  • When people asking Hyperledger deployment method or questions from outside of the community,response emails often point people to the cello project readme docs and rocket channel.
  • Cello currently has 4 maintainers who are actively working on the project and contributing.
  • Cello maintainers also take turns updating the cello wiki pages and required document like this, they also attend meetup positively and share use case to improve Cello's influence among the Hyperledger community.
  • The intern Wang Shuo help to integrate the Fabric Ca into cello, the purpose is get rid of the crypto-gen tool, and more important is enable user to expend their Fabric cluster flexibly.
  • The community is working hard on user dashboard and Kubernetes agent, the target is enable user to deploy chaincode easily to Fabric cluster hosted on Kubernete cluster easily.

Current Plans

  • Add test cases to Kubernetes agent.
  • Improve user experience of Kubernetes agent.
  • Supporting Fabric v1.2 in User dashboard.
  • Support dynamic certificate generation&management.
  • Support import existed fabric network into cello pool.
  • Integrate blockchain-composer.

Maintainer Diversity

There are 4 maintainers from IBM (2) and Oracle (1) and VMware(1), covering both North America and Asia Pacific. We nominate new maintainers based on continuous contributions in terms of code, QA/education, doc and review activities.

Contributor Diversity

Current number of project contributors are 46 with 45 patch sets merged and 5 new code contributors get involved in this project since June, with more and more feedback and attentions from the community, this number will certainly increase.

Additional Information
