World of warcraft game has always kept a secret how game used the currency. GOLD ingame cryptocurrency.
When the game came out, everything could be trades by hash value.
You famed and you got rewarded a little bit of copper or silver from that kill and to generated a new spawn you need to wait for a new md5 hash to be generated by the system.
The format has always been known to be MD5 hashing algorithm and thats why duping and exploting cryptocurrency in WOW has never been possible.
Now the secret is out, Blizzard World of warcraft is the creator.
maybe you should provide us with more information on this. I did not real see the connection. We have many theories on this subject and that makes it difficult for us to believe in any new one.
