The Future of Crypto Networks and Block Chain?

Ike: crypto networks and block chain can be a very powerful tool that will allow maybe a shadow economy or social network to evolve. Big coin isn't a currency, so the whole thing isn't real but then i hear, this is a technology that's going to change the world. But what i don't understand is, what is the technology? It's just contracts? Don't we have technology that tracts contracts? Ike: If any criminals are listening, do better, please come use the coin i'll send you.
