SYSTEM FOR PREVENTING COUNTERFEIT OF NON FACE-TO-FACE TRANSACTIONS BASED ON BLOCKCHAIN

摘要

According to the present invention, a blockchain-based system for preventing forgery of a non-face-to-face transaction comprises: a first blockchain network; a second blockchain network; a first intermediary client for obtaining first smart contract information and broadcasting the first smart contract information to the first blockchain network; a second intermediary client for obtaining second smart contract information and broadcasting the second smart contract information to the second blockchain network; and a monitoring node for generating an integrated smart contract code based on the first smart contract information and the second smart contract information, generating an integrated block, and connecting the integrated block to an integrated blockchain.
