    I have a brain hole idea. Do you remember the original idea of protocol lab? Let the spare storage of the world contribute its own storage as a node, but so far this difficulty increases the hardware requirements. There are several main factors affecting the family miners: 1. Hardware volume problem. At present, most small bulk miners, including the mining pool, are using a large volume of servers to dig, occupying a large space. 2. The problem of heat dissipation and noise, the noise of large server fan is very unbearable, and the cost of heat dissipation is also very high. In order to dissipate heat, air conditioners may be used. 3. Network problems and power failure are the pain of many miners.

    After my own consideration, I think there may be a solution to these problems! First, to solve the first problem, I think the CPU can use the processor of the notebook to be the most powerful CPU, and the graphics card can use the MXM notebook graphics card motherboard to customize two-way, so that the space is reduced and can be installed with an iron box (refer to the picture). The customized memory slot can expand up to 8 slots and double m.2 slots. The double-layer iron box is put into the hard disk for hot plug. 2. Let's say that split water-cooled CPU and GPU for heat dissipation use full coverage customized cold head and customized water pump circulating cold exhaust. More than ten machines can be put down in the cabinet, and a large-scale overall cold exhaust cooling and fan can be installed behind the cabinet. 3. When the power is cut off, UPS can be used to equip the generator. The network can customize the 5g flow card of the main board to automatically switch the 5g flow card when there is no network. It is believed that the 5g universal network speed will be very fast in the future without worrying about the network speed. The above is my personal point of view. I hope that some deficiencies can be pointed out and joint research can contribute to the cause of filecoin

    【Filecoin挖矿日记—第一篇】
    #请关注加入本微信,记得点击好看#
    🟡测试硬件🟡
    本次测试用的是二手戴尔服务器,英特尔GTX 1080Ti,128GB内存
    🟣开始挖矿前🟣
    请参照官网把各个需要依赖的库安装好,最好采用Ubuntu系统。另外需要配置golang和Rust国内的加速镜像库,这样加快安装编译过程。
    例如🔜

    echo "GOPROXY=https://goproxy.cn
    " >> ~/.profile && source ~/.profile

    export RUSTUP_DIST_SERVER=https://mirrors.ustc.edu.cn/rust-static
    export RUSTUP_UPDATE_ROOT=https://mirrors.ustc.edu.cn/rust-static/rustup

    🟣挖矿过程,资源消耗🟣
    filecoin挖矿过程,分Packing,Unseal这个过程是,生成随机数文件,并进行打包,然后进行封装扇区。filecoin可以在配置文件config.修改,你想并行处理多少个任务,这里对CPU资源消耗较大,也要占用内存资源。
    📓Filecoin/IPFS挖矿日记-第二篇📓
    🟣完成一个前期挖矿流程需要多长时间?🟣
    filecoin挖矿流程分,前期的生成随机数文件,32GB的文件生成需要5到6分钟,这个主要看你的CPU核心数和能力。后面要把文件分片,分片过程会消耗大量CPU资源。然后开始封装扇区,接着开始准备提交数据,这几个过程对CPU要求都很大。下面开始生成proof证明,这里才会用到显卡加速,10GB的显存显卡,基本消耗20%左右。整个32GB数据完成整个流程需要5个多小时,还是看CPU的性能。最后定时提交fPOST提交到链上,这里占用内存会比较大,达到40多GB。

    📜Filecoin挖矿日记第三篇📜
    🟣如何设置显卡,并正常运行呢?🟣
    Filecoin挖矿只支持英伟达显卡,所以需要到英伟达官网安装显卡驱动。另外需要设置环境变量,挖矿程序才能识别显卡。
    所以我们修改/etc/profile文件,加入变量

    BELLMAN_CUSTOM_GPU=“”

    保存后,source /etc/profile,即可生效。

    📜Filecoin挖矿日记第四篇📜
    🟣代码层面分析挖矿全过程🟣
    当我们执行生成sector过程后,挖矿程序先会生成随机数文件,然后生成订单信息,2020-02-04T11:46:53.352+0800 INFO sectors sealing/garbage.go:40 Pledge 47, contains []
    这个日志信息显示开始封装扇区
    分装扇区需要对数据进行分片

    2020-02-04T11:52:49.896 INFO filecoin_proofs::pieces > verifying 64 pieces

    2020-02-04T11:54:45.380+0800 INFO sectors sealing/garbage.go:100 Deals for sector 47:

    2020-02-04T12:03:53.770+0800 INFO sectors sealing/sealing.go:124 Start sealing 47

    数据扇区封装完毕后,开始准备提交链上的过程

    2020-02-04T12:03:53.830 INFO filecoin::proofs::api > seal_pre_commit: start
    2020-02-04T12:03:53.831 INFO filecoin_proofs::api::seal > seal_pre_commit: start

    后面需要将生成DRG的数据结构

    2020-02-04T12:07:58.133 INFO storage_proofs::stacked::proof > encoding 256 windows
    2020-02-04T12:40:33.345 INFO storage_proofs::stacked::proof > building column hashes
    2020-02-04T14:15:04.093 INFO storage_proofs::stacked::proof > building tree_q
    数据格式转换完毕后,进行提交

    2020-02-04T15:34:31.581 INFO filecoin::proofs::api > seal_commit: start
    2020-02-04T15:34:31.581 INFO filecoin_proofs::api::seal > seal_commit:start

    提交完毕后,即开始生成共识证明过程

    2020-02-04T15:51:29.357 INFO storage_proofs::compound_proof > vanilla_proof:finish

    2020-02-04T15:51:37.969 INFO storage_proofs::compound_proof > snark_proof:start

    It shouldn't be a significant centralization risk. The costs of buying your own GPUs or starting a new outsourced proving service will be pretty low. Even if many people decide to use third-party provers, there should be a competitive and well-distributed market.
