比特币源码研读之一
——区块链研习社 《比特币源码研读班》
一看文件夹结构 和 github编译依赖，分析的依赖库
src
compat //工作台代码 base58等
config
consensus //交易相关 merkle树
crypto //加解密（aes sha）
leveldb //文件数据库 leveldb
obj
obj-test
policy //背书
primitives //区块和交易的数据结构
qt //ui框架 qt
rpc //rpc 远程进程调用
script //交易脚本
secp256k1 //椭圆曲线
support
test //测试代码
univalue
wallet //钱包相关
zmq //消息队列库 zmq
| Library | Purpose | Description |
|---|---|---|
| libssl | Crypto | Random Number Generation, Elliptic Curve Cryptography |
| libboost | Utility | Library for threading, data structures, etc |
| libevent | Networking | OS independent asynchronous networking |
| miniupnpc | UPnP Support | Firewall-jumping support |
| libdb4.8 | Berkeley DB | Wallet storage (only needed when wallet enabled) |
| qt | GUI | GUI toolkit (only needed when GUI enabled) |
| protobuf | Payments in GUI | Data interchange format used for payment protocol (only needed when GUI enabled) |
| libqrencode | QR codes in GUI | Optional for generating QR codes (only needed when GUI enabled) |
| univalue | Utility | JSON parsing and encoding (bundled version will be used unless --with-system-univalue passed to configure) |
| libzmq3 | ZMQ notification | Optional, allows generating ZMQ notifications (requires ZMQ version >= 4.x) |
二 看main.cpp文件 (src/bitcoind.cpp)
int main(int argc, char* argv[])
{
SetupEnvironment(); //设置运行环境变量
// Connect bitcoind signal handlers
noui_connect(); //连接信号和槽
//根据输入的argc argv 参数初始化程序
return (AppInit(argc, argv) ? EXIT_SUCCESS : EXIT_FAILURE);
}
三 附main函数的结构图
