Crypto currency Ecosystem

Cryptocurrency Protocols Are Like Onions… One common design philosophy among many cryptocurrency 2.0 protocols is the idea that, just like the internet, cryptocurrency design would work best if protocols split off into different layers. Under this strain of thought, Bitcoin is to be thought of as a sort of TCP/IP of the cryptocurrency ecosystem, and other next-generation protocols can be built on top of Bitcoin much like we have SMTP for email, HTTP for webpages and XMPP for chat all on top of TCP as a common underlying data layer.” – Vitalik Buterin
