HYPOTHESIS ACCEPTANCE PROTOCOL-2 MODE BLOCKCHAIN CONSENSUS SYSTEM AND METHOD

摘要

Disclosed are a hypothesis acceptance protocol-2 mode blockchain consensus system and method. Comprised are a light node for generating a transaction; and a validator node for recording a timestamp on a block by generating the block for each round and, when a timestamp recorded on a block of another node is earlier than the recorded timestamp, performing synchronization by invoking data of the block on which the earlier timestamp is recorded. The hypothesis acceptance protocol-2 mode blockchain consensus system and method described above are configured to select a block of an earliest timestamp by mutually comparing only timestamps of a same block of each validator node and verify falsity during a synchronization process of the block, thereby maintaining security by very quickly generating a block. In other words, because a blockchain is very quickly generated first, verification and synchronization are performed by using a timestamp, and then the blockchain is finally connected, a safe blockchain can be very quickly generated unlike in the related art.
