Web3 Educhain

EduChain is based on the parachain template.

This template is automatically updated after releases in the main Polkadot SDK monorepo.

Parachain developed and maintained by Technical Education team at Web3 Foundation. To be used for creating tutorials on a wide range of Polkadot SDK enabled features.

Getting Started

• 🦀 The repository is using the Rust language.

• 👉 Check the Rust installation instructions for your system.

• 🛠️ Depending on your operating system and Rust version, there might be additional packages required to compile this repository - please take note of the Rust compiler output.

Build

🔨 Use the following command to build the node without launching it:

cargo build --release

🐳 Alternatively, build the docker image:

docker build . -t polkadot-sdk-parachain-template

Generate Artifacts for Deployment

We use pop! CLI to generate the artifacts:

pop build spec \
  --output ./artifacts/latest_raw_chain_spec.json \
  --chain ./artifacts/latest_plain_chain_spec.json \
  --genesis-state \
  --genesis-code \
  --type live

If you make runtime changes and want to generate a new chainspec + the patch, use the deploy/gen_base_chain_spec.sh script, then run the above to generate the artifacts. Keep in mind you may have to change some details, such as the name, protocol ID, etc to its original state:

{
  "name": "Educhain Paseo",
  "id": "live",
  "chainType": "Live",
  "bootNodes": [],
  "telemetryEndpoints": null,
  "protocolId": "educhain-paseo-live",
  "para_id": 4883,
  "relay_chain": "paseo",
  "properties": {
    "tokenDecimals": 10,
    "tokenSymbol": "PAS"
  },
  ...
}

Local Development Chain

This project uses pop! CLI to run a complete local setup:

pop up network -f ./pop-paseo-testnet-toml

Connect with the Polkadot-JS Apps Front-End

• 🌐 You can interact with your local node using the hosted version of the Polkadot/Substrate Portal: relay chain and parachain.

Please note that if running locally, you must use the URLs given in the terminal when running pop (or Zombienet).

• 🪐 A hosted version is also available on IPFS.

• 🧑‍🔧 You can also find the source code and instructions for hosting your own instance in the polkadot-js/apps repository.
