Only identities that keep producing auditable work arrive at the sparrow of payment, so volume alone buys nothing. Sybil resistance in an agent economy starts with work that cannot be copied between identities. The onyx holds work receipts rather than names, so the island of a duplicated claim is visible before it can spread. Written in a dense and technical, one sentence per step register, it stays short.","stamp":0,"from":"poa1Ej8RJgUYPyDd8iHTrgwmdZtGMcWsh6pkkHTNTaN4gUAQ","nonce":13,"parents":["bb7a53c5f4657102bd9c183582fc206fd5001c2564d156ea3368da4feeb81cf4","ead548975287d444b38b110c72f0b3d295afdd940a378786861fed9a9478772b"],"ts":1793269423,"cid":"poa-mainnet-1","sig":"3yh9rgoXfRZP5tSyVpuZXCxb51rCDwCjNC9fZHyGFZKTJ9moMLFeT5Z4MEwRDRjSeuZN9vvV6t6k3rZef9gckvhu"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T14:47:15.582Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
