| Blockchain: hype or the future? Posted: 21 Dec 2017 08:05 AM PST Hi all, The recent news of the rise in price of Bitcoin and other cryptocurrencies has only further increased the hype around blockchain technology. I keep hearing statements about startups and governments and banks investing in the technology, but I am quite confused about this. How can a company make money by using a blockchain? Isn't the whole point that it should be decentralised? How can it be used for, e.g. land registry if a physical house burns down (does this not need an authority to tell everyone what happens in reality)? How could it be used to replace e.g. Paypal? Some quirks of a blockchain seem downright bad for these applications: e.g. append-only, much slower. I guess my questions are: (1) How can a company make mnoey with blockchain technology, and are there any out there today? and (2) Why would a company or government use a blockchain instead of a database?
