• pkg/: 3rd-party helpers.
• scripts/: Test environment setup.
• wallet/: Wallet interface implementations.

Development Setup

If you want to locally develop with this project:

1. Setup the fabric-samples test environment and add its directory as FABRIC_SAMPLES_DIR to your path.

curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/v2.4.6/scripts/bootstrap.sh | bash -s
FABRIC_SAMPLES_DIR=$(pwd)/fabric-samples/

2. Clone this repo.

git clone https://github.com/perun-network/perun-fabric.git
cd perun-fabric

3. Start the test chain and deploy the chaincode. This step needs a working Docker instance running in the background.

./scripts/deployCC.sh

4. Run the tests. This step needs a working Go distribution, see go.mod for the required version. Always ensure that FABRIC_SAMPLES_DIR is set.

go test ./... -p 1

Further, you can shut down the test environment.

./scripts/network.sh down

Or start the test environment without chaincode deployment.

./scripts/network.sh up
