Overview of this book

Blockchain technology is a distributed ledger with applications in industries such as finance, government, and media. This Learning Path is your guide to building blockchain networks using Ethereum, JavaScript, and Solidity. You will get started by understanding the technical foundations of blockchain technology, including distributed systems, cryptography and how this digital ledger keeps data secure. Further into the chapters, you’ll gain insights into developing applications using Ethereum and Hyperledger. As you build on your knowledge of Ether security, mining, smart contracts, and Solidity, you’ll learn how to create robust and secure applications that run exactly as programmed without being affected by fraud, censorship, or third-party interference. Toward the concluding chapters, you’ll explore how blockchain solutions can be implemented in applications such as IoT apps, in addition to its use in currencies. This Learning Path also highlights how you can increase blockchain scalability, and discusses the future scope of this fascinating and powerful technology. By the end of this Learning Path, you'll be equipped with the skills you need to tackle pain points encountered in the blockchain life cycle and confidently design and deploy decentralized applications.

Ethereum Wallet


Ethereum Wallet is an Ethereum UI client that lets you create account, send ether, deploy contracts, invoke methods of contracts, and much more.

Ethereum Wallet comes with geth bundled. When you run Ethereum, it tries to find a local geth instance and connects to it, and if it cannot find geth running, it launches its own geth node. Ethereum Wallet communicates with geth using IPC. Geth supports file-based IPC.

Note

If you change the data directory while running geth, you are also changing the IPC file path. So for Ethereum Wallet to find and connect to your geth instance, you need to use the --ipcpath option to specify the IPC file location to its default location so that Ethereum Wallet can find it; otherwise Ethereum Wallet won't be able to find it and will start its own geth instance. To find the default IPC file path, run geth help, and it will show the default path next to the --ipcpath option.
