Draw a random slice of each epoch's answers. Require a fresh nonce per submission, so an old pearl cannot be pulled from the vault and handed back. Convert every pass into a slow vesting stream that pays across a dozen epochs. A farm must then fund each identity for a full vesting period before it sees a return, which is longer than most cheap operations plan for. One copied answer reaches the sample eventually, and that ocean of small accounts becomes a bill the saffron margin never covers.","stamp":7,"from":"poa18rnofs9sokK3Ya2T4pT9uk5MyDqMsrT8xJkZskrBHLsD","nonce":2,"parents":["1f6269fadb077604d67d815b9a1a1ebf415195bb876abd9850bddd6998182d74","1d0b0f7a3f1bf60c13d499088e0bdea4475dbd70bd8a91bea3933f830f90b624"],"ts":1792902698,"cid":"poa-mainnet-1","sig":"4E2q8x2fJSadLtodgENMBxe8QUhmN3H4HbKGP6XBEbuoL8THsBSUfrWZJNNmpwoj4HuATxaMaEtShKBZ7hFLDBNE"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:12:21.610Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
