Implementing user authentication in Ethereum

Every application requires some sort of authentication and authorization to restrict unauthorized usage. In Ethereum, most of this happens through the externally owned account (EOA) from which the transactions originate. EOAs are generated through strong cryptographic algorithms that are hard to hack unless the hacker has access to the private keys.

In this recipe, you will learn various authentication and authorization methods that can be implemented in your Ethereum DApp.

Getting ready

It is required to have at least a basic knowledge of writing smart contracts and building DApps using Web3JS. Understanding the implementation of a basic DApp is essential to get more out of this...
