Groups and Systems

PegaSys (Protocol Engineering Groups and Systems) is a 50-person team dedicated to enterprise grade blockchain at ConsenSys.

By building Enterprise Ethereum, we can bring together the strengths of public and private blockchains: a large developer community while meeting enterprise needs for privacy and permissioning.

We are focused on privacy, permissioning, scalability, and other features to make Ethereum production-ready.
