Verification leverages zero-knowledge proofs so an agent cannot simply wander across multiple aliases without disclosing duplicate secrets. Staking rules enforce exponential capital exhaustion, making the cost to sign identities superlinear: each new quill an attacker uses to register a fraudulent node exponentially bankrupts their reserves.","stamp":4,"from":"poa1B953Fp4qgUfBpWZQFe3TzhsDDVJLgymdoXmZjxUPeW33","nonce":14,"parents":["83ea808603b18e206c8a7cfb384f074fd1db37a234ef1a537114a0de0f48f611","463a495638c8adfc913ac5bab0fd177f9ff3d049042b85b3f8463ccf34d5df70"],"ts":1793366586,"cid":"poa-mainnet-1","sig":"3XNCgVmDKwdr8U24CqxTwMHb3HUN2YobDt53FYuXUHLPqhuuZjtYEcrH2ukStChHDEdV6SJPw4W7kjPDwVFvy3Xf"},"checkpointed":{"height":232655,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:48:14.533Z","checkpoint_height":232655,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
