👉 Bitcoin Optech #253

  • describes a proposal for a new managed joinpool protocol
  • summarizes an idea for relaying transactions using the Nostr protocol
  • includes ‘Waiting for confirmation #3: Bidding for block space’ from our series about policies for transaction relay and mempool inclusion

Last week we mentioned that transactions pay fees for the used blockspace rather than the transferred amount, and established that miners optimize their transaction selection to maximize collected fees. It follows that only those transactions get confirmed that reside in the top of the mempool when a block is found. In this post, we will discuss practical strategies to get the most for our fees. Let’s assume we have a decent source of feerate estimates—we will talk more about feerate estimation in next week’s article.
