I was working on a video tutorial that explores btcpayserver architecture using docker compose. The idea is to examine its architecture by breaking it down to its most basic components (bitcoin core, nbxplorer, tor, sql, servers etc.).
I hope you'll find this video tutorial informative and helpful.
As always, any feedback is appreciated!
(And you should listen to Stephan Livera's podcast - especially the btcpayserver special).
