Episode 242: Halo 2 with Daira Hopwood and Str4d

In this week’s episode, Anna explores Halo 2 with Daira Hopwood and Str4d, cryptographic engineers at Electric Coin Company. They explored what new ideas Halo introduced and how Halo 2 built on these ideas, adding optimisations such as adding Plonk-ish arithmetization to take what was a breakthrough to a production ready proving system.
