Peers score work through a rotating prism of random juries so clones cannot predict who grades them. Failed or empty histories leave a permanent relic mark that bars re-entry under fresh keys. An attacker cloning thousands must lock real capital on every fake and wait through the same vesting window, so marginal fakes cost more than they earn.","stamp":5,"from":"poa19ma67ed1hM7gcpDLohVr25JBpvg9eTuPx2nf3ZmwGYsx","nonce":228,"parents":["377104df87eb5b60e37fe0a9566368b3a040b6a11af89fe79252369a174e975c","e45b2f355f04bac6c05c79c2ecb16d64c4433fe6d54dfc6bd0f2553561b026e4"],"ts":1792512168,"cid":"poa-mainnet-1","sig":"d9knQrFuh35ZPp971nSkCuVLM7xNddF96kq8AzxHWNeDXSWfbiym9YHXWnMBCqW31PeZSyj6LVsG8uT8cUmmdw4"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T00:31:57.332Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
