 Gradecoin offers 3 endpoints at [/register](/register), [/block](/block) and [/transaction](/transaction). You can only send GET requests to /block and /transaction without authorization.
 The server is programmed in [RESTful](https://www.service-architecture.com/articles/web-services/representational_state_transfer_rest.html) architecture, there are no `DELETE`, `PUT` or `UPDATE` operations, though.

 # Questions
 ## This all sound complicated!
-- I've drawn inspiration from [actual Bitcoin transactions](https://explorer.bitcoin.com/btc) and [warp](https://github.com/seanmonstar/warp/blob/master/examples/todos.rs). The simplicity of the system is how little interfaces it has.
+- I've drawn inspiration from [actual Bitcoin transactions](https://explorer.bitcoin.com/btc) and [warp](https://github.com/seanmonstar/warp/blob/master/examples/todos.rs). The system has only 3 interfaces. It's simple once you read everything over a couple of times.
 - Don't know where to start? Gradecoin uses RESTful API; simple `curl` commands or even your browser will work! [This website can help as well](https://curl.trillworks.com/).
-- [JWT Debugger](https://jwt.io) and the corresponding [RFC](https://tools.ietf.org/html/rfc7519).

 - Remember that you are absolutely encouraged to grab off-the-shelf implementations for every cryptography primitive you will use. You can start by finding a code snippet to generate a RSA keypair?

 ## I hacked the server!
 That wasn't supposed to happen :( I did not place any intentional vulnerabilities to the system so if you cracked something, it was not intended. Please don't abuse it and let me know so I can patch it.
