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.
Kaleido makes it possible to 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.
Our platform makes it easy to deploy an enterprise-grade network on AWS, Azure, or on-prem. This means you spend more time perfecting your use case and less time building the blockchain infrastructure.
Most Blockchain-as-a-Service (BaaS) providers stop at the blockchain. We provide all of the on-chain and off-chain services you need to get enterprise blockchain networks and services to production.
Kaleido makes it easy to build applications that go beyond a simple login to create an identity layer that gives people more control and portability of their data.
Kaleido offers identity as a service with hosting of both claim and verifier servers. Our platform then brings identity solutions to life with pre-built, pluggable services like wallets, tokens, and public and private connectivity. Meet the demands of the most complex use cases with fully customizable identity apps.
Built for permissioned networks
Data isolation and strict governance enabled by Hyperledger Fabric certificate authority
Unique Execute-Order-Commit endorsement model where transactions are initially executed on a set of peers while ordering service handles packaging and delivery
Ordering can be switched based on the needs of the environment with pluggable consensus algorithms
Go, Java, Node.js
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.

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
Kaleido is a Hyperledger Certified Service Provider (HCSP) with a deep expertise in helping enterprises successfully adopt Hyperledger tools. Our founding partners are also active with the Hyperledger Foundation. Sophia Lopez is a General Member representative on the Hyperledger Foundation Governing Board and Jim Zhang is a member of the Hyperledger Foundation Technical Oversight Committee.
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 ExpertWhen contrasted against other enterprise blockchain protocols, Fabric displays a number of inherently unique characteristics. These include transaction lifecycle and consensus, privacy techniques and channels, trust models, smart contracts, and programming paradigms.
Fabric employs an elaborate governance model backed by x.509 certificates (referred to as Membership Service Provider credentials) that is coupled with policy mandates responsible for enforcing a signature threshold.
Fabric transactions can be distilled into three distinct tiers:
Channels provide the first high level of privacy in Fabric. Only memberships that have been authorized to participate in a channel can join a peer node. The accompanying ledger and underlying state information remains completely isolated from every other member on the network.
Fabric also supports Private Data Collections whereby private information is shared directly via P2P amongst the privy participants. Only hashes of the private inputs are shared with the orderers for inclusion in the on-chain transaction.
Fabric chaincodes can be deployed either as long-running microservices, or as commands that get executed and exited when done.
A chaincode deployment is defined twofold: the executable program, which must be installed on each peer node that requires interaction with the logic or state, and the definition, which must go through the approve/commit lifecycle and is captured on-chain via transactions.
Chaincode supports development in Golang, Node.js and Java. Network interactions with the peer and orderer nodes takes place over a well defined, but very complex, gRPC interface with protobuf as the wire protocol. Using one of the SDKs (supported in Golang, node.js/typescript and Java) is a necessity.
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.
Hyperledger Fabric is free to use. Developed by the Linux Foundation, it is open source and anyone can download it.

Hyperledger Fabric helps members of a network protect personal or proprietary data. For example, if competitors are on a network together, the ledger may represent a transaction but protect the cost associated with that transaction. This maintains an immutable record while business data remains off-chain.
The biggest difference between Hyperledger Fabric and Hyperledger Sawtooth is that Sawtooth allows for permissionless network systems and persmissioned systems. Hyperledger Fabric offers only permissioned network access.
