PLONK and the universal SRS
How PLONK killed per-circuit ceremonies. We cover the permutation argument, the grand product trick, and why every new zkEVM is PLONKish under the hood.
FROM THE BROADCAST
"Good evening. Tonight we cover plonk and universal setups. This is the kind of topic that sits right on the seam between research and production, and we're going to walk through the construction before looking at what it means for the chains that actually ship it."
"The short version is this: PLONK broke the per-circuit trusted-setup curse. We'll spend the first half of the segment on the core mechanism, and the second half on what operators are actually deploying."
"Let's start with the basics. The structured reference string is universal and updatable, which means a single ceremony serves every circuit whose size fits under the SRS bound. The core trick is a permutation argument over a trace table, turning copy constraints into a single grand-product check. Keep that in mind as we go deeper."
