Absolutely. This is an improvement over the “traditional” proof of stake minting scheme, at least to me. With other proof of stake systems, the act of minting is used to secure the block chain, but other than the finanical reward provided when you solve a block, whether an individual holder decides to mint or not is affected by the “tragedy of the commons”. For an extreme example:
Alice, a PoS coin holder thinks to herself:
Why should I waste time and effort trying to mint a block, when there are plenty of other people out there doing the same thing? I’ll just hang out and let Bob take care of it…
While at the same time, Bob is making his decision…
Alice and everyone else seem to have this minting thing taken care of. I don’t really care about the 1% reward, because it’s not going to change my situation very much…
End result: The block chain is not secure.
With Nu, the grant proposals, motions, and parking rates have a large impact on the day-to-day operations of the network, and as such, for a holder not to want to cast their votes can have a much larger impact finanical impact on their holdings than mearly not getting their block reward.
It’s not a perfect system, because some people will still decide not to vote even with all of the implications, but I feel it is a lot closer to a positive set of incentives than a pure monetary reward.
