Blockin: Multi-Chain Sign-In Standard with Micro-Authorizations
Abstract
The tech industry is currently making the transition from Web 2.0 to Web 3.0, and with this transition, authentication and authorization have been reimag- ined. Users can now sign in to websites with their unique public/private key pair rather than generating a username and password for every site. How- ever, many useful features, like role-based access control, dynamic resource owner privileges, and expiration tokens, currently don’t have efficient Web 3.0 solutions. Our solution aims to provide a flexible foundation for resource providers to implement the aforementioned features on any blockchain through a two-step process. The first step, authorization, creates an on-chain asset which is to be presented as an access token when interacting with a resource. The second step, authentication, verifies ownership of an asset through querying the blockchain and cryptographic digital signatures. Our solution also aims to be a multi-chain standard, whereas current Web 3.0 sign-in standards are limited to a single blockchain.
