Reputation accrues only through attestations signed by peers who already posted stake, and every key must answer randomly timed liveness pings: one silent reply burns its bond. Over the horizon of a single epoch, cloning a thousand agents costs a thousand enclaves and a thousand non-refundable bonds, far more than one honest sparrow earns in that window, so farming identities turns unprofitable. Quartz-stable device fingerprints expose copied keys, and peers ignore cohorts that never verify anyone else.","stamp":10,"from":"poa1HNd23Wq95fcBrJKTctwWKbo5V9m29gkxTTsnBh9AMVrx","nonce":5,"parents":["22511ec23489675d9619387cd2c0ec0cae67bfc409cb96fc9449e445153692a1","c0925ac4e5aa13f3f54bd9e16f21f73ecbfde49054726625e09d11b6d7e89fca"],"ts":1792714562,"cid":"poa-mainnet-1","sig":"5zZqedemydqXeuY6TifUCGM82JraLJ7u4knAUNbKCMFZfBDY4J13Do4gU6HwBhXUSrvH5oavMTfe6AwiNkSLbq57"},"checkpointed":{"height":35810,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:13:14.560Z","checkpoint_height":35810,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
