  • 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.
    Note: The blockchain can be used to prove the existence and exact contents of a document at a certain time
  • 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.

  • John shared from Debt - Updated and Expanded: The First 5,000 Years by David Graeber
    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
  • John shared from Debt - Updated and Expanded: The First 5,000 Years by David Graeber
    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
  • John shared from Debt - Updated and Expanded: The First 5,000 Years by David Graeber
    Credit Theorists insisted that money is not a commodity but an accounting tool.
    Note: The essence of money is the ledger, not the bills. #bitcoin #blockchain
  • John shared from The Age of Cryptocurrency: How Bitcoin and Digital Money Are Challenging the Global Economic Order by Paul Vigna, Michael J. Casey
    “Now the crowd has their own business model,” says Jeremiah Owyang, the founder of the consulting service Crowd Companies. Offering a broad definition of the collaborative economy that encompasses everything from barter to lending to gifting, Owyang suggests that the entire human populace is now taking charge of the means of production and changing the rules of the game. “They’re making their own freaking currencies, for God’s sake,” Owyang adds emphatically.
    Note: "...the entire human populace is now taking charge of the means of production..." #crowdcapitalism
  • John shared from Your Brain at Work by David Rock
    Whereas the issues listed here, while being important, are also a bit intangible; thus they take more effort to consider. We all often think about what’s easy to think about, rather than what’s right to think about.
    Note: "We all often think about what's easy to think about, rather than...what's right to think about."

    Subtle internal changes, which happen within a fraction of a second and may not be noticeable to the outside world, can sometimes change everything.

  • John shared from Get Big Things Done: The Power of Connectional Intelligence by Erica Dhawan, Saj-nicole Joni
    What makes the Ushahidi.com platform so powerful is that it can integrate information sent by anyone connected by almost any means. Add to Ushahidi.com, the connectional intelligence of people like Patrick Meier, and we see how combining disparate individuals, groups and information can and does indeed save lives. Courage builds on courage. This way of combining and forging connections is becoming a go-to template for crisis management around the world.
    Note: Courage builds on courage. #ushahidi
