Hyperledger Cactus

This project is an Incubation Hyperledger project. For more information on the history of this project see the Cactus wiki page. Information on what Active entails can be found in the Hyperledger Project Lifecycle document.

Hyperledger Cactus aims to provide Decentralized, Secure and Adaptable Integration between Blockchain Networks. Hyperledger Cactus is currently undergoing a major refactoring effort to enable the desired to-be architecture which will enable plug-in based collaborative development to increase the breadth of use cases & Ledgers supported.

Scope of Project

As blockchain technology proliferates, blockchain integration will become an increasingly important topic in the broader blockchain ecosystem. For instance, people might want to trade between multiple different blockchains that are run on different platforms. Hyperledger Cactus is a web application system designed to allow users to securely integrate different blockchains. It includes a set of libraries, data models, and SDK to accelerate development of an integrated services application. Our goal is to deliver a system that allows users of our code to securely conduct transactions between all of the most commonly used blockchains.

Run the Examples

Supply Chain Example

1. Ensure a working installation of Docker is present on your machine.
2. Run the following command to pull up the container that will run the example application and the test ledgers as well:

   docker run \
     --rm \
     --privileged \
     -p 3000:3000 \
     -p 3100:3100 \
     -p 3200:3200 \
     -p 4000:4000 \
     -p 4100:4100 \
     -p 4200:4200 \
     ghcr.io/hyperledger/cactus-example-supply-chain-app:2021-09-08--docs-1312

3. Wait for the output to show the message INFO (api-server): Cactus Cockpit reachable http://0.0.0.0:3100
4. Visit http://localhost:3100 in a web browser with Javascript enabled
5. Use the graphical user interface to create data on both ledgers and observe that a consistent view of the data from different ledgers is provided.

Once the last command has finished executing, open link printed on the console with a web browser of your choice
