+<p>Blockchains are incredibly simple yet can appear very complicated, we will see how they work and practice programming <em>production</em> cryptography code.</p>
+<p>This server is the sandbox for the PA1, it's currently running the Gradecoin application. Gradecoin is the faux currency we will use to simulate a blockchain network. At the end of the simulation, the amount of Gradecoin you hold will be your PA1 grade.</p>
+<p><strong>A quick summary</strong>: authenticate yourself to the system using public key encryption.
+Craft <a href="http://localhost:8080/transaction-docs/">Transaction</a> proposals and tag them using <a href="http://localhost:8080/jwt/">JWTs</a>.
+When there are enough transactions then you can propose <a href="http://localhost:8080/block-docs/">Blocks</a> in the same way.
+Blocks need to be <em>mined</em> beforehand using Proof-of-work, or brute force.</p>
+<p>Gradecoin offers 3 endpoints at <a href="/register">/register</a>, <a href="/block">/block</a> and <a href="/transaction">/transaction</a>. You can only send GET requests to /block and /transaction without authorization.
+The server is programmed in <a href="https://www.service-architecture.com/articles/web-services/representational_state_transfer_rest.html">RESTful</a> architecture, there are no <code>DELETE</code>, <code>PUT</code> or <code>UPDATE</code> operations, though.</p>
+<p>Gradecoin uses a Proof-of-work block accepting mechanism. It uses single round <a href="https://www.blake2.net/">Blake2s</a> hashing which produces 256-bit (64 hexadecimal characters) output. The <a href="https://wiki.bitcoinsv.io/index.php/Target">target</a> hash is <em>24 bits</em> or <em>6 hexadecimal characters</em> of 0. During testing, I could mine a block on average around 2-7 minutes.</p>

+<p>But if nobody has any Gradecoin then how do we have transactions?</p>

+<p>There is a bank! Their public key is <code>31415926535897932384626433832795028841971693993751058209749445923</code> and they have some amount of Gradecoin preloaded. It's also the only account that you can send transactions requests <em>to</em> yourself.</p>

+<p>The first transactions of a block is called the <code>coinbase</code>. They are the <strong>author</strong> of the block proposal and if the block is accepted then they get compensated for their efforts with some Gradecoin.</p>
