We've Built Quorum with Everything You Need

Permissioning and Privacy

The Quorum open source protocol layer enables businesses to build on public or private Ethereum networks, ensuring our solution fits any potential regulatory and security requirements.

Consensus Mechanisms

Both the Hyperledger Besu and GoQuorum variants support Proof of Authority (IBFT and Clique) consensus mechanisms, while Besu also supports Proof of Work (EthHash) for the Ethereum Mainnet, and GoQuorum also supports RAFT ordering.

Production-Ready

Quorum provides familiar connectivity to monitor the performance and uptime of enterprise solutions. Monitoring, logging and event streaming for High Availability, and database backups for Disaster Recovery are all supported by Quorum projects.

Ecosystem Compatibility

We work with the existing tools you know: Truffle, MetaMask, Remix, OpenZeppelin, and more. Quorum now has compatible options for the Ethereum Mainnet.

Quickstarts and Support

Robust documentation is available for the entire Quorum open source layer. Documentation is maintained by the ConsenSys team and support is always available.
