Edit: For the sake of possible future readers, rather than handing them a fully baked solution, I will just give outline of the procedure. Y'know. give man a fish / teach him to fish and so on... So if you want to get a new genesis block out of Darkcoin that uses X11 or any coin at all that has been forked out of Bitcoin, here are the steps, most of which can be inferred from this thread also. You need to change szTimesstamp and nTime. Zero the nonce, merkle root and old genesis block. Compile and run. Boom. Here's the genesis block and merkle root as they come from the printf statements in InitBlockIndex(). If you substitute them into the code, your gen block will be accepted, but you will run into this: hash doesn't match nBits. The code snippet (see above) that begins with if (true && block.GetHash() != hashGenesisBlock)
will help you to find the right hash and nBits. You just need to read what it does. It is looping an algorithm and increasing nonce to find a block that satisfies the difficulty. I.e. it is mining. Is it running scrypt? No it isn't, this is X11, so get rid of all that. Where do you get the X11 algorithm? Take a look at the error message you're getting. That should be enough... I think this is the best way to handle it. Teaching people to fish that is.

did not work, it failed.
Worked for me. What error report? PM you error message yesterday.btw, found X11 relate gen code, not sure if this is valid... if (true && block.GetHash() != hashGenesisBlock) { printf("Searching for genesis block...\n"); uint256 hashTarget = CBigNum().SetCompact(block.nBits).getuint256(); uint256 thash;

Haha... you are part of some jealous assh#ole herd, I see assh## like you never help anyone & can't stand anyone else helping out as well. If anyone needs help with genesis please contact me, I will help out for free.

See what you guys mean with X11 errors. I've played around with Scrypt in the past and it's pretty much plain sailing but with x11 PoS it's been an absolute nightmare so far... Even after getting what appears to be valid merkle root, nonce and genesis hash, it still fails when running on both testnet and main-net with this error: Assertion `block.GetHash() == (!fTestNet ? hashGenesisBlock : hashGenesisBlockTestNet)' failed. I've taken Yarkol's advice and it has been pretty helpful but if the debug.log clearly states these values and no other errors, then I'm a loss as to why the genesis blocks aren't being created. Opened LevelDB successfully CBlock(hash=000030b4df1fca238412d3acb536f920fb3fe4fc2b1255c40e78d54ac791e1ac, ver=1, hashPrevBlock=0000000000000000000000000000000000000000000000000000000000000000, hashMerkleRoot=00f5217426974f0aae85ef32ed69f99543993ebb8e995c4089febecd87f5e1b5, nTime=1401124588, nBits=1f00ffff, nNonce=29392, vtx=1, vchBlockSig=) Coinbase(hash=00f5217426, nTime=1401124588, ver=1, vin.size=1, vout.size=1, nLockTime=0) CTxIn(COutPoint(0000000000, 4294967295), coinbase 00012a4154686973206973206f6e652070656173616e7473207265766f6c742074686174204272757373656c732063616e6e6f74206a757374206272757368206173696465) CTxOut(empty) vMerkleTree: 00f5217426 block.GetHash() == 000030b4df1fca238412d3acb536f920fb3fe4fc2b1255c40e78d54ac791e1ac block.hashMerkleRoot == 00f5217426974f0aae85ef32ed69f99543993ebb8e995c4089febecd87f5e1b5 block.nTime = 1401124588 block.nNonce = 29392 CBlock(hash=000030b4df1fca238412d3acb536f920fb3fe4fc2b1255c40e78d54ac791e1ac, ver=1, hashPrevBlock=0000000000000000000000000000000000000000000000000000000000000000, hashMerkleRoot=00f5217426974f0aae85ef32ed69f99543993ebb8e995c4089febecd87f5e1b5, nTime=1401124588, nBits=1f00ffff, nNonce=29392, vtx=1, vchBlockSig=) Coinbase(hash=00f5217426, nTime=1401124588, ver=1, vin.size=1, vout.size=1, nLockTime=0) CTxIn(COutPoint(0000000000, 4294967295), coinbase 00012a4154686973206973206f6e652070656173616e7473207265766f6c742074686174204272757373656c732063616e6e6f74206a757374206272757368206173696465) CTxOut(empty) vMerkleTree: 00f5217426 The testnet (the output above) and main-net genesis hashes have been added into main.h but it still fails to run?

