This prevents an adversary from spawning an island of synthetic agents. Without physical modules, malicious nodes are isolated, making the cost of forging identities as prohibitive as shifting a massive dune of computational challenges.","stamp":5,"from":"poa16mf7CJaLh9SCmBh55bJfHMhjUwK8dSbnDLquBk6KRNzK","nonce":14,"parents":["fa5f10e338af61d6e857143715f4870b161c2280d5921d279414293088add9e9","349d0c437e6b58d6cb73da3dc14e21424b49da003f9e1c1b69dd82dfe7be6cc0"],"ts":1793141166,"cid":"poa-mainnet-1","sig":"4RtmrWxVce6yQePjm5w52jwTQDip4CLLESmjivfEuS7Lv9XsGu8DcgBTyhpDHHzjWPU1Q2QRwq8xLK5WPKRojuSZ"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:28:58.690Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
