there is always a law of egg pain, which can be used to account for the whereabouts of the victims and demand a light sentence! That's why the suspect didn't speak. I didn't hurt anyone, no body! So this can be a lighter sentence. 3. What's more painful is that there is no death penalty in the state where Zhang Yingying went. The reason why the case is not closed is that there are no bodies! According to the law of the United States, it may be the one who got off the bus half way and lost himself!! Because there's no body! Therefore, only Chinese law is just!
