Hands-On Blockchain for Python Developers

Deploying a smart contract to Ganache

So how do you deploy this smart contract to the Ethereum blockchain? There are few ways to do this, but let’s employ a familiar way using Truffle:

1. Create a directory and initialize it with truffle init as follows:

$ mkdir hello_project$ cd hello_project$ truffle init

2. Just as you did in the previous chapter, set truffle-config.js as the following:

module.exports = {  networks: {    "development": {      network_id: 5777,      host: "localhost",      port: 7545    },  }};

3. Create a build directory, as follows:

$ mkdir -p build/contracts$ cd build/contracts

4. Then create a Hello.json file there, as follows:

{  "abi":  "bytecode":}

5. Then fill the abi field with abi or json output from the compilation process, and fill the
