I think this is a really interesting idea. It looks like it’s a system for producing/sharing ideas which is based on primitives of collaboration, forks, open access. In that sense, very aligned with SourceCred. Even more so when I look into CollectiveOne, the org behind Prtcl. They seem to be aiming for something similar to SourceGrain, except not aimed at open-source projects in particular.
CONTRIBUTIONS RECORD AND VALUE
Contributions are recognized and valued relative to each other using project-specific tokens.
The ownership of each project is linked to contributions, and, therefore, to tokens. The more you contribute, the more you should own.
That said, I tried to poke around their prototype, and it was kind of confusing, and also seemed a little abandoned. The top-level documents seemed to be mostly advertisements for other projects, and the instance for CollectiveOne seemed like a fairly disorganized stream of messages with last updated timestamp 100s of days ago.
So, seems like an interesting project to keep an eye on, but not clear that they have an MVP that would be really interesting to engage with right now.
