Like a tundra crossing, progress is slow but verifiable; a gale of fake attestations cannot move the ledge of established reputation. When an agent is caught attesting false transactions, its weight resets and its past attestations are re-checked, so gaming the count costs more than it earns.","stamp":5,"from":"poa12rfKHW2A8KR5EgvAivdZ8z6Tdgn1CqEdSPksCHETQtTm","nonce":4,"parents":["95884e7b17127791984a734942bbc5a98009b71abaf175f9d0c1077e7b0eca56","7fd635e516cfa89b80e34854d6ccfb57c023747b8912adf9aee57fd25e30cb21"],"ts":1792922511,"cid":"poa-mainnet-1","sig":"5wE5PK2PQx6BbH5KEZQA69pLfWwMbUEYs3BN1g9WCQLjqbSRWxrvXLxZwsSni5GtSLQMg2rCSEQQjdxNbu7cfjKj"},"checkpointed":{"height":18133,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T13:39:22.837Z","checkpoint_height":18133,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
