What prompted the overhaul of the old Ethereum roadmap
Why Ethereum’s economics are changing and what exactly AI will control

Ethereum co-founder Vitalik Buterin has presented a major update to the network’s technological direction, radically changing its development priorities. The “Strawmap” he published eliminates the old six-phase roadmap — including the Merge, the Surge and others — and divides the blockchain’s evolution into three architectural layers: consensus (CL), data (DL) and execution (EL).

The main marker of the new strategy is Ethereum’s official shift toward protection against future quantum computers, comprehensive user privacy and the integration of AI tools for code verification, while abandoning several older technological ideas.

“Ethereum will be quantum-safe. Ethereum will put users’ privacy first. Ethereum will be secure. Ethereum will be censorship-resistant. Ethereum will be highly performant and scalable while satisfying the above. And Ethereum will be Lean.” — Vitalik Buterin

What prompted the overhaul of the old Ethereum roadmap

Expectations that powerful quantum computers could emerge soon have forced researchers to rewrite the security roadmap with the introduction of a post-quantum public-key registry and PQ transactions.

Buterin emphasized that the roadmap now includes “aggressive scaling in the context of post-quantum,” involving lightweight LeanSPHINCS signatures and “zkzk” cryptographic frameworks.

To achieve this, developers have made difficult trade-offs: Verkle trees, which had been under development for years, have officially been declared obsolete. According to Buterin, some elements were “replaced with superior constructions.”

In this case, Verkle trees gave way to Poseidon binary trees (PBTs), originally designed to work efficiently with the complex mathematics of STARK proofs.

Why Ethereum’s economics are changing and what exactly AI will control

Instead of attempting to “maximally scale ALL Ethereum activity,” developers are creating specialized mechanisms that have more restrictive properties. They are intended to support “the heaviest loads incurred by users and applications today and tomorrow,” including token transfers, fast swaps and privacy protocols.

The technical foundation of this approach will consist of recursive STARK proofs and native rollups, which could not even have been considered in 2023 because “SNARKs were nowhere near mature enough.”
