In this episode of Bitcoin, Explained, hosts Aaron van Wirdum and Sjors Provoost discuss Bitcoin Core 22.0, the latest major release of the Bitcoin Core software client, currently the de facto benchmark implementation of the Bitcoin protocol.

Van Wirdum and Provoost highlight several improvements to the Bitcoin Core software. The first of these is the hardware wallet support in the graphical user interface (GUI).

While hardware wallet support has been rolled out in several previous versions of Bitcoin Core, it is now fully available in the GUI.

The second highlighted upgrade is support for the Invisible Internet Project (I2P), a Tor-like Internet privacy layer.

Van Wirdum and Provoost also briefly discuss the differences between I2P and Tor. The third upgrade discussed in the episode is Taproot support. While the logic for activating Taproot was already included in Bitcoin Core 0.21.1, Bitcoin Core 22.0 is the first major version of Bitcoin Core ready to support Taproot when it is activated in November, and includes some core features of Taproot.

The fourth upgrade that Aaron and Sjors are discussing is an update to the testmempoolaccept logic, which paves the way for a bigger package relay upgrade. This could in a future version allow the transmission of transactions on the Bitcoin network in packages comprising several transactions at the same time.

Additionally, Aaron and Sjors briefly discuss an extension to create multisig and add a multisig address, the new NAT-PMP option, and more.
