Launch a Hyperledger Fabric network on our platform and enjoy powerful REST APIs, flexible cloud deployment options, and advanced token management.
Our team includes founding members of Hyperledger Fabric, plus long time committers and maintainers. We serve on the technical steering committee for Hyperledger and are significant contributors to not only Fabric, but Hyperledger FireFly as well.
Because we know this technology well, we understand how important it is to give developers tools and APIs to make development easier. Our platform makes it radically simple to build blockchain applications on Fabric chains.
Launch a chain in minutes, while FabConnect, our open source REST API for simplifying Fabric interactions, makes it simple for any developer to manage a network without having to become a Fabric expert first.
Deploy an enterprise-grade network on AWS, Azure, or on-prem, and spend more time perfecting your use case and less time building the blockchain infrastructure.
Access all of the on-chain and off-chain services you need to get enterprise blockchain networks and applications to production.
Hyperledger Fabric is an open-source permissioned blockchain framework first developed by IBM and donated to the Linux Foundation in 2015. Initially used in supply chain and financial applications, it gained traction due to its modularity, privacy features, and versatility in designing business-specific blockchain solutions, making it a trusted choice for enterprise-grade applications. Kaleido’s team contains founding members of Hyperledger Fabric, plus long time committers and maintainers.
Hyperledger Fabric offers benefits such as modular architecture, support for multiple programming languages, private and secure channels, and the ability to plug in different consensus algorithms, making it flexible and adaptable to various business needs.
Hyperledger Fabric is a great protocol choice for tracking the provenance of goods along a supply chain, enhancing transparency and reducing fraud. It has also found broad adoption in financial services and healthcare, where its privacy capability and ability to securely share data helps streamline complex and sensitive operations. With a modular architecture, Fabric enables plenty of customizations to make blockchain-based collaboration easier and more efficient for enterprise businesses. Fabric is a great option if there are competitive or separate entities operating in one shared network as channels enable 1-to-1 interactions in dedicated, separate chains.
You can launch a Hyperledger Fabric chain in minutes on the Kaleido platform using the free trial, enjoying a full suite of plug and play tools and services, or download the source code to build your own chain.
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.
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 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.

Hyperledger Fabric is free to use. Developed by the Linux Foundation, it is open source and anyone can download it.
Yes. Hyperledger Fabric is designed for use in enterprise environments where multiple organizations need to collaborate and share data securely. Unlike public blockchains like Bitcoin or Ethereum, Hyperledger Fabric is permissioned, meaning that participants in the network are known and trusted entities.
In a Hyperledger Fabric network, organizations can maintain their own private channels for transacting and sharing data with specific parties, while also having the ability to interact with other channels when necessary. This allows for greater privacy, scalability, and flexibility in designing blockchain-based solutions for business use cases.
Furthermore, Hyperledger Fabric provides a modular architecture, enabling organizations to customize various aspects of the network, such as consensus mechanisms, membership services, and data storage, to fit their specific requirements.
Hyperledger Fabric follows a modular architecture, providing flexibility and customization options for consensus, membership services, and smart contracts (chaincode). It supports pluggable consensus mechanisms and allows transactions to be endorsed by selected participants, enabling privacy and complex transaction workflows. Chaincode can be written in languages like Go, Java, and JavaScript.
In contrast, Hyperledger Sawtooth focuses on simplifying distributed application development. It utilizes a transactional architecture and the Proof of Elapsed Time (PoET) consensus algorithm, leveraging trusted execution environments for scalability and energy efficiency. Sawtooth supports smart contract development in multiple languages such as Python, JavaScript, and Rust.
Hyperledger Fabric emphasizes permissioned access control, making it suitable for enterprise consortia and business networks. It offers greater privacy, scalability, and flexibility. On the other hand, Hyperledger Sawtooth targets distributed application use cases, allowing experimentation and customization through a modular design.
Both frameworks have their strengths and can be adapted to various enterprise blockchain scenarios. The choice between them depends on specific project requirements, such as the need for privacy, the complexity of transaction workflows, language preferences for smart contract development, and the focus on distributed application development versus enterprise consortia use cases.
To write and deploy smart contracts (chaincode) on Hyperledger Fabric, you need to choose a programming language such as Go, Java, or JavaScript and set up the development environment accordingly. Write the chaincode logic, defining functions and data structures, using the Fabric SDKs and APIs. Package the chaincode into a deployable format and install it on desired peer nodes within the network. Instantiate the chaincode on a specific channel to bind it to the network. Finally, interact with the deployed chaincode using client applications, SDKs, or RESTful APIs by invoking its functions and passing relevant data as arguments. It's recommended to refer to the official Hyperledger Fabric documentation and language-specific resources for detailed instructions and best practices in writing and deploying chaincode on the platform.
In our libray of webinars, you can watch a video tutorial about this process from Jim Zhang titled "Tech Tuesday: How to Write and Deploy Chaincode for Hyperledger Fabric."
