It’s a distributed virtual computer that anyone can securely run programs on and trust their results. Applications on Ethereum require zero infrastructure and are immune to downtime. The code that runs an Ethereum application is verifiable. Users can know that the program they are interacting with does exactly what it claims to do.
Ethereum includes a digital currency called ether. Ether has a lot in common with the famous digital currency Bitcoin. Both are a purely digital store of value and means of exchange that cannot be counterfeited. Both are implemented so that no one can manipulate the currency supply. Both can be transferred around the world, like email, and in a very final way, like cash. Both have value today because users expect them to have value tomorrow, and because they can do things traditional money can’t.
So, Ethereum is both a digital currency and a programming language. But it is the combination of these ingredients that make it special.
