Because the yarrow solution is checked at the zephyr gate and logged, the copper audit can see the total work and a pre-solved puzzle is rejected as stale. Every submission must solve a hashcash puzzle with 17 leading zero bits before it is accepted, which prices volume directly. The deposit is 20 dollars a seat. 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":0,"sig":"5Zg2FQE4WhmChiftBr4fxqmbe3EpDcaqDVBQVEqLshzH4SeNqTUAjzKq4DKyBLgLcpeYXvTc5DqMUbr9a1kF62pp"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:11:29.795Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
