BitBadges Blockchian

bitbadgeschain is a blockchain built using Cosmos SDK and Tendermint and created with Ignite CLI. BitBadges offers an open-source, community-driven suite of tools focused on cross-chain issuance of digital tokens (badges). This blockchain is the core of the BitBadges ecosystem.

See the BitBadges documentation to learn about BitBadges and the BitBadges blockchain.

See the Cosmos SDK Docs to learn about the Cosmos SDK and Tendermint. This repository follows the Cosmos SDK's directory structure.

Acknowledgements

We want to acknowledge the Evmos project for maintaining and open-sourcing their software, which BitBadges was built upon.

Building with Makefile

The following instructions are for Ubuntu 23.10. If you are using a different operating system, you may need to modify the commands.

If you do not have the following dependencies installed, you will need to install them before you can build the blockchain.

sudo apt-get install git curl make build-essential gcc

To build the BitBadges blockchain from source, run the following:

snap install go --classic # Install Go 1.21

To build the BitBadges blockchain from source, run the following:

make build-all
# OR
make build-linux/amd64
make build-darwin/amd64
make build-linux/arm64

For building linux/arm64, you will need to have a cross-compilation toolchain installed. You can install it with the following command:

sudo apt-get install gcc-aarch64-linux-gnu

For building darwin/amd64, you will need to have the o64-clang cross-compilation toolchain installed. We refer you to the https://github.com/tpoechtrager/osxcross project for more information.

Building / Serving With Ignite CLI

This blockchain was also built using the Ignite CLI. To build and serve the blockchain, download the Ignite CLI from the Ignite CLI website.

Then, run the following commands to build and serve the blockchain:

ignite chain init --skip-proto
ignite chain build --skip-proto
ignite chain serve --skip-proto

You will have to use the --skip-proto flag because we manually correct a query file to fix a small bug in the generated code.

Your blockchain in development can be configured with config.yml. To learn more, see the Ignite CLI docs.

Web Frontend

See the BitBadges documentation and BitBadges website for more information.

Release

To release a new version of the blockchain, create and push a new tag with v prefix. A new draft release with the configured targets will be created.

git tag v0.1
git push origin v0.1

After a draft release is created, make your final changes from the release page and publish it.

Development

The BitBadges blockchain is open-source and community-driven. We welcome contributions from the community. To contribute, fork this repository and submit a pull request.

Couple of development notes:

• The x directory contains the modules of the blockchain. Each module is a separate directory.
• The proto directory contains the protobuf files for the modules. These files are used to generate the Go code for the modules. This has typically been done with ignite generate proto-go.
• The chain-handlers directory contains the handlers for the blockchain. These handlers are used to handle the signature logic for each respective blockchain that is supported. Ethereum uses EIP712 signatures. Solana and Bitcoin use a JSON schema with everything alphabetically sorted. Cosmos uses typical Cosmos signatures. Learn more on the BitBadges documentation and via bitbadgesjs.
