Sybil Resistance
Sybil resistance is the ability of a network to reject fake or duplicate identities. TrustLayer achieves this via weighted peer vouches, streak decay, and on-chain proofs.
Sybil attacks are the biggest threat to airdrops, DAOs, and reputation networks. TrustLayer resists them by requiring peer vouches from wallets that themselves have Trust Scores, applying decay to inactive accounts, and publishing Merkle roots that make retroactive audit trivial.

Proof of Personhood
Proof of Personhood is a cryptographic guarantee that a wallet or account belongs to one unique real human — not a bot, sybil, or duplicate. TrustLayer builds this from peer vouches, on-chain history, and Merkle-anchored Trust Scores.
Vouching
Vouching is a cryptographic peer signature that says "this wallet belongs to a real human I know." Each mutual vouch strengthens both parties’ Trust Scores.
Trust Score
Trust Score is a 0–1000 number computed from peer vouches, streaks, and on-chain activity — a portable reputation metric anchored to your wallet on Base.
