Ethereum’s development roadmap — outlined by Vitalik Buterin using memorable rhyming names — represents the most ambitious blockchain engineering project in the world. After successfully completing “The Merge” (proof-of-stake transition, September 2022), Ethereum’s remaining roadmap consists of five major phases, each addressing critical scaling and security challenges.
The Surge: massive scaling through rollups and data availability improvements. EIP-4844 (completed March 2024) was the first step; full Danksharding will provide orders of magnitude more data availability for rollups. The goal: 100,000+ transactions per second across the rollup ecosystem.
The Scourge: addressing MEV (Maximal Extractable Value) and ensuring fair block production. Proposer-builder separation (PBS), inclusion lists (ensuring censorship resistance), and MEV burn (returning MEV profits to the protocol) aim to make Ethereum’s block production fair and censorship-resistant.
The Verge: making Ethereum verification extremely lightweight through Verkle trees (replacing the current Merkle Patricia tree data structure). The goal: stateless clients that can verify Ethereum blocks without storing the entire state, enabling “everyone runs a node” — the ultimate decentralization dream.
The Purge: reducing the storage burden on nodes by introducing state expiry (old, unused state is archived rather than stored by every node) and history expiry (nodes don’t need to store the entire blockchain history). This makes running a node dramatically cheaper and more accessible.
The Splurge: miscellaneous improvements including account abstraction, EVM improvements, and various quality-of-life upgrades for developers and users.
The roadmap’s ambition is staggering — if completed, Ethereum would be orders of magnitude more scalable, more decentralized, and more censorship-resistant than any blockchain currently in existence. The timeline is measured in years (full completion likely extends past 2030), and each phase involves cutting-edge cryptography and engineering. Whether Ethereum can execute this roadmap while maintaining its role as the leading smart contract platform — fending off faster competitors who don’t carry Ethereum’s technical debt — is the central question for the next decade of blockchain development.
