Apps Development on Hyperledger Fabric: Advanced Training for Developers [Singapore]

Early Bird tickets available now!

August 26, 2019 @ 9:00 am - August 28, 2019 @ 6:00 pm

This three-day course provides a highly practical training on Hyperledger Fabric with 75% lab exercises and 25% theory lectures. Every student gets personal attention and works with a trainer experienced in developing blockchain applications on Fabric.

By the end of the course, you will design an application and learn how to integrate it with external file storages. You will become proficient in blockchain and fully armed to build real-life applications of any complexity on your own.

Who should attend
  • DevOps engineers setting up and running Hyperledger networks
  • Chaincode developers writing in Golang/Java/Node.js
  • UI/UX developers



Day 1



Architecture of the production-grade Apps

  • Ordering mechanism:
    • Kafka-Orderer: how it works (theory)
    • Multi-host network setup with the Kafka-Orderer (practice)
  • Database choice: LevelDB vs. CouchDB (pros and cons, practical considerations)
  • MSP/CA integration with local credential store:
    • MSP/CA user authentication vs. API-managed user authentication
    • LDAP

Network administration

  • Adding new orgs to a running network
  • Hyperledger Fabric version upgrade
  • Network productivity metrics, performance benchmarking and tuning
  • Parameters tuning by Kafka cluster design
  • Managing of Hyperledger containers
  • Security assurance
  • Troubleshooting

Day 2



Chaincode patterns used in popular business functions

  • Automotive supply chain: spare parts provenance and tracking chaincode (Golang)
  • National depository: bonds issuance and P2P transfer (Golang)
  • (Re)insurance: integration with external systems (Java)
  • Over-the-counter trading: implementation of “private collections” introduced in the HLF v1.2 (Golang)
  • License management platform: chaincode integration with the notification system (Golang)
  • Useful techniques:
    • Interaction between chaincodes: read-only queries within a channel and between two channels, use case examples
    • Hyperledger Fabric events usage: events mechanism, use case examples
  • Difference between implementing chaincode in Golang and Node.js and best practices
  • Algorithmics: how to write efficient chaincode and avoid typical mistakes

Chaincode interaction with various types of data sources (including ERP and CRM systems)

  • On-chain / off-chain data
  • Push vs. pull scenarios for reading the external data by the chaincode

Chaincode version upgrade on a running network


Day 3



Integration of Hyperledger Fabric with external apps

  • Data feeds from oracles
  • Interaction with payments systems, e-commerce platforms
  • IoT and blockchain

Web and mobile interface as an integral part of blockchain app

  • Integration of the UI with the blockchain layer: best practices

Q&A session
