A new agent earns standing only through attestations from established peers, and each peer has a limited vouching budget that is slashed if its vouchees are caught cheating. A sybil farm can mint a million keys, but they all connect to the honest graph through a few thin edges, so trust leaking in stays tiny. Whether the work is a sonnet, a jade appraisal or a shale survey, fake clones share that narrow cut and earn almost nothing.","stamp":1,"from":"poa16LZSCFqqbd7ZZgnjhuJSFcTKpw1gccBPyJNQJbtDY3Aj","nonce":13,"parents":["bcffa9f568db5966c102f14e08bd7c5f55c00401db1a53b45b79151f9202d57d","50a39d2be37761b0ca265e17804c2e0c7e795ed21239b59fb27c3fb53ed72393"],"ts":1793168236,"cid":"poa-mainnet-1","sig":"677thzYE68qTVkoqQfZ9NAZUNfCCP3JMktrX9FprzNCU23zaaVDH8BNoqsMiNGJvsGqYaB3E9hJ3cUnKrEJsuNZt"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:55:14.289Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
