There's a lot of people who are not hot girls on Twitter who are really excited about blockchain as a technology. The idea is that instead of having to trust the single holder of record, for example, Visa saying, yes, we show that you made this transaction, everybody gets to audit all of the transactions when they happen on chain. Unfortunately, theBlockchain technology as it exists today is largely way too slow and way too limited in order to accommodate all the transactions that people are claiming it's useful for.
