Ethereum Foundation Launches Privacy Cluster to Embed Confidentiality Across Network

The Privacy Cluster unites 47 specialists to embed native privacy features across Ethereum’s layer-1 architecture.

The initiative expands on PSE’s 50+ privacy tools, advancing zk-proof interoperability and private identity solutions.

Ethereum’s PlasmaFold layer-2 enables secret transfers while preventing metadata leaks from remote nodes.

The Ethereum Foundation has launched a new Privacy Cluster, a collective of 47 researchers, engineers, and cryptographers focused on developing native privacy infrastructure for the Ethereum network

The initiative aims to make privacy a built-in feature of Ethereum’s layer-1 ecosystem while maintaining alignment with institutional compliance standards. Coordinated by Igor Barinov, the effort focuses on advancing zero-knowledge (zk) technology and cryptographic tools to enhance user confidentiality and data protection across applications and protocols.

Coordinating Privacy Across Ethereum’s Core Layers

The newly formed cluster expands the earlier Privacy and Scaling Explorations (PSE) initiative, which has developed more than 50 open source privacy tools since 2018. According to the Ethereum Foundation, projects such as Semaphore, MACI, zkEmail, TLSNotary, and Anon Aadhaar have set strong precedents in private identity verification and secure voting mechanisms

The Privacy Cluster now brings these technologies under a unified framework. Each of its specialized teams targets different blockchain layers, including Private Reads & Writes, Private Proving, Private Identities, Privacy Experience, and the Institutional Privacy Task Force (IPTF)

Private Reads & Writes will focus on enabling confidential user actions like payments and authentication without leaking metadata. Meanwhile, Private Proving aims to enhance zk-proof interoperability, allowing users to validate ownership or credentials without exposing personal details.

Balancing Institutional Needs and User Protection

The Institutional Privacy Task Force bridges the gap between enterprise compliance and decentralized privacy. It focuses on translating business and regulatory requirements into practical standards for public blockchain use. Its ongoing work includes confidential transactions, compliance ready verification tools, and enterprise workflow protection.

Additionally, Ethereum’s Kohaku project, an open source wallet and SDK, is under development to make advanced cryptographic solutions more accessible for developers. The tool will provide privacy preserving infrastructure for decentralized applications, emphasizing usability and transparent integration

Notably, these initiatives come amid rising global scrutiny over data collection and financial monitoring. Ethereum founder Vitalik Buterin recently urged the community to oppose the European Union’s “Chat Control” proposal, which seeks government access to encrypted messages.

Advancing End to End Privacy Standards

According to blockchain security expert David Holtzman from the Naoris decentralized security protocol, centralized servers remain a primary target for cyberattacks. He noted that decentralized privacy frameworks reduce such risks by distributing sensitive data storage

The Privacy Cluster’s structure builds on this idea, introducing PlasmaFold, a layer-2 solution enabling secret transfers while protecting metadata from remote procedure call (RPC) leaks. The Ethereum Foundation stated that it is collaborating with over 700 privacy focused initiatives to strengthen secure digital infrastructure

Through this coordinated effort, the network seeks to integrate zk-based technologies, institutional frameworks, and user-centric privacy mechanisms to ensure confidentiality at every level of Ethereum’s ecosystem.
