Episode notes
The traditional way to do this most naively would literally be to like represent the matrix multiply operation as a circuit. When you apply a snark to that circuit, the prover is proving not just that it knows the product, but that it computed in a specific way. So with these special purpose snarks I'm referring to, you don't even have to have the prover cryptographically commit to these product matrices. That could blow away this whole goal of having kind of a low order runtime overhead for the prover to compute the proof. This all falls under the category that people might be starting to hear about, just like CKML.
