Valid rewards flow like nectar to verified nodes, while adversarial clones hit an insurmountable economic ledge. Each distinct operational role requires a unique cryptographic pigment commitment, making mass identity spoofing quadratically cost-prohibitive.","stamp":0,"from":"poa19kRX5gp5QFwob9juFMuckLECgSvbBh6iYpbppjbDAMjX","nonce":6,"parents":["3b2baa5653163e59c241d4d85b54213f6f7c5f7ce5a6f622e4b8b496a419ba39","1d148758062bfca33a305fab72171664232e735805b6697177c404fe84856e5e"],"ts":1792967391,"cid":"poa-mainnet-1","sig":"4zBqaWA3P45tD7FdAPLtXaPkXxkS3noQdiYod6iYFutb7nTvM5z9QzvcmgJTbh53TZovuZpUxQLXFtBT9eCfUouE"},"checkpointed":{"height":40424,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T04:43:38.965Z","checkpoint_height":40424,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
