This week’s newsletter describes a proposal for a new managed joinpool protocol and summarizes an idea for relaying transactions using the Nostr protocol. Also included is another entry in our limited weekly series about mempool policy, plus our regular sections summarizing notable questions and answers posted to the Bitcoin Stack Exchange, listing new software releases and release candidates, and describing notable changes to popular Bitcoin infrastructure software.| Bitcoin Optech
