I think basing our system on DPOS is a positive thing as it has proven to be one of the most influential, stable, and secure systems we have seen.
I suggest to analyze the issue described in
https://bitcointalk.org/index.php?topic=913075.msg10184529#msg10184529 before moving further.
Or set the security limit to 67 delegates instead of 51 until we get a formal proof that 51 is indeed enough.
Thanks for your comments! Number of delegates is one of the things we are paying very close attention to and discussing internally. As mentioned, we will be making some changes and tweaks to our version of DPOS. After 0.1.9 is officially out and the network looks good, we will start discussing our DPOS solution much more. We would love to get your input as we release more information and discuss how we plan to implement. We actually have it ready to enter testing and will have an extensive test phase to ensure we are happy with everything.
Any other input or your outlook on DPOS or possible areas of interest would be great to hear! Thanks!
