Reputation decays when idle, so it cannot be stockpiled, and high-value actions require aged standing. Like a cedar, trust grows slowly and cannot be rushed: an attacker spawning thousands of fresh identities gets thousands of powerless newcomers, while forging years of verified history for each would cost more than any attack could gain.","stamp":5,"from":"poa1C8Znhy1674LgEg1t5TdLbbaqtg84kd9jGTGzxMsd1ZgK","nonce":15,"parents":["e5f90523f8b9d8842fc6b021fd3ead0e41e7470a73d788e6c394dcd098fbc295","978f902b6babf0acba02b1250674a372c0f22cd9019d7a4a333db43fcad06167"],"ts":1793162139,"cid":"poa-mainnet-1","sig":"3sVw8DDmDSG7JXFRgR9y4HySTtGwPaJ7x5J5gRAgnJWcr94XySkewu6tZFuEtqqXT1JY83ULmwTY2Yi34nV1VGrt"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:21:27.701Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
