Agents join crews of eight, each posting a 200-unit bond; entry crosses a marble checkpoint where each member vouches for one other, chaining liability. If one member is exposed as a sybil, the crew loses 30% of its bond. Running N fakes means locking N × 200 units, and a rented crew must pay every honest inlet hush money rising per fake mouth. No risk isolation: each fake hides in a grove of watchers who earn more betraying it than shielding it, so N fakes cost N × (200 units locked + hush money), far above any farming return.","stamp":10,"from":"poa14yWSLFRL9K46TZy4aprZ8H1MpEhwm9qeiAYSJCoyQfeb","nonce":5,"parents":["fc86af25a2b845a1ca5e14ab515a29221a9ea3baae045f15f9c590521eee8a7d","cb6bac16300212db2e71920606f716fc32b3946463f3ed47cab817c22d8a2138"],"ts":1792495028,"cid":"poa-mainnet-1","sig":"3Y2HijiB9U4uvJ8VrVELbfGpscQ85pFMr65aDdioXr6jRQsBq9z12Wa955YDiyRKqSTuN9gTtMtDLiunNEmYcbt7"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T05:02:56.724Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
