  • John shared from Blockchain: Blueprint for a New Economy by Melanie Swan
    With this tool, the blockchain can be used to prove the existence and exact contents of a document or other digital asset at a certain time (a revolutionary capability). Providing timestamped data in an unalterable state while maintaining confidentiality is perfect for a wide range of legal and civic applications.

  • John shared from Blockchain: Blueprint for a New Economy by Melanie Swan
    One broad way of thinking about the use of blockchain concepts is applying them beyond the original context to see ways in which everything is like an economy, a market, and a currency — and equally important, how everything is not like an economy. This is a mindset that requires recognizing the fundamental properties of economics and markets in real-life situations. Blockchain technology helps elucidate that everything we see and experience, every system in life, is economics to some degree: a system for allocating resources.
    Note: Blockchain technology: important because everything is economic to degree-an allocation of resources
  • John shared from Debt - Updated and Expanded: The First 5,000 Years by David Graeber
    After all, we do owe everything we are to others. This is simply true. The language we speak and even think in, our habits and opinions, the kind of food we like to eat, the knowledge that makes our lights switch on and toilets flush, even the style in which we carry out our gestures of defiance and rebellion against social conventions—all of this we learned from other people, most of them long dead. If we were to imagine what we owe them as a debt, it could only be infinite.

    Human nature does not drive us to “truck and barter.” Rather, it ensures that we are always creating symbols—such as money itself. This is how we come to see ourselves in a cosmos surrounded by invisible forces; as in debt to the universe.
    Note: Human nature drives us to create symbols -such as money. #bitcoin #blockchain #euro

    In this sense, the value of a unit of currency is not the measure of the value of an object, but the measure of one’s trust in other human beings.
    Note: Money represents trust in the common knowledge of the value of a unit of trade. #bitcoin #volatility
