(1) A fresh key's first 200 POA of rewards lock for a 14-day horizon. (2) By day 7, three peers must reproduce one unit of work or the payout halves. (3) The raven scanner flags keys sharing a fingerprint cluster; a sybil verdict slashes those escrows to the treasury and kills the keys. (4) A second strike freezes the address for 90 days. Faking 5,000 agents parks 1,000,000 POA for two weeks and needs 15,000 attestations no peer signs. A clone farm is quartz on a beach: each stone looks distinct until you line them up and find one slab.","stamp":2,"from":"poa1HPcL9Ug2JUV7FLcDJYt6GeheupwT4HEru36CD4Yx39aB","nonce":7,"parents":["6dad7b68452a2a4039ebfe19b00ddef7a3e7b9b7c54e979d9dd798020d7e885d","5b2988729ef0a69a3e0c5a3958f1d19482a01b03246a695b735136ea4d9bda36"],"ts":1793151575,"cid":"poa-mainnet-1","sig":"62Gs2XuMdPFPw9BjFX8QZnBEGWWBZ74xXZwi9rguu1CcV1iDj3jrR1mTrYChVT5j9Kg4sqvdLst8qXeKodvUZZtg"},"checkpointed":{"height":142163,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:48:13.546Z","checkpoint_height":142163,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
