Today’s video market, live or recorded, is distributed in multiple forms across various desktop and mobile platforms. 4 | Cross platform virality and rampant copyright infringement impose on the ability for content creators to retain control and benefit from their intellectual property. 5 | 6 | The blockchain and smart contracts are new means to organize this chaotic market. Vevue DAPP is a decentralized copyright tracking and video exchange based on Blockchain. Users exchange incentive based Vevue Requests thru the mobile app to earn Vevue Token. 7 | Pin any amount of Vevue Token to any location and attach a short message. Receive video content in return. 8 | 9 | Users can also use Vevue Token as utility token for decentralized video copyright exchange. 10 | Copyright information is stored on the Qtum blockchain. 11 | Content creators can retain or transfer their copyright using Vevue Copyright Wallet. 12 | 13 | >Official Website in English https://vevue.com 14 | 15 | # 关于 16 | 17 | Vevue是一款视频分享类社交APP。 18 | 19 | 和当前大多数视频APP以人为主的定位不同，我们是基于需求的一款应用。 20 | 21 | 使用者可以通过Vevue在任何位置发起视频拍摄悬赏，可以是国内的某个景点，可以是国外某个向往已久的海滩 22 | 也可以是极地极光、海上日出日落或者是一段街头艺术，用你喜欢的方式去定义拍摄类型，或者航拍，或者延时摄影，只要你喜欢。 23 | 你的这些请求会被Vevue统统打包好发送到Vevue地图上并推送给符合条件的拍摄爱好者，完成任务即可领取奖赏。 24 | 一切都是那么简单，视觉旅游如果只有眼睛参与那太遗憾了，全身心的参与才叫体验。 25 | 26 | Vevue采用区块链技术完整记录所有原创内容的版权以及版权流向，这一切繁重的后台工作，都由我们来完成，你们尽情享受科技带来的改变。 27 | 28 |
