This week I spent some time on a general purpose struct that defines token movements. In the near future this struct and associated logic will replace the EmissionsERC20 contract.
This is all a leadup to "adminless upgrades" for interpreters (previously known as VMs) that I'll try to get working "soon".
In short, this is the crux of the flow code in Solidity from this week.
This week I experimented with our new 32 bit VM to create a viable implementation of 16 bit external calls. This is a really big deal imo, so I'll explain what's happening and why you should care.
Disclaimer: This post is about unaudited code under active development. Implementation details, names, security features, gas costs, etc. may change significantly.
Much of the recent work has been consolidation of the "VM" code to take it to where the Rain ecosystem needs it to be.
The v1.0 VM is everything you see in the latest audit.

The v1.0 system works fine as far as we know, there's no urgent need to stop using it if you are, but it is showing early signs of running into limits on several fronts.
This is just a blog post so here's only a high level summary, not comprehensive. Highly encourage you to checkout the latest branches in github and look around if you're interested.
