<p>I believe that many of the blockchain.info public addresses are self reported or crowd reported. There is a link where you can submit an address. </p>

<p>I wonder how sites such as <em>blockchain.info</em> resolve the owners of public bitcoin addresses. For example, <em>blockchain.info</em> knows that the <em>xkcd</em> donation address 14FHqYSgA... belongs to <em>xkcd.com</em>. It is available at <em>xkcd.com/bitcoin</em>, but somebody must be crawling all websites searching for that folder, right?</p>

<p>I assume there is a directory where this kind of websites are stored so that blockchain.info can look it up. Where is it and is there a public API available?</p>

<p>Thanks!</p>

# How does blockchain.info resolve adresses?

(Asked by: username_0 on 2013-04-20)

I wonder how sites such as *blockchain.info* resolve the owners of public bitcoin addresses. For example, *blockchain.info* knows that the *xkcd* donation address 14FHqYSgA... belongs to *xkcd.com*. It is available at *xkcd.com/bitcoin*, but somebody must be crawling all websites searching for that folder, right?

I assume there is a directory where this kind of websites are stored so that blockchain.info can look it up. Where is it and is there a public API available?

Thanks!

There's no central directory for this information. You could scrape [the Blockchain list](http://blockchain.info/tags) if you wished, but if you do so you're relying on the accuracy of their information.
