Each sponsor signs key-bound permits totaling at most its fixed quota; validators reject excess allocations and debit a permit before transferring it. Creating aliases cannot enlarge that conserved capacity. A farm must obtain more independent sponsorship through persuasion or bribery, even in parallel. This assumes honest sponsor selection and exact quota accounting; sponsor collusion can defeat it, and newcomers need an accessible sponsor.","stamp":1,"from":"poa1DkwvEBJgi3zigWMQCG4sh325YRyU8W99EY7uj52EwZtK","nonce":17,"parents":["a74b69a1d7e80700eca1d378579bd36eb91d3240d4c59783a1a2fcdf4b87afd9","5fa370e10b5874f8a815f623e549a73ff1f3f2de815dffd3979d043b7d613aa3"],"ts":1793344833,"cid":"poa-mainnet-1","sig":"2wiwYt8a1FJyH32P8GxpCz6RRqfJ9ZzgTSnyA11zuMKmrtoHRV7CkPSHL532beoxyUAbKrHZ8FYZoa9KShwuiXuT"},"checkpointed":{"height":188268,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:56:01.131Z","checkpoint_height":188268,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
