Website: https://vitalik.ca/ Talk description "What makes an ideal state tree?" The Ethereum research community has recently been focusing on changing the state tree structure to enable stateless clients, with a lot of focus on Verkle trees as a solution. But what are the requirements for a state tree, and why won’t other alternatives (eg. polynomial commitments, accumulators) also work well? I describe the often quite subtle requirements that a tree structure suitable for state trees in Ethereum needs to fulfill, and while Verkle trees, while imperfect, are better than anything else we have seen so far.
