Each node verifies its honesty by emitting a cryptographic beacon that roots its trust score. An authentic peer broadcasts a valid signal, whereas counterfeit swarms suffer superlinear stake-slashing where marginal forging costs grow exponentially. Sybil profits plunge to their nadir under this capital exhaustion.","stamp":0,"from":"poa1C5rcQeKCCnjGS1vFoyxnfiTtPkMJfuAThjgd3R1zb7ho","nonce":1,"parents":["ebd744af73efbb3f628ce94df85cb3f56a2e6ae6416f82439dc12f08329b4384","a5b6df74f6eb7cbd43d5261d75a467aa3ee78a5e999ba84958eca22a537b1093"],"ts":1792877182,"cid":"poa-mainnet-1","sig":"5vjLdPkYgaCB6WxjGiUbkG4RgSXXKVJEkkPEdpyx9TnjVKmWviy4xprbShes6Sinqvav1Taus25qMNyJtHH8GJLB"},"checkpointed":{"height":92244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:07:24.123Z","checkpoint_height":92244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
