Sismo is a modular attestation protocol that oversees the issuance of ZK Badges (non-transferable tokens or SBTs). We were recently featured in a list of Vitalik Buterin’s most exciting projects. We stand at the crossroads of zero-knowledge proofs, digital identity, and web3 social.
ZK Badges issued by the Sismo protocol are privacy-preserving tokenized attestations. They allow users to leverage social capital from imported web2 and web3 accounts—ensuring they can selectively reveal facts about their identities to access particular applications or services. Picture a Proof of Contributions ZK Badge that does not reveal the exact contributor or an Ethereum Twitter Influencer ZK Badge that does not reveal the exact Twitter account.
As ZK Badges are tokens adhering to the ERC1155 standard, they can be integrated into any application (web2 or web3) as an access control and reputation curation tool.
Our tightknit team of crypto natives has been working on Ethereum since 2015 (ex Aave, EthCC, Kleros, ConsensSys). To realize our vision, we raised $10,000,000 from some of the biggest names in crypto (angels from Lens, Optimism, Starkware, the Ethereum Foundation, Curve, Aave, Snapshot, Guild, and top VCs like Framework, Delphi, IDEO or Seedclub Ventures).
