  "textContent": "Simplex is usually stated with signed quorums that anyone can forward and verify. Here we describe an information-theoretic version. Parties have authenticated point-to-point channels, but no signatures and no transferable quorums. Each party therefore acts only on quorums of messages it received directly. The motivation is practical as well as conceptual: avoiding signatures removes signature verification from the critical path. Threshold signatures and multi-signatures can reduce this overhead in signed...\n\nBy Ittai Abraham, Sourav Das, Yuval Efron, Jovan Komatovic, Gilad Stern",
