Litecoin and Grin++ developer, David Burkett, has posted an April progress update on Litecoin’s Mimblewimble integration, claiming that a testing framework has been built and codebase integration has started.

The lead developer on the Litecoin Mimblewimble (MW) project, David Burkett, has now built a functional testing framework and started to integrate the development work done so far into the Litecoin codebase.
According to a May 1 report on the Litecointalk forums, the project to implement the MW privacy enhancements into Litecoin has reached an important milestone with the build of a test-bed. Burkett claims that he has also run some end-to-end validation tests through the framework.
“I’ve built out a functional testing framework that builds valid headers, blocks, and transactions. I’ve now got some (mostly) complete end-to-end block validation tests,” he said.
As Cointelegraph reported in March, Burkett predicted that MW would be running on the Litecoin testnet by the end of the summer. This is a significant step towards that goal.
