This book would not have been possible without the support of a large number of people.
Along this journey, and although I may not agree with all of them all the time, I have been influenced by people with a wide range of perspectives. I am grateful to them for sharing their knowledge and opinions with the world, online for free. I have particularly enjoyed content from260 Gavin Andresen, Andreas Antonopoulos, Richard Gendal Brown, Vitalik Buterin, Gideon Greenspan, Ian Grigg, Dave Hudson, Izabella Kaminska, Rusty Russell, Tim Swanson261, Robert Sams, Emin Gun Sirer, and Angela Walch.
Other friends have been generous with their time and expertise: Drew Graham and Varun Mittal have been at the end of Whatsapp, responding quickly when I have needed help or inspiration, and industry experts in various crypto-related chat rooms have consistently made themselves instantly available to contribute with a quick insult or flippant comment—thank you.
I am immensely grateful to the team at Mango Publishing for their work in making this book a reality: Ashley, Hannah, Mario, Michelle, Natasha, Roberto, Chris, and the others working behind the scenes. Thank you, Hugo, for taking a risk and having confidence in me.
Sarah, thank you for looking after our children while I sat for many hours writing in coffee shops, and for occasionally reminding me of my real-life responsibilities as husband and father too.
Finally, I’d like to thank my father Kevin, who spent many hours diligently editing my drafts despite having minimal prior interest or experience in cryptocurrencies! Papa, you are now a Bitcoin expert.
It takes a decentralised village to raise a book on cryptocurrencies.
