This is the genesis of a new crypto universe. It's hugely hyped, and a lot of it is clearly BS. But underlying the hype and hysteria there's a kernel of a new paradigm emerging.
Crypto applications promise to provide disintermediation on a scale not seen before. Direct peer to peer transactions, conducted transparently, without a need to verify trust and happening simultaneously anywhere in the world.
Not only that but smart contracts bring with them the potential to do stuff that simply is not possible right now. For example, providing instant conditional transactions (if my fave rental car is available book it, otherwise search for another solution, but only from these sources at this price) etc etc etc. We don't know what this means, but it could be a revolution. Or not. :)
