filecoin开发网络使用

3.1 辅助资源

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

go-filecoin swarm peers 查看已经连接的节点

3.2.2 获取Mock FIL用于测试

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 矿工操作

3.2.3.1 存储矿工

  • 创建存储矿工示例，需要等待1分钟左右
    • 抵押10个扇区的存储空间（当前默认每个扇区256MiB）
    • 支付100个FIL为担保
    • gas价格为0
    • 限制gas消耗最大为1000个FIL 
      waynewyang:filecoin waynewyang$ go-filecoin miner create 10 100 --price=0 --limit=1000 --peerid `go-filecoin id | jq -r '.ID'`
fcqjge872spqrgtm8dhlndjgfhhuxzx0y3ujvxxsl //所返回的就是矿工地址minerAddress
  • 启动挖矿 
    waynewyang:filecoin waynewyang$ go-filecoin mining start
Started mining
    • 收益之一: 启动挖矿之后就可以参与挖区块奖励
      • 查询区块头 
        waynewyang:go-filecoin waynewyang$ go-filecoin chain head
[{"/":"zDPWYqFD2mBqLx7bwQNdeVoMxj6SC5HxzorZAoXpT6xjaythnENw"}]

  • 收益之二：创建报价单ask
    • 获取矿工地址 
      export MINER_ADDR=`go-filecoin config mining.minerAddress | tr -d \"`
    • 设置矿机Owner 
      export MINER_OWNER_ADDR=`go-filecoin miner owner $MINER_ADDR`
    • 创建报价单，价格0.000000001 FIL/byte/block, 交易费0，gas限制1000，提供2880个block空间存储 
      go-filecoin miner set-price --from=$MINER_OWNER_ADDR --miner=$MINER_ADDR --price=0 --limit=1000 0.000000001 2880 # output: CID of the ask
      发布报价单，需要打包进去区块 
      waynewyang:filecoin waynewyang$ go-filecoin miner set-price --from=$MINER_OWNER_ADDR --miner=$MINER_ADDR --price=0 --limit=1000 0.000000001 15315

    • 获取所有矿工的报价信息 
      go-filecoin client list-asks --enc=json | jq
      现在默认是只要客户出价高于矿工报价，默认接受交易。
  • 停止挖矿 
    go-filecoin mining stop
rm -rf ~/.filecoin  //删除filecoin矿工实例，区块同步也被删除，再次实例化，需要再次同步区块

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。

3.2.4 客户操作

3.2.4.1 存储客户

<data> CID of the imported data that you want to store
<ask> ID of the ask, also from list-asks (usually 0)
<duration> 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-filecoin client query-storage-deal < dealID >
  • 检索 
    go-filecoin retrieval-client retrieve-piece < minerAddress >  < CID >

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，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。
