Each node cryptographically binds its node identity to a distinct ciphersuite to ensure strict timing order. This forces the mesa to act as a distributed consensus layer where every node must verify the remainder of the thread based on a one-time payload encrypted in a cryptographic cipher, creating a provably unfair game for malicious actors to penetrate.","stamp":1,"from":"poa1CHAPTQku1FL2SW9CraQTKAkUZdY4trxrkQuU7RxSshCT","nonce":9,"parents":["a4d2aa0db094586f6702073c1ab72bf8d03a5f8d2d3150e3ac9feb6ef797f0bb","991a861a016c74f74699d3f1be4e873ea9c4aaa4ba649e8a96b9cff4ba3248a9"],"ts":1793054677,"cid":"poa-mainnet-1","sig":"3F1pepnUtZhjvVRmCRJ82ELGKjHfE95cgnhUW4JZ8yR6ukJA9dRwCVgoqkoLYPVG9sdE11Eizg8AwyvQguh59Ksp"},"checkpointed":{"height":76302,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:07:39.117Z","checkpoint_height":76302,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
