DASH mining after the Evolution (just in case)

[raganius]

I've heard that DASH Evolution will bring a solution to the mining hashrate "vulnerability", so maybe what I have here might not be of much importance for us anymore. But, anyway, I find it to be a good idea sharing, just in case:

It's about the paper "Majority is not Enough: Bitcoin Mining is Vulnerable", by Ittay Eyal and Emin Gün Sirer (Department of Computer Science, Cornell University)

Abstract. The Bitcoin cryptocurrency records its transactions in a public log called the blockchain. Its security rests critically on the distributed protocol that maintains the blockchain, run by participants called miners. Conventional wisdom asserts that the mining protocol is incentivecompatible and secure against colluding minority groups, that is, it incentivizes miners to follow the protocol as prescribed. We show that the Bitcoin mining protocol is not incentive-compatible. We present an attack with which colluding miners obtain a revenue larger than their fair share. This attack can have significant consequences for Bitcoin: Rational miners will prefer to join the selfish miners, and the colluding group will increase in size until it becomes a majority. At this point, the Bitcoin system ceases to be a decentralized currency. Unless certain assumptions are made, selfish mining may be feasible for any group size of colluding miners. We propose a practical modification to the Bitcoin protocol that protects Bitcoin in the general case. It prohibits selfish mining by pools that command less than 1/4 of the resources. This threshold is lower than the wrongly assumed 1/2 bound, but better than the current reality where a group of any size can compromise the system.

It seems to me there's some interesting information. I hope it can be useful, and contribute to our Evolution.

The way I understand it, the Dash miners will produce a number, and the quorums will be the 10 MNs that have a hash closest to the block hash from the past... some weird thing so that it's impossible to know which past has is going to be used ahead of time.

This way it cant be gamed in any way, and no way to know when your MN will be grouped in a quorum or with whom. And since every transaction will be an instantX transaction, in other words, controlled by the MN network, not miners) the miners will have no power to include anything in a block that wasn't first approved of by the Masternodes.

So yes, no more ability for anyone to double spend. Even if a MN manages to hoodwink it's quorum, it'll be seen by the others, and rejected. But I don't think it is possible to hoodwink the quorum unless you had control of every on
