Besu Enterprise Ethereum Client

What is Hyperledger Besu?

Hyperledger Besu is an open-source Ethereum client developed under the Apache 2.0 license and written in Java. It runs on the Ethereum public network, private networks, and test networks such as Rinkeby, Ropsten, and Görli. Besu implements Proof of Work (Ethash) and Proof of Authority (IBFT 2.0 and Clique) consensus mechanisms.

You can use Besu to develop enterprise applications requiring secure, high-performance transaction processing in a private network.

Besu supports enterprise features including privacy and permissioning.

What can you do with Besu?

Besu includes a command line interface and JSON-RPC API for running, maintaining, debugging, and monitoring nodes in an Ethereum network. You can use the API via RPC over HTTP or via WebSockets, and Pub/Sub is supported. The API supports typical Ethereum functionalities such as:

  • Ether mining
  • Smart contract development
  • Decentralized application (Dapp) development

What does Besu support?

The Besu client supports common smart contract and Dapp development, deployment, and operational use cases, using tools such as Truffle, Remix, and web3j. The client supports common JSON-RPC API methods such as eth, net, web3, debug, and miner.

Besu doesn’t support key management inside the client. You can use EthSigner with Besu to provide access to your key store and sign transactions.
