Many blockchain use cases require the pinning of on-chain transactions to securely stored documents that cannot be held on-chain, either because they are too large or the information is too sensitive to put into your immutable shared ledger. Kaleido’s Document Exchange was created for these use cases, providing a private store solely for your individual use. We provide the mechanism to generate hashes that uniquely tie an on-chain asset, token, or transaction to off-chain data. If you need an IPFS distributed peer-to-peer file share system where every member of your consortium can access every file, please see our IPFS File Store service.
Kaleido’s Document Exchange allows you to securely forward a copy of a document in your private library to the document store of another participant using our encrypted App2App Messaging Service.
Document Exchange provides APIs for managing the lifecycle of documents* and the ability to connect your private store to an external storage system such as AWS’ S3 or Azure Blob.
The service supports folders to conveniently organize files while allowing you to also address the files by hash regardless of where they are located. Interacting with the service can be done through its graphical user interface, RESTful and socket.io based APIs.
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

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
Kaleido is a Hyperledger Certified Service Provider (HCSP) with a deep expertise in helping enterprises successfully adopt Hyperledger tools.

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 ExpertUse the Document Exchange service to securely upload and transfer files within a Kaleido environment. With blockchains being poorly suited for large payloads and sensitive data such as PII, an ancillary file sharing utility that can exist next to the chain provides immense benefit at both a business and security level. Transactions simply need to reference a file’s hash, rather than dealing with the file contents directly.
Any uploaded or received file can be conveniently organized using intuitive folder structures, and persisted in either Kaleido hosted storage or cloud-delegated and user-controlled services such as AWS S3 Buckets or Azure Blob containers.
All transferred data is deterministically hashed, signed, compressed and asymmetrically encrypted in flight using proven public key infrastructure techniques, offering provable guarantees that only the intended recipient can effectively decrypt the packet.
The service leverages the On-Chain Registry service for address look up and certificate functionality, as well as the Kaleido network’s Kafka backbone for high throughput, fault tolerant reliable delivery and transport. Interaction with service is flexible, with support for the in-console graphical user interface, Kaleido RESTful APIs and socket.io connections for reliable event notification.
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.
