Action Item Review

  • December Hackfest

    • Looking to hold a Hackfest in New York on Decemeber 5th & 6th, if you have space to host this, please contact Todd (tbenzies@...)

  • wiki.hyperledger.org migration

    • Restricted editing access on the Github wiki -- please put all future updates on wiki.hyperledger.org and continue to migrate your old content over.

  • Communication Tools - evaluating discuss.hyperledger.org (please create your account, if you have not already)

    • More achievable than Slack, not necessarily looking to get rid of Slack

    • Discourse is better for threading and archiving

    • There may be some things we can do to integrate

    • Brian B:  Would love to see if Discourse is an appealing alternative to email.  Could also explore alternatives to Slack (like RocketChat).  But, let’s first get through Discourse evaluation task.

    • CF:  If there are other ideas or other tools -- please let us know!

  • Whitepaper WG update (Dave Voell)

    • A few weeks since whitepaper walkthrough -- seeking guidance from the TSC and technical community on aligning the overall vision/objectives for this paper.

    • With the message that Hyperledger is more towards “umbrella org,” need to incorporate this into the overall direction of paper.

    • Mic:  Want a commitment from the TSC on the set of objectives for the whitepaper.

    • DRAFT:  https://wiki.hyperledger.org/groups/whitepaper/whitepaper-wg

    • Brian B:  Where do you prefer comments?

      • Mic:  First we need to establish objectives, as opposed to comments on the doc.

      • Muali:  suggest to add this as a topic at the members meeting, too.

    • TSC thread has started on this topic

    • Encourage all to attend the next meeting:

HIP:  Iroha (Makoto Takemiya)

  • Proposal

  • Source

  • Mic:  What are the objectives for modularity?

  • MT:  Current draft is very rough… we want to make each piece less dependent on each other.

  • Mic:  To what extent has current code base been tested and how to describe maturity?

  • MT:  Current is still very rough -- has been tested with some use case partners in Japan.  But, this is an advantage to bring into incubation stage at this point.

  • Hart:  Like vision of modular components.  At what point do you expect to achieve modularity?  Early on or do you want to have a complete ledger and then focus on modularity.

  • MT:  Want feature-complete version first.  At API level already looking at ways to bring things together.  Create cross-chain transactions between Iroha and Fabric (can do with STL, as well).

  • VOTE:  Unanimously approved.

Java Chaincode demo (Satheesh Kathamuthu, DTCC)

  • Satheesh Kathamuthu provided a demo of Java Chaincode

  • Recording
