Hyperledger Besu is Hyperledger's Principal Ethereum project. It is focused around 3 key pillars: a fully functional client for public networks, a customizable client for private networks, and libraries to support the use of Ethereum technologies in Besu and other projects.
- Fully Functional Client for Public Networks
Besu explicitly and "out fo the box" supports the following networks, including planned future upgrades- Ethereum Mainnet
- Pre-Merge Ethash Proof-of-Work Client
- Post-Merge Execution Client, pairablre with any fully-functional Consensus Client such as Lighthouse, Loadstar, Nimbus, Prysm, or Teku
- Ethereum Mainnet Testnets
- Ethereum Classic
- Ethereum Classic Testnets
- Ethereum Mainnet
- Customizable Client for Private Networks
- Multiple Consensus Engines such as Clique, IBFT2, or QBFT.
- Optional private transaciton technology
- Optional Integration with Privae Enclaves such as Tessera
- Optional Node Access
- Libraries to support the use of Ethereum technologies
- EVM Engine Library
To support these 3 pillars are the following 6 systems.
- EVM Engine
- Consensus Protocols
- Peer-to-peer communications
- JSON-RPC Communications
- Data Storage
- Block Production
