Most interesting protocols

[highperspective]

What protocols do you find most interesting? What are the usecases of these protocols, and why do you see a big potential?
Could be nice with some brainstorming!

Not sure what kind of protocols, do you mean applications? Maybe online lotteries or digital signatures will do?

I think most people here will be interested in the bitcoin protocol 

I'm guessing you're asking about application / second layers on top of the btc network?

What do you refer to when you say "protocol"? Other cryptocurrencies? Because their not really a "coin" but a "network".

To answer your question, I find Monero to be the most interesting as it attempts to fix Bitcoin's problem with fungibility. As a currency, Bitcoin can be traced back to you by doing blockchain analysis. This is not a problem if you do not mind other people seeing all your transactions in the blockchain. But some of the users do mind. We need our privacy and Monero is developing something to get some of it back.

It's too bad I did not invest in it when it was $30 - $40 though. I thought it was overvalued.
