Hyperledger Project Update


Hyperledger Cello

Project Health

Cello community is very active.

  • Channel #cello on is the main communication method.
  • New ideas are proposed and discussed constantly on the channel.
  • Weekly call on every Friday 12:30 PM UTC was setup, first regular meeting was held on March 9, 2018
  • Majority of the patch sets gets reviewed and commented within 24 hours


No urgent issues, but it would be helpful to provide some machines to create fabric test net, to help people to experience fabric/cello platform's latest feature quickly.


Release history:

  1. v0.6.0: 2017-06-24
  2. v0.7.0: 2017-10-20
  3. v0.8.0: 2018-03-31 (planed)

Overall Activity in the Past Quarter

  • Conversation mostly happen on the rocketchat channel, emails were answered as well.
  • 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.
  • The community is working hard to provide a solution so that people can adopt and experience hyperledger techniques easily, we already integrated the blockchain-explorer project, and now are actively integrating fabric composer into the project. Once this feature is complete, users will be able to stand up fabric network and start developing their business network using composer.
  • Cello currently has 3 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.

Current Plans

  • Ensure the release of 0.8.0
  • Integrate fabric composer to the created fabric network
  • Create more mini-series of how-to videos
  • Update documents so that users can get started quickly

Maintainer Diversity

There are 3 maintainers from IBM (2) and Oracle (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 is 25 with 62 patch sets merged since last December. With project gets more attention, this number will certainly increase.

Additional Information

Cello developers have been participating in local meetups and global hackfest events to promote and demo the project, and help attract more people to join and use hyperledger products.
