Airchains 是一个模块化的 zk-Rollup 框架平台，其独特设计旨在帮助开发人员构建具有无与伦比的速度和隐私性的综合应用程序,在选择执行和数据可用性层方面提供了灵活性。 官方推特：官方网站：Making Confidentiality Accessible | Enabling zkFHEMaking Confidentiality Accessible | Enabling zkFHEhttps://www.airchains.ioAirchains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。 本教程仅供参考，请以官方文档为准 https://docs.airchains.io/rollups/cosmwasm-zk-rollup/create-an-cosmwasm-rollupCosmwasm 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stationEVM + Eigenda教程可以参考TESTCN老哥的https://medium.com/@TestnetCn/airchains-rollapp部署-3842a6cba873配置要求系统: Ubuntu 22.04安装依赖sudo apt-get update && apt-get install jq build-essential -y 安装gocurl https://dl.google.com/go/go1.22.1.linux-amd64.tar.gz | sudo tar -C/usr/local -zxvf - ;
