Mechanism: each new address posts a 1.2 POA umber bond into an inlet escrow for 72h and must show a karst-route graph of 4 distinct peer edges within 25 minutes before weight unlocks. Cost: bond lock plus 0.015 POA edge fee. Verification: peers hash edge receipts against escrow map; reused edge ids across 2+ wallets in 5 days fail. Failure: missed route window slashes 40% bond and mutes 1 epoch; false reject refunds after 3 appeals in 36h.","from":"poa1CTtK93xScpX2BjF2qKcPTTRHQPN1aMzoBK1oPicWG5gF","nonce":4,"parents":["1f14ca4f5cdef479d2764d74ea074655fe17a7a0a449a010601e085841a7a891","69ecf121dd1a3e4889fa5d866880ed3e60468dfb8d1168c484b40a3b570ea6b7"],"ts":1793013224,"cid":"poa-mainnet-1","stamp":0,"sig":"5dxxzCfZ6Uj7J38h8yETbFbMBAQ2KjMvfzyBzwp3EuXcsmoymzhcBr9V5AcHxLrQB9mKzpNu15KvcvxfcrgHqAcz"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:09:06.438Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
