c++ - 比特币最近这么热，有人分析过其源码么？

Question

从github上clone了bitcoin的源码，看src文件里大多是cpp文件，应该是用c++写的，但是没找到main函数，如果我想在windows上编译运行，如何做呢？有人分析过源码么？

The author added "Chapter Negative Chapter 2, Abridged Version" on 2013-11-22 and provided a source code:

function mine()
{
    while(true)
    {
        longestChain = getLongestValidChain()

        -- A number that changes every time, so that you don't waste time
        -- trying to calculate a valid blockHash with the same input.
        nonce = getNewNonce()

        currentTXs = getUnconfirmedTransactionsFromNetwork()

        newBlock = getNewBlock(longestChain, currentTX, nonce)

        -- http://en.wikipedia.org/wiki/SHA-2
        -- and this is what all the "mining machines" are doing.
        blockHash = sha256(newBlock)

        if(meetReqirements(blockHash))
        {
            broadcast(newBlock)
            -- Now the height of the block chain is incremented by 1
            -- (if the new block is accepted by other peers),
            -- and all the TXs in the new block are "confirmed"
        }
    }
}
////////////////////////////////////////////////////// ///////////////
function sendBTC(amount)
{
    sourceTXs = pickConfirmedTransactionsToBeSpent(amount)
    tx = generateTX(sourceTXs, targetAddrs, amount, fee)
    signedTx = sign(tx, privateKeysOfAllInputAddress)
    broadcast(signedTx)
}

Although there is no analysis now, please wait for the author's update.

It is a pity that the author's reply was: "I have no intention to continue writing."

Answer 2

The MAIN function is in bitcoinGUI.cpp or bitcoind.cpp. Check DOC/BUILD-WIN.MD for compilation methods
