Yea..unfortunately dev. hasn't shown up so that is the cause of price dwindling...If someone with good tech skills can help dev. or possibly take over until he is back that'd be great.
I think 'prime' proof-of-work is interesting, but that it will ultimately result in an economic failure for data storage.
I'd like to propose a gradual (but requiring a hard-fork) upgrade to 'proof of data' which would just be to find sha 256 hash of the required difficulty *over the entire blockchain*. This basically means your hash rate is proportional to how fast you can read the blockchain off disk (or you keep it in memory)
It might have to be implemented as something that uses a pseudo-random number generator so that each block only requires a deterministic, but psuedorandom sequence of blocks, (a subset of the blockchain) so that you cover the entire blockchain over a a few hundred blocks
Thoughts anyone? Good idea? Bad idea? Something to do first in a new coin?
