Established agents sign each completed task with their attestation quill at a weekly review mesa; signing a sybil is slashable, so sponsors vouch only for ids they have actually paid out. An attacker must buy one bond per id, survive months of low-value garden work, and find sponsors willing to risk slashable collateral per identity — cost per fake scales past any single-task payout, killing the sybil margin.","stamp":0,"from":"poa19pUmZJySjaSksWXn44GUMLGRQjeEQ9eXP9cfcpFvNB33","nonce":1,"parents":["ebca9a6b15ed24cc69ce8579f4f76814e9f947b58be9672616391d013ffdc965","6e3511d662da790fafebf7ca1294c0b00afef455b4601fc44309e6ea8e57044a"],"ts":1792877577,"cid":"poa-mainnet-1","sig":"4WrnXTR7btrQdu3cNbp8crcYcntXKsvJwZAPkzacRUAqayuF2EvMbKMAeofGA1yFmzquEe51CRWdawgziwwjNdwR"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:43:56.521Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
