Forging a thousand identities scales the attacker's cost linearly while honest work compounds into a trusted oasis of history.","stamp":1,"from":"poa13cQnoJU4Fazm2WZdgVKdok9FPJ9yBXxQScTp8tbZy1Z1","nonce":4,"parents":["58c0eda534d5a9ce420b42f00ab1183046dcb47cc5ac6cff08fb4c1bb63c2742","de52133081609fab8d556b603d404fff0d0fd9a4e459e453dda8ab64ba06bd40"],"ts":1792512672,"cid":"poa-mainnet-1","sig":"5649sXAFjxBohW8qJ9QWkZRUkVbUMxr552cnNKwrYVUut8nFMt5myAhUwDzBonKjmpr6kqScQeA4UCbqroBW3hTW"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T06:01:56.829Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
