I don't think so.
He's talking about mining centralisation which affects all POW coins.
That's what I thought, but am I correct in thinking that with the 2nd tier quorum structure DASH will rely far less on POW mining for its security because miners don't have all the power and because DASH is based on X11 we are far less likely to be in the same situation as Bitcoin regarding the centrlisation of mining hardware and the concerns relating to that?
Actually, if you look at the plans for Evolution, which should come out in it's basic form this year, miners will no longer have a say in what goes into blocks. Masternodes will be split into quorums which will decide on inclusion to the blockchain. Miners actually post it into the blockchain's ledger, but if they don't do what the MNs say, or if they try to include anything else, their block will be rejected and the next miner to find a block will get the rewards if he properly builds it.
Will we still need miners? Yes, the mining has is used to randomly group masternodes into groups of quorums which process all transactions.
So, in this way, Dash DOES solve the problem.
Dash's Masternode network will process all transactions in randomly assigned groups called quorums.
Dash's Masternode network is large and very decentralized, with largest holder having around 400 MNs or 11.5% of the MN network. The chances are infinitely small that he will ever get control of a randomly selected quorum. This is much more secure than any mining solution out there. And entropy, the law that states things become more dispersed over time, is actually true, and Masternodes are always changing hands, and those with the most, will undoubtedly sell them off (or their children will inherit and thus distribute, etc...). It's virtually impossible for anyone to collect more than 20% of all Masternodes at this point, and if they did, they would have driven the price up exponentially.
Masternode Quorums are also capable of handling as many transactions as can be thrown at them. At the current size of the Masternode network, Dash can handle as many transactions per second as Visa does. But Dash is infinitely scalable. By reducing the collateral requirement for a Masternode by half, Dash can instantly double the Masternode network and handle twice as many transactions.
What about the cost of bandwidth and storage of this blockchain, which would surely grow? Dash's Masternodes are compensated. They must put up collateral to run a Masternode on the network for security reasons, but in doing so, they earn 45% of the block reward. The miners also earn 45% and the last 10% goes toward the budgeting system.
Now you will ask, surely, with such a huge blockchain, nobody will be able to use a full node in any practical sense. So they'll be forced to use a centralized service with a lite wallet. But you would be partly wrong. Yes, most people, for practical reasons, will use lite wallets. This would be inevitable for any coin. However, Dash lite wallets will be tapping directly into the network, through a decentralized API system, and retrieve their information instantly, securely, and directly from the network through Masternodes, without worrying about using a centralized repository.
I'd like to point out that the subject of the axiom of block size to node distribution size was presented by Evan at the last conference. I'm not sure if he was the first, but I think he was because I remember him collecting information to make a chart.
Now, again, he's calling number of miners withe full nodes "anonymity" he's not talking about personal-user anonymity, but of the anonymity and what I would think is more accurate, autonomy of the miners. Why is relying on Masternodes better than miners? Because, as has been proven since their inception, they have been growing. There are always more and more people buying Masternodes, thus the distribution is getting better and better. Many argue that the biggest holders can quickly earn enough coins to create more masternodes, increasing their share of the system, but this is actually not true. Aside from the fact that they have to run or have someone run for them, high quality servers, use bandwidth, etc... and pay for it, there are a lot more coins comeing into the system than what they're earning, and thus, we can predict that 1/2 of all coins created end up in Masternodes. Evan or someone charted the possibilities and it showed that even our biggest Dash holder, otoh, can not increase his % of the Masternode Network, unless he keeps binging in funds from outside the network (that is, buying up all the coins created)
This presentation actually suggests we create a new Federal Reserve, LOL. Yes, it's the "easy way out" but lets face it. It's a complete failure if "representatives" have to be used to mine blocks. I can't believe anyone that is in Bitcoin could think this way.
Besides that, Dash has solved the problem. Entropy ensures we'll never be more centralized than we are today, but rather that we will become more and more decentralized over time. Market pressures ensure nobody will be able to buy up enough Masternodes to control the system (requires so many, like 90% or more of the network, even in Evolution) that market pressures will ensure that even a country as wealthy as the United States wouldn't be able to buy up enough.
Done.
Dash Evolution is just about perfect.
