We have so far discussed the differences between public and private networks, where it is the network itself, and access to it, which is either public or private. We now turn our attention to the data—both transaction and contract data—inside a given network.
The Ethereum main network can be joined by anyone. Furthermore, all transaction and smart contract data is public, meaning all transactions between a to and from address can be seen by everybody using the network. There is no way to hide these transactions, or the addresses transacting, and as such, there's no way for a user on Ethereum to be truly anonymous. If a way were found to link an address with a real-world identity—either at the present time, or at a point in the future—then the identity of the transacting party would be known.

Overview of this book
The Blockchain is a revolution promising a new world without middlemen. Technically, it is an immutable and tamper-proof distributed ledger of all transactions across a peer-to-peer network. With this book, you will get to grips with the blockchain ecosystem to build real-world projects.
This book will walk you through the process of building multiple blockchain projects with different complexity levels and hurdles. Each project will teach you just enough about the field's leading technologies, Bitcoin, Ethereum, Quorum, and Hyperledger in order to be productive from the outset. As you make your way through the chapters, you will cover the major challenges that are associated with blockchain ecosystems such as scalability, integration, and distributed file management. In the concluding chapters, you’ll learn to build blockchain projects for business, run your ICO, and even create your own cryptocurrency. Blockchain by Example also covers a range of projects such as Bitcoin payment systems, supply chains on Hyperledger, and developing a Tontine Bank Every is using Ethereum.
By the end of this book, you will not only be able to tackle common issues in the blockchain ecosystem, but also design and build reliable and scalable distributed systems.
