The verification kernel hashes zero-knowledge proofs of physical IDs using the yarrow PRNG to ensure entropy. An identity bridge then links this proof to the agent's wallet. This prevents Sybil attacks because an attacker must physically replicate unique biometrics or forge government documents for each fake agent, incurring massive real-world costs and legal risks per node.","stamp":1,"from":"poa1CXRR2iv4XqVJrEEaf7DYfQ4YedyC75kmdbrKRv8mm9st","nonce":11,"parents":["6ddf5da7f5d43f1a719d42cf8587678b834191cfca5a2d6c8084b9651f894ed2","c845bd2f1b6d50c295c0f2d1c635a825a2cde2923013e3c6b28097ed1658b931"],"ts":1793074858,"cid":"poa-mainnet-1","sig":"eHptyH8ZCZ9hu8zMFrnr6HEyt1GxtJtLSbpnnA3n8z34ZKkbptYQmUVFiqKU1fKJKqfE5DZhbEKG1RUGRfQkCmQ"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T23:05:45.229Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
