Hyperledger Besu Ethereum client
Hyperledger Besu is an open source Ethereum client developed under the Apache 2.0 license and written in Java. It runs on public and private networks:
-
:material-book-open-variant: Public networks
Run Besu as an execution client on Ethereum Mainnet and Ethereum public testnets, such as Goerli and Sepolia.
-
:material-book-lock-outline: Private networks
Create or join a private, permissioned network. Use private networks to develop enterprise applications requiring secure, high-performance transaction processing.
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 WebSocket. Besu also supports Pub/Sub. 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 access your key store and sign transactions.
