The aim of this book is to give you a deep insight into the intricacies of how ethereum works and how to develop your first decentralized application from scratch on the ethereum blockchain. With the aid of vivid examples, you can navigate smoothly and gain smooth understanding. The book also include how ethereum keen agreement works and proper understanding of how to develop your first decentralized application from scratch on the ethereum blockchain. Have you asked yourself questions such as... ¿ What is ethereum? ¿ How is it different to bitcoin? ¿ How can i use ethereum? ¿ How is ether mined? ¿ What are smart contracts? ¿ What does the future hold for ethereum? Mining is the process of sorting through blocks in the blockchain, and approving of transactions. In an earlier chapter, we described how it's essentially the act of solving difficult code puzzles. Blocks in ethereum don't actually represent currency, they represent anything of value, so they take the form of smart contracts. In normal systems, there's one central authority that does this work, but because ethereum is a decentralized platform, it's up to all the nodes to make sure the record-keeping is accurate.
