  • Docker-compose (recommend: v1.14.0 or greater)
  • node.js v12 (recommend: v12.20.2 or greater)
  • The ports 5034, 5040, 5050 are available (If they are already used, the following processes can be done by changing the port number setting)

Boot method

  1. Before booting, please modify the following information for your environment
    • applicationHostInfo.hostName (IP address of the host on the Location header) on /packages/config/default.json
  2. (Optional) Please modify the following information for your environment if necessary. This procedure should only be performed by users who cannot use port 5034.
    • applicationHostInfo.hostPort (The port number of Routing-interface http server, the default is 5034) on /packages/config/default.json
  3. Go to the following directory:
    • cd cactus/examples/cartrade/
  4. Start ledgers:
    • ./script-start-ledgers.sh
  5. Build validators, packages, and the cartrade app:
    • ./script-build-all.sh
  6. Start validators and the cartrade app
    • Please open three consoles and execute the following:.
    • Start the validator for Fabric on the first console: ./script-start-validator-fabric.sh
    • Start the validator for Ethereum on the second console: ./script-start-validator-ethereum.sh
    • Start the cartrade app on the third console: ./script-start-cartrade.sh

How to use this application

  1. (Optional) Check the balance on Ethereum and the fabcar ownership on Fabric using the following script
    • ./script-build-get-app.sh (only the first time)
    • ./script-get-app.sh
    • The result is as the following: 
       [process] Execute an app for getting Balance on Ethereum
 The balance of fromAccount:
 BigNumber { s: 1, e: 4, c: [ 100000 ] }
 The balance of toAccount:
 BigNumber { s: 1, e: 1, c: [ 0 ] }
 [process] Execute an app for getting ownership on Fabcar
 ##queryCar Params: CAR1
 Transaction has been evaluated, result is: {"colour":"red","make":"Ford","model":"Mustang","owner":"Brad"}
  2. Run the transaction execution using the following script
    • ./script-post-cartrade-sample.sh
    • After this, the transactions are executed by order. When the following log appears on the above third console (the console of ./script-start-cartrade.sh), the transactions are completed. 
       [INFO] BusinessLogicCartrade - ##INFO: completed cartrade, businessLogicID: guks32pf, tradeID: *******-001
  3. (Optional) Check the balance on Ethereum and the fabcar ownership on Fabric using the following script
    • ./script-get-app.sh
    • The result is as the following. In the following case, 50 coins from fromAccount was transferred to toAccount, and the car ownership ("owner") was transferred. 
       [process] Execute an app for getting Balance on Ethereum
 The balance of fromAccount:
 BigNumber { s: 1, e: 4, c: [ 99950 ] }
 The balance of toAccount:
 BigNumber { s: 1, e: 1, c: [ 50 ] }
 [process] Execute an app for getting ownership on Fabcar
 ##queryCar Params: CAR1
 Transaction has been evaluated, result is: {"colour":"red","make":"Ford","model":"Mustang","owner":"Cathy"}
