Privacy Stewards of Ethereum

PSE is a research and development lab delivering privacy to the Ethereum ecosystem.

Our MissionEthereum is the foundation of a freer digital world, but it will not reach its full potential without privacy. We're building cryptographic tools, co-creating standards, and coordinating throughout the ecosystem to make privacy practical for Ethereum.

What we do

Building open source tools

We develop open source tools for things like data provenance, private identity, voting, and more to make privacy a core feature of Ethereum's application layer.

Researching new applications

We benchmark primitives, systematize knowledge, and explore new ideas with the potential to transform the capabilities and impact of programmable cryptography.
