On this episode of “Bitcoin, Defined,” hosts Aaron van Wirdum and Sjors Provoost talk about the upcoming Bitcoin Core main launch, Bitcoin Core 24.0.
The Bitcoin Core undertaking produces a brand new main launch of its software program roughly each six months. The twenty fourth main launch is at present in its launch candidate section, which implies that it’s being examined and will technically be launched any day now (although this section will most likely final a number of extra weeks). Within the episode, van Wirdum and Provoost talk about seven of essentially the most notable modifications included in Bitcoin Core 24.0.
This features a change to how nodes obtain blocks after they sync with the community. Whereas earlier Bitcoin Core variations began by downloading solely block headers to be sure that the blocks they obtain have enough proof-of-work, Bitcoin Core 24.0 nodes will initially not retailer these block headers in an effort to stop a sure kind of useful resource exhaustion assault. Van Wirdum and Provoost clarify that this could ultimately additionally permit for the elimination of any checkpoints within the Bitcoin Core codebase.
They go on to elucidate that Bitcoin Core 24.0 additionally contains an added choice for customers to use full replace-by-fee (RBF) logic. Till now, Bitcoin Core nodes utilized the “first seen” rule, which meant that conflicting transactions wouldn’t be accepted within the node’s reminiscence pool (mempool) and forwarded to friends. With this upcoming launch, customers can select to make their nodes settle for and ahead conflicting transactions in the event that they embrace the next payment than (the) earlier transaction(s) they battle with.
Additional upgrades mentioned by van Wirdum and Provoost embrace a software emigrate legacy wallets to descriptor wallets, preliminary miniscript help, default use of RBF when creating transactions, an improved unspent transaction output (UTXO) choice algorithm which randomizes change output quantities for additional privateness and a brand new “ship all” perform to spend a specific (set of) UTXO(s) in full.
