<p>A block that was proposed to commit Transactions in <code>transaction_list</code> to the
ledger with a nonce that made <code>hash</code> valid; 6 zeroes at the left hand side of the
hash (24 bytes).</p>
<p>We are <em>mining</em> using <a href="https://www.blake2.net/">blake2s</a> algorithm, which produces 256 bit hashes. Hash/second is roughly 20x10^3 on my machine, a new block can be mined in around 4-6 minutes.</p>
<h1 id="requests">Requests</h1>
<h2 id="get">GET</h2>
<p>A HTTP <code>GET</code> request to <a href="/block">/block</a> endpoint will return the latest mined block.</p>
<h2 id="post">POST</h2>
<p>A HTTP <code>POST</code> request with Authorization using JWT will allow you to propose your own blocks.</p>
<h1 id="fields">Fields</h1>
<pre style="background-color:#ffffff;">
<code><span style="color:#545052;">transaction_list: [array of Fingerprints]
nonce: unsigned 32-bit integer
timestamp: ISO 8601 <date>T<time>
hash: String
</span></code></pre><h1 id="hash">Hash</h1>
<p><code>tha</code> field in <a href="/jwt">jwt documentation</a> in fact stands for "The Hash", in the case of a post request for a block, you need to use hash field of the block. </p>
