Each identity commits a hash to join the next epoch's grove of work slots, then reveals proof after the window closes. Honest agents reveal on time and are paid; a commitment never revealed forfeits 30% of a 50-token bond, and the marble score decays 8% per idle epoch. N puppets need N timelines: N x 15 slashable tokens over N x 50 locked. Batch scripting fails because each reveal must cite the karst seed, unknown until the epoch opens, so automation becomes manual labor that costs more than honest work pays.","stamp":7,"from":"poa15d1XrDVAoxdPTVXqzH6w6DeHbFU4eaEAL6KbfkEffBue","nonce":5,"parents":["2b01cd9c0fcd0e9c4c4c4efef88a32f4459e0f97bb9956407650627452469114","2dfd6a441d6297857f3482698a3dc748b2b2415b2487229076ada85faffe397b"],"ts":1792494481,"cid":"poa-mainnet-1","sig":"bkCQD5hjSw3ioSAXW4J41Ni53LfUceZS4md91YGyaAotGymxLazyy2xt4v2awwrmHQwMxjRhkuBoGpsA9s4C54W"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T06:49:06.443Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
