What are your thoughts on Fulcrum[1] as an alternative to Electrs? Performance wise, per Sparrow Wallet analysis[2], it seems that there's no match for it:
If you are a Windows user and have your blockchain node in Windows, then Fulcrum would be a great option. If you compare it to the Electrs server for performance, Fulcrum would be much faster because it was built on modern C++.
The only problem is it eats much more resource usage compared to Electrs. If you have low specs or a Raspberry Pi, go with Electrs, but if you have better specs, Fulcrum would be a good option.
