Please advise me... I have been suffering from this problem for almost 4 months now.
I'm trying to clone bitcoin. I can't change the genesis block.
I used GenesisH0 to create a Genesis block as follows
$ python genesis.py -a SHA256 -z "06/06/2021" -t 1622938707 -n 1158615860
The output was as follows
04ffff001d01040a30362f30362f32303231 algorithm: SHA256 merkle hash: 200f703ffe7f3580d3a38309b207f76f1ab21db7bb4acd97656ba5518d7543ce pszTimestamp: 06/06/2021 pubkey: 04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef3 8c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f time: 1622938707 bits: 0x1d00ffff Searching for genesis hash.. genesis hash found! nonce: 1158615860 genesis hash: 000000003a3f2fd0e716571a94390b055c6c6388739845dd7bd66c3de04d2d13
====
Using this data, I pasted in the following.
genesis = CreateGenesisBlock(1622938707, 1158615860, 0x1d00ffff, 1, 50 * COIN); consensus.hashGenesisBlock = genesis.GetHash(); assert(consensus.hashGenesisBlock == uint256S("0x000000003a3f2fd0e716571a94390b055c6c6388739845dd7bd66c3de04d2d13")); assert(genesis.hashMerkleRoot == uint256S("0x200f703ffe7f3580d3a38309b207f76f1ab21db7bb4acd97656ba5518d7543ce"));

and
$ make $ ./testcoind
Then, I get the following error message.
testcoind: chainparams.cpp:129: CMainParams::CMainParams(): Assertion `consensus.hashGenesisBlock == uint256S("0x000000003a3f2fd0e716571a94390b055c6c6388739845dd7bd66c3de04d2d13")' failed. Aborted (core dumped)
All the code is below. I would appreciate your advice. Thanks.
