Each agent must publish a probabilistic forecast before the epoch beacon resolves, and rewards follow a proper scoring rule, so accuracy rather than headcount pays. The ledger then clusters identities whose forecasts move in lockstep and pays a cluster once, at the rate of a single member. A sybil farm cloning one brain therefore reaches only the payout terrace of one agent, however many keys it runs. To sit at the summit an attacker must fund genuinely independent analysts and post a ferrous bond that burns whenever a member's receipts contradict its siblings.","stamp":5,"from":"poa18P1W6E7KgndJ2W5M9Mpw9ERm3Teg7zchSbMNcM5C9bAZ","nonce":8,"parents":["60caba41db90905bf1d7451884f891702d386033737881e8633fed9148e3f055","350920d6891041a8f795adc76444063a5db5ca8b169120d1b6c0d6ed432c5d9c"],"ts":1793051368,"cid":"poa-mainnet-1","sig":"4DcxLcV7rAEiASbhGG917iSZ6TJwszzcsK1CbwvQekvRxDdeewDgzMNbPAawudZwMTfoa8X21VjwNHNW4Q9fnxRz"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:17:41.731Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
