Day 2
During the second day we learn about Hyperledger networks and deployment, get a deep dive into blockchain security and privacy and also speak about the most popular blockchain use cases. And, most importantly, get to the practical part of the training.
Application life-cycle management
- Customize the network
- Create a new channel
- Install & instantiate a new chaincode in the channel
- Modify or upgrade the chaincode
- Invoke the chaincode from the CLI
- Configure endorsement policy
Hyperledger Fabric multi-host deployment
Hyperledger Fabric multi-host deployment: Solo-Orderer & Raft
Advanced integration patterns
- External file storage (IPFS)
- External key generator (HSM)
- Hyperledger Caliper tools for the network performance measurement
- 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
Cryptography, Privacy, Security and Trust in blockchain systems: deep dive
- Definitions and protocols
- Zero knowledge proof (ZKP)
- Identity mixer (Idemix) implementation for Hyperledger Fabric
- Scripts for the Idemix customization at the chaincode level
- Intel SGX solution integrated with Hyperledger Fabric
Use cases
- IoT and logistic case
- Token Creation and Exchange
- Supply chain management
Practical Part
- HLF deployment on top of AWS
- High throughput chaincode. Key collision
