(0xD9B4BEF9 for Bitcoin, 0x0709110B for Testnet, FBC0XB6DB for Litecoin, etc...).  This seems like a good candidate for identifying coins, and also supports Testnet cases well.  Maybe there are some alts without such a magic number that might prevent that?&#xA;&gt; &#xA;&gt; -Allen&#xA;&gt; &#xA;&gt; &#xA;&gt; On Thu, Mar 27, 2014 at 10:43 AM, Jeff Garzik &lt;jgarzik at bitpay.com&gt; wrote:&#xA;&gt; On Thu, Mar 27, 2014 at 3:09 AM, Tamas Blummer &lt;tamas at bitsofproof.com&gt; wrote:&#xA;&gt; &gt; A notable suggestion was to instead of building a directory of magic numbers&#xA;&gt; &gt; (like 0 for Bitcoin, 1 for Litecoin etc) use a hash of the word &#34;Bitcoin&#34;,&#xA;&gt; &gt; &#34;Litecoin&#34;, &#34;Dogecoin&#34;, so collosion is unlikely and&#xA;&gt; &gt; cetral directory is not needed.&#xA;&gt; &#xA;&gt; +1 good idea&#xA;&gt; &#xA;&gt; --&#xA;&gt; Jeff Garzik&#xA;&gt; Bitcoin core developer and open source evangelist&#xA;&gt; BitPay, Inc.      https://bitpay.com/&#xA;&gt; &#xA;&gt; ------------------------------------------------------------------------------&#xA;&gt; _______________________________________________&#xA;&gt; Bitcoin-development mailing list&#xA;&gt; Bitcoin-development at lists.sourceforge.net&#xA;&gt; https://lists.sourceforge.net/lists/listinfo/bitcoin-development&#xA;&gt; &#xA;&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20140327/1242a957/attachment.html&gt;&#xA;-------------- next part --------------&#xA;A non-text attachment was scrubbed...&#xA;Name: signature.asc&#xA;Type: application/pgp-signature&#xA;Size: 495 bytes&#xA;Desc: Message signed with OpenPGP using GPGMail&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20140327/1242a957/attachment.sig&gt;</html></oembed>
