I am trying to create my own genesis block using the bitcoin source code but my new hashes are not being accepted by the assert statements.

Step 1:

I have changed the pszTimestamp variable in chainparams.cpp to generate my own genesis hash.

I have added into the code some print statements to check the genesis hash and merkle root as they are generated from my new pszTimestamp.

The hashes I have generated are:

MERKLE ROOT:9f46bcd8a56be2b6b022acbcc859b201534c21801b1b73685a69de17ad37665e

GENESIS HASH:cc45935bfeb12faacc8ab2797d2f5507f7eef8a44c597f3622c704cc0af8a648

Step 2:

I have changed the assert statements below to assert the new hashes on line 131 and line 230 of chainparams.cpp

The Genesis Block assert(consensus.hashGenesisBlock==uint256S("0xcc45935bfeb12faacc8ab2797d2f5507f7eef8a44c597f3622c704cc0af8a648"));

The Merkle Root assert(genesis.hashMerkleRoot==int256S("0x9f46bcd8a56be2b6b022acbcc859b201534c1801b1b73685a69de17ad37665e"));

However…

These assert statements still fail. Why?

I have included the error message below:

bitcoin-qt: chainparams.cpp:230: CTestNetParams::CTestNetParams(): Assertion `consensus.hashGenesisBlock == uint256S("0xcc45935bfeb12faacc8ab2797d2f5507f7eef8a44c597f3622c704cc0af8a648")' failed. Aborted (core dumped)
