What is Quorum?

Quorum was developed by JPMorgan in 2016 and was initially adopted in finance for secure transactions. Its privacy features, compatibility with Ethereum, and enterprise focus attracted industries needing confidentiality and robust blockchain solutions.

What are the benefits of Quorum?

Quorum offers enhanced privacy through its use of Tessera, a privacy layer that encrypts transaction data. It also provides increased throughput due to its consensus algorithm and is customizable for different use cases.

What are top Quorum Use Cases?

Quorum blockchain is used in finance, enabling secure and transparent transactions through smart contracts. In supply chain management, it assures traceability and trust, preventing fraud. While its privacy features make it ideal for industries requiring confidentiality. Quorum is Ethereum compatible, ensuring advanced interoperability and integration with other blockchain systems.

How to get started with Quorum?

You can launch a Quorum chain in minutes on the Kaleido platform using the free trial, enjoying a full suite of plug and play tools and services, or access the source code to build a chain or application of your own.

The Benefits of Quorum

Quorum is a blockchain protocol specially designed for use in a private blockchain network, where there is only a single member owning all the nodes or a consortium blockchain network where multiple members each own a portion of the network.


Quorum is designed to be highly scalable, with low transaction latencies and the ability to support a higher number of transactions per second than other blockchain protocols. This makes it well-suited for use in high-volume applications.


Quorum includes a number of security features that are designed to protect sensitive or proprietary data, like private transactions that allow network participants to transact without revealing the details of their transactions to the rest of the network.


Quorum is based on the Ethereum protocol and can support a wide range of decentralized applications and smart contracts. It is also highly modular and customizable so that it can be tailored to the needs of specific use cases.

Gas-Free Transactions

There is no cost required to submit transactions to a Quorum network, unlike Ethereum, which requires the payment of high and unpredictable gas fees to submit transactions.

Common Questions about Quorum

What is Quorum?

Quorum is an open-source, permissioned blockchain protocol based on Ethereum that was developed by J.P. Morgan to meet the needs of financial institutions and other enterprises interested in blockchain technology. In 2020, Quorum was acquired by ConsenSys, which currently manages its development.

Like Ethereum, Quorum allows developers to build and deploy decentralized applications (dApps) and smart contracts. However, Quorum has been optimized for enterprise use cases and is designed to support private, permissioned blockchain networks. This means that it is used to build blockchain networks where all participants are known and trusted, rather than being open to the general public like the Ethereum mainnet.

Quorum is designed to be highly scalable and secure, with a number of features that make it useful in applications where privacy and security are paramount. For example, it includes support for private transactions, which allow parties to transact without revealing the details of their transactions to the rest of the network. It's voting-based consensus mechanisms are also more enterprise friendly and support higher throughput than other consensus mechanisms

Overall, Quorum is a useful protocol for enterprises that want to build decentralized applications on permissioned blockchain networks.

What is the difference between Quorum and Ethereum?

The main difference between Ethereum and Quorum is that Ethereum is a public, permissionless blockchain, while Quorum is a private, permissioned blockchain. This means that anyone can participate in the Ethereum network and access its features, while access to Quorum networks are restricted to specific, approved participants.

Quorum also includes a number of features that are specifically designed for enterprise use cases, such as support for private transactions and voting-based consensus mechanisms. These features make Quorum well-suited for use in applications where privacy and security are key concerns.

Overall, Ethereum and Quorum are both useful tools for building decentralized applications and smart contracts, but they are designed for different purposes and may be better suited for different use cases depending on the specific requirements of the project.

Is Quorum free?

Yes, Quorum is open-sourced under the Apache 2.0 license and is free to download and use. It is developed and maintained by ConsenSys and a community of contributors, and can be downloaded from the Quorum GitHub.

However, while the software itself is free, there are costs associated with using Quorum. This includes the cost of the hardware and hosting needed to deploy an application on Quorum, as well as the cost of hiring developers to build and maintain decentralized applications on the platform.

Kaleido can help you deploy your Quorum app cost effectively across geographies and clouds with plans available for every stage of development. Kaleido also features a full suite of plug-and-play services and APIs that make it easier to build on Quorum, helping you save on development costs and get your app to production quickly.

How long does Kaleido plan to support Quorum?

Because we've built a chain-agnostic platform and made our tools available to developers regardless of how they choose to deploy their blockchain applications, we plan to support QBS projects well into the future.
