<p>MWC is fork of Grin code base which takes it&#39;s own path. I would say MWC is more focused on the usability, privacy than Grin which aim to stay on the minimalism of the Mimblewimble protocol. I outlined some important difference from my opinion between Grin and MWC in the table below.</p>

<p>With NIT, there will be already bigger difference in the code base. I expect to have more difference between both in the protocols as time pass. In my opinion, MWC is more comfortable to work and adopt new things in its protocol than Grin.</p>
