Ren Protocol

“暗池交易的主要优势在于，进行大宗交易的机构投资者可以在寻找买家和卖家时不会曝光。可以防止影响到整个市场，避免贬值。

Republic Protocol系统依靠精心设计的激励系统来保证玩家遵守规则。RenEx“Dark Nodes”运行撮合引擎来保证暗池的运行，同时多个暗池的存在将减轻交易对手的风险。为了防止恶意攻击，规定网络节点（Darknodes）必须支付100000个Ren，这个也就是Republic Protocol的Token。

Akash DeCloud

根据官网介绍：Akash正在建立一个虚拟市场，让个人和组织实现无摩擦的云算力买卖的Airbnb市场：Airbnb平台能让用户出租闲置的房子，Akash平台则让用户出租闲置的算力。双方的直接接触大大拓展了已有的市场，让闲置的资源得以利用——出租方获得收益，租户获得更简便的体验。

目前世界上有大约840万个数据中心，其中85%服务器容量未被充分利用，Akash的去中心化云计算市场将如何彻底改变和重新定义云市场。

akash肯定有自己的优势：

  • **去中心化：**Akash提供可信的执行环境，网络启动后，即使团队停止开发，用户仍然能正常使用Askah。
  • **无需许可：**只需要按照标准接入市场，人人可自由出借算力获取收益，人人可按需借用算力。
  • **成本更低：**Akash用户直接出价，供应商竞价获取该任务。买卖直接受供需关系影响，能提供更合理的价格。根据测试数据，Akash的云计算成本比现有市场提供商（AWS、谷歌云、微软Azure和阿里云）低10倍。

简而言之就是Akash是一个去中心化的云服务商，可以帮助我们以低成本像在AWS上部署应用一样部署一个去中心化应用。

整个教程大概分为编译构建源码、创建上传docker镜像、akash部署环境准备、部署Ren Protocol几部分。

编译构建源码

  1. 我们从Ren Protocol拉取代码

    git clone https://github.com/renproject/bridge.git

    输出如下

    ➜  github git clone https://github.com.cnpmjs.org/renproject/bridge.git
Cloning into 'bridge'...
remote: Enumerating objects: 40, done.
remote: Counting objects: 100% (40/40), done.
remote: Compressing objects: 100% (26/26), done.
remote: Total 1354 (delta 16), reused 26 (delta 13), pack-reused 1314
Receiving objects: 100% (1354/1354), 85.64 MiB | 10.25 MiB/s, done.
Resolving deltas: 100% (886/886), done.

  2. 注册自己的firebase账号并获取Key之后设置变量

    export REACT_APP_FB_KEY="YOUR_KEY_HERE"

  3. 安装依赖

    cd bridge && yarn install

  4. 运行

    yarn start

    之后访问 http://localhost:3000/

  5. 打包

    yarn build

    输出如下

    ➜  bridge git:(master) ✗ yarn build
yarn run v1.22.10
$ CI=false REACT_APP_VERSION=$npm_package_version react-scripts --max_old_space_size=4096 build

You may serve it with a static server:

  yarn global add serve
  serve -s build

创建docker镜像

  1. 创建Dockerfile文件

    vi Dockerfile

    填入如下内容

    FROM nginx
ENV REACT_APP_FB_KEY="YOUR_KEY_HERE"
COPY build /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

  2. 生成docker镜像

    docker build . -t fishflyhuang/renprotocol:latest

    输出如下

    ➜  bridge git:(master) ✗ docker build . -t fishflyhuang/renprotocol:latest
Sending build context to Docker daemon  846.2MB
Step 1/5 : FROM nginx

  3. 查看docker镜像

    docker images

  4. 运行容器

    在3260端口后台运行

    docker run -d --name renprotocol -p 3260:80 --restart=unless-stopped fishflyhuang/renprotocol:latest

    通过 http://localhost:3260/ 访问

  5. 上传镜像

    docker push fishflyhuang/renprotocol:latest

    输出如下

    ➜  bridge git:(master) ✗ docker push fishflyhuang/renprotocol:latest
The push refers to repository [docker.io/fishflyhuang/renprotocol]

akash部署环境准备(Edgenet测试网)

安装钱包

这里使用的环境是ubuntu18.04

  1. 下载akash钱包程序

    wget https://github.com/ovrclk/akash/releases/download/v0.9.0-rc13/akash_0.9.0-rc13_linux_arm64.zip

  2. 解压

    tar -xvf akash_0.9.0-rc13_linux_arm64.zip

  3. 重命名目录

    mv akash_0.9.0-rc13_linux_arm64 akash

  4. 配置环境变量

    /work/akash/akash 为我们刚刚解压的路径

    编辑 /etc/profile 文件在最后加入一下内容

    export PATH=$PATH:/work/akash/akash

    之后运行

    akash version

    输出版本号

    v0.9.0-rc13

  5. 创建钱包地址

    这里需要预先准备一些变量， KEY_NAME 是自己设置的字符串，默认 alice

    export KEY_NAME=alice
export KEYRING_BACKEND=local

    生成钱包地址

    akash --keyring-backend "$KEYRING_BACKEND" keys add "$KEY_NAME"