@PereguineBerty It's hard to say what the issue exactly is, but hardly a x11 error if you haven't got past the hash identity assertion yet. Maybe you could start by simplifying this a little !fTestNet ? hashGenesisBlock : hashGenesisBlockTestNet) i.e scrap the ternary operator, feed straight values into it so you can begin to track down why the block hash isn't the same as your gen block hash

Thanks for the info YarkoL. I managed to get it working fine today. After doing the same thing a long time ago with Scrypt, I recollect it taking a while to grind through a range of hashes and nonces. Thought this was going to happen again and it threw me off the trail because all the correct stuff was there instantly and it seemed too good to be true, so I ignored it (stupidly) ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Got issues with segmentation faults and missing setgenerate RPC commands now. Oh happy days!!!

Can someone please help me? This is what I have in main.cpp: const char* pszTimestamp = "14 June 2014 Soceroos lose to Chile 3-1 in FIFA world cup"; CTransaction txNew; txNew.nTime = 1402712622; txNew.vin.resize(1); txNew.vout.resize(1); txNew.vin[0].scriptSig = CScript() << 0 << CBigNum(42) << vector<unsigned char>((const unsigned char*)pszTimestamp, (const unsigned char*)pszTimestamp + strlen(pszTimestamp)); txNew.vout[0].SetEmpty(); CBlock block; block.vtx.push_back(txNew); block.hashPrevBlock = 0; block.hashMerkleRoot = 0; block.nVersion = 0; block.nTime = 0; block.nBits = 0; block.nNonce = 0;
//// debug print assert(block.hashMerkleRoot == uint256("0x0")); block.print(); assert(block.GetHash() == (!fTestNet ? hashGenesisBlock : hashGenesisBlockTestNet)); assert(block.CheckBlock()); And in debug.log all I get is: CBlock(hash=694b3a55a61339b43c01421b13f710e22e33a7eabda1cd48103bb9f376081d16, ver=0, hashPrevBlock=0000000000000000000000000000000000000000000000000000000000000000, hashMerkleRoot=0000000000000000000000000000000000000000000000000000000000000000, nTime=0, nBits=00000000, nNonce=0, vtx=1, vchBlockSig=) Coinbase(hash=b89a899f43, nTime=1402712622, ver=1, vin.size=1, vout.size=1, nLockTime=0) CTxIn(COutPoint(0000000000, 4294967295), coinbase 00012a393134204a756e65203230313420536f6365726f6f73206c6f736520746f204368696c6520332d3120696e204649464120776f726c6420637570) CTxOut(empty) vMerkleTree: What did I do wrong? (i'm trying to replace 0x0 with the Merkle Root)

try moving the block.print() statement before the assertion

I hope someone can help me out with my pb I got genesisblock on testnet, I try to test mining my testnet coins. I use 2 computers with each one ubuntu VM and different IP. I launch daemon and I try to get my PCs connected I use the following cmd: ./myCoind -testnet with following config: rpcuser=user rpcpassword=pass server=1 addnode=ip_PC1 addnode=ip_PC2 rpcport=xxxxx listen=1 My pb is i can't get connections with PC1 and PC2. "walletversion" : 60000, "balance" : 0.00000000, "newmint" : 0.00000000, "stake" : 0.00000000, "blocks" : 0, "timeoffset" : 0, "moneysupply" : 0.00000000, "connections" : 0, "proxy" : "", "ip" : "0.0.0.0", "difficulty" : {
In debug.log I have trying connection ip_PC1:xxxxx lastseen=0.9hrs connection timeout trying connection ip_PC1:xxxxx lastseen=0.9hrs connection timeout trying connection ip_PC1:xxxxx lastseen=0.9hrs connection timeout I don't know if i need to configure port forward in VM or my internet box.
