Network deployment & configuration

Evm-based private networks (besu, quorum)

Users can configure the following parameters before deploying a private permissioned EVM-based network:

Genesis block configuration

The genesis.json file is a critical component of EVM-based blockchain networks, defining the initial state and parameters of the blockchain to ensure secure and structured network operations. Key elements include:

• Chain ID: Uniquely identifies the network to prevent replay attacks.
• Consensus Mechanism: Determines how blocks are validated, providing the necessary governance structure (e.g. QBFT, PoA, PoS).
• Pre-allocated Balances: Specify the initial allocation of tokens for specific addresses.
• QBFT Validator Information: Defines the nodes responsible for validating transactions in Quorum Byzantine Fault Tolerance (QBFT)-based networks.

Developer integrations

The SettleMint Network Manager provides developer-friendly tools to facilitate smart contract development and network interactions:

• Faucet Wallets: Enable test token distribution for private networks, making it easier for developers to test transactions.
• Genesis file availability: Users can access and download genesis.json file, allowing for easy network expansion outside SettleMint platform.

Hyperledger fabric networks

Users can configure the following settings before deploying a Fabric network:

Channel configuration and policies

Hyperledger Fabric networks use a configtx.json file to define network channels, membership rules, and policies. Key components include:

• Application Group: Defines policies for participating organizations, specifying details such as:
  • Organization Name
  • Policies:
    • Admin: Roles allow users to modify configurations.
    • Endorsement: Policies require transaction approvals from specific peers.
    • Readers and Writers: Policies define access to channel data.
• Orderer Group: Configures the ordering service responsible for transaction finalization. Settings include:
  • Batch Timeout: Determines the time before transactions are grouped into a block.
  • Max Messages Per Batch: Controls block size.
• Consensus Type: Typically etcdraft, a Raft-based ordering service.

Network governance and security

Hyperledger Fabric networks require robust security and governance mechanisms:

• Membership Service Provider (MSP): Controls identity verification and authentication, ensuring only authorized participants can access the network.
• Root Certificates and TLS Certificates: Define trusted entities for secure communication.
• Endorsement Policies: Determine how transactions are validated across organizations, enforcing compliance and preventing unauthorized modifications.
• Block Validation Policies: Ensure the integrity and security of the distributed ledger, maintaining network trustworthiness.
