Re: The genesis block is hurting my soul.. Please help [25 MegaCoin bounty]
Hi,
didn't read all the thread. But this will help you with Litecoin clients:
(this work only if you already did the basis (=change your timestamp, ntime, ect...) and ready to mine your merkle/genesis.)
- Open main.cpp
- Go to "bool InitBlockIndex()"
- Search "block.print();"
- ABOVE, you copy this:
This is a script that doing all the annoying job for you.
How to use it ?
- First you need to empty your merkleroot, genesis and nnonce (merkle = "0x", genesis="0x", nonce=0.
- Then you compil and start the client.
- The client will show an error but show the merkleroot.
- Now change you merkle root variable for your new one.
- Compil again and start again.
- Your client will try to mine your genesis block, this operation can be very fast as she can be very slow.
- After this, the client will show again an error but give you the genesis (gethash) and nonce.
- reopen your client script, change the genesis and nonce (and verify your ntime).
- REMOVE the script I gave you (or comment).
- Compil and enjoy
I don't know if someone got the bounty, but i'm not looking after, just helping =)
