ZK Email is a set of open source SDKs, libraries, and protocols (https://prove.email) that support making anonymous proofs of redacted existing emails on chain. This is useful for provenant proofs, by directly verifying SHA-RSA signatures from your emails within ZK. It can be used for proof of twitter account, proof of github contribution, sending money on chain to email addresses, and for decentralized email login -- all of which have open source prototypes now, without centralized attesters (see prove.email for links). Our code, roadmap, and ideas are fully open source at https://github.com/zkemail.
