Hi Sidehack,

if i understand correctly, the USB Mining stick or BM Chip cannot do a simple SHA256 hash... and we send only work thread hashing command to run hashing fron 0 to FFFFFFFF for a merkleroot , right?

So if i want to generate only merkleroot with transactions using a Gekkoscience USB mining Stick, it will not possible, right?
Do you think that will possible with another programmation?

Many thanks for your help

Hi,

after testing the cgminer and check the cgminer.c , i discover that the Merkleroot is generate using CPU-hashing instead of using the BM1384 chip.
Someone could explain me why?
Is there a way to use the BM1384 SHA256 Hash chip instead of CPU for hashing merkleroot?
We know there is a lot of transactions in a BTC bloc, with all testing and transactions, cpu can only generate 6 to 10 Merkleroot by sec.

I think we can do better, that will improve a lot if we use SHA256 chip to hash instead of CPU.

Do you think if it's possible?

my last question :-) is about how a Gekkoscience USB stick works? i have found a datasheet on the BM1384 chip or BM1387 Chip but dont know how it works? and how to dev on it.

If someone can help me to have clear vision on it, that will help me a lot.

Many thanks for your help

Hi Everyone,

I need to contact VH or Sidehack for a dev question on GekkoScience Mining USB stick.
is it possible than they contact me?

Many Thanks for your help
