TrustLayer vs Gitcoin Passport

Living reputation, not a checklist of stamps.

Gitcoin Passport aggregates static stamps from third-party services into a Sybil score. TrustLayer Protocol builds a continuously evolving trust score from real peer signing, usage signals, and on-chain proofs — anchored daily via Merkle roots.
