What are the advantages of consensus mechanism in blockchain

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. How to reach a consensus on decentralized networks
in the blockchain system, there is no centralized bookkeeping institution like a bank, so it is very important to ensure the consistency of each transaction on all bookkeeping nodes, that is, to make the whole network reach a consensus. The consensus mechanism solves this problem
at present, the main consensus mechanisms are workload proof mechanism POW and equity proof mechanism POS
POW determines your chances of getting bookkeeping rights by evaluating your workload. The greater the workload, the more likely you will get this bookkeeping opportunity
POS determines your chances of getting bookkeeping rights by evaluating the number and ration of tokens you hold. This is similar to the stock dividend system, holding a relatively large number of shares can get more dividends
the principle of dpos is similar to that of POS, except that some "deputies to the National People's Congress" are selected. The main difference from POS is that the node elects several agents, which are verified and recorded by the agents
with the development of technology, more advanced consensus mechanisms may emerge in the future.

3. 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".

4. 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~

5. 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.

6. 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!

7. Jinwowo uses a vivid metaphor to illustrate: if consensus is the basis of blockchain, then consensus mechanism is the soul of blockchain
when explaining what a blockchain is, we can use a simple and clear decentralized distributed ledger to summarize it. However, in this ledger, how to sort the things generated in almost the same time is related to the consensus mechanism of the blockchain network
therefore, jinwowo network technology believes that consensus mechanism is an algorithm to reach consensus on the sequence of things in a period of time.
