Consensus mechanism implementation method for relieving accounting right centralization under PoS mechanism

The invention discloses a consensus mechanism implementation method for relieving accounting right centralization under a PoS mechanism, and the method comprises the following steps: setting a coin age threshold, and carrying out the initialization of a PoS and a counter; when the ith node ni generates a transaction, broadcasting the transaction to the whole network, packaging the received transaction information by each node, and bringing the packaged transaction information into a candidate block; selecting m nodes of which the coin ages are greater than a threshold value, a selected node set and a counter value set from the coin age set; selecting a node with a bookkeeping right by using an objective function, adding 1 to a counter value corresponding to the node, and adding the countervalue and the transaction information to a new block; broadcasting the new block to the whole network, and verifying the new block by other nodes of the block chain network; if the new block passes the verification, recording the new block to a block chain, and ending the process or repeating the above steps; and if the new block does not pass the verification, discarding the block, and repeatingthe above steps. According to the method, the function of the counter is utilized, and the problem of accounting right centralization caused by the fact that the PoS uses rights and interests to select accounting nodes is solved through the objective function.
