Ethereum Wallets and Smart Contracts

Abstract

In Chapter 1 , I introduced Ethereum when I covered bitcoin, altcoins, and different consensus mechanisms. Specifically, I covered Ethereum’s PoW consensus and how utilizing Ethereum enables developers to create their own smart contracts and tokens. I mentioned that the Ethereum tokens can be generated as Ethereum requests for comment (ERCs) such as ERC-20, ERC-223, or ERC-777. In Chapter 3 , you created your own blockchain, and I covered bitcoin wallets and transactions.
