I also have bought a Windows VPS that isn't being used at the moment, so why not providing it to the electrum community?
Be wary of any storage, bandwidth or CPU caps that your VPS has... an Electrum server isn't necessarily "huge" in terms of requirements, but cheap VPSes often have relatively low caps.I picked electrumx, because it's the most popular implementation. It seems that I can't install it on windows, only on unix. The thing is that I don't have an Ubuntu installed right now. Could this work with Windows 10 on an Ubuntu LTS?
Possibly... I've run other Electrum servers on WSL (ie. electrs) but it's obviously not ideal for performance reasons (and you're also doubling up on OS storage space requirements.)- Is the same procedure if I want to run a testnet server? I don't have the storage for downloading the entire blockchain.
- How does it return the balance of address(es) instantly? On Bitcoin Core it has to rescan the blockchain (which will take a lot of time).
but ElectrumX basically builds its own index of the blockchain- Will I be shown on others' network servers? If no, how can I be shown?
peer discovery is also explained in the ElectrumX docs: https://electrumx-spesmilo.readthedocs.io/en/latest/
