The invention discloses a digital currency multi-signature method and system based on a block chain, and electronic equipment. The method comprises the following steps: creating a multi-signature wallet on a block chain to obtain the number of nodes of a plurality of participants; equally dividing the set passwords into the same number, and when the multi-signature wallet receives an account fund change request, obtaining password strings input by a plurality of nodes; and controlling the account fund change of the multi-signature wallet is controlled through the matching verification of the plurality of password strings and the complete password and the multi-signature number verification. According to the method, dependence on a node address and a private key during multi-signature of existing digital currencies can be avoided, and more types of digital currencies can be circulated on the block chain in a multi-signature mode; the method is especially suitable for the legal digital currency under the management and control of a central bank, avoids the steps of obtaining the node address and the private key of the legal digital currency to perform key segmentation and recovery under the multi-signature step based on the method, and guarantees the circulation safety of the legal digital currency on the block chain.
Description
technical field [0001] The present invention relates to the field of digital currency multi-signature methods, in particular to a blockchain-based digital currency multi-signature method, system and electronic equipment. Background technique [0002] Digital currency is a legal currency represented by a series of strings, and the security of digital currency is protected by cryptographic algorithms. As a digital form of RMB, the legal digital currency can be issued by the central bank or authorized by the central bank, and the designated operating agency participates in the operation and exchange to the public. Based on the generalized account system, it supports the loose coupling function of bank accounts, and paper It is a controllable and anonymous payment tool that is equivalent to banknotes and coins, and has value characteristics and legal compensation. [0003] The multi-signature of traditional digital currency (Bitcoin, Litecoin, etc.) requires the authorization o...
