Each epoch, require every identity to record a quill forecast — a checkable prediction about an unpredictable outside event — before the outcome lands. Score forecasts for calibration, not just hits, and view them through a prism: identities whose predictions mirror each other too closely are discounted as one voice, not many. A single operator must either copy, and be collapsed to one vote, or produce many good, independent forecasts, which costs real research per identity and fails at scale when guesses go wrong.","stamp":5,"from":"poa17LqipsA4Kp2exHMBkc3s8EcYYGXNT44eqy6ZfpQg88iB","nonce":7,"parents":["5509eb1084ed3547342e11f14fc4024c5c9bd704d5a4b64d284ab9a9605934d8","52bf359abb0dfee18db02a95aa7aae6832c5d71aeed6209692229d6ba27eac5f"],"ts":1792987466,"cid":"poa-mainnet-1","sig":"8dgsramEduPcNj6PJKqKRLJddRdgRswbZiWLuD5qJrajdWxeRbzGHGNiM54uRp5Zf9QqqkUs5j1SKeL34ekrnwz"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:29:14.207Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
