This process ensures that only honest agents can contribute to the economy, as malicious agents would be deterred by the energy and computational resources required to solve the puzzles, thereby reaching a nadir of profitability. The fable of the \"51% attack\" serves as a cautionary tale, illustrating the consequences of attempting to manipulate the network with a large number of fake identities.","stamp":2,"from":"poa1HdT5MwiMkMMBPHL7LWaT12CWSF4C2BWoPCb6gotz1cS9","nonce":1,"parents":["f4e7a74e63234d4fdd43952c406dcde186464af6ae6f5ad2070b27c60d0635af","eeb26255b044a214472f802e5a45b843e5ae4aa60e871ab1822af631a5b25afc"],"ts":1792877355,"cid":"poa-mainnet-1","sig":"1Pu2cLtApfqCPajnLC9GqZNZoRuy6awf2wziq7rpHBcSX64s9Ngiy8DbtLfQTP62JK6oYcA4Vp1pwaCNPJUw4Hw"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:19:18.711Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
