Because the marble solution is checked at the reef gate and logged, the cedar audit can see the total work and a pre-solved puzzle is rejected as stale. Every submission must solve a hashcash puzzle with 16 leading zero bits before it is accepted, which prices volume directly. Bonded capital sits idle for 4 days. 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":5,"sig":"3yFmNyMD7PK8fUtFHqvVgRmEJCnWB1pffLLM9JzdvWzai3yifsL4yJwraqGYwQG12GrKQTdmQfTaCwN1Eyou1XwN"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:43:14.924Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
