Matter Labs, the innovative developer firm behind the layer-2 network ZKsync, has made a significant announcement at the Permissionless conference: the unveiling of their new cryptographic prover, “Airbender.” This cutting-edge technology is designed to generate zero-knowledge proofs, which play a vital role in linking layer-2 solutions with the Ethereum mainnet, ensuring the security and integrity of transactions.
Airbender positions itself as a formidable contender in the market, boasting the ability to deliver Ethereum block proofs in an impressive 35 seconds using just a single GPU. This remarkable speed surpasses existing benchmarks set by competitors, which could lead to reduced transaction costs. “We’re entering fraction of a cent territory which is critical for key use cases, including micropayments, high-frequency trading, and decentralized social,” noted Alex Gluchowski, co-founder of Matter Labs, underscoring the impact of Airbender on a variety of applications.
“Faster proofs unlock faster finality, cheaper apps, and crucially, proofs that can be generated anywhere, not just in massive GPU farms,” Gluchowski added in an interview with CoinDesk.
This new prover is an open-sourced zero-knowledge virtual machine (zkVM) based on the RISC-V programming framework, a concept that has gained traction among Ethereum advocates, including co-founder Vitalik Buterin. The adoption of RISC-V aims to enhance the efficiency of the Ethereum blockchain and facilitate the evolution of zero-knowledge applications.
Having spent over a year in development, the ZKsync Airbender reflects a proactive approach to meet the future demands of Ethereum and its ZK apps. As Gluchowski shared, “Vitalik’s recent post was a great affirmation of our plans, but this path has been in motion for a while.” Currently, Airbender is in an early rollout phase, with an app available for developers to test its capabilities. Subject to approval through the ZKsync governance process, Airbender is set to be integrated into a protocol upgrade scheduled for later this summer.
“ZKsync Airbender proves Ethereum blocks in 35 seconds using a single GPU. That’s the start of something groundbreaking: home-proving, real-time cross-chain UX, and ZK apps that can verify on the fly. This is the foundation for an Internet of verifiable, interconnected chains,” Gluchowski stated.

Matter Labs Unveils Airbender: A Game Changer for Ethereum’s Layer-2 Solutions
The introduction of “Airbender” by Matter Labs marks a pivotal moment in the realm of layer-2 networks, particularly for Ethereum. This innovative cryptographic prover promises to revolutionize how zero-knowledge proofs are generated and implemented. With lightning-fast performance, Airbender boasts the ability to deliver Ethereum block proofs in just 35 seconds using a single GPU, setting a new benchmark in the industry. This speed not only enhances transaction efficiency but also significantly reduces costs, opening the floodgates for various applications like micropayments and high-frequency trading.
When compared to existing solutions in the space, Airbender presents distinct competitive advantages. Its unique focus on affordability and accessibility stands in stark contrast to other layer-2 networks that rely on extensive GPU farms for processing, potentially alienating smaller developers or projects with limited resources. By democratizing the proof generation process, Matter Labs could attract a broader range of developers and projects aiming for efficiency without incurring hefty expenses.
However, the launch comes with challenges. While the Airbender is poised to make great strides, its performance hinges on successful integration and approval through the ZKsync governance process, a step that presents potential delays and uncertainties. Moreover, the reliance on RISC-V as a programming framework, although endorsed by Ethereum co-founder Vitalik Buterin, may pose a learning curve for developers accustomed to the traditional Ethereum Virtual Machine (EVM) environment.
This innovation in zero-knowledge proof technology could benefit projects focused on cost-effective and speedy transactions, like decentralized exchanges and microservices. On the flip side, slower or less adaptable platforms may find their user bases dwindling as developers migrate towards solutions that prioritize efficiency. The advent of Airbender could indeed create ripples across the Ethereum ecosystem, solidifying its relevance in the face of rising competition in the layer-2 space.
