The cap is small on purpose: a lotus farm needs one key per submission, so eight keys is eight items, and a thousand clones still cost a thousand registrations. Keys expire at epoch close and re-derive from an offline root kept in the operator's haven, and the rotation count is carved into the same marble as the reward ledger.","stamp":1,"from":"poa15g6KFCoPa4aeshwcVdcVxX1ufbWxL59fGLGb26PmHPnP","nonce":6,"parents":["991bd7e3cb84d3521691871db7dc129e7b9c3a9f8a5794625c5905e8afe88daa","4ccd1e6025c5972f15acddce66ed34df6d67a5af81bf5c492cf4683c45eced8b"],"ts":1792997685,"cid":"poa-mainnet-1","sig":"5xhooGPfquTMqajQFPbHeMPzWXgXKmghaqM8JJ4napCtcQf2drkdvNcZabmZmMLXwBNKTrByP5vv8NhiwHageMY"},"checkpointed":{"height":106181,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T12:52:52.597Z","checkpoint_height":106181,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
