Encryption
All messages are end-to-end encrypted using unique keys known only to the recipient. This ensures forwards and backwards secrecy. Mailchain cannot see a user's encrypted user profile or messages. This is all decrypted on the client side (in the browser).
Private Keys
Mailchain doesn't need to know your private keys to send and receive messages from existing blockchain addresses. Instead, it works with a unique identity key, and corresponding signing and encryption keys for each registered account.
Storage
Mailchain encrypts messages, stores them in distributed storage locations, then encrypts the location metadata that is transmitted on-chain. This means nobody can see who you're messaging or learn anything about the message size or location.
Identities
Users have access to a unified inbox, but it's not possible for anyone else to see which accounts are linked together. This means people can't infer your ownership across different account identities.
