Since launching in 2015, Hyperledger Fabric has been a top choice for enterprises looking to build apps on permissioned blockchain networks. The modular architecture is capable of powering large-scale applications that require enterprise-grade data security.
The ability to protect certain details of peer transactions has made Hyperledger Fabric a go-to protocol for industries like financial services, supply chains, and the insurance industry. It works for complex use cases that involve personally identifiable information and proprietary business data.
Hyperledger Fabric is one of the many protocol choices available on Kaleido. With a full suite of plug and play services, flexible cloud deployment options, and powerful APIs, Kaleido is the easiest way to run a Fabric network anywhere.
Hyperledger Fabric is an open source project designed to handle enterprise-grade use cases. Key differentiators are its quick transaction throughput and its modularity, allowing for more innovation and optimization regardless of industry use cases. Other benefits include scalability and security, key pillars of any enterprise application.
Hyperledger Fabric is a modular blockchain framework that allows you to plug in different components, such as consensus algorithms and membership services, and tailor networks to your needs
Part of the Hyperledger project of the Linux Foundation, Hyperledger Fabric is an open source protocol that allows the enterprise to build custom applications and limit vendor risks
With a high level of security for enterprise users, Fabric uses a permissioned network to prevent unauthorized access

Talk to an ExpertQuorum 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.
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.

Talk to an ExpertMaintained 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:
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.
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.
Quorum is a protocol of choice for industries like financial services, insurance, and supply chain management where enterprise-grade.
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.
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.
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.
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.
