I get accepted shares but the blocks found are rejected.. I cannot see a different block structure at first sight, searching for a difference now
Saffroncoind uses a different Blake algorithm than Blake coin. There exists Blake and Blake-2.
There is no GPU miner released for Saffroncoin's Blake algo, but judging by the difficulty (52), there might be a GPU miner (or a botnet) on it.
I think I've got the Algo right, it seems to be a problem with final block creation, there might be some extra information or a different block header which I'm missing.. Maybe one of the devs has a tip for me, currently I cannot find the difference
