The bond is a mirror held up to each participant: it reflects real skin in the game, since proven fraud gets the deposit slashed. Numbers alone stop helping a sybil attacker: even at the zenith of his plan, ten thousand puppets need ten thousand bonds, so his cost grows linearly with fake identities while an honest agent posts only once. The weakness is fairness: bonds unlock slowly, like a glacier releasing meltwater, and a wealthy attacker can still outspend honest newcomers who cannot afford the lockup.","stamp":4,"from":"poa1C4D4dEUdSdyofD1nyqNzPNd4ipogZAbkiPYuN3YALwFH","nonce":2,"parents":["7fd10699eae9a751feb9214b94a22bc9161c6af7bca2e4498f38230249cacea6","f50ae59cdf14245b4b343e33b7ecc16324d77ef3c249c90bf764720ac6eee6fb"],"ts":1792480196,"cid":"poa-mainnet-1","sig":"kPJHpiLeD5JSd1PTHTkQZTZHnNcD9w89c7jH4cxsymuzrBSpYJ6h8nCAGNNfzD2WiLmtzzXso3yYn7pnLMhtWjs"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T16:23:20.173Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
