In chapter 2, the author describes Hyperledger Fabric and its components. Create a new thread, choose one of the Hyperledger design principles described in chapter 2, and explain why your chosen design principle is important to a successfully enterprise blockchain implementation. I’m interested to read what YOU learned from this week’s reading. Do NOT submit a research paper. Tell me what you think.
Then think of three questions you’d like to ask other students and add these to the end of your thread.

Chapter 2
• Exploring Hyperledger Fabric
• Frameworks, tools, and building blocks
• Component design
• Sample transaction lifecycle
• Governance in business networks
Fundamentals of the
Hyperledger Project
• Open source technology development
The Linux Foundation
• Open source project • Purpose is to advance cross-
industry blockchain
Hyperledger
Open Source /
Open Standards
Lower cost of software consumption
Innovation and extensibility
Sustainable development and innovation stream
Security and reliability
Speeds up development and market adoption
Hyperledger Frameworks
Iroha – mobile development projects
Sawtooth – focus is versatility, includes a new consensus algorithm (Proof of Elapsed Time)
Burrow – meets the Ethereum Virtual Machine (EVM) specification
Fabric – general blockchain foundation
Indy – support for independent identites
Frameworks and Tools
Hyperledger Tools
Explorer – view blockchain data
Cello – implements a blockchain service
Composer – collaboration tools for blockchain development
Quilt – integration protocol
Caliper – blockchain benchmark tool
Blockchain building blocks
Hyperledger Fabric Components
Principles of Hyperledger
Design
MODULAR AND EXTENSIBLE APPROACH
INTEROPERABILITY FOCUS ON SECURE SOLUTIONS
TOKEN AGNOSTIC APPROACH
FOCUS ON RICH AND EASY-TO-USE
APIS
Hyperledger Fabric Reference Architecture
Hyperledger Fabric Runtime Architecture
Advantages of
component- based design
Separates development design from runtime
Discerning between design imperatives and deployment capabilities
Incorporates network design principles
Addresses channel design principles
Adopts Hyperledger Fabric composer model-driven development
Journey of a Sample Transaction
Hyperledger Fabric Actors
Developer Interaction
Governance
Body that establishes rules
Blockchain governance is distributed
• Degree of distribution depends on cooperation between nodes
Aspects of blockchain governance
• IT governance (risk)
• Network governance
• Business network governance
Summary
• Hyperledger Fabric – modular blockchain
• Understanding the modular approach and main components is important
• Transaction flow
• Endorsement
• Ordering
• Validation
• Governance is necessary to maintain blockchain network operation
