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 recipe.
For those who are new to this, it is recommended to read through the first three chapters of this book.
How to do it…
- Every DApp is authenticated and authorized by the user's address. The address is the key to accessing a decentralized application built on Ethereum...
