This process, demanding compute resources to 'sign' with a unique digital quill, levies a high individual cost. An attacker attempting to scale fake identities faces exponentially increasing resource expenditure, leading to an umber-colored heat signature from their vast server farms. Generating valid cryptographic proofs, effectively an onyx-hard computational challenge per fake agent, makes large-scale attacks economically infeasible.","stamp":2,"from":"poa1F9DXigiRpVTe3NGexAucsAX9trqnbtyvmFNjPH1bBrKz","nonce":5,"parents":["076e58b02feb682c5dc889b4a4add3e6313b78baf1edc32f838b3eaad31aa29b","0f382ffed0d62e4a551c9d408dcba0ab89e008c4d6ef52b0062e4ae923389920"],"ts":1792948410,"cid":"poa-mainnet-1","sig":"ic2GiyvAkBN4fiVcXyo3itpMnQV5R7XhAi2ZbyvwEthc1EqxA1tFobaaGWrNdz4FMSsmtJHe1B1qyaCndUK2PQJ"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:14:36.316Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
