Hyperledger Besu

What is Hyperledger Besu

Hyperledger Besu is an Open Source and Community Supported Ethereum client designed to be enterprise-friendly for both public and private permissioned network use cases, with an extractable EVM implementation. It can also be run on test networks such as Sepolia and Görli. Hyperledger Besu includes several consensus algorithms including Proof of Stake, Proof of Work, and Proof of Authority (IBFT 2.0, QBFT, and Clique). Its comprehensive permissioning schemes are designed specifically for use in a consortium environment.

Benefits of Hyperledger Besu:

Hyperledger Besu’s strengths lie in its compatibility with Ethereum, support for private transactions, flexibility in consensus mechanisms, and robust security features, making it a versatile choice for enterprises looking to leverage blockchain technology:

  • Ethereum Compatibility: Besu is compatible with the Ethereum public network, which means it supports all major Ethereum standards, smart contracts, and decentralized applications (DApps).

  • Support for Private Networks: Besu is particularly well-suited for private or permissioned blockchain implementations, making it ideal for enterprises that require privacy and permissioning features.

  • Consensus Mechanisms Flexibility: It supports various consensus mechanisms including Proof of Work (PoW), Proof of Authority (PoA), and more.

  • Privacy Features: Enable private transactions and private contracts. These features are crucial for businesses that need to keep certain information confidential, such as transaction value, sender, and receiver.

  • Performance and Scalability: Besu is designed to be performant and scalable, capable of handling large numbers of transactions typical in enterprise settings.

  • API Support: It offers extensive API support, including JSON-RPC, which is the standard Ethereum API, making it easy to integrate with existing systems and tools.

  • Security: Being developed under the Hyperledger umbrella, Besu has a strong focus on security, which is critical for enterprise applications.

Hyperledger Besu Architecture

The client architecture consists of three main components: Ethereum core, Storage, and Execution engine. Some of the client’s main features, including the EVM and consensus, are part of the Ethereum core. The EVM is supported by two additional components – a transaction processor and a block validator – which help it run more efficiently. The Ethereum core also includes a transaction pool responsible for storing transaction-related information and a synchronizer, which facilitates the synchronization between the nodes and the network.

While the core client architecture is relatively simple, it can be easily expanded with plugins. This approach is what enables Hyperledger Besu’s modularity. People can use some of the existing open-source Besu plugins or build their own plugins with the help of the Plugin API, which provides access to interfaces facilitating plugin development. The Plugin API also allows developers to take data from any Besu network and then feed it to their own applications and systems.
