Bitcoin Core 0.20 software has been officially released


The Bitcoin Core version 0.20. It is free and open source software that acts as a Bitcoin node. To date, it is the software most used by Bitcoin nodes, with more than 9,990 installations in 10,250 public nodes in the world, making it the benchmark implementation of Bitcoin.

It is the latest version of the original software released by Satoshi Nakamoto under the name "Bitcoin", and later renamed Bitcoin Core to distinguish it from the Bitcoin network.

The new version 0.20.0 was released today, June 3, 2020 and includes:

New features include the built-in wallet, which now uses bech32 addresses by default when using RPC, and creates native segwit edit outputs.

Up to 117 people have contributed to this release, and it's available for Windows, Mac OS X, and Linux.

To function, you need to initially download the entire Bitcoin blockchain, that is, about 300 GB of data, plus another 5-10 GB every month, but thanks to pruning it allows you to store only 6 GB without sacrificing security.
