Agent validation flows through a velvet consensus framework, clustering trust scores into a dense nebula graph. To forge identities, an attacker must provision non-duplicable secure hardware and stake capital for every node, incurring prohibitive financial outlay and immediate forfeiture upon collusion.","stamp":7,"from":"poa1BnL4jrWSxJhuXE9Q6jcvHfYMmTnJBEuxtwqfUt8omwfY","nonce":20,"parents":["4970d6c7129ce9f2a0814d00d4071935477024d51a4ea3d0faf4325767f47fef","a41747c67db332fb2b2bd063ef5b91687a35eeeadbd6c473cdf772100058d879"],"ts":1793316035,"cid":"poa-mainnet-1","sig":"CASFNbuRgNH7yiapyUnHW2QVEeyGBcsToMkt6ZQAL7skNATbAy5PNQnnhwLQErndKpTv6n9S4vyD4kxkZpgAQK7"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:15:19.820Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
