filecoin开发网络使用

辅助资源

使用

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

waynewyang:filecoin waynewyang$ go-filecoin swarm peers /ip4/115.238.154.84/tcp/19109/ipfs/Qmb6ZYi7GLFAje3UekGZ2LZymck7RVHKSKb1bhPzzPTQkm /ip4/115.238.154.84/tcp/41187/ipfs/QmZ9UHdU2fwDN7emWW8AeaUdkF9fT7RwJrnbbdcQFUq9X6 /ip4/123.134.67.81/tcp/6000/ipfs/QmccrEQsauwge4BZQeN1jBtFyd7dnTi4pSDvkikMWaFccw /ip4/123.134.67.82/tcp/6000/ipfs/QmWuA1AW4qDqztDrwo2pBgT2au67BJbGtEzWRufbc8isgn /ip4/123.134.67.83/tcp/6000/ipfs/QmbPCabGcngs3bCgMK8dC3w9pjoyPd1NFyDhbkgLyT2eJ7 /ip4/123.134.67.85/tcp/6000/ipfs/QmUqSSZrwfSUU3vfw7D1UyKaLvEv1Ykcvx3ntvSXWaA7kj /ip4/123.134.67.86/tcp/6000/ipfs/QmPrz2z764AVaHivM7iX2JqRw5EdE3jcZTrjwVxS4VukyK /ip4/123.134.67.87/tcp/6000/ipfs/QmTxVFq3u7qPxsXFQdoyqPrdh6meW6JBGkSJ8HJXAiMUfh /ip4/123.134.67.88/tcp/6000/ipfs/QmXAVRPYu57XDwJHszn9U9x1KtTwPsJBaS1mTdNZzAQVyQ /ip4/123.134.67.89/tcp/6000/ipfs/Qmc5umx9R3bpD5VxvUmfyLoDz5wtVT43p5xjSEmTe26qTD


> go-filecoin ping peerID 确认连通性

- 给你的filecoin Node设置昵称

waynewyang:filecoin waynewyang$ go-filecoin config heartbeat.nickname "wwwarsyuncom" "wwwarsyuncom" waynewyang:filecoin waynewyang$ go-filecoin config heartbeat.nickname "wwwarsyuncom"


- 激活节点

go-filecoin config heartbeat.beatTarget "/dns4/stats-infra.kittyhawk.wtf/tcp/8080/ipfs/QmUWmZnpZb6xFryNDeNU7KcJ1Af5oHy7fB9npU67sseEjR"


> 在 https://stats.kittyhawk.wtf/ 查看filecoin网络,节点已经激活

#### 获取Mock FIL用于测试<a name="从faucet中获取mock代币"></a>

> 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。

####   矿工操作<a name="矿工操作"></a>
####  存储矿工<a name="存储矿工"></a>
- 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"}]


> 查询具体区块信息

go-filecoin show block

waynewyang:go-filecoin waynewyang$ go-filecoin show block zDPWYqFD2mBqLx7bwQNdeVoMxj6SC5HxzorZAoXpT6xjaythnENw Block Details Miner: fcq0y72meekgwnvchwml0uzx759q25nk0rqc47ret Weight: 293567.552 Height: 10787 Nonce: 0


- 收益之二:创建报价单ask

1) 获取矿工地址 export MINER_ADDR=go-filecoin config mining.minerAddress | tr -d \"

2) 设置矿机Owner export MINER_OWNER_ADDR=go-filecoin miner owner $MINER_ADDR

3) 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 Set price for miner fcqjge872spqrgtm8dhlndjgfhhuxzx0y3ujvxxsl to 0.000000001. Published ask, cid: zDPWYqFCxL3VW3xzmHhCBqPTvhoQa53pn6DzV3uY23jNL76za1Vt. Ask confirmed on chain in block: zDPWYqFD7wjnj74sdB9HqupDmWmpPPEvygB14Pbo6rQC7ho2687D.

4) 查询区块信息(第三步中是zDPWYqFD7wjnj74sdB9HqupDmWmpPPEvygB14Pbo6rQC7ho2687D)可以找到对应报价单信息

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 ``` #### 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 > ``` ### filecoin合约 #### 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](https://learnblockchain.cn/2017/11/20/whatiseth/)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。 #### 智能合约 > 暂未发现支持,在后面的深入分析中会继续跟进。 ### 单机运行多个filecoin节点 #### 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。 #### 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。 [深入浅出区块链](https://learnblockchain.cn/) - 系统学习区块链,打造最好的区块链技术博客
