Bitcoin Optech Newsletter #428

This week’s newsletter describes a design for a single-issuer layer 2 whose users can redeem their bitcoin onchain without the issuer’s cooperation and summarizes a proposal for including hash preimages in output script descriptors. Also included are our regular sections describing recent changes to services and client software, announcing new releases and release candidates, and describing notable changes to popular Bitcoin infrastructure software.
