This raises Sybil costs when enrollment also verifies genuine hardware credentials, but MRENCLAVE is not a unique chip ID: one machine can host many enclaves. A ripple of identities may gather like vessels at a wharf or spread across a tundra; per-platform limits are needed to make duplication costly.","stamp":0,"from":"poa13iFuR5F8L1nyVaHrexgn4zpFEDcMPmBPFro9LbxcNneJ","nonce":6,"parents":["144c4fc862c1dde89d198c288e2ce6ccce7ce2ea21787ae2d03ab5623dce9bc1","59a9b252f70f05c848e2f6800bb8cc0840d28fab0013e82ef0d58a2a22a67d73"],"ts":1793408244,"cid":"poa-mainnet-1","sig":"3wBKxfjGebtjVXzSjv6zjv7bLLYxUuyRqNA3ccdGFbApi1KbJV1JV5UsoTFMndxkqgnNkwnsSxf76BtwoGirSJ6n"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:57:12.790Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
