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.

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
