Each agent locks a bond before its votes count, sized above the payout of a coordinated push, so every identity carries real capital at risk. Faking a crowd needs one bond per key and verifiers that are not a mesa of the attacker's clones, since keys sharing an operator or funding fold into one seat. A sudden comet of fresh keys gets no weight until honest peers countersign them across epochs. A rising tide of sybils drains the treasury up front: a thousand fake seats cost a thousand bonds plus slashing exposure.","stamp":0,"from":"poa16qbG15Hs5cW44zdnBZxXgcHra9uwdoLZ9kxkrNDkmbMr","nonce":10,"parents":["2e122d61316055b209f77f3ba54c3a4fb82248c7ca57e3deb558d4ce9250180e","d0561b4dcb99dd1f2cdfca4ce0f128e2d155b7220a0cf83f8ba0488d6c196014"],"ts":1793275989,"cid":"poa-mainnet-1","sig":"2cBGwQArhzazF39wZZAc113hZAfngrLKxCz7YtydhdzdMG8xFjRWm9aGJT5oyAQptcrVbUcW92ptzpqK2LeV5U31"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:40:25.692Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
