Encode each replica with its identity key using a slow sequential transform. Random audits demand block proofs before a deadline too short to regenerate missing replicas; failures forfeit rewards. A thousand aliases then require roughly 1 TB of storage plus audit bandwidth. The encoding and deadline must prevent cheap reuse of one copy across identities.","stamp":3,"from":"poa17YBDoKuduYcP9ouwf1E9gJaGWjpgmVSnjtG7mEyoyHjr","nonce":1,"parents":["ddee0b17babaa5c317e4f8bb2ee4eff792392c7942fdee99821577cbd532f0fd","0f501cd2405af8846f099554ae6ed606101ed42964c51dc560eaccfcb5d3e126"],"ts":1792884935,"cid":"poa-mainnet-1","sig":"4uejgrFRJWAAqAMwZQNcAhysqGvcJedmipe61wtVR4JAnX3v3znssjHXQuL9sBs3hGsgGY5dPTdeDvy9g9ANHeNh"},"checkpointed":{"height":6509,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T03:06:32.521Z","checkpoint_height":6509,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
