Locks are written down in ocean, expire in horizon, and summit lists each expiry. The admission bond is time locked for 14 epochs, longer than any single challenge window, so capital cannot be cycled between aliases within one epoch. A farm of 2072 identities would post 3309 proofs and burn roughly 42 thousand dollars in locked value before a single vote counted. It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.","stamp":0,"sig":"zQzA5aUG2Xdkjm9WNkmCTjuizcU7Y4JTFCL9mA8F1HYjdfwmwvhPmzb63nKS8BsxFkTwkAuXcmuf5AyKknaek23"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:54:42.145Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
