<li>may change in the future as long as emission curve is preserved</li>

<h2 id="block-reward">Block reward</h2>
<ul>
<li>~6 XMR as of Dec 2017, see the <a href="https://moneroblocks.info/">latest block</a> coinbase transaction amount for current reward</li>
<li>smoothly decreasing and subject to penalties for blocks greater then median size of the last 100 blocks (M100)</li>
</ul>
<h2 id="block-size">Block size</h2>
<ul>
<li>dynamic, maximum of two times median size of the last 100 blocks (2 * M100)</li>
</ul>
<h2 id="emission-curve">Emission curve</h2>
<p><strong>Main curve</strong></p>
<p>First, the main emission is about to produce ~18.132 million coins by the end of May 2022.</p>
<p>As of Dec 2017 the emission is about 30 XMR per 10 minutes.</p>
<p>See <a href="https://www.reddit.com/r/Monero/comments/512kwh/useful_for_learning_about_monero_coin_emission/">charts and details</a>.</p>
<p><strong>Tail curve</strong></p>
<p>The tail emission kicks in once main emission is done.</p>
<p>It will produce 0.6 XMR per 2-minute block.</p>
<p>This translates to &lt;1% inflation decreasing over time.</p>
