Public/private key signature

[mikessut]

I've been learning about public/private key encryption.

I created a toy model for public private key generation and modified the blockchain to check a digital signature before a transaction can be made.

Not sure if this is of interest to you or not, but thought I'd make you aware of it. (I haven't contributed to many github projects and appologies if this isn't how it is done.)

I believe the reason the automated tests are failing is because the test instantiates a flask server and interacts with it. From what I can tell in the logs, it looks like the automated test fails when trying to create the server on 127.0.0.1:5000. I'm not sure what the correct way to work around this.

FWIW, the tests all pass when run locally.

Rewrote the test to not spin up an actual flask server.

The tests now appear to pass on the automated system.
