Digital Signatures

[sambux1]

We will need a digital signature scheme to verify and prove the authenticity of messages, such as those which add data to the blockchain.

I am currently doing some background research on this topic. I will type up some notes on how digital signatures work and how we can use them in our system, and I will upload this into the repo.

After that, we can decide on the best approach and begin implementing. It's more important to have a bad implementation that we can improve on than wait forever to try to make it perfect on the first try.
