Great Article.
@karnel was actually looking to create a BitSDR MPA(Market Pegged Asset) on the Bitshares network recently. Similarly to BitUSD, the value of the token would always be worth at least 1 SDR worth of Bitshares (BTS) via the Bitshares Decentralized Exchange; issued by the network and honoured by the network itself making it free from government or third party intervention/influence. It would be a simple addition to as the witnesses already track and publish all the SDR currencies to the blockchain.
