In addition to what I blogged about yesterday, about the European Central Bank wanting more control over Bitcoin, Andreas Antonopoulos talks about Hard Promises and Soft Promises, about Autonomy instead of Authority. I am definitely with him. Bitcoin's Blockchain feature of unalterable record of all transactions is not a weakness. It is a strength. Do not change it. Being able to change the details of transactions is like being able to change how history is written in textbooks.
