What is next on ETH’s roadmap?

TLDR

Ethereum's development continues with these milestones:

  1. Hegota Upgrade (H2 2026) – A major hard fork introducing Verkle Trees for stateless clients and enhanced censorship resistance.

  2. The Strawmap Vision (Through 2029) – A long-term plan prioritizing quantum safety, native privacy, and a leaner, more scalable protocol.

Deep Dive

1. Hegota Upgrade (H2 2026)

Overview: Hegota is the next scheduled major network upgrade, targeted for the second half of 2026. It follows the Glamsterdam upgrade and continues Ethereum's biannual hard fork cycle. A core technical focus is the integration of Verkle Trees, a new data structure that will enable "stateless clients." This allows nodes to verify blocks without storing the entire network state, significantly reducing hardware requirements and improving decentralization. The upgrade is also expected to include Fork-choice Enforced Inclusion Lists (FOCIL) to strengthen censorship resistance.

What this means: This is bullish for Ethereum because it directly tackles long-term scalability and node accessibility, which are foundational for network security and adoption. Reducing storage demands could lower barriers for individuals to run nodes, enhancing decentralization. However, the complexity of implementing Verkle Trees carries execution risk, and any delays could temporarily dampen sentiment.

2. The Strawmap Vision (Through 2029)

Overview: Co-founder Vitalik Buterin updated Ethereum's long-term "Strawmap" in August 2026, outlining a strategic vision through 2029 (CryptoBriefing). The plan elevates quantum-resistant cryptography and native privacy features (like keyed nonces and shielded pools) as top priorities. It also envisions native rollups—scaling layers integrated directly into the base protocol—and a "lean" protocol specification verifiable by AI-assisted formal proofs.

What this means: This is bullish for Ethereum as it proactively addresses existential technological threats (quantum computing) and major user experience gaps (privacy). Successfully embedding these features at the protocol level could solidify Ethereum's position as the most secure and versatile smart contract platform. The long timeline and significant research required mean these benefits are years away, introducing uncertainty and dependency on cryptographic advancements.

Conclusion

Ethereum's roadmap is strategically pivoting from scaling the base layer to future-proofing the protocol with quantum safety and built-in privacy, while steadily improving node efficiency. Will its methodical, research-driven approach allow it to maintain its lead as competing chains move faster?
