Zoidberg is planning to bring in a Proof of Stake hybrid system into Boolberry. Dash's masternode system started out as a privacy mechanism for its coinjoin system but at it core it is basically a Proof of Stake layer that requires users have a 1000 coins to participate. By design their system is not very egalitarian and because of that it drives the price up by requiring users to have 1000 coins and those coins remain off market staking which also reduces the availability of the coin supply.
