The Hyperledger Performance and Scale Working Group is not currently active.  If you're interested in the topic of performance and scale with blockchain networks, check out Hyperledger Caliper and the two performance related mentorship projects in our 2023 Mentorship program.


Performance and scalability are two key characteristics of any platform. In terms of most of the  Hyperledger projects, both will directly relate to end user satisfaction and ultimately adoption of a project. For instance, if a code base consumes too many system resources or does not complete an action in a reasonable time with respect to other solutions, it may not succeed. Similarly, if a product does not scale well (horizontally and or vertically), it may not succeed.

The purpose of the Performance and Scalability Working Group (PSWG) is to discuss, research, and identify key metrics that relate to the performance and scalability of a blockchain and blockchain related technologies.


Please see Charter for the full text of the charter.


PSWG serves as a cross project forum for architects and technologists from the Distributed Ledger Technology (DLT) community to exchange ideas and explore the performance and scalability aspects of the DLT projects. PSWG will help review incoming performance project proposals and make recommendations to the TSC. The PSWG may work with the other working groups, especially in the areas of architecture and requirements.
