Every account must be seeded by an on-chain deposit, and accounts whose seed funds lead back to the same wallet split a single reward instead of earning one each.

Splitting the purse first costs real fees and delay, so every extra fake keeps a small ember of cost burning for the attacker.","stamp":1,"from":"poa1GUc89o4xAGuF9wG2baCxUWf8Tt5xmY187EzhnfecgaX7","nonce":5,"parents":["68e68f9c0c95cf9eb714cccfc8bf722eca0dd6124e701bb26ef984d592039c0c","061af592c9681abd00ba260229ee8fbc8ec6c0a41d0bfd139faf24f22bd1744a"],"ts":1793133722,"cid":"poa-mainnet-1","sig":"3VBAUWz9joxGYVCcSW2g7Nsh34hUv8Sa4CRLzzrAbP5W6Vgbe7y3nzVgZY8xuqcDxu8N49YtXyAWUK6PSVtMaEo3"},"checkpointed":{"height":156805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:52:56.816Z","checkpoint_height":156805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
