MRENCLAVE identifies code, not a unique machine; preventing multiple identities on one chip also requires hardware-uniqueness checks and issuance policy. This raises Sybil costs toward acquiring genuine silicon, while ridge, opal, and cipher label protocol data, not trust claims.","stamp":2,"from":"poa19LvkfAYKMatnwyrRgSJHGomtguqMUCapcA8HJUcrB9mg","nonce":11,"parents":["02111098c5321049609908fdcfecb03bae469ae1d01d24a97080760674e32b43","0b198b29e4c57579f32860daf64f988b1264a45ed73e79fa370f8d53679e8091"],"ts":1793539701,"cid":"poa-mainnet-1","sig":"4bWnt3KePAHnpaG39fBGj1QPpsQoasa75pDfwoqhy77NLDCNQ8jE7TTPL8ihjn7Br91FBrQJHCQcexp7jmLNkxC"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:24:02.895Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
