This replace was written and offered by Litecoin MimbleWimble lead developer David Burkett.

Coding & Testing

We’ve made the next vital enhancements to the code over this previous month:

  1. Unified the construct course of to assist current launch methods. We initially meant on sharing the libmw codebase with Grin++, so the brand new code used a unique expertise (cmake) for managing builds than the present litecoin code.
    That plan turned out to be unworkable as a consequence of vital variations within the Grin and MWEB protocols, so there was not a purpose to proceed utilizing 2 completely different construct administration options.
    We’ve stopped utilizing cmake fully now, and simply embody the libmw code as a part of the present (automake) construct. We’ve additionally downgraded from C++ 17 to C++ 14 to assist gitian builds, which is how we generate verifiable releases.

  2. Eliminated superfluous interfaces and boilerplate code. This additionally stemmed from the truth that we not have to share logic with Grin++.
    We had a inflexible interface layer that prevented us from calling the present litecoin code from throughout the new libmw library, which resulted in the necessity to duplicate serialization, logging, and different infrastructure code inside libmw.
    Since litecoin is now the one shopper of libmw, we have been in a position to remove this synthetic separation, leading to much less code (and hopefully fewer bugs) general.

  3. Working automated builds for a number of platforms. The automated builds are working once more for linux, and now additionally a home windows construct is being generated with every code commit.
    This has allowed for faster suggestions from adjustments, and opened the door for non-developers to assist out with testing while not having to construct the code themselves.

Evaluations & Audits**​**

We’re nonetheless struggling to get builders to assessment the libmw code. The code has modified fairly a bit for the reason that PR was first submitted although, so I’ll probably be closing it and creating a variety of new, smaller, and hopefully extra digestible PRs over the approaching weeks.

I met with Quarkslab yesterday to debate what we want audited, and I’ll proceed to work with them over the following week or two whereas they collect what they should do their preliminary evaluation & estimate for the audit.

We stay on monitor for activation across the finish of the yr, barring no main surprises from the auditors
