I just built cpuminer for example and its minerd program chokes on a coin thatminerd claims has a block version of 6.
I believe the block version 6 might be something to do with proof of stake? Some hybrid proof of work / proof of stake coins use that version number for their blocks?
What do people use to CPU-mine such coins?
(Please, no "the difficulty is too high for CPU mining" claims, not every such coin stays popular enough to keep ASIC and/or GPU folk mining it forever, and I am looking into purportedly-dead coins here so...
)(Also, authors of bitcoin miners are often, it seems, against alt-coins, so I will not be surprised if when I set up GPUs I find GPU mining programs have the same problem; I have no GPU machines running right now and have no scrypt ASICs and this particular coin happens to be scrypt so I cannot check whether ASIC-mining programs also have the same problem...)
