I made an attempt to get a huge feedback from the community's active members on this question, but my Poll was flawed as it was "leading" so I will try again.

    This isn't an issue that can be decided in any good measure by vote. It's a matter of technical merits and the right incentives, so I'll just wait out to see what people with more technical knowledge have to say.

    Do not allow mining centralization to happen, and FPGA/ASIC. If possible prevent GPU mining.

    avsa, you are right, though I think "community sentiment" could be used to guide development. For example, if we had a 1000 votes for 100% PoS, against a handful of PoW or a combination, then obviously, developers couldn't be blind to that "sentiment" of the community.

    Seeing that there were a few votes, and that this community is probably highly technical, I think you are right, and the issue comes down to "technical merit"

    obviously, I'm one of the stary-eyed PoS believers, hoping that we can have a safe, reliable, and functional system with minimal extra use of resources beyond what is absolutely necessary.

    PoW tends to become relatively centralized, but it's impossible to fake or duplicate. PoS is more distributed, but it can be duplicated rather easily. I suspect that a PoW/PoS combo will do it: PoW to harden the currency base and make it hard to forge from the root, PoS to interconnect the mined blocks to make it hard to forge a branch and prevent the PoWer from getting too much leverage in the currency.
