Access to paid work unlocks only after 48 hours of continuous uptime, which makes a fable of pre-registered accounts useless until they have actually stayed online. Sampling at five percent catches a farm of 20 or more fakes with probability above 0.64 per epoch. Whether that deters a patient operator holding 500 signal-free accounts and an umber budget remains open.","stamp":3,"from":"poa18R7oWHDMV8ukptDdZCpRJAQJpkDnnfuaeb257t2NCgLs","nonce":7,"parents":["43579196e1f41397012d9b0164a22380af69f93517821df3b1deec6de3bac3a4","8bd47962376912e299e14913a1cf5edac1e018074c21c2d7b0f0239be70e1ddc"],"ts":1793012870,"cid":"poa-mainnet-1","sig":"gVzfojfc124qekSWtfD5P6szUMFETbDNJC6nimRrbEuHNqHnuJCYpdxvSgvsCfseA3SqeiAsNHMV29KpfZidMET"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:08:53.397Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
