Vision for Ethereum Advocates Million Transactions Per Second (TPS), Zero-Knowledge Virtual Machines (zkVMs), and Post-Quantum Security

In a groundbreaking move, the Ethereum Foundation unveiled Lean Ethereum, a long-term development framework aimed at revolutionising the world's largest blockchain. This ambitious project, announced in mid-2025 by Ethereum Foundation researcher Justin Drake, is now a central part of Ethereum's 10-year roadmap.

The goal of Lean Ethereum is to future-proof Ethereum by enhancing its scalability to an unprecedented 1 million transactions per second (TPS) on layer 2, while also implementing post-quantum resistant security measures. Key features include:

1. Improved Scalability: Lean Ethereum aims to achieve 10,000 TPS on Layer 1 and up to 1 million TPS on Layer 2 through advanced scalability solutions like zkVMs (zero-knowledge virtual machines) and Data Availability Sampling. This will speed up verification without overloading nodes.
2. Post-Quantum Security: To address emerging quantum threats to blockchain security, Lean Ethereum will transition to quantum-resistant cryptographic algorithms and account verification methods. This includes the implementation of hash-based signatures and lattice crypto.
3. Lean Consensus Mechanism: A streamlined transaction validation and data handling mechanism is intended to increase speed and reduce network complexity.
4. Protocol Simplification: The base layer will be simplified to enhance maintainability, robustness, and security, prioritising a minimalist design while preparing the network for future technological challenges.

As of August 2025, development progress is in its early stages. Migrating existing infrastructure, ensuring backward compatibility, and conducting extensive security audits are significant tasks ahead. The Ethereum community and developers are expected to collaborate to ensure smooth transitions for users and decentralized applications (dApps).

Lean Ethereum embraces the principles of open research, modular upgrades, and community-review. Cysic_xyz, who reported FPGA-based modified machines to be 10 times faster than a CPU in 2024, is spearheading the hardware development of zkVMs for Lean Ethereum. Real-time zk proof generation is supported by Cysic_xyz's hardware in zkVMs.

The vision of Lean Ethereum positions Ethereum as a long-term digital infrastructure that bridges the gap between innovation and foundational needs. It is compatible with scalable DeFi, DAOs, and NFT, allowing developers to create dApps that support real-world external user demands.

Lean Ethereum's improved architecture targets billions of applications worldwide, with a target of 1 million transactions per second (TPS). Developed on July 30, 2025, it indicates a movement towards lightweight protocols and modular design.

In summary, Lean Ethereum is a visionary upgrade that aims to future-proof Ethereum by simultaneously enhancing throughput to levels far beyond current blockchains and integrating robust defenses against quantum computing risks, leveraging zkVMs as a core technology component.
