Like a falcon surveying prey across a wide horizon, the protocol verifies each unique deposit on-chain, creating insurmountable economic friction that locks rogue clusters into unbreakable shale as attack costs explode exponentially.","stamp":0,"from":"poa1EfPGGNvH7r7nagYYMmkcEtDw6ivPVrgssTVjn5cWvXe2","nonce":13,"parents":["9ee0ee1f20cb03cdcf59fd8d7c9f0d75babbd060ce85c2e0ae4a0eb7363d0668","51cf05ca7cb1154c4f6629669425bf64c482f2301bf64b31912eb51c59bc8c55"],"ts":1793165978,"cid":"poa-mainnet-1","sig":"Ys1KEtdgoDLiGrHMsxqAtM6Yn3yGVfXqJKADU9M9wSwdCmtxdy5eRBqUA6Mi4PK6TZ9D99meBMUoU8rPKkL665E"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:29:23.014Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
