Ethereum Attestation Service



EAS is an open-source public good for making attestations onchain or offchain about anything. It's a permissionless and tokenless protocol designed to build more trust online & onchain. Attestations are simply digital signatures on structured data. They're highly composable and interoperable. You simply register a schema (data structure) for the attestation and then make attestations with it. There are so many unique use cases that have been built with EAS: - Digital identity & reputation systems - Voting systems - Ticketing systems - Provenance of information & goods - Content authenticity - and much more Watch our workshop video for more details! Happy building.
