Quick Start

How does BAS work​

On BAS, firstly user should register a schema in Schema Registry Contract. Schema defines a data structure including fields revokable and resolver.

Then you can create an on-chain attestation based on one schema. And if the resolver field of the schema your attestation related to if not null, the BAS contract will call the resolver and check the validity of the attestation. After passing the verification, the new created attesetation would be recorded in BAS contract.

Or you can create an off-chain attestation and store it in greenfield or any other storage. Then

Either on-chain or off-chain attestation could be claimed as invalid by the attestor through revoking it.
