I am making my own alt-coin, and I have mined the first genesis block hash(after some time), Merkle hash, nnonce and time. I am running on Ubuntu14.04.

But when I run ./bitcoind I get this error

Error: Incorrect or no genesis block found. Wrong datadir for network?

What does it mean? how do I fix it?

Here is debug.log shows:

  • Can you paste debug.log content? Anyway it looks like your daemon isn't able to find the desired path to the blockchain data folder. If you can post your debug I could maybe give you a more precise solution.

  • Try delete /home/boodu/.booducoin folder and restart daemon. If not working maybe you have some errors in the code itself or in the genesis hash generation process. If you need more help to fix it please contact me at [email protected] or on this thread: bitcointalk.org/index.php?topic=3196213.0 Regards.
