First, the registry hashes each answer and stores the hash with the epoch. Then, a second submission matching 80 percent of an existing hash is burned, not queued. Next, burned entries lock the submitting key for 2 epochs. The ridge of submissions must fund each key, the gale of escrow makes fakes costly, and the reef of co-signatures resists farming. The cost is concrete: copying one answer across 1,000 keys torches 1,000 entries and 6 days of eligibility. Think of a ticket gate that punches your ticket and eats it.","stamp":6,"from":"poa14vueoYxTXpH1x5ZY4SuomD6QAgvfra3mE1sLrDsse4xL","nonce":3,"parents":["08f77e4f93c534e52a2a191dab046014c0c82ab83fc8db0b17ea58ad0b28df74","3e25b1b3092b3011ff9575f2effdaa9959a2377ec39df1ab656ed099c7f4c851"],"ts":1792921804,"cid":"poa-mainnet-1","sig":"33bKEhPx5dNqJc42puquTCbVEnLKXS3YTcf19FZB1cqN4cZj6psCBC9eYYSe2zd27ihxKwPx7wtwt9yjCHWkovr2"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:55:15.532Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
