Vitalik Buterin Releases GKR Tutorial
Ethereum co-founder Vitalik Buterin has published a tutorial explaining the GKR protocol, a system known for improving zero-knowledge proving performance. The post, shared on October 19, 2025, introduces readers to the cryptographic method that powers modern ultra-fast ZK-provers.
The tutorial explains that GKR enables efficient computation verification by allowing the prover to commit only to inputs and outputs. GKR’s efficiency comes from only requiring the prover to commit to inputs and outputs. The approach helps reduce computational overhead while improving the proving process used in blockchain and machine learning systems.
Understanding GKR and Its Role in Zero-Knowledge Systems
Buterin describes GKR as a protocol family that enhances proving systems such as zkEVM and zkML. These systems enable secure proof generation for Ethereum Layer 1 computations and large-scale model inference. The GKR framework allows high-speed proofs even on consumer hardware, supporting millions of operations per second.
Buterin referenced earlier research and acknowledged contributions from several cryptography experts. The tutorial links to additional resources explaining GKR in the context of circuit evaluation and Poseidon hash proving. It also mentions real-world applications, such as zk-EVM provers processing Ethereum transactions in real-time using consumer GPUs.
By offering this detailed guide, Buterin aims to make the concept more accessible to developers and researchers interested in ZK technology. The goal is to explain how these protocols achieve such high speed and why they matter for future systems.
