Description

Block chain multi-signature management method and device, electronic equipment and readable medium Technical Field The disclosure relates to the technical field of blockchains, in particular to a blockchain multi-signature management method, a device, electronic equipment and a readable medium. Background With the continued development of blockchain technology, federated chains have gained widespread attention in enterprise-level applications as a solution that allows authorized nodes to join a network, forming distributed trust within a particular community. Stable operation of the federated chain relies on an efficient on-chain governance mechanism. In the traditional alliance chain management practice, a centralized management mechanism of a super administrator mode is adopted for improving decision efficiency. Under this mechanism, a single supermanager account is given the highest authority and critical operations including, but not limited to, consensus parameter adjustment, node admission control, etc., can be performed independently. The centralized governance mechanism has inherent design defects that firstly, the authority is excessively centralized to cause the governance centralized risk, secondly, a super administrator account becomes a systematic single point fault source, once the private key is revealed or maliciously attacked, the whole network is subjected to disastrous influence, and furthermore, the trust model of a single entity is relied on to weaken the trust removing property of a alliance chain, so that the trust cost of a participant is increased. To overcome the drawbacks of the supermanager mode, a multiple signature based solution may be employed, i.e. rights management and risk dispersion are achieved by requiring a fixed number of manager (e.g. M-of-N mode) co-authorizers to perform the abatement operations. However, the existing on-chain multi-signature scheme treatment strategy is single in solidification, cannot be dynamically adjusted according to the nature, the influence range and the emergency degree of treatment matters, and is difficult to meet the complex treatment requirements of the alliance chain.
