There's sort of two sources of overhead I call the front and over and in the back and over. The front and overhead is like once you decide you're going to use a circuit, but forget about actually proving anything about the circuit, how much more expensive are things now? So I call that the front and overhead. And then the back end overhead is like how much moreexpensive is it for the prover to prove it knows the satisfying assignment to the circuit compared to just like evaluating the circuit. Both sources of overhead, like are parallelizable away. You can throw tons of GPUs at this. We have special purpose snarks where you never see a circuit in them for this kind of
This week, Anna chats with Justin Thaler, Associate Professor at Georgetown. They cover Justin’s academic history and discuss what led him to working on interactive proofs and SNARKs. They also take a look at several other topics such as the Thaler Book Study Group, his earlier work Spartan, comparing the security of different rollups built with SNARKs and STARKs and more.
