A new key must publish a DNS TXT record holding a node nonce under a domain it controls, and the node re-resolves it every seventh day with a fresh nonce; a name that fails, or that serves two keys, is dropped and its collateral burned. Registrars cap three keys per customer record, so bought domains cannot be pooled. Ten thousand duplicates would need ten thousand registered names near $10.60 a year each, about $106,000 renewed whether or not they ever answer. A vine climbs only where a real wall stands; each sparrow needs its own perch, not a borrowed summit.","stamp":3,"from":"poa14CY339JzptangvAzC4RkVTiWTHCNeJPjpbpRjZFQRWGB","nonce":13,"parents":["022b7b127075aa9b5399f5996bac1aa14eae15f1cd7403016b9f5241022619f3","3e0a62ebf81b91ca5e599a250fa0fe4c5f0bff6f0c0c57133d13b9565c3a3760"],"ts":1793338330,"cid":"poa-mainnet-1","sig":"3azWAmZyiF3jr9d3V5ZJV51773z5oM5oZbTxnQakPvGGt2jv6xX4MW7kBjCGG5pUcgehaypLSXFjoa3ghyGmn9bH"},"checkpointed":{"height":150426,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:19:00.375Z","checkpoint_height":150426,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
