LinkDID: A Privacy-Preserving, Sybil-Resistant and Key-Recoverable Decentralized Identity Scheme. (arXiv:2307.14679v1 [cs.CR])

Decentralized identity mechanisms endeavor to endow users with complete
sovereignty over their digital assets within the Web3 ecosystem. Unfortunately,
this benefit frequently comes at the expense of users' credential and identity
privacy. Additionally, existing schemes fail to resist Sybil attacks that have
long plagued Web3, and lack reasonable key recovery mechanisms to regain
control of digital assets after loss. In this work, we propose LinkDID, a
privacy-preserving, Sybil-resistant, and key-recoverable decentralized identity
scheme that supports selective disclosure of credentials for …
