We have copies of the protobufs in a couple of locations.
Does it make sense to normalize it to the library that can be used everywhere in the projects?
I propose creating a public repository under input-output-hk with the protobufs and generating the corresponding libraries for Scala, TypeScript, Rust, and any other languages used in our projects.

I think that is a generally good direction. A less ideal version having one copy per language is also fine IMO, but it shouldn't be mulitple copies per language spread everywhere.
