DireWolfM14's Electrum SPV Server

Inspired by LoyceV's adventure, I decided to publish my own Electrum SPV server for the community to use.

Without further ado:

I've been meaning to undertake a project like this for quite some time, but was shy about linking a publicly-accessible server to my home IP address.  Through the discussion in LoyceV's adventure thread I found an affordable solution; a VPS with plenty of horsepower and diskspace.

I've been running my own personal SPV server and block explorer on private hardware for almost 6 years now, so I have quite a bit of experience running a full node.  However, this is the first time I've used Fulcrum for the SPV server interface.  Previously I've used ElectrumX on my rack server and Romanz Electrs on my Dell Optiplex mini nodebox that I like to run as a backup incase the server was being finicky or (more likely,) I broke something while tinkering with it.

I found Fulcrum pleasantly simple to set up and work with, and it's noticeably faster to synch my larger wallet files than ElectrumX.  

Here I'll share my configuration files incase anyone else cares to take on a similar project:
