You guys are the only community so far who have discussed this paper and platform

I will be speaking with the author and covering the finding in an article. Do you have any questions to forward that would be nice to include in the article (with your permission of course).

I find it very interesting indeed, though the preventative measures put into place in the case of a Quantum based attack seem rather superfluous. Should we approach such a stage, there are many bigger security issues to worry about than a cryptocurrency algorithm. I believe the other aspects are good in that it natively supports multiple chains and rewards those who have been delegated in helping the stake holders. The issue there is i am not sure whether decentralization is effected by such a move. Will it give stake holders or the systems delegated more power?

Any comments would be appreciated.

I can't speak for the whole community, only myself. But, I would be interested to know more about QDPOS in relation to our DPOS. Is it a fork of us, or a completely new implementation? It looks quite different to me. But, DPOS already involves queuing in the sense that our delegates are assigned an order in a queue to sign blocks so it's an odd name choice imo.

QDPOS looks to have a very large amount of possible delegates, DPOS has 101 delegates. Too small a number of delegates and the system risks centralization, to large a number and the delegates will not be earning enough that they would be incentivized to compete against each other for these few positions so that they can then use the earned funds to pay for improvements to the system and community. Is this the point? Do the devs plan on continuing to develop their coin themselves rather than opening it up to the wisdom of crowds in an open source manner like BitShares?

Why the move away from a democratic stake based system of voting in the delegates to positions? The great thing with DPOS is that bad actors will be voted out quickly and likely not reinstated. If everybody can be a delegate in QDPOS as long as they have the minimum stake requirements won't this make it a lot cheaper to disrupt the network compared to DPOS?

How does the system scale? How many transactions a second are possible?

No mention of BitShares at all in the tech stuff so I doubt they'll be honoring AGS/PTS.

Quote from one dev in this thread: https://bitcointalk.org/index.php?topic=857509.0;all:

There is some mathematical evidence that the encryption system we're using is in fact quantum-resistant, so we only need enough bits in the key to thwart a quantum search (Grover's algorithm). Also, we use merkle hash trees for signatures, and although there is no proof yet, there are no known quantum algorithms that can attack hashes other than a quantum search. To brute force a 256-bit hash would usually take 2256 operations, but Grover's algorithm only takes O(√N) time, so that's 2256/2 = 2128 quantum operations = 128-bit level quantum security.

He is referring to this paper: http://www.santafe.edu/media/workingpapers/11-06-021.pdf

Yeah, would be interesting to talk to him.

I don't think it's anything yet, first release isn't due until Fall 2015 according to the roadmap: https://wiki.qointum.com/roadmap/

Looks like he's promising lots and trying to raise funds to deliver...

Just came a across this: https://qointum.com/

It says it is going to be using Queued Delegated Proof-of-Stake... I'm just starting to read through the technical stuff now. Thoughts?

I've finished some more designs and included them with the others. I've made a sound wave in the shape of an "M" and an "N", liondani and feedthemcake's PTS and Play crossover designs and some mixes between "n" and "N" with musical notes including kickky's idea. Let me know what you guys think.

just a quick merger....

Looks good. Is it a fork or a merger? 

I met a wise older man at a crypto meetup the other month that introduced me to the concept of a gift economy. He recommended a book to me called Sacred Economics: http://sacred-economics.com/

I haven't read it myself, so I can't personally recommend it, but perhaps it may be of interest to someone reading this thread. He spoke very highly of it.
