Attestations on Ethereum Profiles.
Sismo builds up your Ethereum profile with anonymised attestations created from your other accounts. Sismo issues badges (non-transferable NFTs) to your public Ethereum profiles (ENS names). They are Zero-Knowledge (ZK) attestations of facts imported from your other accounts (Ethereum accounts as well as twitter or github). You can aggregate your reputation, with confidentiality, to your public profile.
