Sismo

Sismo enables users to aggregate their digital identities and selectively reveal data derived from their web2 or web3 accounts.

Users aggregate their identity in Sismo’s Data Vault and start accumulating Data Gems—atomic pieces of data that categorize users into groups. In turn, users can generate proofs to make claims about their data (e.g, I own a specific NFT). These proofs are verified by applications—either 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.
