The Linux Foundation Decentralized Trust has unveiled Hyperledger Fabric 3.0, introducing Byzantine Fault Tolerant (BFT) consensus to enhance decentralization for enterprise blockchain deployments. This update aims to bolster the reliability and security of blockchain networks, making them more robust for various applications. Key enhancements include:
- Byzantine Fault Tolerant (BFT) Consensus: Utilizing the SmartBFT protocol, this mechanism ensures network operation even if some nodes are compromised, maintaining blockchain integrity and consistency.
- Performance Improvements: Building on version 2.5, Fabric 3.0 offers enhanced performance, speed, and privacy for enterprise blockchain deployments.
- Modular Architecture: The update continues to leverage Hyperledger Fabric’s modular architecture, providing flexibility and customization to meet diverse enterprise needs.
- Enhanced Security and Reliability: The integration of the SmartBFT consensus library increases network resilience and reliability, making it more robust against potential failures.
- Enterprise-Grade Features: Fabric 3.0 supports complex, production-ready blockchain applications, suitable for a wide range of industry use cases.
To upgrade from Hyperledger Fabric 2.5 to 3.0, follow these steps:
- Backup: Ensure you back up the ledger and Membership Service Providers (MSPs).
- Upgrade Orderer Binaries: Perform a rolling upgrade of the Orderer binaries to the latest version.
- Upgrade Peer Binaries: Similarly, upgrade the peer binaries in a rolling fashion.
- Update Channels: Update the Orderer system channel and any application channels to the latest capability levels available.
