Catenaa, Monday, September 15, 2025- The Ethereum Foundation has unveiled a roadmap aimed at building full end-to-end privacy into the blockchain, outlining steps to make private onchain actions seamless, affordable, and compliant.
The foundation’s Privacy & Scaling Explorations team rebranded as the Privacy Stewards of Ethereum and released the plan Friday.
The roadmap focuses on three areas: private writes, enabling confidential transactions as smooth as public ones; private reads, allowing blockchain access without exposing user identity; and private proving, making zero-knowledge proof generation faster and more accessible.
Sam Richards, who compiled the roadmap, warned that without strong privacy safeguards, Ethereum risks becoming a tool for surveillance instead of freedom.
The roadmap stresses that privacy is necessary for Ethereum to achieve its role as a global settlement layer.
The foundation said it will continue developing PlasmaFold, an experimental Layer 2 design with privacy transfer features, with hopes to debut a proof of concept at the Devconnect conference in Argentina in November.
It also plans to issue a report on private voting this year and is working on confidential DeFi projects designed to balance privacy and regulatory needs.
To support private reads, Ethereum developers are testing privacy-preserving RPC services, while the “prove anywhere” initiative seeks to simplify zero-knowledge proof generation on consumer devices.
The roadmap was shaped with input from Ethereum co-founder Vitalik Buterin and other researchers.
