The problem with Bitcoins, as I understand it (I don’t own any, and have never used them to buy anything) is that transactions can take anywhere from 10 minutes to hours, depending on how busy the network is. It’s also fairly expensive to use, especially for small transactions.
Ethereum, on the other hand, takes 12 seconds to transact and is much cheaper, but it’s also much more than a currency: it’s a platform for something called decentralised applications (dApps) that run on peer to peer computer networks and are designed to disintermediate all kinds of transactions that currently require banks, stock exchanges and the legal system itself.
Everyone is now flocking to the Ethereum side of the boat, it seems. In March, 116 organisations formed Enterprise Ethereum Alliance, including Samsung, Microsoft, Intel, JP Morgan, Deloitte, Accenture, Banco Santander, ING and National Bank of Canada.
