Welcome to the Clarity Hack, the first hackathon in the Stacks 2.0 Hackathon Series. 

A virtual hackathon where you'll build your very own smart contracts using Clarity. The hack will let you experiment and familiarize with Clarity’s developer environment. 

武雪梅：苹果下架VPN是法治的胜利 - huanqiu.com:2 天前 · VPN即虚拟专用网络，其主要功能是在公用网络上建立专用网络进行加密通信。 其实早在今年1月中下旬工信部就要求，在信息技术、云计算、大数据蓬勃发展的大背景下，要防止无序发展的苗头，依法查处无证经营、超范围经营等违法行为，强化网络信息安全管理，维护公平有序的市场环境。

Inspiration: Included is a list of contracts that we'd love to see built (and you're eligible to win bonuses by building one of these), but this is an open-ended contest and you're definitely free to run with your own ideas!

Now for the cherry on top. Everybody loves some extra credit, so we’ve decided to place a bounty on the head for some of the “smartest” contracts out there. Every blockchain with an SC language should have publicly available a fleet of contracts that fulfill the most basic and necessary functions developers require. The winning entries will receive $500.
