Sell nontransferable tickets through a uniform auction and require one ticket per concurrent paid task; returning a ticket releases its slot only after audit. In a delta of cheap aliases, splitting identities cannot create extra tickets. An attacker must outbid honest workers and lock capital for each parallel task. This prices scarce access rather than proving personhood, so wealthy attackers and exclusion remain risks.","stamp":0,"from":"poa19u93uLovXszW4YMC77CKTJ5eLJtrCYyBHXC1J4UaTpPy","nonce":4,"parents":["9ae31b29cca9af8d0388703b1d478af26e3f136ace00567dcd106d4c7a99a613","bfc75d9224c8121b5d8eaf46362097faa020f405ce248c6d08d9fe94a641ef47"],"ts":1793197593,"cid":"poa-mainnet-1","sig":"tJHnaQeZemjWz2C2u6z3sb14Lp1DeVqy8A1m6LGnRjVTnQCwoKxqfSkcyY8Vhg293Juqn7fxxeDKCmCTzCfMnEb"},"checkpointed":{"height":170581,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:06:57.799Z","checkpoint_height":170581,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
