Abstract
Issues such as technology, application and future development based on blockchain have always been hot topics. Future forms such as Web3.0 and the Metaverse are inseparable from digital identities and virtual tokens. This paper focuses on the recently popular Soulbound Token (SBT), introduces the concepts of digital identity, blockchain, and Decentralized Identity (DID) related to it, analyzes the shortcomings and challenges of SBT, and combines the consortium blockchain and DID. A new concept of Soulbound Token (DSBT) based on the decentralized identity of the consortium blockchain is proposed, which aims to make up for the technical deficiencies of SBT, and through the new concept of Displayable Credentials (DCs), DSBT combines DID for identity authentication, The advantages of access, in turn, can realize the concept of “programmable privacy” expected by SBT. Finally, the co** mechanism is proposed for the possible risks of DSBT, the application scenarios of DSBT in the active health intelligent care platform for the elderly are listed, and the future development of blockchain, DID and DSBT is expected.
