This is a unique feature of Astra, a new social network that's just been launched in Vietnam. It's also the first social network in the world to reward its users. Astra uses blockchain technology and smart contracts to make payouts. Users are each given a unique wallet address and a personal key. The system will calculate the reward level corresponding to the quality of users' articles, and the payment will automatically go into the user's electronic wallet. The founding team believes that the compensation feature will help attract participants with honest and quality contributions, thereby meeting the research needs of travel lovers.
