Stride是Cosmos 生态的多链流动质押协议，其近期宣布完成了由投资者North Island VC、Distributed Global 和Pantera Capital 共同牵头的670 万美元种子轮融资。
目前Stride有一个激励性测试网正在进行。该激励性测试网包含面向开发者，验证人和用户的任务。以下为任务列表。
其中任务9为relay interchain queries using the new v2 go relayer
使用go relayer v2中继链间查询
前提条件：服务器上已经安装好stride和gaia节点，并同步到最新区块，已经运行go relayer v2。（可参考 任务8教程）
下载并编译二进制文件
cd
git clone https://github.com/Stride-Labs/interchain-queries.git
cd interchain-queries
go build
sudo mv interchain-queries /usr/local/bin/icq
设置变量（根据你自己的情况）
STRIDE_RPC_ADDR='127.0.0.1:26657' # 填你的Stride RPC
STRIDE_GRPC_ADDR='127.0.0.1:9090' # 填你的Stride GRPC
GAIA_RPC_ADDR='127.0.0.1:23657' # 填你的Gaia RPC
GAIA_GRPC_ADDR='127.0.0.1:23090' # 填你的Gaia GRPC
设置配置文件
cd && mkdir .icq
sudo tee $HOME/.icq/config.yaml > /dev/null <<EOF

导入钱包
注意: 请务必使用与relayer任务相同的钱包。只有这种方法才能证明是你本人在中继链间查询。
icq keys restore --chain stride-testnet wallet
icq keys restore --chain gaia-testnet wallet
建立系统服务
sudo tee /etc/systemd/system/icqd.service > /dev/null <<EOF
[Unit]
Description=Interchain Query Service
After=network-online.target
[Service]
User=$USER
ExecStart=$(which icq) run --debug
Restart=on-failure
RestartSec=3
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF
开启服务，运行链间中继
sudo systemctl daemon-reload
sudo systemctl enable icqd
sudo systemctl restart icqd
查看icq日志
journalctl -u icqd -f -o cat
等待5到15分钟后（也可能几小时），你将看到如下日志。这说明你中继链间查询成功了。
Requerying lightblock
ICQ RELAYER | query.Height= 0
ICQ RELAYER | res.Height= 73007
Send batch of 4 messages
1 ClientUpdate message

之后，你可以在区块浏览器查询你的地址。在Transactions处找到SubmitQueryResponse的交易。例如
记录该交易的浏览器链接，例如我的：https://stride.explorers.guru/transaction/D14C3C397E82FF75B74D4C9CFDF1A34224E6BF9D04B0C459729B410329F4F0AB
接下来，github fork https://github.com/Stride-Labs/interchain-queries
在你fork的库中新建config.yaml。内容复制$HOME/.icq/config.yaml的内容。
例如。

之后，填写任务提交表
Include your evidence of completing the task. See the task table for instructions on what evidence to submit. 处填写你刚刚记录的交易的浏览器链接和你刚刚fork的你的github仓库链接。
