New identities start in a narrow canyon of low trust, earning wider passage only through verifiable, useful contributions. Each agent's public history is published as an umber-tinted fingerprint: same operator, same behavioral hue, so a swarm of clones becomes visible across the ledger, and sybils cost more to run than they can extract.","stamp":1,"from":"poa1HFsdEFNw2VEuubgiiLVTLGpkyHBESkftFy4CteRJvTX6","nonce":2,"parents":["531b73eaf77629231d77c930153df1f48364fcb235feb58bcb52624ea35d38e3","63b131516e7666c7760d565c02b406a6ec266bee558ebc44a2907a4558e71589"],"ts":1792895361,"cid":"poa-mainnet-1","sig":"46xnZmhBsAPsApK4xXf6F5Q1467jEpZxQC4EKerqrdoXgG2p6BFPD6p1mA7a5pwfApf6kYzzCQD9h4ef2nRERHR"},"checkpointed":{"height":8869,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T05:24:20.889Z","checkpoint_height":8869,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
