Ok, you say "This mechanism is currently being used with great success in the NuBits and NuShares network." Well, I'm a three months Nushare holder in your six months old Nubits/Nushares system and didn't see in all this time a single dime in dividends. All I have seen is nubits custodians losing funds in hacked/adminrunnered exchanges and Nushares holders being diluted trying to compensate the custodians lost.
I just wanted to say something about this real quick. While all Nu shareholders are entitled to receive a percentage of the dividends based on how large their equity stake is in the network, it is however not guaranteed that dividends will be given at all. In order for there to be dividends, there needs to be profit for the network. Just think of Nu as a decentralized business in this case. No one in the business should receive dividends if there is no profit.
Unfortunately as you mentioned, shareholders were the victims of 4 centralized exchange failures in which a lot of shareholder funds were lost. If shareholders want to receive dividends, then they need to work hard to figure out how to prevent things like this from happening and to figure out new ways of making profit. If the employees of a business don't put in the hard work and effort, then they won't receive the reward.
Since the February hackings, shareholders have been working hard on these issues. One of the main reasons so much money was lost was because we still had a centralized liquidity operation, with only several liquidity providers managing all the money on these exchanges. To help prevent shareholder funds from being lost again, we've been working on decentralizing our liquidity operations through the development of liquidity pools, in which anyone can join in with their own funds and provide liquidity for the Nu network, also getting paid for it. People don't even need to be elected as LPCs anymore in order to provide liquidity. They simply need to join the pool with their own funds and collect interest.
Another way to prevent this from happening again is Jordan's work on this decentralized exchange, in which our liquidity operations will be protected from hackings and theft. Nu shareholders are still very much in the process of perfecting their product. It's still going to take a long time and a lot of hard work. In my opinion, this is a project that will most likely take years before we see large and consistent profits. I believe we'll get there eventually though, as long as shareholders continue to solve problems and we continue to expand into new areas and figure out new ways of making profit.
