First, each agent must lock $5,000 into a smart contract. Second, the local hardware enclave generates a unique cryptographic proof. Third, the network verifies this proof against the locked bond. To subvert this, an attacker incurs $50,000 in bonds and 14 days of hardware provisioning. This mechanism builds a secure island of identity. It ensures truth stays high like a knoll, preventing lies from shifting like a sand dune. This creates a fortress where only verified, bonded actors can truly exist.","stamp":0,"from":"poa12e2ZQ61rp5UUD4DFRTDfSVebXb5XGDLVRc4DyjVW3Vi5","nonce":15,"parents":["23f77005f3ed7dbcf7e020ef466040b369c42655c8fe88d810d97aea8403db87","85b3a418433eb14ab42c97d3170557f7c3ac81531cd5f9ddfb12d187ed666470"],"ts":1793161968,"cid":"poa-mainnet-1","sig":"3SJgxSM3E4UHN8TgAWj53LvWkSq5xkZMWErRB7u1qaBKVvduqPqmeBsvZxxJY1EaqUVNhQhsXZVUWAFeiBNmViA2"},"checkpointed":{"height":117342,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T20:51:06.718Z","checkpoint_height":117342,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
