Vitalik Buterin shared new research that has the potential to reshape the way Ethereum approaches proof verification and scaling in the coming years.
summary
- Vitalik Buterin introduces GKR, a protocol for faster proof aggregation.
- GKR improves the efficiency of Ethereum’s ZK and rollup systems.
- This marks a step towards Ethereum’s “lean” and quantum secure vision for 2025.
Vitalik Buterin introduced the GKR protocol, a breakthrough system designed to make zero-knowledge computations faster and more efficient.
Posted on my blog on October 20th Vitalic S. RimoButerin’s new tutorial details the Goldwasser-Kalai-Rothblum protocol. This recursive proof aggregation method could completely change the way Ethereum (ETH) handles scaling and verification.
The future of the GKR protocol and proof efficiency
The GKR framework validates large-scale computations and simplifies complex cryptographic proofs with little on-chain overhead. Buterin describes how GKR processes proofs in logarithmic time without the need for costly intermediate commitments, making it much more efficient than traditional ZK-SNARK and STARK systems.

In his post, Buterin thanked Lev Soukhanov, Zhenfei Zhang, and Zachary Williamson for their feedback and reviews, and emphasized that GKR’s core strength is its scalability. “This is a natural fit for proving large-scale hashes and neural network-style computations,” he wrote, highlighting its suitability for both blockchain and AI workloads.
The design of the protocol allows the prover to omit commitments at intermediate stages, reducing cost and computational load. GKR itself is not zero-knowledge, but can be wrapped in a ZK-SNARK or STARK layer to ensure privacy, combining simplicity and confidentiality.
Key parts of Ethereum’s roadmap
GKR aligns with Buterin’s broader vision for “Lean Ethereum,” a simplified quantum-resistant network design. This directly supports Ethereum’s movement toward finality acceleration, rollup proof aggregation, and zero knowledge-based scalability.
This release follows several related initiatives from Buterin, including advanced interoperability tools between layer 2 networks, partially stateless clients that minimize node storage, and governance enabled by ZK. Together, they aim to make Ethereum more efficient, private, and accessible.
Ethereum’s crypto backbone could become lighter and faster as developers begin experimenting with GKR-based systems, which would help realize Buterin’s long-term goal of scalable and verified computation.
