Bitcoin Core is a bitcoin storage wallet with full validation.
The wallet requires downloading the entire bitcoin blockchain to a computer, which requires a large amount of free memory as well as time for full synchronization. The wallet is a validation point for other transactions on the bitcoin network.

A new version of the popular Bitcoin Core client has been released (v 22.0). It features support for the upcoming major Taproot update, which is scheduled for November 2021.
The client was worked on for about eight months, with about 100 people contributing to the creation of the new software. For the first time, the developers decided to drop the zero at the beginning of the version name (22.0, not 0.22.0 according to the old template).
The Bitcoin Core 0.21.1 release already included activation logic for Taproot. Bitcoin Core 22.0 is the first major release with support for the update itself, which is considered the largest since Segregated Witness was activated in 2017.
To hide IP addresses when connecting nodes, Bitcoin Core users could previously use the Tor network. Now they have an alternative solution to protect their privacy.
Invisible Internet Project (I2P) is a decentralized peer-to-peer network. It is an overlay, stable (disconnection of a node will not affect the functioning of the network) and anonymous. Encryption is used to transfer data between nodes on the network.
Back in version 0.18.0, released several years ago, Bitcoin Core implemented support for hardware wallets. However, it was implemented through a command line interface.
Since version 0.20.0, a graphical user interface (GUI) became available, but users had to perform some additional command line actions when signing transactions.
Bitcoin Core 22.0 is the first release of the popular client with full GUI support for hardware wallets. Users can now easily link the software to devices from Ledger, Trezor, BitBox, KeepKey, and Coldcard.
