Hyperledger Besu

Build on Hyperledger Besu the Easy Way

Kaleido simplifies Hyperledger Besu development, making it possible to create powerful blockchain networks and digital assets in a fraction of the time, at a fraction of the cost.
What it is

A Powerful, Flexible Platform for Hyperledger Besu Development

What It Is

Hyperledger Besu is an Open Source project designed with a modular architecture to meet the requirements of Enterprise Ethereum projects. Originally incubated under codename Pantheon, Kaleido collaborated closely with the original PegaSys engineering team throughout the project within the ConsenSys ecosystem of projects.

Having an independent codebase, written from scratch in Java with Enterprise in mind, provides great opportunities for innovation for this fast paced project. Hyperledger Besu is ready for your Enterprise network workloads.

Secure Permissioning

Leverage the most advanced permissioning functionality to easily manage account and node whitelisting, smart contracts and authenticated JSON-RPC calls.

Dependable Privacy

Ensure state consistency and have direct control over shared private data with flexible privacy groups.

Familiar Tooling

Intuitive features to deliver easy on-boarding and scalability, like Java based tools.

How it works

How it Works

Hyperledger Besu, Simplified

Besu is an Ethereum implementation purpose-built for enterprise use. Like the other Ethereum implementations, Besu is also compliant with the Ethereum yellow paper. Implemented in Java, Besu has a robust code base lineage that should give enterprise IT teams a relatively easy time to review for security.


Enterprise blockchain networks require efficient consensus algorithms, with high throughput characteristics, built-in permissioning, and predictable behaviour.

  • Clique PoA: Provides byzantine fault tolerance, coping with large numbers of permissioned signers through a simple and effective strategy of deciding on block proposers, optimised to minimize (but not prevent) short-lived forks
  • Istanbul Byzantine Fault Tolerance (IBFT): Byzantine fault-tolerant consensus algorithm, with immediate finality, and permissioning

Hyperledger Besu is Open Source, Java based and Apache 2.0 licensed.
