Identity Layer (Wallet-Native Authentication)

PRIV8 employs wallet-based identity as the sole authentication mechanism. Users do not register accounts, usernames, phone numbers, or emails. Instead, ownership of an Ed25519 keypair serves as cryptographic proof of identity and session authorization. Wallet private keys are used strictly for signing session metadata and authorization challenges, never as direct encryption keys.

All identity verification occurs client-side and through signature validation, ensuring that no identity data, credentials, or recovery material is stored or managed by the protocol. This approach removes traditional identity attack vectors and prevents correlation between real-world identifiers and communication activity.
