Ethereum’s technical roadmap from 2025 to 2030 — articulated primarily by co-founder Vitalik Buterin in a series of essays and conference presentations — describes one of the most ambitious multi-year protocol upgrade programmes ever undertaken in distributed-computing infrastructure. The plan, structured into five overlapping phases known informally as the Surge, the Scourge, the Verge, the Purge, and the Splurge, aims to push the network’s transaction throughput, censorship resistance, and long-term sustainability to levels capable of supporting global-scale applications.

Background — From The Merge to the Roadmap
Ethereum completed its switch from proof-of-work to proof-of-stake on 15 September 2022 in an upgrade known as The Merge. According to figures published by the Ethereum Foundation, the change reduced the network’s energy consumption by an estimated 99.95%. With the energy question settled, Buterin’s subsequent writing turned to scaling: how to expand Ethereum’s transaction capacity by orders of magnitude without sacrificing decentralisation.
The five-phase roadmap was first sketched publicly in a 2021 conference presentation, refined in a 2022 essay, and updated in subsequent posts on vitalik.eth.limo. It is widely regarded as the canonical guide to Ethereum’s development priorities through 2030.
The Surge — Scaling Through Rollups and Data Availability
The Surge focuses on increasing transaction throughput by relying on Layer-2 rollups — specialised chains that execute transactions and post compressed data back to Ethereum mainnet. The headline target articulated by Buterin is approximately 100,000 transactions per second across the broader Ethereum ecosystem.
The 2024 Dencun upgrade, which introduced “blobs” via EIP-4844 (proto-danksharding), is widely considered the first major Surge-phase milestone. The upgrade reduced rollup transaction costs by an estimated 90% on average, according to data cited by L2BEAT and other industry monitoring sites.
Future Surge work focuses on full danksharding — increasing the data-availability bandwidth that rollups can consume — alongside research into data-availability sampling techniques that allow lightweight nodes to verify blob data without downloading it in full.
The Scourge — MEV Resistance and Validator Centralisation
“MEV” — maximal extractable value — refers to value that block producers can capture by reordering or censoring transactions. Left unchecked, MEV creates structural pressure toward validator centralisation, which threatens the network’s censorship resistance.
The Scourge phase addresses this through proposals such as proposer-builder separation (PBS) and execution tickets, which separate the role of choosing transactions from the role of finalising blocks. The goal is to ensure that no single class of participants can extract disproportionate value or impose censorship at the protocol level.
The Verge — Stateless Clients and Verkle Trees
The Verge focuses on enabling stateless validation — a long-term goal that would allow Ethereum nodes to verify blocks without storing the entire network state. The technical foundation is a transition from Ethereum’s current Merkle Patricia Trie data structure to a more compact Verkle Tree structure, which produces much smaller cryptographic proofs.
The expected outcome is that running a full validating node could become feasible on a consumer-grade device — including laptops and even smartphones — rather than requiring server-grade hardware. This is foundational to Ethereum’s long-term decentralisation.
The Purge — Reducing Historical Data Burden
The Purge phase aims to reduce the technical-debt burden of historical state data. Several proposals — including EIP-4444, which would limit the historical-block data that nodes are required to retain — would simplify node operation and reduce long-term storage requirements.
The phase also includes ongoing work to retire deprecated opcodes and clean up legacy edge cases in the protocol specification.
The Splurge — Account Abstraction and Improvements
The Splurge collects various smaller-scope improvements that did not fit neatly into the other four phases. The most-discussed component is account abstraction — most prominently advanced through EIP-7702, a proposal that would allow Ethereum’s existing externally-owned accounts to behave like smart-contract accounts, with features such as gasless transactions, batched operations, and account recovery.
Other Splurge work includes ongoing improvements to the Ethereum Virtual Machine (EVM), upgrades to cryptographic primitives, and quality-of-life changes for developers.
Estimated Timing and Open Questions
Specific timing of upgrades on the Ethereum roadmap is not committed in advance — protocol changes pass through community proposal, testing, and governance stages before activation. Public statements from Buterin and from the Ethereum Foundation suggest that full danksharding and the Verkle transition are likely multi-year efforts, with completion projected toward the latter half of the decade.
Open questions raised by analysts at Ledger Insights and other industry research groups include how the Layer-2 ecosystem will fragment liquidity, whether rollup-centric scaling will preserve composability, and how account abstraction will reshape the experience of using the network.
What This Means for the Next Five Years
Taken together, the roadmap describes a network that, by 2030, is meant to be: significantly more scalable (via rollups and data availability), more censorship-resistant (via PBS and MEV mitigation), more accessible (via stateless clients), simpler to maintain (via the Purge), and more user-friendly (via account abstraction).
The success of the roadmap will ultimately depend on coordination among hundreds of independent teams — protocol researchers, client implementers, rollup operators, application developers, and the Ethereum Foundation itself. Past upgrades, including The Merge and Dencun, have been delivered roughly on schedule with no major incidents, providing some basis for confidence in the network’s ability to execute on the remaining phases.
