Every now, into the world of jewelry goes in the technology. It’s the case of the BTC Ring. It is a ring that printed 3D contains a QR code. Each code hides a value in bitcoin, virtual money now popular on the internet. For those who do not follow the evolution of technology, we explain: the bitcoin is an electronic money created in 2009 by an anonymous (hides behind the pseudonym Satoshi Nakamoto). Unlike most traditional currencies (euro, dollar, yen), the bitcoin does not have a central bank: using a database distributed among the nodes of the network that keep track of transactions. In short, it works a bit ‘as programs to download movies and music between a user and another. Transactions exploit encryption to manage the functional aspects such as generating new currency and the attribution of ownership of bitcoin. There are already shops or services where you can pay with this currency. The ring, in short, is like a bank account attached to the finger. Obviously it can be continuously fed. The movie explains how you can use (and is also quite funny). Federico Graglia
