3.2 使用3.2.1 接入filecoin开发网络初始化filecoin资源目录
如果之前有运行过filecoin，想重新开始，需要删除filecoin资源，同时重新初始化是需要重新花时间同步开发网区块信息的。
rm-rf~/.filecoin
初始化资源目录，使用--devnet-user表示连接至开发网
waynewyang:Downloads waynewyang$ go-filecoin init --devnet-user --genesisfile=http://user.kittyhawk.wtf:8020/genesis.car
initializing filecoin node at ~/.filecoin
waynewyang:Downloads waynewyang$
启动filecoin进程，接入开发网
go-filecoin daemon
//如果开发者，需要接入nightly devnet，请设置环境变量后启动filecoin
env FIL_USE_SMALL_SECTORS=true go-filecoin daemon
检查连接性

3.2.2 获取Mock FIL用于测试Mock FIL用于矿工抵押；或者作为客户进行交易需要
注意：开发网目前运行的都是全节点，获取mock FIL需要建立在本地区块数据同步完成的基础上进行，必须同步完区块之后才能生效，根据个人机器配置情况，这需要较长一段时间。
go-filecoin message wait ${MESSAGE_CID} 本质上是转账交易，wiki上说明的是等待30s，但是这是在本地区块数据同步完成的基础上才行的。
笔者已提交建议给官方，在wiki上更为清晰地表述。

3.2.3.2 检索矿工暂未发现支持，目前可以自己的供应商（具体矿工）处获取；后面通过更深入的分析之后另行补充。
3.2.3.3 修复矿工修复矿工的概念是白皮书之后提出的，后面继续深入分析之后再另行补充。

下单
go-filecoin client propose-storage-deal
address of the miner from list-asks
CID of the imported data that you want to store
ID of the ask, also from list-asks (usually 0)
how long you want to store (in # of ~30sec blocks). For example, storing for 1 day (2 blocks/min * 60 min/hr * 24 hr/day) = 2880 blocks.
发送数据和支付
1 支付
1）支付到paych中
2）定期向矿工付款
2 数据
1）未密封完的数据称之为暂存区
2）密封完成后阶段性支付
3.2.4.2 检索客户现在是指定所对应的存储矿工进行检索，暂未发现更多支持，在后面的深入分析中会继续跟进。
查询订单状态，必须是密封，posted交易结束后才能查询
go-filecoinclientquery-storage-deal
检索
go-filecoin retrieval-client retrieve-piece
3.2.5 filecoin合约3.2.5.1 文件合约其实现在的创建存储矿工，以及矿工创建报价、存储客户提交订单存储，这些笔者认为属于filecoin文件合约的范畴。
与以太坊类似，以太坊抽象出了代币合约以及通用智能合约； 而filecoin则是抽象出了文件合约和通用智能合约。
3.2.5.2 智能合约暂未发现支持通用智能合约，在后面的深入分析中会继续跟进。
3.2.6 单机运行多个filecoin节点3.2.6.1 修改资源目录和服务端口的方式go-filecoin init的时候，通过 ‘--repodir=所指定资源目录路径’ 命令进行初始化目录资源，后面的其他命令同样需要所指定资源目录路径进行操作。
修改资源目录下的config.json文件，将默认的端口予以修改，避免与另外的本机实例相冲突。
3.2.6.2 容器部署方式可以打包成docker镜像，有兴趣的朋友可以自行尝试。
