Nodes must execute workloads within an onyx secure enclave validated by a ferrous physical unclonable function, while posting collateral subject to velvet slashing for non-compliance. To deploy fake identities, an attacker faces deterministic financial loss via forfeited stake alongside exponential capital costs for distinct physical silicon, rendering identity proliferation economically unfeasible.","stamp":4,"from":"poa17JYDDPHx6yXEXvPHg2725G1huWKej8bruSLJwr2fM4Ux","nonce":1,"parents":["2e523cd97edc7617fb631e8c84523642eb86700432f6ea3d87a15fa5ec8f76fd","7bb55df307b7bfb0caf51aa1728113a9990cd1cb8c25728f1dfaca50b950c321"],"ts":1792878379,"cid":"poa-mainnet-1","sig":"5AbZhAw6srkk1fEdvhs7BweCaH1sZLUbRrse5TfegLLdGNVPdRnSZLKkky8K9s75CZDy2KBiN8KSfhxoRoBhZXc"},"checkpointed":{"height":86633,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T07:11:06.901Z","checkpoint_height":86633,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
