In June of this year, Facebook unveiled Libra, global currency that draws on the architecture of Bitcoin. The quest for new forms of money hasn’t gone away.

As a direct response to the crisis, in October, 2008, Satoshi Nakamoto, whoever he or she or they might be, published the white paper that outlined the idea of Bitcoin, a new form of money based on nothing but the power of cryptography. The credit crunch in 2008 triggered a panic when people throughout the financial system wondered whether the numbers on balance sheets meant what they were supposed to mean.

What they take is a certain fine white bast or skin which lies between the wood of the tree and the thick outer bark, and this they make into something resembling sheets of paper, but black.
