CMS: A Consortium Management Solution for Decentralized Identifier Resolution

Abstract

As blockchain and distributed ledger technologies continue to evolve, the management of digital identity ownership and its security have increasingly come under scrutiny. The advent of decentralized identity (DID) technologies aims to return control of identity to users. However, existing DID resolution schemes often rely on centralized management, which can lead to single points of failure, security vulnerabilities, insufficient scalability, and privacy concerns. To address these challenges, this paper introduces a novel solution named CMS. CMS leverages blockchain smart contracts and InterPlanetary File System (IPFS) decentralized storage to implement a consortium management approach. It drives the management of a universal resolver through a voting mechanism of smart contracts and utilizes IPFS for distributed storage, thereby enhancing system transparency, stability, and the persistent security of data. Although this approach increases the technical complexity of the system and may impact performance, it significantly enhances management transparency and data security.
