TLDR
- Buterin said Ethereum will focus on security, decentralization, and user control.
- The roadmap targets single-slot finality in about 10 to 20 seconds.
- ZK-EVM is expected to become a main validation method by around 2028.
- Ethereum plans account abstraction, privacy support, and higher execution capacity.
- Long-term goals include quantum resistance and simpler protocol design.
Ethereum’s next five years may be shaped by faster finality, ZK-EVM, and quantum resistance. That was the message from Ethereum co-founder Vitalik Buterin at the 2026 Hong Kong Web3 Carnival. He presented Ethereum as a secure settlement network, not a chain built for maximum speed.
Buterin said Ethereum has two main roles. One role is to publish messages in a public and verifiable order. The other is to run shared digital objects through code, while protecting user control, security, and fair access.
Short-term roadmap centers on scaling and user tools
Buterin said Ethereum’s short-term protocol goals include scaling, ZK-EVM progress, privacy, and stronger block construction. He also named early post-quantum readiness as a near-term priority. The plan aims to improve capacity while keeping the base layer trusted.
He said the next hard fork may include several Ethereum Improvement Proposals. These include parallelized block-level access lists, gas repricing, and better node state sync. The roadmap also allows longer block validation through ePBS.

Another focus is account abstraction through EIP-8141. Buterin said this would treat transactions as a series of calls. It would support smart contract wallets, gas payment flexibility, privacy tools, and quantum-resistant signatures.
He also pointed to faster finality as a near-term target. The goal is single-slot finality in about 10 to 20 seconds. That could help users get quicker confirmation and support lighter verification on smaller devices.
Mid-term plans target state growth and lighter verification
The mid-term phase focuses on Ethereum’s state layer. Buterin said scaling the execution layer is easier than scaling state. So the roadmap turns to state tree optimization and better storage design.
One goal is to limit long-term state growth. Another is to explore systems that do not require all states to stay stored forever. That could reduce storage pressure on nodes and support easier network maintenance.
Buterin also linked these changes to verifiability and self-sovereignty. He said users should be able to verify the chain more easily. This approach could help more users check on-chain data without heavy hardware needs.
ZK-EVM also sits within this broader path. According to the roadmap, by 2025 it should be “fast enough” for real-time EVM proving. The 2026 goal is to make it “secure enough” for limited use by some nodes, including independent stakers.
Long-term goals focus on security hardening and protocol durability
The long-term roadmap has five protocol goals. These are maximum secure consensus, formal verification, full quantum resistance, maximum simplicity, and “foresight.” Buterin described foresight as a walkaway test for protocol safety.
He said Ethereum wants consensus that can withstand 49% node failures in synchronous networks. He also said finality security should hold at 33% in asynchronous networks. These targets aim to strengthen protocol safety over time.
Quantum resistance was presented as a major security goal. Buterin said post-quantum signature schemes have existed for about 20 years, but efficiency remains the main issue. He said signatures can reach 2 to 3 KB, while on-chain use may cost about 200,000 gas.
He named hash-based signatures and “lattice + vectorization” schemes as possible paths. The roadmap also says ZK-EVM could become Ethereum’s main validation method by around 2028. Together, these steps place Ethereum’s future around security, privacy, and durable base-layer design.
