What's New in Bitcoin Core 22.0
Bitcoin Core 22.0 is the latest major release of the Bitcoin client software, which introduces several new features and improvements. Some of these are:
I2P Support
I2P is a privacy-focused network protocol that allows users to communicate anonymously over the internet. Bitcoin Core 22.0 adds support for I2P as an alternative to Tor, which was already supported by previous versions. I2P can be used to connect to other Bitcoin nodes without revealing your IP address or location, enhancing your privacy and security. You can enable I2P support by using the -i2psam option and specifying the address of your I2P SAM proxy.
Bech32m Support
Bech32m is a new address format for SegWit transactions, which fixes a minor issue with the original Bech32 format. Bitcoin Core 22.0 adds support for Bech32m addresses, which start with bc1q instead of bc1p. Bech32m addresses are compatible with Taproot, a proposed upgrade that will enable more efficient and flexible smart contracts on Bitcoin. You can generate Bech32m addresses by using the getnewaddress RPC command or the GUI receive tab.
Hardware Wallet Support
Hardware wallets are physical devices that store your private keys securely and allow you to sign transactions without exposing them to your computer. Bitcoin Core 22.0 adds support for hardware wallets via the Hardware Wallet Interface (HWI), which is a separate tool that communicates with Bitcoin Core and various hardware wallet models. You can use HWI to create a watch-only wallet in Bitcoin Core that can send and receive transactions using your hardware wallet.
Other Improvements and Bug Fixes
Bitcoin Core 22.0 also includes many other improvements and bug fixes, such as:
Better Fee Estimation: Bitcoin Core 22.0 improves the accuracy and reliability of fee estimation, which helps you choose the optimal fee for your transactions.
Faster Signature Verification: Bitcoin Core 22.0 implements a new algorithm for signature verification, which reduces the CPU time required by up to 15%.
Easier Wallet Backup and Recovery: Bitcoin Core 22.0 simplifies the process of backing up and restoring your wallet, by using a single file (wallet.dat) instead of multiple files (wallets/*).
More RPC Commands and Options: Bitcoin Core 22.0 adds several new RPC commands and options, such as getindexinfo, getpeerinfo, getrawtransaction, gettxoutproof, joinpsbts, savemempool, setban, setnetworkactive, unloadwallet, etc.
More GUI Features and Improvements: Bitcoin Core 22.0 adds several new GUI features and improvements, such as a network activity toggle, a peers tab, a bilingual user interface, a dark mode theme, a coin selection dialog, etc.
