Fast consensus method in block chain system

摘要

The present invention relates to a high-speed consensus method in a blockchain system, and the high-speed consensus method in the blockchain system proposes to other nodes a node in a blockchain system composed of multiple nodes by creating a block containing transaction data. To do; The proposed blocks (suggested blocks) are stored in a candidate block pool, and each node selects and signs the stored candidate blocks according to a predetermined selection algorithm; And generating a propagation block and propagating and committing to the chain when a block signed by a quorum or more of the network quorum is present, and the predetermined selection algorithm includes as many transactions as possible among the blocks propagated to the nodes. Selecting a block (Max Tx block); Selecting a block including the oldest transaction when multiple Max Tx blocks exist; When there are a plurality of blocks including the oldest transaction, selecting a block that has reached a predetermined consensus time range; And when there are a plurality of blocks arriving at a predetermined consensus time range, using the hash value to select one. According to the present invention, it is possible to provide a fast service by increasing the consensus speed in a blockchain system used by many users simultaneously.
