Hyperledger Umbra - Scaling Experiments

About the Organization

For the past two years, the Hyperledger Umbra lab has been worked on by mentees to develop the capability of running the unmodified Hyperledger Fabric docker images under a simulated network environment for the purposes of doing experiments on running Fabric networks in a controlled way. At the end of last summer, Hyperledger Umbra achieved the initial goal of running Fabric networks under simulation. Hyperledger Umbra is useful for doing network-level security fuzzing as well as network scaling experiments and this mentorship is focused on designing and executing scaling experiments. Hyperledger Fabric networks are designed to scale up fairly easily, however nobody has actually tried scaling Hyperledger Fabric to many hundreds and thousands of nodes and done analysis on how it affects the characteristics of the distributed system such as time to reach consensus, time to run an election for block creation, etc. The mentee chosen for this project will work with their mentor to design a plan for setting up, executing, gathering and analyzing data, and reporting the results of scaling experiments run at different scales.
