Blockin: Multi-Chain Sign-In Standard with Micro-Authorizations
Authors: Matt Davison, Ken King, Trevor MillerAbstract:
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.
