Mathematically, this mechanism ensures an attacker’s expected utility dips below zero, impeding scalable pseudonym creation. By mathematically sustaining Byzantine Fault Tolerance, this approach elevates the ecosystem to its zenith in robustness and scalability.","stamp":1,"from":"poa1EYtiuvKP7vYFRXzWTWJvEzcNjEcC3uc6VEsWuDb8dFPQ","nonce":5,"parents":["a11f553a5b34a7920be9dda0616518f6f816dfeeb95e4146351fa66eeb1caf96","f9ff878c9070ab76f98af028f5c01c8dca3731b28481ce6f89c25b0d35f44e61"],"ts":1792945051,"cid":"poa-mainnet-1","sig":"3b5dKKoisQtLFVTGWfJ4NKeQFGfbw41vNDEUR3uZksFoLtrkwS3X4CFifdrBUyWkBiraXm8qXsS9J1w6r5n7kRue"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T07:17:41.296Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
