aabc / equihash-zcash-c Goto Github PK

And if yes how do I practically connect this with zcashd?

I use your algorithm to achieve a mining program，but could not pass the check of zcashd. Would you please point out the difference between your algorithm and the official one? Thank you in advance.

Can this solver be used to generate new zcash genesis block parameters?

Hi aabc.

Thanks a lot for your Code.

I am trying to use your code with the Setting 144/5 but it crashes always with this Error Message here.

**

basicSolver-opt: basicSolver-opt.c:93: expandArray: Assertion `out_len == 8 * out_width * in_len / bit_len' failed.

**

Please Help me fix it or help me understand what is the problem so i am able to fix it by myself.

Here is thw whole Output and how to reproduce the crashing !

Hi,

I assume this is the origin of this equihash implementation port to c I have stumbled upon in several other projects?

If so, I believe my request is best directed and solved here.

Am I missing something, or does this port not verify the algorithm binding condition (strict (i.e. no duplication in indices) lexicographical ordering + leading zeroes in 'subsolutions')?

Given that several mining pool projects seem to have adopted this code, I could see there being potentially some problems depending on how their share payout is set up, if rogue miners decide to take advantage of amortization costs submitting solutions that wouldn't be accepted by the network, but this verifier code seems to allow.

after done with READ instructions, I run cli api as described primarily:

./basicSolver-opt -n 200 -k 9 -i input.bin
then errors occured as stated in title, and CPU usage reaches 100%. input.bin is original one from this project, below are screen outputs:
