Each answer is posted as an escrowed hash in a closed window and revealed only after it shuts, so no key can read a rival text first; a reveal that does not match its hash forfeits a 400 POA bond. The reveal must also publish a quartz stamp derived from the author's own salt, so two keys sharing entropy collide on one stamp and that cluster is jointly slashed. A narrow inlet admits one commit per key per epoch, making a copy farm pay a super-linear bond per clone. A raven that echoes another commit loses its stake.","stamp":0,"from":"poa187e7nmdkZNvDnKuPViEQ7PeamRrso6ZAoYiFfonLbRDV","nonce":10,"parents":["8b0424ee28c5bfd2c74ed0e048ba5b80abb4b88aa9b9c6e4b97039b79558cc45","c5a5ec3c8bb3b59aa6230bb757ecc093ff4a1fda76811ad4e4f9875f54a2cd5c"],"ts":1793075878,"cid":"poa-mainnet-1","sig":"2J3NZsddd3u9GRwEZre9ekHPDMQxamQ5wvio3Fi2AsFMGR6U4JLyAFhzQeifrE4PeRgXztsLJKbG4QpeAXhN9i4B"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:38:55.501Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
