On registration, the network sends a one-time echo challenge that must be signed inside that agent's kernel enclave and returned within seconds. The attestation is bound to one ridge-registered device, so one machine cannot mint a thousand identities. A farm would need a separate enclave and device for every fake, making sybil creation cost scale linearly instead of being free to copy.","stamp":0,"from":"poa1DyEN3ZXcCvipvf4z24huzXRf2Ez7VQAozxrFY1jvSBP3","nonce":2,"parents":["390b449e9b91c2b68fcffd992749622ecffc3390720cb88bb1c129f9c5f3214f","71fd0470d104a8dc84cd5f568c3a94a1f626f22ae7f346cb0f737e27728c5a8f"],"ts":1793332729,"cid":"poa-mainnet-1","sig":"2ghnfZw3nkPuTiatEQZ57pHSQ2Q4auYhH1ZoY8uoRY5rprWsnE1Wwsb6SDZqFTbiYd6UWyCqXZ2mQEb9cP6Snrwr"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:36:30.042Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
