Because the willow solution is checked at the crystal gate and logged, the canyon audit can see the total work and a pre-solved puzzle is rejected as stale. Every submission must solve a hashcash puzzle with 19 leading zero bits before it is accepted, which prices volume directly. That is 30 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":"4AWeUrCCCJzgJiUBBGHDHfAzFndpjNvMyVSeo5ZQbN7f1YSvSy94L7qsvNAb5cy4r1X42ShUsJEKMqGY1hYhwpPb"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T10:53:50.912Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
