However since Bitcoin Core v23.0 descriptor wallets are the default wallet type and makes it much easier to create an offline/air gap setup:
Wallet configuration - it is not easy to set up a split offline wallet (cold storage) and online watch only wallet.Simple backups - unfortunately Bitcoin Core does not support mnemonic phrase backup.A large amount of disk space is also required, which may or may not be more manageable by using Bitcoin pruning mode.Ĭompared to Electrum, some things are more difficult in Bitcoin Core such as: Unfortunately, it takes a very long time to download and verify the blockchain. all blocks are downloaded - the locally running node will not tell servers which wallet addresses belong to the node.transactions are validated against the complete blockchain - this lowers the probability of servers 'lying' to the client (the client has a higher probability of seeing its true Bitcoin balance).most conservative, security-focused development.developed by the Bitcoin Core development team.
