The invention discloses a traceable digital currency transaction system based on a block chain. The traceable digital currency transaction system comprises a certificate application module used for generating corresponding parameters and public and private keys by a certificate authentication mechanism and a transaction sending node; The certificate issuing module is used for signing the public key of the transaction sending node by the certificate authentication mechanism to generate a certificate of the transaction sending node; The certificate randomization module is used for randomizing the certificate obtained by the terminal equipment by the transaction sending node and sending the randomized certificate to the remote verification terminal; The digital currency transaction module isused for carrying out block chain-based digital currency transaction among the transaction sending node, the miner node and the transaction receiving node; And the user identity tracking module is used for tracking the identity of the transaction sending node by the certificate authentication mechanism. According to the system, the existing PKI system and the existing digital currency transactionsystem are combined, so that the system has a good cross-platform characteristic, the expandability of the system is enhanced, and the anonymity and traceability of terminal equipment are guaranteed.
Description
technical field [0001] The invention relates to the technical field of block chain and digital currency, in particular to a traceable digital currency transaction system based on block chain. Background technique [0002] In recent years, the innovative development of information technology, mobile Internet technology and cloud computing technology is profoundly changing people's payment methods. The birth and circulation of blockchain-based digital currency represented by Bitcoin marks the acceleration of the Internet characterized by information generation and flow into a new era of value Internet characterized by value generation and transfer. Digital currency with the characteristics of decentralization and unforgeability can eliminate the cost of traditional currency design, printing and escort storage, reduce cross-regional and cross-institutional capital circulation barriers, improve the convenience and transparency of transaction activities, and adapt to modernizatio...
