Hi, Neil, you've written a clear explanation on the blockchain, and it's very helpful for a short talk that I'm preparing to give tomorrow afternoon. I read your book, "The Game", one day when shopping in a bookstore. I read it cover to cover in that bookstore! You're a great writer and I look forward to reading more of your writings. It's great that you're covering blockchain, too. If you ever want to seek the views of a diverse, international team of blockchain-focused lawyers, feel free to get in touch.
