Today trivial and obvious patent of the day comes from (as they always do, of course) the USA https://t.co/tzURTHPJ54 <- '“Visa doesn't give much away about what a "central entity computer" would be' oh what do you call those things I can't remember the word databox or something?
RT @CoinDesk: .@Visa looks to be laying the groundwork for a future in which fiat currencies, like the U.S. dollar, could be easily turned into a central bank digital currency and recorded on a blockchain.
I’m really excited about digital currencies but digital currencies do not need blockchain. They’re centralized currencies and technology is used to facilitate and streamline transactions. A central bank does not need blockchain or distributed cryptocurrencies.
