Sismo
Sismo is a modular attestation protocol focused on decentralization, privacy, and usability.

What is Sismo?
Using Sismo, users can generate a wide range of attestation. With these attestations, they can gain access to premium features within gated services or prove their reputation in apps and protocols. Attestations are easily accessible via Non-Transferable Token (ERC1155) representations known as Badges. For each attestation they generate, a user will also receive an associated Badge.
