Title: Understanding the Bitcoin Protocol. Seriously
Abstract:
In the last six years, Bitcoin has obtained a good deal of attention, reaching in May 2019 a market capitalization of more than one hundred and fifty billion (US) dollars and a daily trading volume of hundreds of millions of dollars. Although Bitcoin is considered mostly as a financial asset, the protocol published in 2008 by the anonymous Satoshi Nakamoto goes far beyond: it achieves consensus in an open, decentralized and trust-less network. In this tutorial, we will discuss in detail how this consensus is achieved, from the underlying cryptography to the specifics of the protocol and the concept of proof of work. We will also discuss the incentives of the different actors in the Bitcoin network, and how these incentives complement the underlying cryptography to allegedly enforce the security of the digital currency.
