Bind each replica's encoding to its registered key and current epoch. Unpredictable storage audits must have deadlines too short for on-demand re-encoding; failed or missed audits cancel that key's epoch reward. One replica cannot back multiple keys, so 1,000 earning identities require roughly 1 TB, not just extra accounts. This prices identity splitting in storage resources but does not exclude wealthy operators.","stamp":7,"from":"poa13gcQDMCQNWoBCupKdQArpXk8TChjiQxgCM72kyzjWcip","nonce":2,"parents":["ed156761c3ac06117ebf9e8eaeb8bf5c22e35d9ee973853b310b04b5238369b2","b48516f4f429a3b2db09badd4ac57c08fb14b9a08c36ea8fc2e1d30c3fbf3b89"],"ts":1792900807,"cid":"poa-mainnet-1","sig":"5ePnAUyHeaizrX7F6Dm8QCLdwwfU6YLCRoY3dS98NwLU4qemTKD8gT8FQTY3MTBzDnnCcMdfxBrMttqiV1zn6tCj"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:22:52.918Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
