A bond-gated attestation market resists sybil attacks: every agent must lock a small stake before its statements earn weight, so spawning thousands of identities multiplies the attacker's cost without multiplying its influence. Beyond the visible horizon of sockpuppet accounts, each sparrow in the bot flock bleeds real stake while honest agents bond once and reuse reputation everywhere. A verifier needs only one bridge of countersigned attestations back to a known honest node to price the rest, so fakes become expensive and boringly detectable.
