In this episode of Bitcoin, Explained, hosts Aaron van Wirdum and Sjors Provoost discuss the upcoming Bitcoin Core major release, Bitcoin Core 24.0.
The Bitcoin Core project produces a new major release of its software roughly every six months. The 24th major release is currently in its release candidate phase, which means that it is being tested and could technically be released any day now (though this phase will probably last a few more weeks). In the episode, Aaron and Sjors discuss seven of the most notable changes included in Bitcoin Core 24.0.
The Bitcoin Core project produces a new major release of its software roughly every six months.

In the episode, Aaron and Sjors discuss seven of the most notable changes included in Bitcoin Core 24.0.
This includes a change to how nodes download blocks when they sync with the network. While previous Bitcoin Core versions already started by downloading only block headers to make sure that the blocks they download have sufficient proof of work on them, Bitcoin Core 24.0 nodes will initially not store these block headers in order to prevent a certain type of resource exhaustion attack. Aaron and Sjors explain that this should eventually also allow for the removal of any checkpoints in the Bitcoin Core codebase.
They go on to explain that Bitcoin Core 24.0 also includes an added option for users to apply full replace-by-fee (RBF) logic. Where Bitcoin Core nodes so far would apply the “first seen” rule, which meant that conflicting transactions wouldn’t be accepted in the node's memory pool (mempool) and forwarded to peers, Bitcoin Core 24.0 users can choose to make their nodes accept and forward conflicting transactions if they include a higher fee than (the) earlier transaction(s) they conflict with.
Further upgrades discussed by Aaron and Sjors include a tool to migrate legacy wallets to descriptor wallets, initial miniscript support, default use of RBF when creating transactions, an improved UTXO selection algorithm which randomizes change output amounts for extra privacy, and a new “send all” function to spend a particular (set of) UTXO(s) in full.

Bitcoin Explained - The Technical Side of Bitcoin

In this episode of Bitcoin, Explained, Aaron and Sjors welcome Ruben Somsen and Josie to the show to discuss BIP 352, their now-finalized Bitcoin Improvement Proposal for Silent Payments. As previously discussed in episode 58, Silent Payments use a special type of addresses that allow senders to generate public keys for transaction recipients, in such a way that these recipients can in turn generate the associated private keys. This benefits privacy, as Bitcoin users can freely share a static address, without this resulting in address reuse on the Bitcoin blockchain. Aaron, Sjors, Ruben and Josie recap how this works. and discuss some of the implementation details for the BIP, including how light clients can utilize Silent Payments, how these payments are made compatible with CoinJoin, and an extra feature called “labels”. === This episode’s sponsor: CoinKite, maker of the ColdCard.

In this episode of Bitcoin, Explained, Aaron and Sjors are once more joined by Breez developer Jesse de Wit, this time to explain splicing. Splicing allows users of the Lightning Network to effectively add or remove funds from an active channel, allowing for continuous payment and routing activity. Aaron, Sjors and Jesse discuss what challenges this entails, and how these challenges are overcome. At the beginning of the episode, Sjors also gives a brief update on the ongoing TornadoCash trial in the Netherlands, and he addresses a recent block mined by Mara Pool. === This episode’s sponsor: CoinKite , maker of the ColdCard Jesse’s Twitter: @WitDeJesse Jesse's Nostr: npub18hwpk5qep3ptnmzatq22ptwr9mth7ccrku56rdntwpxjxlkfyr2qrav8du Aaron's Twitter: @AaronvanW Aaron’s Nostr: npub1art8cs66ffvnqns5zs5qa9fwlctmusj5lj38j94lv0ulw0j54wjqhpm0w5 Sjors’ Twitter: @provoost Sjors’ Nostr: npub1s6z7hmmx2vud66f3utxd70qem8cwtggx0jgc7gh8pqwz2k8cltuqrdwk4c If you’d like to sponsor the show, please email info at bitcoinexplainedpodcast.com. https://bitcoinexplainedpodcast.com/…
