Another problem inherited from Bitcoin is that Ethereum is slow. It is many magnitudes slower than other platforms that host transaction data, for instance a traditional database. For example, it takes an average of 10 minutes to build a new record for Bitcoin. As a rule of thumb, after waiting for six new blocks to be built, a transaction is considered to be finalized (the same as a commitment in a database). This means that, on average, a requester will wait for one hour to see a request completed. In Ethereum, the average time for miners to build a block is 17 seconds and it is recommended you wait for 12 blocks before a transaction is confirmed. This is 12 * 17 = 204 seconds, or 3.4 minutes' waiting time for a user. Here, waiting for a few subsequent blocks to be built before confirming a transaction is useful. At any point, Ethereum can have competing...

Overview of this book
Blockchain is a technology that powers the development of decentralized applications.This technology allows the construction of a network with no single control that enables participants to make contributions to and receive benefits from the network directly.
This book will give you a thorough overview of blockchain and explain how a blockchain works.You will begin by going through various blockchain consensus mechanisms and cryptographic hash functions. You will then learn the fundamentals of programming in Solidity – the defacto language for developing decentralize, applications in Ethereum. After that, you will set up an Ethereum development environment and develop, package, build, and test campaign-decentralized applications.The book also shows you how to set up Hyperledger composer tools, analyze business scenarios, design business models, and write a chain code. Finally, you will get a glimpse of how blockchain is actually used in different real-world domains.
By the end of this guide, you will be comfortable working with basic blockchain frameworks, and develop secure, decentralized applications in a hassle-free manner.
