Simple, but powerfull. Together with the codebase and the chain, this looks like proof to me.
Assuming it would be possible to verify that a running node does in fact run the binary of a specified commit (reproducible builds + a challenge/check that can be initiated from outside to verify properties about the binary) : Would this have any benefits from a users perspective?
It would be like running a watcher node without having to run a watcher node. At least in my mind right now, this sounds like an amazing idea.
I’ll sleep over it
