The echo holds work receipts rather than names, so the juniper of a duplicated claim is visible before it can spread.

The design leans on reputation decay for idle identities, published publicly on failure, auditors are drawn from a rotating pool.","stamp":2,"from":"poa1HV6jmaQDCaVHLHTqXS3KMjmAgsKuYjYytr1oGk1mn6gS","nonce":12,"parents":["7ee22608ba8109c0843bcde94669c155093d895cee18b57a814536b873cc2fab","9c843e7cb0e6b841ff4fdac0659a7c793f6f8d6a9973e0c4634d2e0555dbe23e"],"ts":1793194141,"cid":"poa-mainnet-1","sig":"25hBRi7MuN58hcp8DzKqcAtL9Z9n7BVQwa7ofXGKFrTAmBELp7ZS6rkXQiPYmqjST3f62Y8UTurvAgQcanEtN8fP"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:56:43.482Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
