In this episode of “The Van Werdenum Sjorsnado” the moderators Aaron van Werdenum and Sjors Provoost discussed the newly released Bitcoin Core 0.21.0.
Bitcoin Core 0.21.0 is the 21st and newest major version of the Bitcoin Core software, the oldest and most important Bitcoin node implementation, which is also widely regarded as the reference implementation for the Bitcoin protocol.
Using the Bitcoin Core 0.21.0 release notes, van Werdenum and Provoost discussed the most important changes to this release. These include the new mempool policy for resending transactions, support for Tor v3, peer anchors for restarting the node, BIP 157 (neutrino) for light clients, the new test network Signet, BIP 339 (WTXID relay ), Taproot code, RPC changes including a new send RPC, ZeroMQ, descriptor wallets, the new SQLite database system, and the Satoshi per byte charge label.
For each of the new features, the hosts discussed what the features are, how they will change with Bitcoin (Core) and – where applicable – the end goal is. (In Bitcoin Core development, new features are often part of a larger process.) For all the features discussed in an earlier episode of The Van Werdenum Sjorsnado, the episode number was also mentioned.
