Module 4: Network Configuration and Deployment

4.2 Network Configuration

Configuring a Hyperledger Fabric network involves defining the network topology, organizations, channels, and policies. This section covers the key configuration aspects and tools used to set up a Fabric network.

Network Topology Design

When designing a Hyperledger Fabric network topology, several factors need to be considered:

Organization Structure

  • Number of Organizations: Determine how many organizations will participate in the network
  • Roles: Define which organizations will host orderers, peers, or both
  • Domains: Assign domain names to each organization (e.g., org1.example.com)
  • Hierarchies: Consider if organizations have parent-child relationships

Node Distribution

  • Orderer Nodes: Decide on the number and distribution of orderer nodes
  • Single orderer (for development)
  • Multiple orderers with Raft consensus (for production)

  • Peer Nodes: Determine the number and types of peers per organization

  • Endorsing peers (execute chaincode)
  • Committing peers (validate and commit transactions)
  • Anchor peers (enable cross-organization communication)

  • Geographic Distribution: Consider distributing nodes across different regions for resilience

Network Sizing

  • Transaction Volume: Estimate expected transactions per second
  • Data Volume: Project the growth of the ledger over time
  • User Base: Consider the number of concurrent users
  • Chaincode Complexity: Factor in the computational requirements of chaincode

Cryptographic Material Generation

Hyperledger Fabric uses X.509 certificates for identity and TLS communication. The cryptogen tool generates these certificates for development environments.

Using cryptogen

  1. Create a crypto-config.yaml file:
OrdererOrgs:
  - Name: Orderer
    Domain: example.com
    Specs:
      - Hostname: orderer
      - Hostname: orderer2
      - Hostname: orderer3

PeerOrgs:
  - Name: Org1
    Domain: org1.example.com
    EnableNodeOUs: true
    Template:
      Count: 2
    Users:
      Count: 1

  - Name: Org2
    Domain: org2.example.com
    EnableNodeOUs: true
    Template:
      Count: 2
    Users:
      Count: 1
  1. Generate the cryptographic material:
cryptogen generate --config=./crypto-config.yaml --output=./crypto-config

This command creates: - MSP directories for each organization - TLS certificates for secure communication - User certificates for administrators and regular users - Peer and orderer node certificates

Directory Structure

The generated cryptographic material follows this structure:

crypto-config/
├── ordererOrganizations/
│   └── example.com/
│       ├── ca/
│       ├── msp/
│       ├── orderers/
│       │   ├── orderer.example.com/
│       │   ├── orderer2.example.com/
│       │   └── orderer3.example.com/
│       ├── tlsca/
│       └── users/
│           └── Admin@example.com/
└── peerOrganizations/
    ├── org1.example.com/
    │   ├── ca/
    │   ├── msp/
    │   ├── peers/
    │   │   ├── peer0.org1.example.com/
    │   │   └── peer1.org1.example.com/
    │   ├── tlsca/
    │   └── users/
    │       ├── Admin@org1.example.com/
    │       └── User1@org1.example.com/
    └── org2.example.com/
        ├── ...

Production Considerations

For production environments, use Fabric CA instead of cryptogen: - Set up a root CA and intermediate CAs - Register and enroll identities - Implement certificate renewal and revocation - Secure private keys with HSMs (Hardware Security Modules)

Genesis Block and Channel Configuration

The configtxgen tool is used to create the genesis block for the orderer and channel configuration transactions.

configtx.yaml

Create a configtx.yaml file that defines:

Organizations:

Network Configuration Best Practices

When configuring a Hyperledger Fabric network, follow these best practices:

  1. Security
  2. Use TLS for all communications
  3. Implement proper access control with MSPs
  4. Secure private keys, especially for CAs
  5. Use separate networks for orderer and peer organizations

  6. Performance

  7. Optimize batch size and timeout for transaction throughput
  8. Configure appropriate resource limits for containers
  9. Use CouchDB for complex queries
  10. Implement proper caching strategies

  11. Scalability

  12. Design for horizontal scaling of peers
  13. Use multiple orderers with Raft consensus
  14. Implement proper load balancing
  15. Consider channel design for data isolation

  16. Maintainability

  17. Document network configuration
  18. Use version control for configuration files
  19. Implement automated deployment
  20. Create backup and recovery procedures

  21. Monitoring

  22. Enable metrics collection
  23. Set up logging aggregation
  24. Implement health checks
  25. Create alerting for critical issues

By following these configuration guidelines, you can create a robust and secure Hyperledger Fabric network that meets your business requirements. In the next section, we'll explore how to deploy and manage this network.
