Our bi-weekly meeting we’ll discuss architecture requirements for mobile blockchain apps and distributed use cases.

  • On requirements we plan a working group document spanning from IoT to AI – Aaro

n will drive this.

  • On solutions we plan ReqWG document specifying the permissions from IoT to AI - Clive will drive this.
  • We plan these papers as yin and yang to tell what is possible in blockchain and how to implement with Hyperledger projects. With peer review feedback via ReqWG.
  • In a grander vision we envision working for resources to outline open source implementation of a mobile client app for blockchain transactions. Toward Brian Behlendorf’s vision on Hyperledger's open-source standardization efforts at Mobile World Congress. https://youtu.be/K6Da9zJYgYY

October 16th, 2017

GE Digital is interested in spurring a discussion on Hyperledger blockchain for Financial Master Data Management in ERP at today’s bi-weekly. If you are interested in ERP at global scale this could be an exciting discussion. Please see our Antitrust Policy

Based on discussion a solid blockchain use case emerged for managing financial metadata between customers and suppliers and ERP. Recommended reading is Ian Grigg's triple entry accounting. Projected productivity benefits are automatic payments automatically managing days outstanding.

Second use case is around counterfeiting. As discussed this was more product and supply chain based than ERP financial metadata.

Attendees

  • Clive Boulton. Independent Lead, Hyperledger
  • Neviana Zhgaba. Finance Master Data Management at GE Digital
  • Aaron Bennington, TCS

October 2nd, 2017

Today's ReqWG discussed 'See Through Coffee' and traceability in co-op supply chains with a goal to building an open coffee supply chain traceability app for co-op growers. Into solving Inventory bullwhip and the UI app interoperability possibilities with chaincode.

We also discussed blockchain for Financial Master Data Management in large scale ERP. GE Digital is interested in a discussing Hyperledger blockchain for Financial Master Data Management in ERP at the next bi-weekly. If you grok SAP or Oracle internal ERP architecture this could be an exciting discussion.

Likewise if you know how to implement smart contracts beyond Fabric Composer, we need community architect input.

September 17th, 2017

Brian Behlendorf visited our bi-weekly call and challenged us to work together on requirements and sample code to allow applications across different Hyperledger projects. For example Hyperledger Composer for smart contact apps works on Hyperledger Fabric but not on Hyperledger Sawtooth. Today we will discuss your requirements, how we can work together.

To get us started Victor's group has been working on and built a benchmarking project working across different blockchains named Caliper here: https://github.com/Huawei-OSG/caliper

Please take our survey to help us accelerate requirements for Hyperledger apps http://bit.ly/2pKKaKR

* Patrick Holmes announced his resignation

* Oleg Abdrashitov proposed [ideas to improve the development of the Requirements Document](https://docs.google.com/document/d/1BlWWgtGArBb7v_cJsaJ9SsMclRHNfEdaJ623CrDHez8/edit?pref=2&pli=1)

  • Feedback loop: the requirements should feed the Architecture WG and influence their decisions. Produce a monthly report of the new use cases and requirements.
  • Depth: the use cases need to be further developed and conform to the template.
  • Coverage: reach out to industry experts to gather new use cases.

These ideas were supported by the WG and by other key members of the project prior to the meeting.

* Oleg started implementing:

* there's a concern that some project members may be bound by NDAs not to reveal their use cases. One of the solutions is to bring the existing use cases to the experts and have them not volunteer but only validate or comment on them. * a suggestion was made to approach the Linux community for the new use cases

* Christopher Allen walked thru his contribution to the Requirements section of the Use Case template. Proposed to introduce Policy and Regulatory Requirements section * The WG agreed to introduce milestones into the development of the use cases

  • Milestone 1: Sections 1 (Intro and User Stories) and Section 2 (States and Transitions). When completed, announce to the Architecture and other WGs.
  • Milestone 2: Section 3 (Requirements). Work with the Architecture group to develop technical requirements such as Correctness, Privacy, Hardware

* Nikilesh Subramoniapillai Ajeetha shared a mindmap of the requirements space captured so far by WG. It can be accessed [here](https://coggle.it/diagram/VwXUxFREA9UkQydB)

Notes:

  • Christopher Allen - Went over the general requirements, correctness and privacy requirements listed in the Hyperledger project wiki
  • Christopher Allen - Permissioned or Permissionless is a hugely grey area from Requirements perspective. Taking a binary approach may not be the right approach. A permissioned system may need the properties of the permissionless system.
  • Oleg- Hardware requirements- what are the requirements for thin clients? , Privacy Requirements?
  • Christopher Allen - Need more inputs on Hardware requirements( from IOT devices perspective)
  • Nikilesh Subramoniapillai Ajeetha - Shared a mindmap of the blockchain requirements https://coggle.it/diagram/VwXUxFREA9UkQydB
