PSP (Private Social Platform) is dedicated to creating a differentiated social platform, aiming to achieve high-levels of privacy in social interactions, catering to the needs of new-generation internet users, and filling the gaps left by platforms like WeChat and Weibo. Built on the Ethereum public blockchain system, any user with an Ethereum address can freely join the platform and engage in social activities, ensuring a vibrant initial launch. PSP integrates common social features such as messaging, group chats, and social circles. Users can choose private social modes for any social operation, which routes relevant information through the Ethereum network for encrypted transmission.
