Lets see if the question you asked either teaches you or me something new.
If 60% of a transaction quorum don’t want a transaction to be mined only because the transaction is not consistent with the hard coded transaction consensus rules within the masternode code base maintained by the dash-core development team.
If miners don’t like new masternode consensus rules, they don’t have to mine newly formed transactions associated with a new Dash code base. Miners must approve all new Dash-core code releases.
Dash transaction quorums are rotated every 24 hours from a pool of ~5K masternodes deployed around the World. The mathematics behind BLS threshold signature technology is applied to randomly select the next transaction processing quorum of 30 masternodes every 24 hours.
It is important to realize the Dash-core wallet is a Dash full node without extended Dash masternode behaviors that provide value added services such as voting on Dash Treasury proposals (funded by 10% of Dash mining proceeds), InstantSend, PrivateSend, and eventually services such as IPFS…
