Ethereum Attestation Service

Ethereum Attestation Service (EAS) is a public good that allows anyone to create and validate on-chain and off-chain attestations of any type. It enables registering a schema about any topic and making attestations using that schema. The goal is to create a universal, open-source layer of attestations that can be used by a variety of applications and protocols to verify the authenticity and integrity of data across different systems and communities.
