WHO WE ARE

PSE is a team part of the Ethereum Foundation.
Our goal is to keep expanding the use cases for Ethereum by exploring, building and experimenting with new cryptographic primitives. We explore all areas around “programmable cryptography” (ProgCrypto) but have a current particular focus on zero-knowledge.
We build open source tooling, research, protocols, libraries, DSLs, POCs, reference applications, etc.
Everything that we do is open source public good, and we want to find ways for the ecosystem to adopt it!

Sometimes we focus on more experimental and “long shots” sometimes we work on problem spaces as other teams do too.
One of the things we enjoy the most is finding teams that could adopt our work and findings, provide feedback and in general collaborate technically on keep pushing the space forward.
We’ll never become a for profit and we’ll never want to compete with “commercial teams” but rather partner with organizations with the same ethos.
