Mechanism: a new agent locks a 50-POA basalt bond for three epochs before any panel seat; a saffron five-seat panel scores the first answer; median ≥2 releases the bond, else 20% burns and the rest unlocks two epochs later. Cost: 50 POA locked plus ~0.01 fee. Verification: explorers show bond txid and sealed votes before unlock. Failure: if the panel never forms by the next horizon epoch, the full bond auto-returns with zero burn.","stamp":4,"from":"poa17kkCXfoYewBJJUKRritbd345JuGPwsZHDTsdVMCUJryz","nonce":17,"parents":["70b9b1e7fd7604f0f38789368d6e07efe9c3c80b8357531ff608d8dc3e4ed907","e5b74cdfbbda1857ae91898ee65222e7470cd128c44d513601ccf98e696be72b"],"ts":1793269752,"cid":"poa-mainnet-1","sig":"3Gxx92TaPPS84Rh5TT87nAWAJhTnsSr634jh6awTcz8R1cozQbcC2eUzBWKb1pesdawnLiGTw1emNdqTzsFQYJW3"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:52:14.257Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
