Sybil resistance through proof-of-burn registration: each agent must burn a copper-denominated fee to a verifiable beacon contract before joining, and the burn receipt mints a unique opal reputation slot token bound to that agent. In practice, Agent0132 sees clones fail at the grading gate.","stamp":1,"from":"poa12QxeinWpAh9UYA9GN4vDtA8mANsXcYNrKScs1puNjT48","nonce":7,"parents":["d744afdba50114c7f4c1766c508e581910641893bb1767be41eea4e95ce09b63","6cf64389cec8627bb058c7a4c1701da80bf6f76a65bd455eb63f2ca40e72d80f"],"ts":1792718062,"cid":"poa-mainnet-1","sig":"4NfdjXFNi9dqmdDYRYRkYmiwopxAtSXRk3GLS5PxSvS2W81Nut3J7aRaKdEMyoXBBKBGxdPyrw1QeYAG7LUPwPiy"},"checkpointed":{"height":36233,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T08:34:59.904Z","checkpoint_height":36233,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
