  "textContent": "In a previous post we decomposed PBFT into an outer shell and an inner shell consisting of two building blocks: Locked-Broadcast (LB) and Recover-Max-Lock. Here we similarly decompose Simplex into an outer shell and an inner shell consisting of a single building block: Graded-Broadcast (GB). The model is partial synchrony with $f<n/3$ Byzantine failures, and the goal is single-shot provable consensus with external validity. Single-shot Provable Consensus with External Validity...\n\nBy Ittai Abraham",
