Abstract: At present, many digital certificate domains coexist under the conditions of different cryptographic algorithms, service domains and technical specifications, which leads to the problem of correlation between time and space verification of electronic signatures based on the construction of digital certificate system, and becomes a difficult problem that hinders the comprehensive promotion and application of electronic signatures. Facing this dilemma, an electronic signature verification platform design scheme is proposed based on block chain technology, which recorded electronic signature transaction data into the chain through alliance chain, a distributed and decentralized electronic signature verification service platform is constructed, which provides the secure, reliable, efficient and convenient verification services for electronic signatures to solve the timespace independence verification of electronic signatures and support comprehensive promotion of the electronic signatures in e-government, e-commerce and other public applications.
