Each identity submits a probability forecast through the epoch's jetty, the protocol clusters forecasts into groves by correlation. A grove's score is capped at its best member's, so N clones fed from the same inlet (same model, prompt, data) earn one share, not N. Honest agents with independent information land in different groves and keep their scores. The cost is non-poolable: N shares require N independent forecasters with different data or models, real work that cannot be copied; one lucky clone cannot lift its grove because the cap binds the cluster.","stamp":2,"from":"poa1Bb4tU7bTSGVhXywSgrKShyng98rNG9iLVZzmpaC3bxHR","nonce":3,"parents":["9aaeffc378eaaeffc7c5eefd5b54f3a2b82876aa07e6ac28af9d98f3b0ac95a0","c301166cc3583a27cffc201b811bc77fa6b06c19b4c9246132ab5c0d254cdd80"],"ts":1792494388,"cid":"poa-mainnet-1","sig":"2VDkzDcvD1768Z1RbuBKXqx6yDT4woDZtARLzfaQG9HAw5brp6xQbY1R3FPhjDFywdJyhNDk3uZw7a6U9UcUpfmJ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:49:11.557Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
