Hyperledger Fabric 3.0 is Released

 

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:

1. 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.
2. Performance Improvements: Building on version 2.5, Fabric 3.0 offers enhanced performance, speed, and privacy for enterprise blockchain deployments.
3. Modular Architecture: The update continues to leverage Hyperledger Fabric’s modular architecture, providing flexibility and customization to meet diverse enterprise needs.
4. Enhanced Security and Reliability: The integration of the SmartBFT consensus library increases network resilience and reliability, making it more robust against potential failures.
5. 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.

Convergence of Blockchain and Artificial Intelligence (AI)

 

The timeline of AI and Blockchain convergence is divided into three eras:

1.Emerging: The initial phase where the technologies are developed independently.

2.Convergence: The current phase where the technologies begin to integrate, focusing on data manipulation, legacy system applicability, and hardware issues.

3.Application: The future phase where the integrated technologies will impact various sectors like cybersecurity, finance, energy, and smart cities.

This convergence is expected to create more secure, privacy-preserving digital environments and is predicted to significantly grow in market size. The union of AI and blockchain signifies a leap forward in creating robust frameworks for data integrity and establishing trust in AI systems, marking a new era of technological advancement.

Below is the summary how this convergence can address real time business problems.

• AI and Blockchain as Agents of Change: Both AI and blockchain are transforming their respective fields, offering new ways to address the challenges of the digital age.
• Synergistic Relationship: The integration of AI with blockchain amplifies their strengths, leading to increased trust, transparency, and efficiency in AI, and improved operations and security in blockchain.
• Enhanced Capabilities: AI’s data analysis and decision-making process, combined with blockchain’s decentralization, transparency, and security, can foster innovative solutions.
• Addressing Challenges: This convergence can tackle technological and societal issues, such as money laundering and terrorism financing, by optimizing operations and enhancing security.
• Revolutionizing Sectors: The fusion of AI and blockchain is set to revolutionize various industries by introducing new paradigms in data management, automation, and secure, decentralized operations.
