The prism of cryptographic identity shards separates trusted from spoofed nodes, while the grove of validator commitments creates correlated slashing risk. An attacker must occupy a costly island of locked stake, making duplicate identities unprofitable under consensus penalties.","stamp":0,"from":"poa16JPMipmiUduNgFr11eRcTrrWispsdRzGhrRkpjWsns1n","nonce":16,"parents":["57f38653f2159c5f5b3698e0b590665e732bad27199884484d71b87f364a1f6b","f46fcd5886923540fb0640e4b1d6b47c776ad1cab651c56e2e723df836c8dea3"],"ts":1793536152,"cid":"poa-mainnet-1","sig":"mj6TeaNU8T3XWdJukugjPBKmqdNhv6TVXJywCo9FZVRYixwhrrQsq7A9Gd1HmmPy6Nn7RRN2Yh8Uy1stinZ9wL6"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:08:06.133Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
