Is there a jurisdiction where child pornography is not illegal?
<p>There is somewhat <a href="https://fc18.ifca.ai/preproceedings/6.pdf" rel="nofollow noreferrer">recent research (PDF)</a> which has found there to be at least links to child pornography on the bitcoin blockchain with also one one explicity file on the blockchain which may be classified as actual child pornography.</p>

<p>Now, assume there is actually a clear and indisputable case of child pornography on the bitcoin blockchain. This means that everyone who a) mines bitcoins and b) verifies the blockchain themselves have a copy of this file on their machine. </p>

<p>This raised (at least for me) the interesting question:<br>
<strong>Is there any country / jurisdiction in which it is not illegal to own child pornography (on your personal computer)?</strong></p>

<p>According to <a href="http://chartsbin.com/view/q4y" rel="nofollow noreferrer">this chart i googled</a> and the associated table, child porn is actually not explicitly illegal in most of the world. Basically, a bunch of countries in Africa, and a couple in Latin America and Asia, don't appear to regulate kiddie porn at all.</p>

<p>A couple of others (like Argentina, Russia, and South Korea) allow possession, but not distribution.</p>

<p>A couple of countries protect "virtual" kiddie porn (cartoons, computer renderings, etc where no actual child is being abused). The US is among these. (Pretty much has to be, due to the First Amendment.) Obscenity laws may apply, though.</p>
