Hyperledger Besu is an open-source blockchain platform developed under the Hyperledger project of the Linux Foundation. It is designed to provide a robust, secure, and highly performant platform for building decentralized applications (dApps) and smart contracts.
What is Hyperledger Besu ?
Hyperledger Besu is a permissioned blockchain platform, meaning that access to the network is restricted to authorized participants, and the platform is designed for enterprise use cases where privacy and security are critical requirements. Hyperledger Besu supports both public and private networks, and it is fully compatible with the Ethereum blockchain and its ecosystem, including support for Ethereum Virtual Machine (EVM) and the Solidity programming language.
Hyperledger Besu is unique in that it offers both the security and privacy of a permissioned blockchain, as well as the flexibility and compatibility of a public blockchain. This makes it an ideal platform for enterprise use cases where decentralized applications need to be deployed in a secure and private environment, but also need to interoperate with other blockchain networks and technologies.
Hyperledger Besu Consensus Algorithms
Hyperledger Besu supports several consensus algorithms, including:
- Proof of Work (PoW): Proof of Work is a consensus algorithm used in public Ethereum networks and is the default consensus algorithm for Hyperledger Besu when running in public mode. It uses mining to reach a consensus on the state of the blockchain.
- Clique PoA (Proof of Authority): Clique PoA is a consensus algorithm used in private Ethereum networks, where a set of authorized nodes, or authorities, validate transactions and blocks. It is more suitable for private networks where the identities of the validating nodes are known and can be trusted.
- IBFT 2.0 (Istanbul Byzantine Fault Tolerance): Istanbul Byzantine Fault Tolerance is a consensus algorithm used in private Ethereum networks that provides high performance and finality. It is a BFT-style consensus algorithm that uses voting by validating nodes to reach consensus.
- Aura PoA (Proof of Authority): Aura PoA is a consensus algorithm used in private Ethereum networks where a single authority is responsible for validating transactions and blocks. It is suitable for networks where a single entity needs to have complete control over the validation process.
How Does Hyperledger Sawtooth Work?
Hyperledger Besu works by using a consensus algorithm to validate transactions and maintain the state of the blockchain. The consensus algorithm used depends on the configuration of the network and can be either Proof of Work (PoW), Clique PoA (Proof of Authority), IBFT 2.0 (Istanbul Byzantine Fault Tolerance), or Aura PoA (Proof of Authority).
- In a public network using PoW, transactions are validated and added to blocks by a decentralized network of miners who compete to solve a mathematical puzzle to validate transactions and create new blocks.
- In a private network using PoA, transactions are validated by a set of authorized nodes, or authorities, who are selected by the network operator.
Once transactions are validated and added to a block, the block is broadcast to the network and added to the blockchain. A distributed ledger called the blockchain keeps track of all transactions and offers a safe and unalterable history of the network’s status.
Smart contracts, which are self-executing computer programs that operate on the blockchain and uphold the network’s regulations, are also supported by Hyperledger Besu. Smart contracts can be employed to manage digital assets, enforce rules and laws, and automate corporate processes.

Hyperledger Besu at Work
Hyperledger Besu at work involves several steps:
- Setting up a network: Hyperledger Besu can be used to create a private or public network, depending on the use case and the requirements of the network. The network can be set up using a pre-configured Docker image or by building from the source.
- Deploying Smart Contracts: Once the network is set up, smart contracts can be deployed using the Solidity programming language. Smart contracts are self-executing computer programs that run on the blockchain and enforce the rules of the network.
- Validation of Transactions: Transactions are validated and added to blocks by the consensus algorithm. In a public network using PoW, transactions are validated by a decentralized network of miners. In a private network using PoA, transactions are validated by a set of authorized nodes, or authorities, who are selected by the network operator.
- Creation of Blocks: Once transactions are validated, they are added to blocks and broadcast to the network. The blocks are then added to the blockchain, which is a distributed ledger that stores a record of all transactions and provides a secure and tamper-proof history of the state of the network.
- Execution of Smart Contracts: Smart contracts are executed on the blockchain when triggered by a transaction. Smart contracts automate business processes, enforce rules and regulations, and manage digital assets.
