RVN will be moving to KawPow which is a modified version of the ProgPOW algo.This needs looking into as headers change with this new algo.

Scope of work:

• Add new RVN Header which has uint64 nonce ,and blockheight to serializeheader.
• Add hasher to create mixhash for KawPOW.
• Add KawPoW verifier natively.

Doing some final testing and the I PR

[akshaynexus]

ok

[mul1sh]

@akshaynexus Sorry but it seems i'll actually need a few more days to continue testing out different approaches and understand how to best integrate kawpow into the current stratum protocol.

Reason for this is that I understand how the current kawpow works based on the above node.js example provided, but when I try to replicate it this pool, it doesn't produce any blocks so definitely my current implementation is not correct.

[akshaynexus]

Ok,it may help.to have a wip pr so I can test the current implementation

[mul1sh]

@akshaynexus Sure definitely, kindly let me send it over in a few

Can you add a Kawpow Algorithm?
I think there are no other interested developers left than you.

Any chances this get worked on again? I know it hasn't been updated in a while but I'd be willing to help if I can. Official version has implemented libkawpow, but that's about it.
