关于我们
欢迎来到贱客，这是一个内涵图交流平台，平台所有数据全部储存于链社区的智能合约当中，数据永远保存在区块链上，永不丢失。
本项目是基于星云链开发的DAPP,使用项目之前请安装星去链钱包WebExtensionWallet,不然投搞、评论、打赏功能无法正常使用，只能查看段子！
您可以投稿，发布搞笑、有趣的内涵图，但请不要发布暴力/涉黄/血腥的图片，请自学遵守相关法律法规！
投稿成功之后，用户浏览到您的稿子觉得有趣，会评论、打赏nas，打赏的nas会自动转你的钱包，没有任何中介环节.
您可以在个人中心页面中查看自己的投稿记录、评论记录、赏金记录.
如果您也想开发DAPP，在开发过程中碰到任何问题请联系我.
