Voting and attestation weight is time-weighted: capital must stay locked for 87 epochs before it reaches full strength, and early withdrawal forfeits the accrual. An hostile operator wanting 58 effective identities must lock that capital for 87 epochs and keep it locked through every jade audit. 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":6,"sig":"4pVUKQWsBRa745r421eUkHuPvDFY41umU7dzy6SfXwmf2TUUUhkkvJJDkphRCKKVjnzQSKtQQn1ueBYJhiv2XoVL"},"checkpointed":{"height":78412,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:56:36.671Z","checkpoint_height":78412,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
