A Cryptocurrency (in Go!)

I made it so nodes sync the blockchain on startup. Also, they exchange their public keys when they connect, I’ll use this to implement de-duplication of connections later! (I ran into a bug when implementing peer discovery where a node would just repeatedly connect to itself)

I know the demo isn’t very exciting but it shows the nodes connecting, exchanging keys, and syncing the blockchain.

Next is peer discovery!

Oh, I should also make the difficulty change dynamically and probably clean up the code a bit and maybe actually make it so transactions can be created through the cli, that seems important.
