Airchains能与celestia, Avail, EigenDa等DA层集成，在执行层方面，支持EVM,Cosmwasm和SVM。

近期Airchains启动了Station奖励计划，旨在激励和支持像开发人员在 Airchains 网络上构建出色的项目。

通过在 Airchains 网络上创建Station，您可以开始赚取积分并解锁令人难以置信的奖励！您建造的Station越多，您为生态系统带来的价值越多，您的奖励就越高。

本教程将教你如何创建Airchains的Cosmwasm Zk Rollup Station并赚取积分。

由于avail经常没水，我们选择eigenda作为da。

Cosmwasm Zk Rollup 可能遇到一些奇怪的无法解决的错误，建议创建EVM + Eigenda的station

配置要求
----

系统: Ubuntu 22.04

![](https://storage.googleapis.com/papyrus_images/b5fe77a603dc11c01f94fb79cd041bf07345bd432b3e4d7bfd6ae953580e1b0b.png)

安装依赖
----

    sudo apt-get update && apt-get install jq build-essential -y
    

### 安装go

    curl https://dl.google.com/go/go1.22.1.linux-amd64.tar.gz | sudo tar -C/usr/local -zxvf - ;
    cat <<'EOF' >>$HOME/.bashrc
    export GOROOT=/usr/local/go
    export GOPATH=$HOME/go
    export GO111MODULE=on
    export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
    EOF
    source $HOME/.bashrc
    

这里我们选择创建Cosmwasm Zk Rollup

下载GitHub 库
----------

    cd
    git clone https://github.com/airchains-network/wasm-station.git
    git clone https://github.com/airchains-network/tracks.git
    

设置Wasm Station
--------------

    cd wasm-station
    go mod tidy
    

    /bin/bash ./scripts/local-setup.sh
    

这里需要等待一段时间。

成功后你会看到这样的内容

![等待一段时间后，你会看到类似这样的内容](https://storage.googleapis.com/papyrus_images/e13f9460d0a7d9961a775963c071ecf9b91f3cebcf253d8ddea4b6c7220d6283.png)

等待一段时间后，你会看到类似这样的内容

### 运行wasmstation

    sudo tee <<EOF >/dev/null /etc/systemd/system/wasmstationd.service
    [Unit]
    Description=wasmstationd
    After=network.target
    [Service]
    User=$USER
    ExecStart=$HOME/wasm-station/build/wasmstationd start --api.enable
    Restart=always
    RestartSec=3
    LimitNOFILE=10000
    [Install]
    WantedBy=multi-user.target
    EOF
    
    sudo systemctl daemon-reload && \
    sudo systemctl enable wasmstationd && \
    sudo systemctl start wasmstationd
    

查看日志

    sudo journalctl -u wasmstationd -f
    

设置DA
----

### **下载eigenlayer cli**

    cd
    wget https://github.com/airchains-network/tracks/releases/download/v0.0.2/eigenlayer
    sudo chmod +x eigenlayer
    sudo mv eigenlayer /usr/local/bin/eigenlayer
    

### **创建key**

    eigenlayer operator keys create  -i=true --key-type ecdsa 你的钱包名 
    

**保存好出现的私钥，输入:q 退出**

**记录好出现的Public Key hex**，后面要用

![这里的Public Key hex后面有用](https://storage.googleapis.com/papyrus_images/6b19de7c722ce29a5c541601cbbafaf32b51da87c0b36e3aab5d0f316478f943.png)

这里的Public Key hex后面有用

设置Tracks
--------

删除所有旧数据

    sudo rm -rf ~/.tracks
    

下载依赖

    cd $HOME/tracks
    go mod tidy
    

### 初始化sequencer

    go run cmd/main.go init --daRpc "disperser-holesky.eigenda.xyz" --daKey "上面的Public Key hex" --daType "eigen" --moniker "节点名" --stationRpc "http://127.0.0.1:26657" --stationAPI "http://127.0.0.1:1317" --stationType "wasm"
    

成功后,能看到如下

    [2024-06-11 09:50:08] » Track initialization successful
    

### 创建**airchains** 地址

    go run cmd/main.go keys junction --accountName airchains地址名 --accountPath $HOME/.tracks/junction-accounts/keys
    

**注意保存这里显示的助记词**，否则之后无法恢复。**这里也会显示air开头的地址，后面有用**

### 领水

在discord的Switchyard-faucet频道发送

    $faucet air开头的地址领水
    

如果discord水龙头没水了，可以试试这个

](https://airchains.faucetme.pro/)

### 初始化prover

    go run cmd/main.go prover v1WASM
    

获取bootstrapNode值

    nodeid=$(grep "node_id" ~/.tracks/config/sequencer.toml | awk -F '"' '{print $2}')
    ip=$(curl -s4 ifconfig.me/ip)
    bootstrapNode=/ip4/$ip/tcp/2300/p2p/$nodeid
    echo $bootstrapNode
    

