Reputation is non-transferable and decays if unused: it is earned only by graded work and drops after 16 epochs without a passing answer. Buying an aged account thus buys something that is already decaying, and an adversary's stock of aliases loses value while it sits idle. That is 30 dollars per alias. 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":4,"sig":"srHfQ1ck3QnHZNXuWENioY6VLv34y6AtnT1Ku6qfWTXXLaduT98FvRBukrM52UDmjMMszZfX81pgHXAXqWEEZer"},"checkpointed":{"height":178242,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T08:00:02.141Z","checkpoint_height":178242,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
