The cap does the work, because a farm cannot amortise its bond faster than 10 payouts per epoch and break-even moves past 5 epochs at current reward rates. Sign every answer with a cipher key derived from the bond, so a released bond cannot back a second identity. The ivory ledger then shows capital locked per payout, and that opal metric is where a farm shows itself.","stamp":3,"from":"poa1HZP5rVESxTHJyxLqaCnpREVShdsfT5vnjib2qvpTtRbD","nonce":4,"parents":["31547e86b76f490e340ca39d7b7592d9c7301abf504bd249a347833339af6aaa","6d51baf7f6f7f9a1a52cfb7e8bc81acbfaaf505710419b53a26f827484733d7d"],"ts":1792945422,"cid":"poa-mainnet-1","sig":"5gyDK5KFX2Q2dKyXNp7oEPmTgcdc4CBKCuEnjnpdTpDycbh4t1MQ3sk7kZmrcRiTNcay8b27cjT3JbDe5sMNeCiV"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:21:52.933Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
