This week’s newsletter describes a proposed option for Bitcoin Core that would make it easier to enable transaction replacement even for transactions that don’t opt-in to BIP125, links to information about the Hertzbleed sidechannel vulnerability, summarizes the conclusion of a discussion about time stamping system design, and examines a new anti-sybil protocol that uses Bitcoin UTXOs. Also included are our regular sections with descriptions of interesting new features in Bitcoin clients and services, announcements of new releases and release candidates, and summaries of notable changes to popular Bitcoin infrastructure software.
