Thank you very much rlh for the concise and thorough analysis. It is clear to the world now that Qora is something special. From your comments, it appears that Qora employes a unique combination of cryptographic algos while the forging aspects are not yet clearly validated. Time will tell of specific details but your analysis sure has helped us "non-coders" have more confidence in Qora not only as not being a clone but also as being a well-written piece of work (not that I ever doubted)  

I wonder if a lack of open, forging accounts is responsible for some of the past issues Qora has had with wallets having no connection (lack of syncing). If this alone is the reason, I think we need to consider a means to increase full-time nodes: at least 100 imo. If the code is the issue, I noticed bounties for bug finds which could alleviate this problem. I have only occasionally had connection problems and I think this is the result of not enough forgers and only a few "huge" accounts forging, creating multiple chains. Now that more are coming into the community, I think this issue will take care of itself but something to consider as a priority.
