Privacy Team of Ethereum Foundation Rebrands to PSE, Introduces Comprehensive Onchain Privacy Strategy

The Ethereum Foundation’s Privacy & Scaling Explorations team has rebranded as Privacy Stewards for Ethereum (PSE), introducing an ambitious plan to establish privacy as the standard rather than the exception throughout Ethereum’s technical framework.

This change shifts the emphasis from exploring cryptographic methods to implementing solutions that directly address Ethereum’s vulnerabilities to surveillance.

PSE’s updated mission focuses on three primary areas: private writes to ensure that on-chain activities are as affordable and effortless as public ones, private reads to facilitate blockchain queries without surveillance, and private proving for easy data verification.

This initiative follows Vitalik Buterin’s advocacy in April, highlighting privacy as crucial for Ethereum’s role as a global settlement infrastructure.

The roadmap cautions that without strong privacy measures, Ethereum risks becoming “the backbone of global surveillance rather than global freedom.”

PSE stresses that both institutions and users may seek alternatives if private transactions, identities, and data continue to be at risk due to the transparency of public blockchains.

From Cryptography Lab to Privacy Stewardship Mission

PSE has shifted away from its former strategy of pursuing “cool tech” to concentrate on tangible problem-solving aimed at ecosystem outcomes rather than internal initiatives.

The rebranding includes updates to the website pse.dev and revised team objectives, with a particular focus on subtraction by default and resource allocation driven by problem-solving.

The approach entails ongoing problem mapping, decision-making regarding execution across various engagement levels, and public communication through newsletters, community calls, and working groups.

PSE takes cues from the straightforward announcements of Protocol and EcoDev while incorporating feedback from Vitalik Buterin, the Silviculture Society, and EF management.

Key projects include the development of PlasmaFold for private transfers utilizing PCD and folding, with a proof-of-concept targeted for Devconnect.

The team is also advancing the Kohaku privacy wallet, concentrating on zk account recovery frameworks and keystore implementation for stealth addresses.

Efforts in private governance are directed towards a “State of private voting 2025” report while collaborating with Aragon on protocol integrations.

The Institutional Privacy Task Force is being launched in conjunction with the EF EcoDev Enterprise team to facilitate adoption through privacy specifications and proof-of-concepts.

Another significant aspect of this new direction is PSE’s focus on data portability. It monitors progress in TLSNotary development for production-ready zkTLS protocols while creating SDKs that allow for seamless integration across mobile, server, and browser platforms.

Moreover, network privacy initiatives encompass Private RPC working groups, ORAM solution integration for privacy-preserving state reads, and the implementation of the sphinx mixing protocol for broadcast privacy.

The team has indicated that it will systematically examine ORAM and PIR state-of-the-art techniques while converting research into practical wallet and browser experiences.

Industry Experts Warn Public Ledgers Threaten Mass Adoption

The privacy initiative responds to increasing concerns from industry experts regarding Ethereum’s transparency model.

In an interview with Cryptonews in August, Petro Golovko from the British Gold Trust stated that public blockchains reveal salaries, business transactions, and balance sheets, rendering crypto “unusable for regular people and impossible for institutions.”

Golovko likens the current state of blockchain transparency to the pre-SSL internet, when users hesitated to enter credit card information due to insufficient encryption.

He argues that crypto remains trapped in this precarious phase, hindering the scaling that turned e-commerce into a $6 trillion sector.

Imagine if your bank account had a public URL. That’s the reality of crypto today, and why it “will never scale beyond a niche,” says Petro Golovko.#Crypto #Blockchain #Privacy https://t.co/qQJ1BJInWt

Concerns regarding institutional adoption focus on the risk of exposing trade secrets and the competitive disadvantage that arises from visible treasury movements.

Golovko warns that no board would endorse systems that reveal supply chains or financial operations globally, confining crypto to speculation rather than serious commerce.

Vitalik Buterin’s advocacy for privacy in April arose from similar worries about AI-driven surveillance and data misuse undermining personal autonomy.

His roadmap detailed four areas for improving privacy: anonymous payments, application-level privacy, secure data access, and network obfuscation.

The Ethereum co-founder urged wallets to incorporate tools like Railgun and Privacy Pools, creating “shielded balances” that facilitate private-by-default transactions.

He highlighted that using separate addresses for each dApp would eliminate traceable connections between applications while preserving usability.

Increasing regulatory pressure in Europe amplifies the urgency for privacy development.

Community member Eugenio Reggianini outlined GDPR compliance practices that necessitate personal data to remain off-chain, with blockchain nodes transmitting only encrypted references or proofs, rather than identifiable information.

Looking ahead, the team intends to expedite ecosystem adoption through community initiatives that prioritize privacy and robust security within its decentralized identity systems.
