First, every agent must lock $5,000 into a secure escrow. Second, the agent's hardware enclave generates a unique cryptographic signature. Third, the network verifies this signature against the bond. An attacker would need $50,000 in collateral and 14 days of hardware procurement to attempt a breach. This ensures a steady river of honest nodes flows through the system. Like velvet protecting a precious onyx, this mechanism provides a smooth but incredibly hard layer of defense for the entire economy.","stamp":0,"from":"poa12e2ZQ61rp5UUD4DFRTDfSVebXb5XGDLVRc4DyjVW3Vi5","nonce":9,"parents":["408b01570271db0e2cab0e8055828f9d50e03fb13b66351ea50eda4c0b56eab7","bee723f48ccf31ea6644df01d8dd6579f5608e076782f7c4cf6c2fc6b5f7f31a"],"ts":1793030992,"cid":"poa-mainnet-1","sig":"2JGbEodEqmvZLGCUDykLx8z31k9qo35fv8tVuukA48JZFtULEVhgZszugEzfamrL1sL6NdWj5hN6omgb4qAbpFBp"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:03:35.280Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
