Several consensus mechanisms of blockchain
Publish: 2021-05-12 18:51:44
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. 1. Pow (proof of work) workload proof
one sentence introction: the more you do, the more you get
2. POS proof of stake
in a word: the more you hold, the more you get< Pbft: practical Byzantine fault tolerance
3. Pbft: practical Byzantine fault tolerance
Introction: it provides (n-1) / 3 fault tolerance on the premise of ensuring the activity and safety< Dbft: Byzantine fault tolerant algorithm authorized by delegated BFT
Introction: dbft mechanism adopted by ant is that bookkeepers are selected by rights and interests, and then bookkeepers reach a consensus through Byzantine fault tolerant algorithm
5. Pool verification pool
is based on traditional distributed consistency technology and data verification mechanism
chainnova is a blockchain company. I feel it's very good. Although I don't know any hash algorithm, I still know a little bit.

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. POW: proof of work (POW), a simple explanation is a proof to confirm that you have done a certain amount of work. Because the whole process of monitoring work is usually extremely inefficient, and it is a very efficient way to prove that the corresponding workload has been completed through the certification of the work results. For example, in real life, graation certificate, driver's license and so on, are obtained by means of test results. That is to say, how much money you get depends on your effective contribution to mining. Simply understand, the better your computer performance, the more revenue you will get. This is to allocate money according to your workload. Most digital currencies, such as bitcoin, lightcoin, etc., are virtual currencies based on POW mode (the higher the computing power, the longer the mining time, the more coins you get)
pos: POS is a consensus algorithm in the public chain, which can be used as a replacement of pow algorithm. POW is a mechanism to ensure the security of bitcoin, Ethereum and many other blockchains, but POW algorithm is criticized for destroying the environment and wasting power in the process of mining. POS tries to solve these problems by replacing the concept of mining with a different mechanism
POS mechanism can be described as a kind of virtual mining. POS mainly relies on the token in the blockchain itself. In pow, a user may buy a computer for 1000 dollars, join the network to mine and proce new blocks, and get a reward. In POS, users can buy tokens of equal value with us $1000 and put them into the POS mechanism as deposit, so that users have the opportunity to generate new blocks and get rewards. In pow, if users spend $2000 on hardware equipment, they will of course get twice the computing power to mine, thus getting twice the reward. Similarly, if you invest twice as much token as the deposit in the POS mechanism, you have twice as much chance to get the right to generate new blocks.

5. 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.

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. I just came into contact with this project recently. I hope it can help you
FST network is a blockchain application technology service platform, which is committed to further application of blockchain. Its pillar proct FST network engine mole is an infrastructure built for enterprises to save development time. The FST network engine mole, through comprehensive molar logic construction, allows anyone to manage the certificate business without coding environment, reces the threshold of the blockchain development community, and saves the development cycle.

8. The general itinerary of the group period is as follows:
Pattaya—— One day tour of Shami Island—— Pattaya & Chen 134; Location of Du Lala's promotion; Thai massage
after breakfast, drive to the [Shami Island National Marine Nature Reserve scenic area] of Luo Yong mansion to launch a wonderful one-day tour of Shami island. Take a boat to sea, and the sea and sky are the same. You will be intoxicated with the embrace of nature. The blue sky and green sea are accompanied by the boundless coast, and the waves and bubbles rush to the beach. We have prepared beach reclining chairs for you. You can change into the most beautiful swimsuit, enjoy the embrace of the sea, sunbathe, blow the sea breeze, enjoy the leisurely island scenery, relax yourself, forget all the worldly noise, and enjoy the rare holiday from this paradise. At noon, you can enjoy the fresh seafood on the island. The original flavor will make you have endless aftertaste. In the afternoon, take a speedboat back to enjoy the world-famous night city of Pattaya. Before dark, we can also visit the water town of Sihe Town, the newly developed and most popular location of Du Lala's promotion. There are a variety of unique local procts in the water market, which will make you happy. Then arrange the ancient Thai massage. The ancient Thai massage is similar to the traditional Chinese massage. Regular massage of acupoints can also relax the muscles and activate the collaterals. Specially arrange a 1-hour course of treatment to make you healthy and refreshing.
