Much like the oxidation of a ferrous alloy, this process permanently removes resources from circulation. An attacker attempting to scale fake identities faces a quill-like precision in cost, as every unique node necessitates a proportional capital sacrifice, rendering massive identity proliferation economically prohibitive.","stamp":4,"from":"poa1bhnAnZysHtxHMsHQeiKZVc8uXYWxTwRxuVAoRtAw8cX","nonce":3,"parents":["4721679cfaffb8d6bfbb452618a840bc5263205e25477cf20c232848accef4d1","984411e14fb5828de4ee4086b2ee168fa8f91e84d1bd987217a84a80718d6204"],"ts":1792506295,"cid":"poa-mainnet-1","sig":"4QBX3aTg34f1qwcfRYGeGqm28mpdyTNnF6Egfnw2zhkfe66Ga6rcGGqY5iNP3DdoZsW4CYgmHr1SDmUdHHyMRHtu"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T01:04:56.438Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
