Both HTTP and WebSocket protocols are built on top of TCP.

I'm well aware of how the protocol stack works.  But there is a difference in how an HTTP client and a TCP client work.  That was the purpose of my question - to determine what approach they were using for the client

<p>In the NXT documentation it says that the Peer protocol uses TCP.  But looking through the code all I see is HTTP.  Does NXT use HTTP or TCP for the Peer protocol?</p>

IMO, NXT is out of topic here.

@JonasSchnelli Community consensus has been that other crypto-currencies are on-topic, see e.g. [A](http://meta.bitcoin.stackexchange.com/q/15/5406), [B](http://meta.bitcoin.stackexchange.com/q/89/5406), [C](http://meta.bitcoin.stackexchange.com/q/335/5406). [tag:NXT] being very similar to Bitcoin in design makes it a decent fit here. Also, it already has almost seventy questions here.

Also see the first paragraph of our [tour] which states "With your help, we're working together to build a library of detailed answers to every question about Cryptocurrencies such as e.g. Bitcoin, Namecoin, Litecoin, Ripple, Zerocoin, Dogecoin, Ethereum, and NXT."

In the NXT documentation it says that the Peer protocol uses TCP. But looking through the code all I see is HTTP. Does NXT use HTTP or TCP for the Peer protocol?
