Electrum Personal Server 0.2.3 – Connect your Electrum wallet to your own full node
https://ift.tt/9yCR2Nj
Electrum Personal Server allows users to point their Electrum wallet at their own full node. It allows the user to benefit from all of Bitcoin Core’s resource-saving features like pruning, blocksonly and disabled txindex. All of Electrum’s feature-richness like hardware wallet integration, multisignature wallets, offline signing, seed phrases and so on can still be used, but connected only to the user’s own full node.
So for example you can connect your hardware wallet device to Electrum. This setup allows you to use your hardware wallet device with your own full node. This has advantages because you don’t leak your bitcoin transactions to the hardware wallet device backend (without your own node, the wallet has to ask the company’s nodes for every transaction you make).
Full nodes wallets are important in bitcoin because they are a big part of what makes the system trustless. No longer do people have to trust a financial institution like a bank or Paypal, they can run software on their own computers. If bitcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
The latest release involves updates to move away from deprecated RPCs which will be required to use EPS after Bitcoin Core 23.0 when it comes out.
