If it's technically feasible, all new DACs can be based on the blockchain of BTSX, then bidUSD can be used among those DACs, just like XCP and MSC are BTC blockchain based. Then cross chain transaction can be realized.
Then a DAC can issue bitasset in btsx, whereas this bta is the basic currency of that DAC, like the current NXT asset.
All DACs are independent, so their wallets are independent, development team is independent, but blockchain are shared.
New DAC will honor ags, pts 10% and can still IPO, etc...
There is only one DPOS/delegates system, because all other DAC are based on BTSX blockchain, and transaction fee is btsx.
All IDs in different DACs are indentical, mailing system supports cross chain communication
PTS is still liquid, but as bitasset in BTSX
AGS is still inliquid.
The only disadvantage is a bigger blockchain, but can be resolved by light wallet or other technique, anyway BTS is going to do that.
The above is not my opinion, but translated as requested by a few users in Chinese board.
Any discussion is appreciated.
