System Architecture

PRIV8 is built on a modular, privacy-first system architecture that enforces cryptographic isolation, stateless operation, and zero data persistence across all communication layers. User identity is established through wallet-based authentication, where Ed25519 keypairs are used exclusively for session authorization and cryptographic signatures, not for payload encryption. Message content is encrypted locally using ephemeral session keys derived through the DWK-Lock protocol, ensuring that private keys never function as direct encryption material. All cryptographic processes occur client-side, eliminating the need for credential storage, message recovery mechanisms, or centralized trust assumptions.

The Solana network serves as an identity verification and access control layer rather than a message transport or storage medium. Gateway nodes validate wallet signatures to authorize communication sessions without recording message content, routing paths, or metadata. Messages and files are transmitted through transient channels and exist only in volatile memory during active delivery. Once a message is successfully received or a chat session ends, all associated data is permanently destroyed. This architecture ensures that neither historical reconstruction nor retrospective forensic analysis is possible, even in the event of partial network compromise.
