What is the "Hyperledger Besu"?

Hyperledger Besu

- Java-based Ethereum client

- Open source, Apache 2.0 license

- It can be run on the Ethereum public network or on private permissioned networks.

- PoW, PoA, IBFT, Clique

 

Ethereum Client

- Software that implements the Ethereum protocol

- It contain follows

• An execution environment for processing transactions in the Ethereum blockchain
• Storage for persisting data related to transaction execution
• P2P networking for communicating with the other Ethereum nodes on the network to synchronize state
• APIs for application developers to interact with the blockchain

Hyperledger Besu's Features

- Implements the Enterprise Ethereum Alliance(EEA)

- Hyperledger Besu's features include

• The Ethereum Virtual Machine (EVM) : The EVM is the Turing complete virtual machine
• Consensus Algorithms : PoW(Ethask), PoA(IBFT 2.0, Clique)
• Storage : Blockchain, World State
• P2P networking : Ethereum's devp2p network protocols for inter-client communication and an additional sub-protocol for IBFT2
• User-facing APIs : JSON-RPC(HTTP JSON-RPC service, WebSocket JSON-RPC service), GraphQL
• Monitoring : use Prometheus or debug_metrics JSON-RPC API method
• Privacy : Privacy in Besu refers to the ability to keep transactions private between the involved parties
• Permissioning : simliar to Hyperledger Fabric Channel (From what I understand)

What does Hyperledger Besu support?

- includes a command line interface as well as HTTP- and WebSocket-based APIs for running, maintaining, and monitoring nodes in an Ethereum network

- Besu client's APIs supports typical Ethereum functionalities, the client implements standard JSON-RPC APIs

- Besu doesn't support key management within the client due to security concerns

- EthSigner(access to key store, sign transactions) or any Ethereum-compatible wallet for managing private keys
