We are working on BIG update. As you may know, we like "quantum leaps" like we did with duck->dark.
Meanwhile PoS/PoW hybrid, Aliases and multisignutares, and some other "messaging" functions will upside down all you know before about cryptos. You just need to wait, and we just want to keep a little mystery, one reason is because we do not want to interrupt the dev process because of unnecessary excitement and anticipation caused by the inevitable future success of DarkNote.
