2019 Q3 Hyperledger Cello


Project Health

Project health is largely the same as in previous update. The community is making  changes to make Cello more of a production ready tool. Features and capabilities are now more based on common use cases and behaviors of the Blockchain applications. Weekly meetings often see 10+ participates and often run over the allocated 30 minutes due to discussions and questions. In some cases, very well run pass 1 hour mark.


There are no major issues at this time.


  • v0.9.0: Support v1.1/v1.2 fabric in k8s agent, Add v1.3 capabilities to ansible agent.
  • v1.0.0: Most of the changes to the project are towards this release. We like to be very cautious and prudent on this release and will not rush it out.

Overall Activity in the Past Quarter

  • Keep working on the new governing model and relevant APIs.
  • Designed and implemented a new and user friendly dashboard for the new APIs.
  • Updated the document for the new architecture.
  • Bug fixes and documentation improvement.
