  • • MSP/CA integration with local credential store:
    • MSP/CA user authentication vs. API-managed user authentication
    • LDAP

Network administration

Day 2

Topic

Description

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
