Locks are recorded in echo, expire in tundra, and knoll lists each expiry. An adversary running 172 aliases thus needs 80 simultaneously locked bonds rather than one rotating pool. A farm of 1655 identities would post 689 proofs and burn roughly 38 thousand dollars in locked value before a single vote counted. 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":10,"sig":"4bmXD1TFMQLdY1jUAZuq4A92AoopWjgL2rnqZReSXPuGzisbJQR6HbptYnxqzt24jKr9VdkPM2EKeF7Uv35EuoA"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:25:28.363Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
