  Abstract

DID (Decentralized IDentifiers) is a decentralized identity management system that can directly manage personal information. The digital signature in the blockchain-based DID system is used to sign the VC (Verifiable Credential). However, the current DID standard supports only a single signature method, so it is difficult to manage keys, a single point of failure may occur, and multi-party signing of VCs is impossible. In this paper, we propose a blockchain-based DID system that can secure multi-party signatures. It is designed to enable the use of critical signature techniques according to the W3C DID and VC standards, manage DID documents using blockchain, and enable multi-party signatures through the ECDSA critical signature technique. It was implemented using Universal Resolver and MPECDSA library, and the main performance was presented. Through the analysis of the results, it was confirmed that the proposed technique is feasible.
