- Ethereum’s PSE sets a three-track plan to make default privacy standard across the stack.
- Initial targets include PlasmaFold transfers, a private voting report, and RPC privacy work within six months.
The Ethereum Foundation has published a roadmap that places default privacy at the center of network development and has renamed its research unit to Privacy Stewards of Ethereum. The document sets out a phased plan to embed privacy by design across protocol, infrastructure, networking, applications, and wallets.
PSE outlines three tracks for private writes, private reads, and private proving
The plan groups work into three focus tracks. “Private writes” aims to make confidential on-chain actions as seamless and affordable as public ones. “Private reads” targets the ability to query state and interact with applications without exposing identity or intent.
“Private proving” focuses on efficient generation and verification of zero-knowledge proofs to enable portable, data-minimised attestations across on- and off-chain contexts.
Over the next three to six months, PSE lists concrete deliverables. These include advancing PlasmaFold as a layer-2 pathway for private transfers and supporting the Kohaku privacy wallet.
The team also plans a “State of Private Voting 2025” report and workstreams to inform privacy specifications for decentralised finance through an Institutional Privacy Task Force.
PlasmaFold, private voting report, and RPC privacy working group scheduled
On the networking side, PSE will convene a Private RPC working group and explore approaches such as oblivious RAM and mixnet-based transaction routing using the Sphinx construction. The objective is to reduce metadata leakage from wallet to endpoint and to improve broadcast privacy for transactions.
Identity and data-portability initiatives feature prominently. PSE intends to harden zkTLS through the TLSNotary stack and ship a developer SDK to ease integration across mobile, server, and browser environments.
this is huge. seeing this level of focus on privacy is a massive signal and makes me hopeful that we will actually be able to use privacy primitives on L1 cheaply to build a new generation of private apps on ethereum

The team will also pursue standards for generic zk-SNARKs, design unlinkable verifiable presentations aligned with European identity frameworks, and study scalable credential revocation. Client-side proving remains a priority through efforts such as Mopro, PPD, and Noir acceleration in collaboration with ecosystem partners.
The roadmap frames privacy as necessary to Ethereum’s role in digital commerce and governance. PSE says it will coordinate with protocol teams where base-layer changes are needed and with application builders to make privacy usable, cost-effective, and consistent with global compliance requirements.
The rebrand underscores a shift from open-ended cryptography experiments to outcome-oriented stewardship and measurement.
At the time of press Ethereum (ETH) is trading at US$4,531.05, down –2.33% over the past 24 hours.
