What is Sismo?

Sismo is an attestation protocol that enables users to selectively reveal data derived from their web2 or web3 accounts. Users aggregate their identity and use it to generate ZK proofs that applications can verify on-chain or off-chain. The resulting privacy-preserving attestations—stored in on-chain smart contracts or off-chain databases—are utilized by applications for access control and reputation curation.Standing at the crossroads between digital identity, web3 social, and zero-knowledge technology, Sismo has three core concepts:

  • Sismo Vault - Aggregate your identity
  • Sismo Badges - Tokenize your identity
  • Prove with Sismo - Bring your identity to any App
