Where one SHOULD see
if (true && block.GetHash() != hashGenesisBlock)
in src/main.cpp of my new crypto, one sees
uint256 hash = block.GetHash();
printf("%s\n", hash.ToString().c_str());
printf("%s\n", hashGenesisBlock.ToString().c_str());
...
The genesis miner is not included in the litecoin sources. You need to add it yourself: http://pastebin.com/aKgggRvZ
Going to check up on this and implement, give me some time. - Olu
To ensure I'm not derping around:
//// debug print
uint256 hash = block.GetHash();
printf("%s\n", hash.ToString().c_str());
printf("%s\n", hashGenesisBlock.ToString().c_str());
printf("%s\n", block.hashMerkleRoot.ToString().c_str());
assert(block.hashMerkleRoot == uint256("0xa73e546160e2999f9f17fcfc76c422a04b00acd5846a90a784593951b0987380"));
// If genesis block hash does not match, then generate new genesis hash
if (true && block.GetHash() != hashGenesisBlock)
{
printf("Searching for genesis block...\n");
// This will figure out a valid hash and Nonce if you're creating a different genesis block:
uint256 hashTarget = CBigNum().SetCompact(block.nBits).getuint256();
uint256 thash;
char scratchpad[SCRYPT_SCRATCHPAD_SIZE];
loop
{
#if defined(USE_SSE2)
// Detection would work, but in cases where we KNOW it always has SSE2,
// it is faster to use directly than to use a function pointer or conditional.
#if defined(_M_X64) || defined(__x86_64__) || defined(_M_AMD64) || (defined(MAC_OSX) && defined(__i386__))
// Always SSE2: x86_64 or Intel MacOS X
scrypt_1024_1_1_256_sp_sse2(BEGIN(block.nVersion), BEGIN(thash), scratchpad);
#else
// Detect SSE2: 32bit x86 Linux or Windows
scrypt_1024_1_1_256_sp(BEGIN(block.nVersion), BEGIN(thash), scratchpad);
#endif
#else
// Generic scrypt
scrypt_1024_1_1_256_sp_generic(BEGIN(block.nVersion), BEGIN(thash), scratchpad);
#endif
if (thash <= hashTarget)
break;
if ((block.nNonce & 0xFFF) == 0)
printf("nonce %08X: hash = %s (target = %s)\n", block.nNonce, thash.ToString().c_str(), hashTarget.ToString().c_str());
++block.nNonce;
if (block.nNonce == 0)
{
printf("NONCE WRAPPED, incrementing time\n");
++block.nTime;
}
}
printf("block.nTime = %u \n", block.nTime);
printf("block.nNonce = %u \n", block.nNonce);
printf("block.GetHash = %s\n", block.GetHash().ToString().c_str());
}
block.print();
assert(block.GetHash() == hashGenesisBlock);
This is what the main.cpp looks like now, but do I have to change the instances of
// Special case for the genesis block, skipping connection of its transactions
// (its coinbase is unspendable)
if (GetHash() == hashGenesisBlock) {
view.SetBestBlock(pindex);
pindexGenesisBlock = pindex;
return true;
AND
// Get prev block index
CBlockIndex* pindexPrev = NULL;
int nHeight = 0;
if (hash != hashGenesisBlock) {
?
Nevermind, ignore this mid-level (low-level) silly crypto-currencyphile. I tried running everything as is and it couldn't build because the word "loop" present within the code you gave me should be replaced with "while (true)". I forgot that (maybe you did too?) for the most part just "loop" doesn't exist in C++. Thanks for the link Solcoin Project.
