Figured this is something about which I should know and understand. Attended a two- plus hour lecture; am now as confused, only with much more information. A funny aspect to me- it is supposedly non-hackable. At present is considered to be the most democratic of forums, – as a public transaction ledger. However, someone developed it around 2007 and that ‘person’ is not ‘known’. For some reason, listening to all this, it brought up feelings of the ‘big-bang-theory- or the concept of in-the-beginning… As mentioned, lots more information, but still not a clear understanding. If this basic information eludes you, toss in bit coins and art to the mix.
