架构设计：

服务用户（和用户行为有关）

• 捕获用户输入、展示处理结果
• 自己相当于 View，背后有对应的 Controller/Model
• 核心的有：查账、转账，账号系统

服务自己（和用户行为无关，启动软件就自动运行）

• 自己就是一个服务（goroutine），以及与之关联的 .P2P、Mempool 也是服务
• 启动时偷偷做事，如同步区块数据（和链有关）
• 核心的有：同步块数据、同步交易数据

derod 
DERO : A secure, private blockchain with smart-contracts

Usage:
  derod [--help] [--version] [--testnet] [--debug]  [--sync-node] [--boltdb | --badgerdb] [--disable-checkpoints] [--socks-proxy=<socks_ip:port>] [--data-dir=<directory>] [--p2p-bind=<0.0.0.0:18089>] [--add-exclusive-node=<ip:port>]... [--add-priority-node=<ip:port>]...      [--min-peers=<11>] [--rpc-bind=<127.0.0.1:9999>] [--lowcpuram] [--mining-address=<wallet_address>] [--mining-threads=<cpu_num>] [--node-tag=<unique name>]
  derod -h | --help
  derod --version

Options:
  -h --help     Show this screen.
  --version     Show version.
  --testnet      Run in testnet mode.
  --debug       Debug mode enabled, print log messages
  --boltdb      Use boltdb as backend  (default on 64 bit systems)
  --badgerdb    Use Badgerdb as backend (default on 32 bit systems)
  --disable-checkpoints  Disable checkpoints, work in truly async, slow mode 1 block at a time
  --socks-proxy=<socks_ip:port>  Use a proxy to connect to network.
  --data-dir=<directory>    Store blockchain data at this location
  --rpc-bind=<127.0.0.1:9999>    RPC listens on this ip:port
  --p2p-bind=<0.0.0.0:18089>    p2p server listens on this ip:port, specify port 0 to disable listening server
  --add-exclusive-node=<ip:port>    Connect to specific peer only 
  --add-priority-node=<ip:port>    Maintain persistant connection to specified peer
  --sync-node       Sync node automatically with the seeds nodes. This option is for rare use.
  --min-peers=<11>      Number of connections the daemon tries to maintain  
  --lowcpuram          Disables some RAM consuming sections (deactivates mining/ultra compact protocol etc).
  --mining-address=<wallet_address>         This address is rewarded when a block is mined sucessfully
  --mining-threads=<cpu_num>         Number of CPU threads for mining
  --node-tag=<unique name>    Unique name of node, visible to everyone

架构设计：

启动、管理服务（本身是 for 死循环，一并启动管理 Blockchain、Mempool、P2P、RPC、Store 等其它服务）

命令处理、核心业务层（解析输入命令，调用对应服务进行处理）
