4P Super App: Email

On-chain email with specific Web3 characteristics; 100% self-custodial, encrypted, immutable, permissionless, and data mining resistant.

Based on the OCC Protocol v.1 [Mail] smart contract, OCC SDKs, and white-label framework, 4P App aims to be one of the first community-based integrators of this new on-chain communication technology offering truly advanced Web3-based email features.

Phases within the 4P Email;

(1) to enable end-to-end encryption, both sender and receiver need to install and run “Encryptor Extension”; (2) email's are encrypted with AES while ECDH key agreement protocol is used for generating the secret key (i.e. used in AES encryption); (3) all encrypted attachments are stored on decentralized storage via PollinationX; (4) JSON metadata file is created that includes sender and recipient details, email subject, content, and attachment details (i.e. name, stored location, and checksum); (5) JSON metadata file is encrypted with AES encryption and stored on decentralized storage via PollinationX; (6) JSON metadata file URL and checksum are sent to L1 or L2 [Mails] smart contract; (7) after transaction finality, the receiver loads and decrypts a JSON metadata file and loads and decrypts all the attachments.

Explainer: Composed of; (1) subject; (2) content, and; (3) attachment, the dMail can be from a few kilobytes to gigabytes in size (i.e. attachment size is limited to a PX storage NFT size, the bigger the NFT, the bigger the storage availability).
