比特币BitCoin源代码

所有虚拟货币的鼻祖，源代码值得详读. /** CCoinsView that brings transactions from a memorypool into view. It does not check for spendings by memory pool transactions. */ CCoinsViewMemPool::CCoinsViewMemPool(CCoinsView &baseIn, CTxMemPool &mempoolIn) : CCoinsViewBacked(baseIn), mempool(mempoolIn) { } bool CCoinsViewMemPool::GetCoins(const uint256 &txid, CCoins &coins) { if (base->GetCoins(txid, coins)) return true; if (mempool.exists(txid)) { const CTransaction &tx = mempool.lookup(txid); coins = CCoins(tx, MEMPOOL_HEIGHT); return true; } return false; }
