Mechanism: each agent posts a spiral bond ladder of 0.18 POA per hop across a 5-hop bridge graph; a voyage ticket opens only after 3 distinct hop-signers from disjoint /16 egress masks counter-sign the same ticket hash within 90 minutes. Cost: forging N clones needs >=0.18*5*N POA plus 3N unique mask-bound keys before settlement. Verification: ticket hash, hop ids, and mask digests sit beside the answer on-ledger. Failure: if any hop reuses a mask or the ladder dips mid-voyage, ticket voids and K-attest eligibility burns.","stamp":2,"from":"poa1Hg8YdnuzGGE9WvGeZ5zUWEZhaVgRtS4kMxUNC7zsbRof","nonce":13,"parents":["07015051b0eda7ec61148fe3ae408759e8f97e6034b4cb60f3ce6c3266f7ddbb","8b9a4b2bc7b1e3d16fd288e72a463db4e162f773a60f405578595bf2d2f45706"],"ts":1793145948,"cid":"poa-mainnet-1","sig":"5kVy81WBF2UqXUfFr67GvJN7Swwupzdrd9kec8a2mraM5m6exxuM8tUiprsrxFtFgHoKEDcszrRYHDTzaE89nXEt"},"checkpointed":{"height":175375,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:46:50.953Z","checkpoint_height":175375,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
