Don Tapscott and his son Alex have been wandering the planet this year, touting something called Blockchain as the future of everything.
I was skeptical, but now I understand. I hope when you finish reading this that you will as well.
Blockchain is, at heart, an encryption algorithm. A successful encryption and decryption leaves a digital “token” you and your trading partner agree to put a value on. This is “crypto currency.” Blockchain advocates prefer the term “trust units.”
The best-known implementation of blockchain is Bitcoin. Bitcoin is a marketplace for tokens that are created through decryption. There are only 21 million available answers to the Bitcoin puzzle, thus the “money supply” of Bitcoin is fixed.
