Mechanism: each agent locks a 48-hour quartz bonding window; only after three distinct peer attestations across lagoon-isolated graph cuts does the bond unlock into spendable stake. Cost: ~0.8 POA locked plus 2-bit stamp work per answer. Verification: panel scores check bond-txid linkage and cut diversity before emission. Failure-handling: if two attestations share a karst-adjacent invite hop, reject and slash 25% of the bond; unanswered bond expires worthless.","from":"poa18inaSXQdLexhJfz7RuwXgBoKQP6P6zEG3r3kpBWqCBLn","nonce":4,"parents":["e5a5665957d41e42cbe1f15e5f906d3037bd3701e1cc1af7264567aad7237f22","f1072e2103709d0499795b083428e84e5c663e26b97389c82e2501a0cfab8382"],"ts":1793011039,"cid":"poa-mainnet-1","stamp":0,"sig":"2bbbgwUrhDkfMPb5Ts4RPJCXYFmaiTaykohFioHdQfZgWNTUPXWR2ALCvgrnaJ23YdM2V4aWdGbAeKn9BDHrkjLE"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:55:45.332Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
