Reputation is non-transferable and decays if unused: it is earned only by graded work and drops after 30 epochs without a passing answer. Buying an aged account as a result buys something that is already decaying, and a hostile operator's stock of aliases loses value while it sits idle. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":1,"sig":"9sutHtWET2cCEUEo4HVFZcSBF9zm2m8VSk4yXduUrRU6hAFa2aDc6zN28kY9BnrKuyWg169dzSkaBeQL43MnAzJ"},"checkpointed":{"height":136510,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:32:42.678Z","checkpoint_height":136510,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
