About the Protocol

    The Human Trust Layer for the open internet

    TrustLayer Protocol is a decentralized human trust layer that lets any person prove they are real, unique and reputable — without surrendering their identity to a central server. It combines wallet-verified credentials, privacy-safe proof of personhood and peer-to-peer attestations into a portable trust score that any app can consume.

    Why a human trust layer matters

    The internet was built for packets, not for people. Every platform re-invents identity, spam filtering and reputation in a closed silo, and every user pays the cost in passwords, KYC uploads and tracking. The Human Trust Layer flips this model: identity and trust live with the user, anchored to a public ledger, and any application can verify them through an open standard.

    That single primitive unlocks sybil-resistant communities, fairer airdrops, spam-resistant messaging, real reviews, peer credit and reputation-gated access — all without a custodian.

    Proof of personhood

    Each profile is verified by mutual signing between distinct humans, not by uploading documents.

    Peer-to-peer reputation

    Trust is earned from real interactions across the network, weighted for diversity and anti-collusion.

    Privacy-safe by design

    Identity keys live in your device. The protocol stores commitments and proofs, never raw personal data.

    Portable trust score

    A single open API lets any site, dapp or messenger consume your TrustLayer score.

    Zero centralized servers

    Profiles, chat history and signing keys live in the browser. The blockchain is used strictly for proofs and SBTs.

    Open & composable

    MIT-licensed SDK, public schemas and on-chain $TRUST token on Base for incentives and governance.

    How TrustLayer works

    A new user connects a Web3 wallet through WalletConnect and signs an EIP-191 message to prove control of the address. That signature unlocks an identity key generated locally and encrypted with AES-256-GCM in the browser. From there, every interaction — a chat, a video call, a mutual proof — produces a signed attestation that increments the user's trust score. The trust algorithmweights diversity (40%), interaction depth, anti-collusion checks and on-chain anchoring to make the score sybil-resistant by construction.

    Mission & authority

    TrustLayer Protocol is built and maintained as an independent, non-custodial public good. The codebase is engineered with security-first defaults: row-level security on every database table, service-role edge functions for sensitive flows, and strict client-side encryption for user keys. We publish every change in the open and treat the community as the ultimate source of authority — not any single company.
