Vitalik Buterin Details Ethereum Scaling Roadmap with Glamsterdam Gas Changes, Multidimensional Pricing and Phased ZKEVM Rollout

Vitalik Buterin said on X that Ethereum's scaling roadmap splits into short-term and long-term tracks, with near-term upgrades including Glamsterdam adding block-level access lists for parallel verification, ePBS increasing the share of slots used for block verification, and gas repricing plus a phased multidimensional gas mechanism to better align costs with execution time, Odaily Planet Daily reports. Under Glamsterdam's first phase, "state creation" gas will be priced separately from "execution and calldata" and excluded from the roughly 16 million transaction gas limit, while an EVM-level "reservoir" dimension will default to consuming dedicated dimension gas before drawing from the reservoir, later moving to multidimensional pricing where different dimensions have distinct floating gas prices. For long-term scaling, Buterin highlighted blobs and ZKEVM, with blob capacity targeted via continuous PeerDAS iterations toward about 8 MB per second so Ethereum block data can be stored directly in blobs, and a staged ZKEVM adoption where ZKEVM-capable validator clients are planned by 2026 for around 5% of the network, expanding to more nodes by 2027 as formal verification progresses and eventually shifting to a mandatory 3-of-5 proof mechanism and ongoing security and VM work including RISC-V.
