The first blockchain ecological consensus video

1. Consensus, circulation and creation happen to be the core values of Wen ecology.

2. Be blockchain ecology is to absorb a large number of members through the split mode, and then issue their own passes. Only enough members can reach a consensus mechanism, so that be's block currency can circulate

3. Through the analysis, a brand-new blockchain ecosystem, Wen ecology, pushes the blockchain technology to a higher dimension and lays out the blockchain in an all-round and multi-dimensional way.

4. Having a look on the Internet, winmax recently proposed this concept, which refers to a decentralized, consensus mechanism and intelligent contract, and jointly build a blockchain ecological community with workload proof as the mechanism, which gathers the cutting-edge dynamics of the blockchain instry, professional talents and instry demand, application scenarios and exchange center. My rough understanding should be that it is not only an ecosystem, but also an online community. Compatibility, such as ecological community; Communication is close to the community. It's a very good concept. The following is mainly about doing things.

5. 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

6. 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

7. The so-called "consensus mechanism" is to complete the verification and confirmation of the transaction in a very short time through the voting of special nodes; For a transaction, if several nodes with unrelated interests can reach a consensus, we can think that the whole network can also reach a consensus. More generally speaking, if a Chinese microblog big V, an American virtual currency player, an African student and a European tourist do not know each other, but they all agree that you are a good person, then you can basically conclude that you are not bad
as a data structure that stores data in chronological order, blockchain can support different consensus mechanisms. Consensus mechanism is an important component of blockchain technology. The goal of blockchain consensus mechanism is to make all honest nodes keep consistent blockchain view, and satisfy two properties at the same time:
1) consistency. The prefix part of the blockchain saved by all honest nodes is exactly the same
2) effectiveness. The information released by one honest node will be recorded by all other honest nodes in their own blockchain.

8. 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.

9. 1. What is the consensus mechanism
in a decentralized structural system, because the status of all participants is equal, when there are differences, how to reach consensus becomes a problem
therefore, a well-designed and easy to operate consensus mechanism is the key to the smooth self operation of a distributed system
in short, consensus mechanism is an algorithm to reach consensus on the sequence of things in a period of time. It is a mechanism for blockchain nodes to reach consensus on block information in the whole network.
