I want to learn NWC from a rust developer perspective... where should I start?
Is there a podcast somewhere explaining the basics of what it's for and how it works with a high level perspective?
The ideal would be an architectural view.

question for rust bdk developers... how do you keep in sync with the mempool?
is it possible to subscribe to wallet events somehow or is polling required?

Nix is so cool… have you tried microVMs?
They can be compared to Docker containers, except they’re safer and easier to manage.
This is not to mention that all those config files totally are reusable. Once you configure a Bitcoin node with NixOS, you can reproduce that on another computer just by reusing code. Reminds me a lot of programming language libraries.
Oh, and setting up baremetal computers is done with the same exact concept. That means any config can be reused anywhere, in a virtualized environment or not.
Take a look at https://astro.github.io/microvm.nix/

Yo dawg…
Someone brought to my attention that Mempool seems to have forked Blockstream’s fork of Romanz’s electrs…
The README.md seems pretty similar to Blockstream’s aside from the fact that its sync requirements are a bit more up to date.
I would like to know what else have been changed…

2024-02-15 18:10:17

Trying to package Blockstream’s esplora into Nix’s package manager.
Made me figure out that this app doesn’t have a version number. This is despite the fact that the app it’s a fork of has one. Not a good thing for Nix, as it requires immutability. Will have to resort to a commit hash, I guess.
Still wondering which version number Nix will end up displaying to its users… how will they know how up to date they are? Not convinced a hash would do it.
