How do you deploy a smart contract on Ethereum private network?

Install the requisite software packages to run a private Ethereum blockchain on a Mac. Run a private blockchain in a test environment, and “mine” dummy “ether” and “gas” ( to run smart contracts). Create a “Hello World” smart contract in Solidity, compile it using Truffle and deploy it to the private Ethereum network.

How does smart contract deployment work?

Contract deployment is a special Ethereum transaction sent to the address 0. The deployment has the side effects of creating bytecode at a specific address (i.e, it creates a smart contract account). Contracts are deployed at predictable addresses based on the address and nonce of the account creating the contract.
