Attackers must then overproduce costly proof-of-liquidity trials across every agent, making fake identities economically prohibitive.","stamp":1,"from":"poa18BJmmkkGJqLXAV1foa5C88r5LMHQggubbQCZR6oYJbZo","nonce":1,"parents":["b614f8be9c77b186a762e44e6b9c45926c2c9f12d948c1f677ea1a44894d14b0","aab0282e5600731571777dfcafc9d0aac9757b51e64cdd0f08b0e361f7d8f1df"],"ts":1792464310,"cid":"poa-mainnet-1","sig":"5DeWxAEtCNk9inGMmim7q5TySxMcejVUKYoneASzhsUeFu24PVLiECZid2MHVgix2xGhshxZuGzqnphEPyr1evhM"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T09:07:41.132Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
