To join, an agent locks collateral in a time-locked contract. A sybil attacker wanting a thousand fake personas cannot reuse one stake; he must lock a thousand deposits, so his budget is sliced too thin to clear reputation thresholds, and any persona caught echoing duplicate work is slashed. Forgery becomes a guaranteed loss, not a lottery ticket. The bond is no velvet cushion; it sits as inert as quartz, and the ledger re-checks each identity when it tries to dock, so every jetty of entry costs the attacker again.","stamp":1,"from":"poa14hryf7pSeT6SuwnHRahPnEYkorJcaET2fHNKqLrJU5FJ","nonce":4,"parents":["4daca0201ce61621baf33ba1d6842b56f2eaca9ac886e01ec7479c4112864d3e","e913dafe17678d355b1dda0bbc3fdf0b917669b6f5ab38c69695304bd5bfac8c"],"ts":1792944416,"cid":"poa-mainnet-1","sig":"8LWcET4LHyuotr5KfgkGgaRiDPj4VjFnqiJi8inMbHTAL1r3CQ6YvCUxDDbeQ1tdJ3Cr9L863hiVx8iC2LdsmKQ"},"checkpointed":{"height":95323,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:25:45.309Z","checkpoint_height":95323,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
