TrustLayer is the decentralized human trust layer for Web3 — a Base-native protocol that publishes portable, sybil-resistant Trust Scores derived from peer vouches and on-chain proofs. Any dApp can verify a user is a real human in a single Solidity call, without KYC or biometrics.

Yes. Creating a Trust ID, vouching peers, and earning $TRUST rewards is free. Only optional premium tiers or write operations charge $TRUST fees.

Does TrustLayer require KYC or biometrics?

No. TrustLayer never collects KYC, iris scans, or personal data. Identity comes from peer vouches and wallet signatures — reputation is math, not documents.

What is the $TRUST token?

$TRUST is TrustLayer's native token on Base with a fixed 1B supply. It powers vouching rewards, badge fees, staking gates, and revenue-funded buyback-and-burn.

How does TrustLayer compare to Worldcoin?

TrustLayer requires no biometric hardware, is fully non-custodial, and lives on Base. Worldcoin uses iris scans and centralized orb hardware. See the full comparison at /vs/worldcoin.

Proof of Humanity vs TrustLayer Protocol

Proof of Humanity (video registry with crypto-economic challenges) and TrustLayer Protocol (peer-vouched human trust scores on base) both aim at sybil resistance, but they disagree on 5 of 12 measurable attributes. This page compares them field by field from published protocol behaviour — no marketing scores, no invented metrics.

Proof of Humanity

Proof of Humanity trades privacy for adversarial auditability: registrations are public videos anyone can challenge with a deposit. Sybil resistance is enforced economically.

Openness 9/10

TrustLayer Protocol

TrustLayer issues a device-held identity from a wallet signature, then grows a continuous trust score from independent peer vouches and recorded proofs. Scores, badges and audit reports are public and queryable over an open API.

Openness 10/10

Best fit for Proof of Humanity

Governance systems that want an adversarial, publicly auditable registry
Communities comfortable with public video identity

Best fit for TrustLayer Protocol

Apps that need sybil resistance today with no hardware rollout
Communities building peer-to-peer reputation
Teams that cannot collect KYC or biometric data

Verdict

On the openness criteria below, TrustLayer Protocol scores 10/10 and Proof of Humanity scores 9/10 — 5 of 12 attributes differ. TrustLayer Protocol asks less of the user up front; Proof of Humanity offers a stronger external anchor where its trust assumptions are acceptable. Pick by what you must not collect, and by whether you need a one-off human check or a score that keeps moving.

Frequently asked questions

What is the main difference between Proof of Humanity and TrustLayer Protocol?▼

Network: Proof of Humanity — Ethereum / Gnosis; TrustLayer Protocol — Base (EVM).

Does Proof of Humanity or TrustLayer Protocol require biometrics or KYC?▼

Proof of Humanity: none collected, no kyc. TrustLayer Protocol: none collected, no kyc.

Which one can a developer query from an API?▼

Proof of Humanity and TrustLayer Protocol

Can Proof of Humanity and TrustLayer Protocol be used together?▼

Yes. They produce independent signals, so apps commonly combine a personhood check with a continuous reputation score before granting access or rewards.
