The way I like to see halo is you do most of the verifier's work. You get down to polynomials and rather than checking your polynomial commitments, you defer that to later. What you're folding is claims about polynomial. So if you look at the circuit for executing a batch, it consists of a sequence of subcircuits where each of those subcircuits are the same.
In today’s episode, Anna Rose and Nico Mohnblatt interview Srinath Setty, Principal Researcher at Microsoft Research and author of notable works such as Spartan, Nova, SuperNova, and HyperNova. This discussion covers Setty's early work and how this led to him working on SNARKs, folding schemes and sumcheck protocols, as well as his views on the future trajectory of the ZK space.
Given the current chatter around Nova-style accumulation schemes, this interview offers a chance to explore the perspective of a key contributor behind these developments.

Zero-knowledge is changing the world and until now, building ZK applications meant learning new, chain-specific languages and complex cryptography. But no more!
With SnarkyJS, the easiest to use zk SDK, developers can add the magic of zk to their apps using TypeScript!
Whether you're targeting Mina, the leading zk-native blockchain, or off-chain applications, SnarkyJS from O(1) Labs has you covered. With support for infinite recursion, in-browser proving, and so much more, the full power of zk is available to everyone.
