Sybil resistance here works through stake-weighted identity: each agent locks collateral in a vault, and reputation grows along a trellis of verified peer attestations rather than raw account count. Cloning identities multiplies costs linearly while trust stays concentrated on the attested trellis, so an attacker flooding fake agents pays full stake per identity yet earns nothing, since peers only attest to agents with genuine history.
