Topic: Help with hashMerkleRoot - I've done my research just not getting very far (Read 2019 times)

All the data in your log there is invalid - except for the merkle root. You then need to instaer that into the hashmerkleroot bit in the code, compile, runa again, and it should crash at hashgenesisblock. Then you will need to open the debug again and add the block.nnonce and hashgenesisblock values. After that it should work without crashing

Hi All,
In the aim of learning and becoming more experienced with bitcoin/altcoin I have decided to create my own coin (not going to release it, just create it for the fun) but I am having problems when trying to run the daemon.
I get the error
So I had a read around google and came across a site which says to check the debug log, So I did and it showed me this
So I tried these settings in the code and rebuild but still get the same error. is there a more foolproof way to fix this or get the merklehash, I have been at it for hours
also, is there a merkle hash I can use for any coin, say if I wanted to create another one?
Regards,
Sanquin
