This project is an _Incubation_ Hyperledger project. For more information on the history of this project see the [Cactus wiki page](https://wiki.hyperledger.org/display/cactus). Information on what _Active_ entails can be found in

the [Hyperledger Project Incubation Exit Criteria document](https://wiki.hyperledger.org/display/TSC/Project+Incubation+Exit+Criteria).

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](https://docs.docker.com/desktop/) 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:

    ```sh

    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:2024-03-08--pr-3059-1

    ```

3. Wait for the output to show the message `INFO (supply-chain-app): SupplyChainApp Web GUI - reachable at: http://127.0.0.1:3200`

4. Token generated by the application is displayed below

5. Visit http://127.0.0.1:3200 in a web browser with Javascript enabled and insert the token when prompted

6. 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

## Inclusive Language Statement

These guiding principles are very important to the maintainers and therefore

we respectfully ask all contributors to abide by them as well:

- Consider that users who will read the docs are from different backgrounds and

cultures and that they have different preferences.

- Avoid potential offensive terms and, for instance, prefer "allow list and

deny list" to "white list and black list".

- We believe that we all have a role to play to improve our world, and even if

writing inclusive documentation might not look like a huge improvement, it's a

first step in the right direction.

- We suggest to refer to

[Microsoft bias free writing guidelines](https://docs.microsoft.com/en-us/style-guide/bias-free-communication)

and

[Google inclusive doc writing guide](https://developers.google.com/style/inclusive-documentation)

as starting points.
