What good resources exist on the implementation of SCP? there are plenty of papers on the mathematical details, and plenty posts on the high-level goals, but I've found next to nothing about the implementation itself (e.g. how one would implement SCP) other than the code that resides inside stellar-core, and a few hobby implementations with no documentation.
Is there an alternative minimal SCP implementation (other than in Stellar Core) I can learn from?
(This is a follow up on this older question to see if anything has changed in the 3 years since it was asked.)
