Introduction
As we move to the end of 2024, the enterprise blockchain landscape continues to evolve, with Hyperledger Besu and Hyperledger Fabric adapting to meet changing market demands. While the initial hype around blockchain has settled, these platforms have found their niches in specific industries and use cases.
Recent developments highlight both progress and challenges:
-
Hyperledger Besu has seen increased adoption in decentralized finance (DeFi) applications, leveraging its Ethereum compatibility. However, it faces competition from layer-2 scaling solutions and alternative Ethereum clients.
-
Hyperledger Fabric remains a go-to for supply chain management, with notable implementations by Walmart and Maersk. Yet, concerns about complexity and steep learning curves persist.
-
Both platforms are addressing scalability and interoperability issues, with Besu exploring rollup technologies and Fabric enhancing its channels architecture.
-
Privacy remains a key focus, with zero-knowledge proofs being integrated into both platforms to meet stringent data protection requirements.
It's worth noting that enterprise blockchain adoption has been slower than initially predicted. A 2023 Gartner report suggests that only 5% of enterprise blockchain projects make it to production, highlighting the need for careful evaluation of use cases.
This blog post will compare Hyperledger Besu and Fabric, examining their current capabilities, limitations, and suitability for different enterprise needs.
Key Takeaways

- Hyperledger Fabric is a modular blockchain framework for developing enterprise-grade applications.
- Both platforms offer unique features catering to different enterprise blockchain needs.
- The choice between Besu and Fabric depends on specific project requirements and use cases.
- Understanding the differences is crucial for organizations looking to implement blockchain solutions.
Understanding Hyperledger Besu and Hyperledger Fabric
Hyperledger Besu
Hyperledger Besu is an open-source Ethereum client developed under the Hyperledger umbrella. It is designed to be enterprise-friendly, catering to both public and private permissioned network use cases. Besu implements the Ethereum protocol and can be run on the Ethereum public network, private networks, and test networks such as Rinkeby, Ropsten, and Görli.
Hyperledger Fabric
Hyperledger Fabric, on the other hand, is a modular blockchain framework that serves as a foundation for developing enterprise-grade applications and solutions. It provides a unique approach to consensus that enables performance at scale while preserving privacy. Fabric is designed to support pluggable implementations of different components and accommodate the complexity and intricacies that exist across the economic ecosystem.
Core Components of Hyperledger Besu and Fabric
Hyperledger Besu Components
- Ethereum Virtual Machine (EVM): Executes smart contracts
- Consensus Mechanisms: Supports multiple algorithms including PoW, PoA, and IBFT 2.0

Hyperledger Fabric
Fabric employs a unique architecture:
- Execute-Order-Validate: Separates transaction execution from ordering and validation
- Endorsement policies: Define which peers need to execute and validate a transaction
- Private Data Collections: Allow a subset of organizations to keep data private from others
Security and Privacy Aspects
Hyperledger Besu
- Supports private transactions using Tessera
- Implements network permissioning for access control
- Utilizes Ethereum's cryptographic security measures
Hyperledger Fabric
- Offers fine-grained access control through channels and private data collections
