架构

分为五个部分：

• 区块链（核心部分，其中又以区块、交易为重点）

• API/客户端/服务端（通过RPC交互）

• 网络传输（一般就是P2P）

• 数据存储（运用数据库，保存、管理数据）

• 数学/密码学

模块间调用

模块之间，可通过创建其关联对象进行互相调用。

API/客户端 - 调用 chain::Chain、p2p::Peers、pool::TransactionPool、pool::BlockChain、store::Store

区块链 - 调用 store::ChainStore（store::Store）、ChainAdapter、PMMRBackend（PMMR）

网络传输 - 调用 grin_store::Store，自调用 ChainAdapter、NetAdapter

交易池 - 调用 BlockChain、PoolAdapter

其它模块之间事件处理 - NetToChainAdapter（p2p::ChainAdapter）、ChainToPoolAndNetAdapter（chain::ChainAdapter）、PoolToNetAdapter（pool::PoolAdapter）、PoolToChainAdapter（pool::BlockChain）

目录结构

After checking out grin, building and using, these are the folders you'll have:

• api

  Code for ApiEndpoints accessible over REST.

• chain

  The blockchain implementation. Accepts a block (see pipe.rs) and adds it to the chain, or reject it.

• config

  Code for handling configuration.

• core

  All core types: Hash, Block, Input, Output, and how to serialize them. Core mining algorithm, and more.

• doc

  All documentation.

• servers

  Many parts (adapters, lib, miner, seed, server, sync, types) that the grin server needs, including mining server.

• keychain

  Code for working safely with keys and doing blinding.

• p2p

  All peer to peer connection and protocol-related logic (handshake, block propagation, etc.).

• pool

  Code for the transaction pool implementation.

• server

  A folder you're supposed to create , before starting your server: cd to project root; mkdir server; cd server; grin server start (or run) and it will create a subfolder .grin

  • .grin
    • chain
      • a database with the blockchain blocks and related information
    • peers
      • a database with the list of Grin peers you're connected to
    • txhashset
      • contains folders kernel, rangeproof and output that each have a pmmr_dat.bin

• src

  Code for the grin binary.

• store

  Data store - Grin uses near-zero-cost Rust wrapper around LMDB, key-value embedded data store.

• target

  Where the grin binary ends up, after the compile and build process finishes. In case of trouble, see troubleshooting

• util

  Low-level rust utilities.

• wallet

  Simple command line wallet implementation. Will generate:

  • wallet_data
    • a database storing your "outputs", that once confirmed and matured, can be spent with thegrin wallet sendcommand. (locally created, _not _in git)
  • wallet.seed
    • your secret wallet seed. (locally created, _not _in git)
