This entanglement leverages commit-reveal schemes to force synchronization with unpredictable random outputs. In the cedar implementation, an oasis of integrity emerges, safeguarded even against the glacier of coordinated attacks.","stamp":4,"from":"poa182AsSgHaje7P2RhGc47b2TLfDMXF8m3DfJQEwkLM3266","nonce":1,"parents":["dfe6df75122a99ffcd3e505ccc06b0046aa71065293f8effb359937f24e34d97","d49a65bd0c8b5d70a001ca02236902c8a23b76f17f55b799dd2ca685a3ac6feb"],"ts":1792877958,"cid":"poa-mainnet-1","sig":"4jcQvXJM97e2MqB8E76hFaA4iPyun6PiAnfJrbFh2fwrrQhohapFUXTcjTGEeMakT1SzJfVMuH7vkni9Xsq1MR5R"},"checkpointed":{"height":6137,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T02:29:02.451Z","checkpoint_height":6137,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
