algo=quark (for quark pool )
and
algo=scryptn (for scryptn pool)
Both on dedicated servers
It looks like your pool is submitting the wrong block version number.
From core.h
// primary version
BLOCK_VERSION_DEFAULT = 2,
// modifiers
BLOCK_VERSION_AUXPOW = (1 << 8),
// algo
BLOCK_VERSION_ALGO = (15 << 9),
BLOCK_VERSION_SCRYPT = (1 << 9),
BLOCK_VERSION_GROESTL = (2 << 9),
BLOCK_VERSION_SKEIN = (3 << 9),
BLOCK_VERSION_QUBIT = (4 << 9),
BLOCK_VERSION_X11 = (5 << 9),
BLOCK_VERSION_QUARK = (6 << 9),
BLOCK_VERSION_GROESTL2 = (7 << 9),
BLOCK_VERSION_BLAKE256 = (8 << 9),
BLOCK_VERSION_X13 = (9 << 9),
BLOCK_VERSION_SCRYPTN = (10 << 9),
BLOCK_VERSION_KECCAK = (11 << 9),
So for a Quark block, your pool should be using block version 2 || (6 << 9) = 2 || 3072 = 3074
maybe you can explain us what are the diference from Quark to Spectrumcoin .... also what are from Vertcoin to Spectrumcoin .... in this case will be more easy for us to create the best setup for pools.