最后显示的的应该类似

    /ip4/<你服务器的ip>/tcp/2300/p2p/你的nodeid
    

这就是你的bootstrapNode值

### 创建station

    go run cmd/main.go create-station --accountName airchains地址名 --accountPath $HOME/.tracks/junction-accounts/keys --jsonRPC "https://junction-testnet-rpc.synergynodes.com/" --info "WASM Track" --tracks 刚刚air开头的地址 --bootstrapNode "刚刚显示的bootstrapNode"
    

**等待一段时间后**，会显示如下

### 修改代码默认的gas price

    sed -i 's/gasFees := fmt.Sprintf("%damf", gas)/gasFees := fmt.Sprintf("%damf", 2*gas)/' "$HOME/tracks/junction/verifyPod.go"
    sed -i 's/gasFees := fmt.Sprintf("%damf", gas)/gasFees := fmt.Sprintf("%damf", 2*gas)/' "$HOME/tracks/junction/validateVRF.go"
    sed -i 's/gasFees := fmt.Sprintf("%damf", gas)/gasFees := fmt.Sprintf("%damf", 3*gas)/' "$HOME/tracks/junction/submitPod.go"
    

### 启动station

    sudo tee /etc/systemd/system/stationd.service > /dev/null << EOF
    [Unit]
    Description=station track service
    After=network-online.target
    [Service]
    User=$USER
    WorkingDirectory=$HOME/tracks/
    ExecStart=$(which go) run cmd/main.go start
    Restart=always
    RestartSec=3
    LimitNOFILE=65535
    [Install]
    WantedBy=multi-user.target
    EOF
    sudo systemctl daemon-reload
    sudo systemctl enable stationd
    sudo systemctl restart stationd
    

### 查看station日志

    sudo journalctl -u stationd -f -o cat
    

Ctrl +c 退出查看日志

刷TX
---

创建脚本

    cd
    addr=$($HOME/wasm-station/build/wasmstationd keys show node --keyring-backend test -a)
    sudo tee spam.sh > /dev/null << EOF
    #!/bin/bash
    
    while true; do
      $HOME/wasm-station/build/wasmstationd tx bank send node ${addr} 1stake --from node --chain-id station-1 --keyring-backend test -y 
      sleep 6  # Add a sleep to avoid overwhelming the system or network
    done
    EOF
    

后台运行刷tx脚本

    nohup bash spam.sh &
    

看日志，正常是这样。成功之后，你会在rollup中每6秒发一笔交易。

`cat nohup.out`

    code: 0
    codespace: ""
    data: ""
    events: []
    gas_used: "0"
    gas_wanted: "0"
    height: "0"
    info: ""
    logs: []
    raw_log: ""
    timestamp: ""
    tx: null
    txhash: F2F9C6911D3D48C98CAC47773E0B7B4C8E9AD23BFD10692177BA5C8C69980A3B
    code: 0
    codespace: ""
    data: ""
    events: []
    gas_used: "0"
    gas_wanted: "0"

    txhash: ACB167A5B5E806B59497EA49B825106E1AB4C8FA7808AA89A726F4109E4E00FB
    

再次查看station日志

    sudo journalctl -u stationd -f -o cat
    

正常会看到这样的日志

![正常的日志](https://storage.googleapis.com/papyrus_images/7a7ca2b4840fdec27766c7e7d6b347f0eae5819db35be81ea9b1a4e13fc27336.png)

正常的日志

如果有错误，可以在airchains discord频道问问。

更新stationd到
===========

    sudo systemctl stop stationd 
    cd ~/tracks && git reset --hard HEAD && git pull && git checkout v0.0.5
    sudo systemctl start stationd
    

常见问题
====

a. stationd日志一直是

    New Block Found
    

没有其他日志，并且不加分。

**解决方法**

重启stationd

_b. station日志中有各种奇怪的报错。_

**解决方法**

回滚并重启stationd

    sudo systemctl stop stationd
    cd $HOME/tracks
    go run cmd/main.go rollback
    go run cmd/main.go rollback
    go run cmd/main.go rollback
    sudo systemctl restart stationd
    

如果回滚无效。考虑换一个rpc试试。还是不行的话去discord英文频道和项目方反馈。

**可以在discord中文频道找群友分享的定时重启的脚本。**

查看积分
----

接下来我们需要将airchains钱包（air开头的)钱包导入到[leap钱包](https://www.leapwallet.io/)中。

点击钱包上方的按钮

点击导入助记词

![导入助记词](https://storage.googleapis.com/papyrus_images/c038877f6e7e5ced101a290837de84cec705cc97463b264eb1b8acb08fe77b39.png)

导入助记词

接下来打开

[

Station Points Program
----------------------

Station Rewards Program

https://points.airchains.io



](https://points.airchains.io/)

连接钱包，接下来你应该能看到积分，如图

如果你的节点日志正常，却没有积分。可以在discord里面问问，也许是积分的网站没有同步到最新状态。
