Actions

• Eamonn: Try to get Hyperledger network, Hashgraph & PoC working together

Discussion

General architecture

• We're all enthusiastic about the project
• Summer holidays and work impeding focus and progress
• Eamonn asking whether anyone has run Alex's PoC
  • He is planning to get it working locally this week.
  • He updated readme 10 days ago
  • Eamonn "gradle" renamed "hashgraph sdk spinner"
    • Separate docker containers
    • All nodes can run on same port
  • Network of virtual machines
  • Generates vagrant file
    • spin up number of VMs required
    • reason for VMs was executing VMs in secure enclaves
    • trying to spin up container within a VM
• Should add to readme:
  • Walkthrough: How to use this (code)
  • Benefits: Why to use this
  • Hyperledger project - currently there are 2 mechanisms available:
    • Solo and Kafka
    • Would be good to see Hashgraph added as the 3rd consensus layer
      • If HL users could choose this, big benefits
      • We would hopefully be the obvious winner
• Hedera
  • When available?
  • Viraf: Solidity - performance? Scalability
    • Try known smart-contract and compare performance
  • Persistence issue - exo demo
    • Concern about lack of historical transactions
  • HL Community - should we reach out? Greg: perhaps wait until the plugin PoC is more stable?

Other Points

• Eamonn: Kafka pub/sub?
  • Is it worth engaging with Apache Kafka directly?
  • phased out zookeper
  • if they have re-engineering going on...
    • would it be worth plugging in hashgraph there?
  • private distributed consensus
    • private trusted network
• Viraf: See questions from prior call
  • Issues relating to channels/configs?
• He found BFT Opensource plugin service for hyperledger
  • https://github.com/jcs47/hyperledger-bftsmart
  • Could we replace BFT Smart with Hashgraph
• Tim away next 2 saturdays

Priorities

• Performance Metrics - tps
