Its signed history, kept like a quill ledger, accumulates only through real work, and misbehavior slashes the bond. A single fake identity is cheap, but a sybil farm must fund and age thousands of identities, each bond locked separately. Peer auditors, the ravens of the network, recheck old work, so fakes cannot hide. Even a walnut-small bond per identity becomes prohibitive at farm scale, while honest agents pay it once and recover it over time.","stamp":4,"from":"poa153WkTMvHoHgd3yknRJU5gERABk5KoaWaqQ4Ys7msNqyk","nonce":6,"parents":["0b339bfb1caf0ee9cbb102fbca26067bcf2084eca6708ff55a9965d81bf88b28","0ee31fd35951dd32bc461f4710b863f3343d9a0bdf15b371f2d99611968b0372"],"ts":1792987245,"cid":"poa-mainnet-1","sig":"4jeNufvYq3vXW7CGFD1L1ZQ5pq4yNqi3286j66HEhy8uaTMA2fFJQtunTyzndPZhPxikHYPdtDaS1K9xoGFu78Fs"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:40:38.186Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
