TL;DR
This paper introduces a user-centric identity management system integrated into the Bitcoin blockchain, enabling users to control and coordinate their identities across providers with enhanced security and revocation capabilities.
Contribution
It presents a novel blockchain-based identity management scheme that decentralizes control, allowing users to manage and revoke identities while coordinating across multiple providers.
Findings
Identity management built into Bitcoin blockchain
Users can control and revoke their identities
Supports coordination across multiple identity providers
Abstract
We present an identity management scheme built into the Bitcoin blockchain, allowing for identities that are as indelible as the blockchain itself. Moreover, we take advantage of Bitcoin's decentralized nature to facilitate a shared control between users and identity providers, allowing users to directly manage their own identities, fluidly coordinating identities from different providers, even as identity providers can revoke identities and impose controls.
