Ethereum implementation built from scratch to meet Enterprise requirements


Pantheon is an Open Source project maintained by PegaSys, designed with a modular architecture to meet the requirements of Enterprise Ethereuem projects. Kaleido has collaborated closely with the PegaSys team throughout the project within the ConsenSys ecosystem of projects, and we are excited to make it available as the newest addition to our protocol option.

Having an independent codebase, written from scratch in Java with Enterprise in mind, provides great opportunities for innovation for this fast paced project.

Pantheon is ready for your Enterprise network workloads.


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 finality, and permissioning



Allow only trusted nodes to participate in the blockchain

Transaction/Contract Privacy

Quorum allows contracts to be deployed and transactions to be sent to a subset of participating nodes in the blockchain.

IBFT consensus

Proof of authority based consensus which provides immediate block finality, reduced time between blocks and high data integrity and fault tolerance.

Clique/POA consensus

Proof of authority based consensus. Instead of miners racing to find a solution to a difficult problem, authorized signers create new blocks in a synchronized manner.
