FileChain

文件链试图实现一个简单的文件共享链

该项目区块链的部分基本是对 BTCD 项目的 fork，并在其基础上加入了文件共享的功能。

文件共享的灵感主要来源于 IPFS 项目,对其做了一些简化

文件传输 P2P 协议基于 libp2p 项目

该项目还在非常早期的阶段，一切都有可能更改

Overview

btcd is a full-node bitcoin implementation written in Go.

The default options are sane for most users. This means btcd will work 'out of the box' for most users. However, there are also a wide variety of flags that can be used to control it.

The following section provides a usage overview which enumerates the flags. An interesting point to note is that the long form of all of these options (except -C) can be specified in a configuration file that is automatically parsed when btcd starts up. By default, the configuration file is located at ~/.btcd/btcd.conf on POSIX-style operating systems and %LOCALAPPDATA%\btcd\btcd.conf on Windows. The -C (--configfile) flag, as shown below, can be used to override this location.

Usage:
