Condition Validation Decision System for High-Speed Agreements in Decision Making through Agreement in Blockchain

摘要

The present invention relates to a condition verification decision-making system for high-speed consensus processing when making a decision through consensus in a block chain that verifies the contents through consensus in the block chain and enables high-speed decision-making. A blockchain network composed of multiple peers, each peer having a blockchain ledger that records transaction messages in blocks, and a blockchain network that synchronizes the blockchain ledgers of all peers; Generates an asymmetric key that decrypts or encrypts the voting key, encrypts the voting key with the encryption key of the asymmetric key, extracts a combination of users that satisfy the voting condition, and combines the user's approval key for each extracted combination a key management terminal for generating an encrypted decryption key of each combination by encrypting the decryption key of the asymmetric key; A message requesting decision making is recorded in the block chain network, the approval message recorded in the block chain network is collected, the encryption key is released by combining the approval key included in the approval message, and the encrypted decryption key is encrypted It includes a voting terminal for obtaining a voting key by decrypting the voting key.
