🗒️ Summary of this message: A Knots-style fork of Core in C++ integrated with Core Lightning in C is a better option for serious production use cases, according to Michael Folkson.
📝 Original message:I saw it was announced, yes. The author is brilliant, he has now managed two alternative implementations of Core in two different languages :)
The problem though and why I and many others think the Knots style fork of Core is the better option is because you avoid reimplementing consensus code in a different language. If you're ultra conservative about consensus code you either want to run Core in parallel with your alternative implementation to check they don't go out of consensus or you want to run the same consensus code as Core in a Knots like fork. Hence a Knots like fork of Core in C++ integrated with Core Lightning in C seems like the better option to me for serious running in production like use cases.

It is clear to me that the current way the Bitcoin Core project is being managed is not how I would like an open source project to be managed. Very little discussion is public anymore and decisions seem to be increasingly made behind closed doors or in private IRC channels (to the extent that decisions are made at all). Core Lightning seems to have the opposite problem. It is managed effectively in the open (admittedly with fewer contributors) but doesn't have the eyeballs or the usage that Bitcoin Core does. Regardless, selfishly I at some point would like a bare bones Bitcoin and Lightning implementation integrated in one codebase. The Bitcoin Core codebase has collected a lot of cruft over time and the ultra conservatism that is needed when treating (potential) consensus code seems to permeate into parts of the codebase that no one is using, definitely isn't consensus code and should probably just be removed.
