Aleph Zero Launches First EVM-Compatible ZK-Privacy Layer with Subsecond Proving Times

·

The blockchain landscape is undergoing a pivotal transformation as privacy and scalability converge in innovative ways. At the forefront of this evolution is Aleph Zero, which has unveiled a groundbreaking advancement: the world’s first EVM-compatible ZK-privacy layer capable of generating zero-knowledge proofs in under one second on consumer-grade devices. This milestone ushers in a new era for private, high-performance decentralized applications across Ethereum and beyond.

A Leap Forward in On-Chain Privacy

On June 20, 2024, the Aleph Zero Foundation announced the launch of its ZK-privacy EVM Layer 2 solution, built on Arbitrum Orbit and powered by Gelato RaaS (Rollup-as-a-Service). This testnet release represents a major leap forward in making privacy both fast and accessible.

Unlike traditional privacy solutions that suffer from long proof generation times and high computational costs, Aleph Zero’s new layer achieves subsecond proving times—as low as 600–800 milliseconds—on standard hardware using common browsers like Chrome and Safari. This eliminates friction for end users and developers alike, enabling real-time private transactions without sacrificing security or decentralization.

Introducing zkOS: Privacy-as-a-Service for Web3

Beyond the Layer 2 upgrade, Aleph Zero has introduced zkOS, a client-side, chain-agnostic zero-knowledge operating system designed to bring seamless privacy integration to any application. Think of it as Privacy-as-a-Service (PaaS) for Web3, supporting both WASM and EVM-compatible networks.

zkOS empowers developers to embed privacy features directly into dApps with minimal overhead. Whether it's a DeFi protocol needing confidential transactions or an enterprise application handling sensitive data, zkOS offers a modular, scalable framework. It leverages Halo2 with KZG commitments for efficient proof generation and uses a universally trusted setup to ensure long-term security.

While integrating ZK tech can be complex, Aleph Zero mitigates this with its zkToolkit, which streamlines deployment across existing ecosystems like Ethereum and Aleph Zero’s native WASM environment.

“Privacy is still mostly unsolved; it's costly, complex to use and build, and its use cases lack economic incentives. With zkOS by Aleph Zero and the zk-privacy EVM layer 2, we aim to change that not only in the Aleph Zero ecosystem, but also in the broader Ethereum ecosystem.”
— Antoni Zolciak, Co-founder of Aleph Zero

High Performance Meets Developer Flexibility

Aleph Zero’s EVM Layer 2 is more than just a privacy layer—it's a high-throughput execution environment engineered for speed and scalability. Built in partnership with Gelato, it utilizes Arbitrum Anytrust DAC technology to deliver:

This positions Aleph Zero EVM as one of the fastest EVM chains available today—ideal for applications requiring low latency and high concurrency.

Leveraging Arbitrum Orbit’s modular stack gives developers unparalleled flexibility. They can customize their rollups while benefiting from robust tooling, including oracles, block explorers, multi-sig wallets, and more—all integrated into the Developer Testnet.

“Aleph Zero EVM uses Arbitrum Orbits' advanced web3 scaling stack—with the most performant developer tooling—to create the most advanced privacy-enhancing blockchain infrastructure on the market.”
— Luis Schliesske, Founder of Gelato

Why Subsecond ZK Proving Matters

Zero-knowledge proofs are powerful, but historically slow. Most ZK systems require specialized hardware or extended wait times to generate proofs—barriers that limit mainstream adoption.

By achieving subsecond proving on consumer devices, Aleph Zero removes these obstacles. Users no longer need to wait seconds—or even minutes—for private transactions to process. This opens doors for real-world use cases where speed and discretion are critical:

And because proofs run client-side via zkOS, sensitive data never leaves the user’s device.

Use Cases Driving Adoption

Several high-profile projects are already integrating with Aleph Zero and zkOS, demonstrating the versatility of its privacy layer:

These partnerships highlight how privacy is no longer a niche concern—it's becoming essential across finance, gaming, content creation, and enterprise tech.

Roadmap: Building Toward Multichain Privacy

Aleph Zero’s vision extends far beyond a single chain. Its roadmap outlines a strategic path toward becoming a multichain privacy hub:

Additionally, Aleph Zero’s Substrate-based WASM Layer 1—launched in November 2021—will now serve as the data availability layer for its L2 EVM chain and future L3 appchains, creating a cohesive, scalable architecture.
