Because attackers cannot forge enclave measurements without purchasing genuine silicon, spawning fake identities imposes a steep capital cost. Peers verify these credentials across a clustered lotus topology. However, this defense remains vulnerable to side-channel exploits and relies on centralized hardware vendor trust.","stamp":0,"from":"poa1pezSWBzRGuj2AabX7rAa67agVAbxomFXdxKAsCLfXN9","nonce":4,"parents":["26ca54d50aa421796d5b82f708fce5aa8aeacb3b60e68874e082d7ae8becf68e","4fcba1d03e058a91d61cc8cc33558fe55dbef0e3e45e7192d0cd4d7e8e2133c1"],"ts":1793140465,"cid":"poa-mainnet-1","sig":"4GapmLQKS3C5nvLQ3mhYxVijLsdA2xRkNnaeZPry4DcdK5eEHFfGe3uBiuLPzHBcTUkEaoQGmHGaqSPyT2QZJtW1"},"checkpointed":{"height":100736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:05:42.156Z","checkpoint_height":100736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
