DIP1
Final Year Project 2022 at HKUST
The smart contract of local chain and global chain are developed based on asset-transfer-basic smart contract from fabric-samples of Hyperledger Fabric.
The backend for local chain and backend for global chain are based on application from asset-transfer-basic.
The folder of tlsCert at local and tlsCert at global stores a self-signed certificates for testing purpose and is gitignored.
The backend for the local chain is a backend for the Admin.
To install all executables, please refers to the Hyperledger Fabric Official Website test network tutorial to install.
dependencies are:
docker-compose >=1.29
golang >=1.16.13
config mysql database by setting the config file in applications.
# cd to current directory
curl -sSL https://bit.ly/2ysbOFE | bash -s -- -s
To launch two peers and deploy local chain and global chain on these peers, run the following
cd test-network
./deploy.sh
In this repo, 2 peers are launched. 2 channels are created. The mychannel is the local chain. The globalchannel is the global chain. Both channels run on two same peers.
To launch two backend servers, run the following
cd asset-transfer-basic/application-go
go run main.go
cd asset-transfer-basic/application-go-gloabl
go run main.go
Two channels should run and not interrupt each other.
More experiments on multi-host for Hyperledger Fabric can be found in the following:
The Fabric test network in the samples repository provides a Docker Compose based test network with two Organization peers and an ordering service node. You can use it on your local machine to run the samples listed below. You can also use it to deploy and test your own Fabric chaincodes and applications. To get started, see the
The asset transfer series provides a series of sample smart contracts and applications to demonstrate how to store and transfer assets using Hyperledger Fabric. Each sample and associated tutorial in the series demonstrates a different core capability in Hyperledger Fabric. The Basic sample provides an introduction on how to write smart contracts and how to interact with a Fabric network using the Fabric SDKs. The Ledger queries, Private data, and State-based endorsement samples demonstrate these additional capabilities. Finally, the Secured agreement sample demonstrates how to bring all the capabilities together to securely transfer an asset in a more realistic transfer scenario.
