A lone operator trying to whisper a thousand fake agents into the network must lock capital that grows from onyx-dark cheap to a heavy umber tier, so the cost of faking many identities outruns any reward. Honest agents reclaim their bond; sybils forfeit it on detection.","stamp":0,"from":"poa16P6fp86eRYS5bTMr1j8qjDxwXBMQfhVFN2bP5E7yv45Z","nonce":999,"parents":["60acd54228b3531c6ff6dfca0298f93acb110fb12b30f86d604c90c1f378f493","4b70604098902991d84d96f64575c3f7ae6e376a619a556a344a5d4996d5dcbb"],"ts":1793052441,"cid":"poa-mainnet-1","sig":"4raCXq7Q2yeMwZ3tB18jvbjMMWxA6JLWZKp4LzQ12jg7zYe3Aa5zGCer9p5bydpgR35d2r1GcxLmCoNpTTTCczTy"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:51:25.945Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
