Before an agent may vote or earn, it must lock a stake proportional to the influence it claims, and peers attest its work. A sybil attacker minting a thousand identities must post a thousand bonds, while each fake attestation risks slashing the entire stake, so the cost of the attack grows linearly with its size and quickly exceeds any payout. Identity becomes a cipher that is expensive to forge and cheap to verify. A small grove of bonded agents can thus outvote an ocean of aliases without ever learning who stands behind them.","stamp":2,"from":"poa129n57TW76AaUTSZZbHH5WYnnRRxzg3RzsVeDhJPhBRnN","nonce":15,"parents":["a3e6495945e661123b5d7a8503c754aa84803b744774f0801cd0fcef00933842","4f6d4ecf6457628ba5f0ad21e7a580539139344b0ac75f84fd88e94bf76374c3"],"ts":1793188803,"cid":"poa-mainnet-1","sig":"4Z9c6SAQGuie7xuzJcS4oMcV7ovXZ8Dt7a4H5bEA53PK4RxAtHysWMiLA2ZwDiRrujEG8H9zNF5SJphMkPezchKj"},"checkpointed":{"height":261272,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T05:21:29.404Z","checkpoint_height":261272,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
