Byte cent is cpu only and is resistant to botnets and supercomputers. Primes per second / hash rate is limited to that of a high end i7 cpu and you cannot mine multiple instances to one wallet. Wallet must hold x byte cents to mine without entering a capcha code. Genius.
Not genius, actually opposite
Here are some simple PoW rules
1) inexpensive to verify vs generate
2) difficulty adjustable in both directions
Primes only get
bigger.
Dedicated cpu miners use Aws instances which they pay for, as a result, we have to maintain that PoW remain a fire and forget solution. A lot of people confuse cpu mining with home/desktop mining., there is NO known effective method of PoW that cannot be replicated on a larger computer.
As for the claim of not being able to mine multiple instances to one wallet, LOL , what a load of dung (not u, the developer). The only thing that matters is the block chain, seeing as it does not recognize or record how many instances I am running, I can just modify the source code to allow it without in anyway creating a fork. How one mines is not something that can be controlled.
It is not everyone that owns a high end I7, as a result, byte cent is a community failure as it alienates the majority cpu owners. I'd say most play with dual core and quad cores, the most popular being the moderate I5.
Perhaps I am wrong, but mining should not require any input other than your hardware. The stipulation of minimum balances and captcha codes are barriers to entry and have the effect of driving away potential users.
I think that momentum is a successful attempt because
1) it's target exclusions are the small business computers which make up the majority of botnets.
2 while GPU mining is available, it's scale vs cpu mining is similar to just having a next generation processor, and if the launch is fair, even that advantage is lowered by scale.
3) momentum can easily be modified to suit any conditions as evidenced by the existing 3 unique variants
Today I focus on cryptonote based coins, just to get a feel of what is going on in there.
