我发现这个错误（例如错误：ReadBlockFromDisk:CBlockDiskPos（nFile=0，nPos=8）的块头中的错误）发生在pow.cpp中的checkproof函数中，感谢您的建议。看来
-reindex使用启动比特币或比特币qt -reindex命令行选项。这将丢弃索引和 从头开始重建，但尽可能重用磁盘上的块 它们是可用的
经过太多的努力，我终于解决了这个问题： (一) 应设置为下限，如
consensus.powLimit = uint256S("00ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff");
genesis = CreateGenesisBlock(1519394018, 6446, 0x1f0fffff, 1, 1 * COIN);
// calculate Genesis Block
// Reset genesis
consensus.hashGenesisBlock = uint256S("0x");
std::cout << std::string("Begin calculating Mainnet Genesis Block:\n");
if (true && (genesis.GetHash(consensus) != consensus.hashGenesisBlock)) {
// LogPrintf("Calculating Mainnet Genesis Block:\n");
arith_uint256 hashTarget = arith_uint256().SetCompact(genesis.nBits);
uint256 hash;
genesis.nNonce = ArithToUint256(0);
while (UintToArith256(genesis.GetHash(consensus)) > hashTarget)
{
genesis.nNonce = ArithToUint256(UintToArith256(genesis.nNonce) + 1);
if (genesis.nNonce == ArithToUint256(arith_uint256(0)))
{
LogPrintf("NONCE WRAPPED, incrementing time");
std::cout << std::string("NONCE WRAPPED, incrementing time:\n");
++genesis.nTime;
}
if ((int)genesis.nNonce.GetUint64(0) % 10000 == 0)
{
std::cout << strNetworkID << " hashTarget: " << hashTarget.ToString() << " nonce: " << genesis.nNonce.ToString() << " time: " << genesis.nTime << " hash: " << genesis.GetHash(consensus).ToString().c_str() << "\r";
}
}
std::cout << "Mainnet ---\n";
std::cout << " nonce: " << genesis.nNonce.ToString() << "\n";
std::cout << " time: " << genesis.nTime << "\n";
std::cout << " hash: " << genesis.GetHash(consensus).ToString().c_str() << "\n";
std::cout << " merklehash: " << genesis.hashMerkleRoot.ToString().c_str() << "\n";
}
std::cout << std::string("Finished calculating Mainnet Genesis Block:\n");
static CBlock CreateGenesisBlock(const char* pszTimestamp, const CScript& genesisOutputScript, uint32_t nTime, uint32_t nNonce, uint32_t nBits, int32_t nVersion, const CAmount& genesisReward);
genesis.nNonce = nNonce;
assert(consensus.hashGenesisBlock == uint256S("0x0009b0d830d5e13f7a39dd6c30cae59ff95e1a4aa4fc22435dc1fcb92561cd8e"));

consensus.powLimitStart = uint256S("0000000fffffffffffffffffffffffffffffffffffffffffffffffffffffffff");
consensus.powLimitLegacy = uint256S("00000000ffffffffffffffffffffffffffffffffffffffffffffffffffffffff");
我希望这会有所帮助。在
mainGetHash（）GetPoWHash（）consensus.hashGenesisBlock=uint256S（“0x”）；
std:：cout hashTarget）/-->这里是GetPoWHash（）！！
{
++genesis.nNonce；
如果（genesis.nNonce==0）
{
LogPrintf（“NONCE WRAPPED，incrementing time”）；
std:：coutFreddyJS，genesis.GetPoWHash（）
对litecoin很有效，哈希值与我使用GenesisH0得到的值匹配。但不幸的是，它在我正在测试的另一个硬币上不起作用，在编译时出现错误。有什么想法吗
错误：调用“CBlock:：GetPoWHash（）”时没有匹配的函数。
经过一些挖掘，代码与litecoin不同。在validation.cpp中：
// Check the header
if (!CheckProofOfWork(block.GetPoWHash(nHeight), block.nBits, consensusParams))
return error("ReadBlockFromDisk: Errors in block header at %s, %d", pos.ToString(), nHeight);
GetPoWHash（nHeight）
vsGetPoWHash（）
在litecoin中。你解决了吗？我有同样的问题，我在这里遇到了同样的问题。虽然此链接可以回答问题，但最好在此处包含答案的基本部分，并提供链接以供参考。如果链接页面发生更改，则仅链接的答案可能无效。-链接也没有解释问题的内容根本问题的原因是。我在玩groestlcoin的代码时遇到了这个问题，在重新设置代码中的变量（如nGenesisBlockRewardCoin以及consensus.HashGenesBlock和genesis.hashMerkleRoot）后遇到了这个问题。我试图启动一个全新的链，但最终遇到了这个问题。但对问题的本质是，很明显，链和/或钱包在某个点上已损坏，-reindex或-reindex-chainstate（由debug.log提出）参数解决了这个问题。这是一个临时解决方案。@Bedriozguler您好，我遇到了同样的OP问题，添加-reindex似乎至少让我迈出了下一步，但现在debug.log连续写入消息“检测到潜在的过时提示，将尝试使用额外的出站对等”，你知道为什么吗？那么，你上一次评论的基本解决方案是什么？@leegody你可能想查看比特币github:[net]上的这篇文章，跳过regtest中的过时提示检查#12484（），以及故意不与对等方连接时的“检测到的潜在过时提示”35;11608（）我不确定这两个问题线程是否对您的案例有帮助，但值得检查，也许您可以看到一些对您有帮助的东西。非常感谢！！我现在正在尝试克隆litecoin的最新源代码，所以我今天将对此进行测试，并将向您发送消息。请添加我skype:leegodskypeTested，但是，嗯…我仍然有这个错误。-------2018-02-26 04:50:02错误：ReadBlockFromDisk:CBlockDiskPos的块头错误（nFile=0，nPos=8）2018-02-26 04:50:02***未能读取块2018-02-26 04:50:02错误：错误：发生了致命的内部错误，请参阅debug.log了解详细信息------因此我使用了@Hossein的genesis块生成代码，因为在CreateGenesisBlock中，genesis.nNonce=nNonce；定义如下。现在呢？…嗯…ParseHex（？）之后这个变量的值应该是多少const CScript genesisOutputScript=CScript（），所以它可能需要通过pow.cpp的“checkproofwork”函数的genesis valid check？检查。这段视频（以及本系列中的以下5段视频）对我帮助很大。它将回答我相信的大多数问题。它还告诉我如何创建ParseHex（）的值我宁愿使用比特币v0.16（今天发布）而不是litecoin代码库
