We have been working to upgrade Blue and get it to this stage for months, however we're always looking for ways to innovate and improve our existing code-base.

We're tentatively looking at the work the BlackCoin community is doing with PoS 2.0 http://www.blackcoin.co/blackcoin-pos-protocol-v2-whitepaper.pdf.

As more improvements come to light (I.E Cold Minting), we will be integrating these solutions within due time.

Our next goal is to work on getting more users involved and using the currency.
