All the compiled contracts will generate a JSON file under build / contracts and open the generated hello_ Falco. JSON file, you can see theabi,bytecodeAnd other information, which will be used in the future. Deploy contracts to Ganache. to configuretruffle.jsTo deploy our contract on Ethereum’s Ropsten blockchain we will need access to an Ethereum Ropsten node. For that, we could use pretty much any Ethereum client such as Geth or OpenEthereum (fka Parity). Since that is a bit too involved for deploying a single contract, we'll just grab a free trial Ropsten endpoint from QuickNode to make this.By the end, you’ll have started a local private Ethereum blockchain, connected two different nodes as peers, written and compiled a smart contract, and have a web interface that allows users to ask questions, deploy the questions on the blockchain, and then lets the users answer.