    输出如下

    - name: alice
  type: local
  address: akash1cz87pqkad72gggrv3t7y2x9z56h9gqghlnx3j3
  pubkey: akashpub1addwnpepqtnydvj056gy64uuquldq5yx7mr8ncmn3ut59wwl9p83d8h2v4rtg5xa3vn
  mnemonic: ""
  threshold: 0
  pubkeys: []


**Important** write this mnemonic phrase in a safe place. It is the only way to recover your account if you ever forget your password.

town wolf margin parrot strong disease dance eyebrow inflict meadow crunch version tube elite interest movie uphold column shift fox excuse humble nest call

    address 就是我们生成的账户地址

    最后的那24个单词非常重要，是我们钱包的助记词，需要我们保存好，恢复导入钱包的时候需要

领取测试币

这里需要先设置几个常用的变量

export AKASH_NET="https://raw.githubusercontent.com/ovrclk/net/master/edgenet"
export AKASH_CHAIN_ID="$(curl -s "$AKASH_NET/chain-id.txt")"
exprot AKASH_NODE="$(curl -s "$AKASH_NET/rpc-nodes.txt" | shuf -n 1)"
export ACCOUNT_ADDRESS=akash1cz87pqkad72gggrv3t7y2x9z56h9gqghlnx3j3

AKASH_NET: 您要连接的网络的基本URL

AKASH_CHAIN_ID: 需要连接的链的ID

AKASH_NODE: 节点RPC地址

ACCOUNT_ADDRESS: 前面生成的钱包地址

运行命令查看领取测试币的水龙头地址

curl "$AKASH_NET/faucet-url.txt"

输出如下

https://akash.vitwit.com/faucet

在浏览器打开这个地址通过人机认证之后填入钱包地址确定，等待一会之后账户收到测试币，可以通过命令查看余额

akash --node "$AKASH_NODE" query bank balances "$ACCOUNT_ADDRESS"

输出如下

balances:
- amount: "135230674"
  denom: uakt
pagination:
  next_key: null
  total: "0"

akt的精度是6，所以余额应该是 135230674 uakt = 135 akt

部署Ren Protocol

  1. 根据应用部署教程配置 deploy.yml文件

    创建&编辑deploy.yml文件

    touch deploy.yml
vi deploy.yml

    加入以下内容

    ---
version: "2.0"

services:
  web:
    image: fishflyhuang/renprotocol
    expose:
      - port: 80
        as: 80

          denom: uakt
          amount: 1000

deployment:
  web:
    westcoast:
      profile: web
      count: 1

  2. 部署

    akash tx deployment create deploy.yml --from $KEY_NAME --node $AKASH_NODE --chain-id $AKASH_CHAIN_ID -y

    输出如下

    {

  ],
  "info": "",
  "gas_wanted": "200000",
  "gas_used": "53806",
  "tx": null,
  "timestamp": ""
}

  3. 查看刚刚部署的状态

    akash query market lease list --owner $ACCOUNT_ADDRESS --node $AKASH_NODE --state active

    输出如下

    - lease_id:
    dseq: "183906"
    gseq: 1
    oseq: 1
    owner: akash15rrya4ayu8yewh3d2agg552phtttpkghpd0paf
    provider: akash174hxdpuxsuys9qkauaf57ym5j8dm4secnz6jd7
  price:
    amount: "331"
    denom: uakt
  state: active
pagination:
  next_key: null
  total: "0"

    记录下前面的输出的几个变量备用

    export PROVIDER=akash174hxdpuxsuys9qkauaf57ym5j8dm4secnz6jd7
export DSEQ=183906
export OSEQ=1
export GSEQ=1

  4. 上传 Manifest

    akash provider send-manifest deploy.yml --node $AKASH_NODE --dseq $DSEQ --oseq $OSEQ --gseq $GSEQ --owner $ACCOUNT_ADDRESS --provider $PROVIDER

  5. 查看部署的具体信息

    akash provider lease-status --node $AKASH_NODE --dseq $DSEQ --oseq $OSEQ --gseq $GSEQ --provider $PROVIDER --owner $ACCOUNT_ADDRESS

    输出如下

    {
  "services": {
    "web": {
      "name": "web",
      "available": 0,
      "total": 1,
      "uris": [
        "c5fh0i0ietclnc6ush378isr5s.provider2.akashdev.net"
      ],
      "observed-generation": 0,
      "replicas": 0,
      "updated-replicas": 0,
      "ready-replicas": 0,
      "available-replicas": 0
    }
  },
  "forwarded-ports": {}
}

  6. 访问部署的应用

    http://c5fh0i0ietclnc6ush378isr5s.provider2.akashdev.net/

  7. 关闭部署

    akash tx deployment close --node $AKASH_NODE --chain-id $AKASH_CHAIN_ID --dseq $DSEQ --owner $ACCOUNT_ADDRESS --from $KEY_NAME -y

到这里部署全部完成。
