## AI overview

The article presents "lean Ethereum" as a vision for Ethereum's next decade, focused on combining higher performance with security and decentralization. It proposes upgrades to consensus, data availability, and execution, including post-quantum cryptography, real-time zkVMs, data availability sampling, and a possible SNARK-friendly RISC-V-based instruction set.

## Source excerpt

Yesterday Ethereum turned 10. Today, lean Ethereum is unveiled as a vision--and personal mission--for the next 10 years. We stand at the dawn of a new era. Millions of TPS. Quantum adversaries. How does Ethereum marry extreme performance with uncompromising security and decentralization? TLDR: next-generation cryptography is central...
