Document Exchange

Store, Manage, and Share Information from Your Own Private Document Exchange

With Kaleido's document exchange you can easily pin on-chain transactions to securely store documents that cannot be held on-chain.

What it

Document Exchange


What it is

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.

Easily Share Documents Using Secure App2App Messaging

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.

Conveniently Connect to Your External Storage

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.

Robust and Developer-friendly

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 based APIs.

Hyperledger Fabric at a glance


Built for permissioned networks


Data isolation and strict governance enabled by Hyperledger Fabric certificate authority

Transaction Flow

Unique Execute-Order-Commit endorsement model where transactions are initially executed on a set of peers while ordering service handles packaging and delivery.

Consensus Algorithms

Consensus protocols such as Solo, Practical Byzantine Fault Tolerance (PBFT), Raft or Kafka (to be able to use several ordering nodes) can be plugged in.

Smart Contract Language

Go, Java, Node.js

What Is Hyperledger Fabric?

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.

Benefits of Hyperledger Fabric

Hyperledger Fabric is an open source project designed to handle enterprise-grade use cases. A key differentiator is its quick transaction throughput. Developers choose to build applications with Hyperledger Fabric because of its modularity. It’s flexible, allowing for more innovation and optimization regardless of industry. Other benefits include scalability and security, key pillars of any enterprise application.

Better performance

One click is all it takes to deploy Ethereum nodes in the Unlike other private networks that require every peer to execute transactions and maintain a full ledger, Hyperledger Fabric allows for more delineation of roles among members

Open source

Part of the Hyperledger project of the Linux Foundation, the architecture of Hyperledger Fabric allows for scale and performance

Permissioned network

Developers can build subnets or channels to keep certain transactions and data private while maintaining a shared ledger

How it works

How it Works

Use 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 connections for reliable event notification.

Web3 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.


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.
