May I ask, similar to the tendermint, hotstuff and pbft consensus, do they store the verification signature of each verifier on the block, and how? If stored in blocks, the received signatures may not be the same, resulting in inconsistent blocks

Excuse me? , Be similar to tendermint,hotstuff,pbft Consensus , Will the verification signature of each verifier on the block be stored , How to store ? If stored in blocks, the received signatures may not be the same, resulting in inconsistent blocks




Take the answer 1:

Basically, all blockchain consensus agreements , A fundamental problem needs to be solved . Is how to decide who can generate the next block . It can be God's choice , Or take turns , Or vote for , Or randomly . Choose different ways , It corresponds to different characteristics . It also corresponds to different functions , Become different chains . for instance PBFT, Ultimate , It won't fork , It is something that other consensus does not have , The problem is that there is too much news , Access permit requirements , Online rate problem .POW The problem is energy consumption , No finality . however POW A good feature is anti copy . because POW The computational power of is a physical requirement , You cannot copy multiple copies at the same time . about POS Speaking of , It's easy to copy another copy . In this picture , An important information is the number of nodes that different protocols can apply . at present , The number of support nodes is the largest , That is, the most decentralized is POW. Let's look at the last two green agreements , One is RBFT, Inherited BFT The advantages of , It also improves performance , If the random number is random enough . Our hope is to surpass Libra Of Hotstuff agreement . At the system chain level , Can handle pow+pos At the same time . The other is SAV Protocol, This is the development direction of the future Mohist . We hope it can support more than one million nodes , And don't need to consume too much energy .———————————————————————— Looking at the financial standards of the central bank, they all put forward the consensus , Ability to prevent malicious node attacks , The domestic fabric Consensus needs to be bft Transformation can meet the requirements . It seems that there is little understanding of this in the market at present , Or say IBM Too powerful .
