Dirac Coin (XDQ) is planned to be traded in conjunction with Nautilus coin - which introduced the concept of free-market managed economic stability. Dirac is a Blake-256 algorithm based coin with a block target of 180 seconds and difficulty retargetting every 2016 blocks. The coin cap is limited to 2.272 million coins and the block reward reduces in various steps to 0.01 XDQ from an initial 8XDQ.
