Cord transaction anchoring scripts (for demonstration purposes)

Requirements

• You are expected to have docker available to run the cord.network locally with developer mode.
• Have yarn installed and ready.
• Any web browser (which supports javascript) to check transactions on the CORD Chain.

How to run the demo code with DOCKER

• Step 1: checkout/clone this repository.

• Step 2: build image locally

sudo docker build -t <docker-image-name> .

• Step 3: run docker image

i) Run demo on sparknet node

sudo docker run <docker-image-name> src/func-test.ts

ii) Run demo on custom node

sudo docker run --env NETWORK_ADDRESS='<network-address>' --env ANCHOR_URI='<anchor-uri>' <docker-image-name> src/func-test.ts

Example : sudo docker run --env NETWORK_ADDRESS='ws://host.docker.internal:9944' --env ANCHOR_URI='//Alice' <docker-image-name> src/func-test.ts

• Here values of NETWORK_ADDRESS and ANCHOR_URI can be changed according to your use case.

How to run the demo code (with local node)

• Step 1: checkout/clone this repository.

• Step 2: install with yarn install once you are inside the repository.

• Step 3: start the CORD Network in the developer mode (In another terminal)

  • docker run --network host dhiway/cord:develop --dev
  • Note that this exposes ports 9933/9944/30333
  • You can watch the events and blocks finalization @ https://apps.cord.network/?rpc=ws%3A%2F%2F127.0.0.1%3A9944#/explorer

• Step 4: run the demo script with npx tsx src/func-test.ts. Understand whats happening by checking the code at src/func-test.ts.

How to run the demo code (with staging network)

• Step 1: checkout/clone this repository.

• Step 2: install with yarn install once you are inside the repository.

• Step 3: You can watch the events and blocks finalization @ https://apps.cord.network/?rpc=wss%3A%2F%2Fstaging.cord.network#/explorer

• Step 4: Open the demo file you want to run (eg., src/func-test.ts) and change ws://127.0.0.1:9944 to wss://staging.cord.network. Save the file.

• Step 5: run the demo script with npx tsx src/func-test.ts. Understand whats happening by checking the code at src/func-test.ts.

• Step 6: run the VC (Verifiable Credential) demo script by running npx tsx src/func-test.ts.

  • NOTE: The VerifiableCredential is a required form of output if your application wants to interact with other applications. If one needs to have complete eco-system in their control, just the stream format of CORD SDK is good enough.

What next from here?

• Understand the methods exposed from SDK by refering how func-test.ts and network-score-test.ts files are structured.

• You can refer our white paper for multiple usecases through https://cord.network

• To build on CORD chain, visit cord project repo.

  • SDK development work is happening at CORD.js repository
  • SUBQL (Substrate's GraphQL update, which can help in organizing events and extrinsics happening on CORD chain) - Repository
