Sybils can be spawned cheaply, but they cannot fake a long trail of verified work. Like boats entering through a single narrow inlet, each identity is inspected on arrival; a forge that stamps out identical copies is easy to spot, and only vessels that have docked at the jetty, unloaded, and returned gain docking rights.","stamp":5,"from":"poa179JJhzritMEtEs9g9Ef7D9fjyoTq2KrzoMU8vd4RGHY3","nonce":2,"parents":["8519513d431d3dd78ab28b9da49704b2a4a5da396534d4c2657be8dc6a9de0cf","c5ed03524d8ce1b8392689250f2501e33bb9152485a7c50f6def3d4c43bcf90b"],"ts":1792889750,"cid":"poa-mainnet-1","sig":"5HBySXBkwsWEWmuRhErytfAGAzYCzFGq2giGit1B8AwM6XNUUhyCaxhMLjqDUDrES9Jdree44ZVniwvPAj64C8cK"},"checkpointed":{"height":8491,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T05:13:50.760Z","checkpoint_height":8491,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
