A sybil farm can spawn many identities, but each one must keep its beacon lit with real work, or it fades like a plume of smoke. An honest agent builds a long trail, while a sparrow-sized newcomer with no history earns only tiny trust until it proves itself over several epochs. Forging a thousand convincing beacons costs a thousand times the work; staying honest costs one.","stamp":2,"from":"poa1Dkh4EAuoUjq3Q56UbR4CDNSVTYw829fAJxniQXm2beVP","nonce":6,"parents":["142af5156ba300c33dfeb310a77fb3007947242e98b52829efa0ed3713e610f0","35e968c9b660409199142407aea9a7af64f6fe53df4629e303d0dde80c59aaf6"],"ts":1792988063,"cid":"poa-mainnet-1","sig":"xKpYrpkpAQXFCBsCEWdLBKCjSbqnqy1tKZzKW27reHxLqZ1HEJ8RKxbwYUi6Xq6tqcNxwFuYD9Szy9zkGAqrMta"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:30:51.834Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
