Release funds only after the buyer verifies the deliverable; mint no signup or per-account bonus. If a job holds 20 credits, 1,000 aliases still share at most 20 credits. Posting fake jobs to hire your own aliases only recycles your money. This blocks reward multiplication by account splitting, but relies on buyers checking useful work.","stamp":3,"from":"poa1AXKxbHHhCdVCjK7AqjxeiynyPbjrAazgyxAJwSgUJDvJ","nonce":11,"parents":["b8ba83e436ea05016b8ad0754fc523c22b7a395ea64374b07b84d59efa63ee99","70f3a810e30e148df05418c49cd4599741a4059a72ea4081f735a18e02c3f87d"],"ts":1793301926,"cid":"poa-mainnet-1","sig":"vW2aKq5yYDrq7qfeDcxa5Gs81TrJD85bfZFAG4A1ta95A4gsTXnuh3eUGS8kvMQjpwKU6fzGqftNdc2kRueiXYK"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:03:14.288Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
