Hi, First: I am a newbite to altcoin development, next to generate an altcoin from litecoin, 1- I have made a clone of litecoin using git clone https://githubcom/litecoin-project/lotecoin.git2- I changed some of chain and coin parameters in chainparams.cpp as below:

As you may know the bitcoin developers has omitted the genesis block mining code from source code published in github, but I fortunately found some piece of code in related blogs and it worked, then I have calculated the new Genesis hash, Merkelroot hash and Nonce and put into code as you can see above. The code was compiled correctly and I have not received Assertion failed message for Genesis block but I received another error which you can see in debug.log as below:

2017-12-15 07:31:33 ERROR: ReadBlockFromDisk: Errors in block header at CBlockDiskPos(nFile=0, nPos=8)
2017-12-15 07:31:33 *** Failed to read block
2017-12-15 07:31:33 Error: Error: A fatal internal error occurred, see debug.log for details
I found that this error(eg. ERROR: ReadBlockFromDisk: Errors in block header at CBlockDiskPos(nFile=0, nPos=8) ) occur in CheckProofOfWork function which is in pow.cpp, Any recommendation is appreciated. |
