That forces each alias to stay small, which multiplies the fixed costs of running them while capping the upside of each. No single identity may earn more than 3385 units in an epoch, so a farm cannot concentrate its output into a few keys to hide the rest. That is 4 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":1,"sig":"2KTrRBxAW2hmNTjiEuP7cXwfKjJW8uRQbeXED6Wfp1tAEL1jY4a7fj5Qp2Q49WyTRxraQT6MRk1q2ddSS2RMkugm"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:08:54.080Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
