Ethereum Prepares to Overhaul State Structure with Partitioned Binary Tree
Ethereum is planning to reorganize its state structure with the Partitioned Binary Tree (PBT) upgrade, which aims to enhance scalability and efficiency. The proposal, EIP-8297, passed a mainnet shadowfork test in October 2026. The upgrade will fold three separate categories into a single binary tree structure, simplifying state proofs and reducing the need for state expiry. The mainnet deployment of PBT is scheduled for Q4 2026, with no specific activation date announced.
