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.

Scalability

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.

Security

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.

Flexibility

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.

How it works

How it Works

Quorum, Simplified

Maintained as a collaborative fork of the most popular public Ethereum client (go-ethereum or ‘geth’), Quorum provides a number of extensions enabled in Kaleido to meet the needs of Enterprise grade production networks. Some things that make Quorum different include:

  • Privacy via private transactions: members of a Quorum network can send private transactions that are addressed to a subset of nodes, such that the contents of the transaction are not exposed to non-privy members.
  • Peer permissioning: a Quorum network can be configured to run in permissioned mode such that all nodes must be explicitly listed in an access control list enforced by all nodes. This prevents foreign nodes from tapping into the network and replicating blocks as is the case in permissionless networks.
  • Flexible consensus: described in greater detail later in this post, Quorum supports Raft and Istanbul BFT as valid consensus options. Both support transaction finality (i.e. lack of chain forking) and offer shorter block intervals than proof-of-work.

Private Transactions

In an Enterprise blockchain network it is common that some data cannot be shared with all participants. Quorum provides a model where encrypted data can be exchanged privately between participants, and stored privately in an enclave of only those participants allowed to see that data. The same Ethereum APIs and Smart Contract programming model is used to perform these private Blockchain transactions, as the transactions that are visible to all the participants.

A hash of the private data is written to the main ledger, recording the data that was sent. The private transaction manager component is called Tessera, and supersedes the previous transaction manager Constellation. Key new features include pluggable JDBC Database support, and the ability to externally sign and submit transactions. Tessera is provided as the default private transaction manager in all new Kaleido environments, and migration from Constellation to Tessera is automatic for all old environments.

Enterprise Use Cases
Run Better on Kaleido

Hyperledger Fabric is a private blockchain that allows developers to create subnets, or channels, meaning that certain proprietary or personal information can remain confidential. This makes Fabric a protocol of choice for industries like financial services, insurance, and supply chain management.

Supply Chains

Hyperledger Fabric networks can increase transparency and traceability of transactions within the network. This transparency can be used to monitor real-time location data, limit fraud and counterfeit goods, and track ESG efforts.

Digital Assets

Complex multi-party business networks built on Fabric can easily tokenize assets, transact instantly, share data, and eliminate cumbersome paperwork as financial business flows are automated.

Insurance

Moving insurance transactions to blockchain can eliminate fraud, automate claim processing, and digitize legacy systems. Hyperledger Fabric also allows stakeholders to automate Know Your Customer (KYC) processes via smart contracts.

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.
