Add support for SPR coin

[fpatron]

Hello,

I'm trying to add spectre coin which is a kaspa fork with a private algorithm.
https://github.com/spectre-project/spectred
https://github.com/spectre-project/go-spectrex

Spectre is a fork of Kaspa introducing CPU-only mining algorithm SpectreX.
SpectreX is based on AstroBWTv3 and proof-of-work calculation is done in the following steps:
Step 1: SHA-3
Step 2: AstroBWTv3
Step 3: HeavyHash

I follow differents commits about this issue (#57 (comment)) but it fails during job attribution.
I think its about algorithm which isn't implemented in miningcore.

Could you help me to implement spectrex algo? Give me some tips

Thanks in advance

Hello,

I can't really help, the source code you provided is golang, i'm terrible with that language. The easiest way for you would be to ask for a C/C++ portage of the algo and then make the implementation if you are good in C/C++.

It's also a tricky one since they are using another key hashing algo in AstroBWTv3 called salsa20. It won't be an easy implementation to be honest.

not as fast as a c/c++ implementation but there is one based on the go source code: https://github.com/1oopio/miningcore/tree/master/src/Native/libastrobwt

It's actually the one he linked in his request :)

Welcome back by the way, i remember last time we talked you were saying not being interested anymore with miningcore.
Glad to see your interest finally came back lol

Unfortunately it's like a very unhealthy habit and I cant keep my fingers off completely.
