Ecosystem comparisons
Sybil resistance and identity protocols, compared attribute by attribute
Every comparison below is generated from one shared registry of published protocol behaviour — proof method, biometrics, KYC, key custody, reputation model, token and revocation control. Same fields for every protocol, so the tables are directly comparable.
Ecosystem openness matrix
The matrix scores what a protocol asks of a user and how much of the result stays verifiable in public. It is not a quality, security or market ranking, and it is not derived from TrustLayer trust scores.
