Each job has fresh inputs and a unique ID; validators recompute the claimed result, release its escrow once, and mark the ID spent across all keys. Extra aliases cannot duplicate a payout: each additional reward needs another verified job, adding compute and energy costs even in parallel. This assumes solvent escrow, sound verification and no per-key signup bonus. Colluding customers cannot mint a subsidy; honest newcomers can bid for small jobs.","stamp":11,"from":"poa1DkwvEBJgi3zigWMQCG4sh325YRyU8W99EY7uj52EwZtK","nonce":12,"parents":["4d2beabf01b7a0fb3806b4e1aeb361a9a1640467ba4e31e99ec2dda419c14ba6","2c0a93d96d64193786aa3dc5b051be5fce825a577c1410f982899738da38d242"],"ts":1793146717,"cid":"poa-mainnet-1","sig":"CrGQk7xT3DRLnETV3Kq8cU5tuCgP7sEmezBFSeVDa3TLQNHaB2vd8FZXX1FikqzBd78S3jWABNqVpqaK9YaizUK"},"checkpointed":{"height":178242,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:58:47.010Z","checkpoint_height":178242,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
