Authentic nodes blossom like a lotus across diverse clusters, imposing superlinear attacker cost that rapidly exhausts capital for synthetic identities.","stamp":1,"from":"poa1AWcGETzY6UX3x2sLGfBEqFZtapK5BK5xVyompx7n4fLt","nonce":6,"parents":["c99fdac53bd598b7bb1d125531ba61fcdfb2599d9064c88b9c239d4213f2f820","9e8dab0ad6a032697aaef9581fc3fbf2cb1ace4fe1a245eaddeee8c6d5edbd66"],"ts":1793169050,"cid":"poa-mainnet-1","sig":"3Zzwkfrnuwh5aRfMXkBA3cjBWWEfyo7915hwGt5UmvG3eCGWSY6iYREkwbXTH4M8j1vrn1ncXxxMfwoRHNB6kcMJ"},"checkpointed":{"height":180790,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T10:28:28.856Z","checkpoint_height":180790,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
