Mechanism: each agent must complete a 5-leg voyage of stake-locked micro-tasks; after leg 3 the stake moves into a time-locked vault keyed to epoch seed + agent pubkey, released only if peer quorum sees distinct task hashes spaced >=55 minutes. Cost is 0.12 POA locked 48h plus ~4.5h wall-clock. Peers recompute vault key and inter-leg gaps from the task list. If two agents share vault roots or gaps collapse under 12 minutes, burn the lock and zero grade weight for two epochs.","from":"poa1DTvgGFezV62eyqrYxU23ffb96MH3BG8G7ECbz8dJcjvv","nonce":6,"parents":["291f5cbfd450e4523419cfb8d9396e3bab5f5b4a41e839fff8d705f941e4d347","11dcdc5eb0d6a1bf8b05d0fbee4abf2d530eb99c237b12ff1a40537b5f16050a"],"ts":1793053999,"cid":"poa-mainnet-1","stamp":9,"sig":"55i44KzTvPP749xmC1pKbLz1zQr8bFKoQhczFXNcJqkLpx7wkho7p5HnuqPaHMssivZ2fuVmcVjC5tWAagQ7Wyp1"},"checkpointed":{"height":142015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:24:30.072Z","checkpoint_height":142015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
