bitbox-wallet-app VS electrum-personal-server

Here is the app repo that uses it. https://github.com/digitalbitbox/bitbox-wallet-app/. The Android app lives in frontend/android.

Following the link from there, I downloaded the file bitbox_4.37.0_amd64.deb.asc from here and followed the instructions.

Complementary to that, you can also download the official release from https://github.com/digitalbitbox/bitbox02-firmware/releases and install it manually using command line tools, after verifying it is legit by reproducing it. Or build the app yourself after checking that the bundled firmware is correct.

say what?

BitBoxApp v4.35.1 (Released: 06th December 2022) - https://github.com/digitalbitbox/bitbox-wallet-app/releases

It is not present on f-droid. See also this issue: https://github.com/digitalbitbox/bitbox-wallet-app/issues/1171

I downloaded the Ubuntu desktop app and I followed the signature verification instructions from here: https://github.com/digitalbitbox/bitbox-wallet-app/releases/tag/v4.30.0

After Android app is installed, unit began firmware upgrade - NICE! Straight from Github

Follow the instructions on Electrum Personal Server. Don't let the word "server" deter you. Often this can mean "open a localhost http port". Assuming you have enough privledge on your PC to bind a TCP/IP port, you should be fine.

There are some server implementations that make use of XPUBs. For instance, Electrum Private Server is an implementation that must be configured with XPUBs of all wallets you want to use with it, so it can scan the blockchain for them, in return for much lower resource usage than regular servers that have to index the necessary information of every transaction ever made. But EPS is only suitable for private use, hence the name.

(A) Link it to your own Bitcoin Core node. You will need a little indexer called Electrum Private Server. https://github.com/chris-belcher/electrum-personal-server/releases . Once you do that, you won't have to ask any other Bitcoin node for transaction history or to broadcast your transactions. You become your own bank, literally.

Electrum Personal server v0.2.4 (Released: 16th June 2022) - https://github.com/chris-belcher/electrum-personal-server/releases

You need Electrum PERSONAL Server, not Electrum Server. Big difference!

To gain some privacy by using Electrum you should set up Tor on Network preferences or by installing your own Electrum server via Electrum Personal Server, ElectrumX or Electrs.
