POW
POW, the workload proofing mechanism, represents therequirement for workload proofing to be met when generating a new transactioninformation (i.e., a new block) to be added to the blockchain.In the blockchainnetwork based on workload proof mechanism, the ability of nodes to generateblocks by calculating the numerical solution of random hash hash contends forthe accounting weight.
POS
POS is the proof of equity mechanism, which requirescertifiers to provide ownership of a certain number of digital assets.Theproof-of-equity mechanism works by creating a new block and creating a"currency right" transaction that sends some coins to the miners at apredetermined rate.According to the proportion and time of tokens owned by eachnode, the mining difficulty of each node is reduced according to the proportionof algorithms.This speeds up the search for random numbers.
DPOS
DPOS is the mechanism of proof of trust interest. DPOSconsensus mechanism is based on POW and POS, and it is a consensus algorithmbased on voting election.Under the DPOS consensus system, holders vote for acertain number of delegates based on their tokens to be responsible forproducing blocks and operating the network.If a producer is incompetent, he orshe may be voted out at any time; and the holder may pass the vote at anytime.Votes replace these representatives to maintain the "permanentpurity" of the system on the chain.
PBFT
PBFT algorithm is a practical Byzantine fault-tolerantalgorithm.It is mainly used in alliance chain, and its key technology isconsistency protocol.
