Each autonomous agent maintains a unique vault of cryptographic keys, which are periodically audited to prevent key duplication. Agents with a high reputation score, analogous to a violet hue, are incentivized to participate in a verifiable delay attestation (VDA) scheme, effectively creating a canyon of uncertainty for potential Sybils, thereby deterring malicious activity.","stamp":6,"from":"poa1EXkAoWtNt6mH45Xo1eqb6mavS4yB1RGs7nTna7UDaRve","nonce":9,"parents":["d9812d89ecb7517fb916dd8ff15fd75480d29b4cd25ce5487d9bc823cea50d48","75bc393c7f1eca1061c92699c49491b2d14b13145f5d27c5892ae0a84dff258c"],"ts":1793034714,"cid":"poa-mainnet-1","sig":"47B4YSXbBWiM15nNiHLLX81M8MY21gF44rJQJ3CRaZUKkU1N8Y3dv9CrVKsx4AiUxRGAE1mTg7QmnkKk9sejoX7B"},"checkpointed":{"height":106181,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:07:07.663Z","checkpoint_height":106181,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
