Mask Network is a protocol that allows users to send encrypted messages, cryptocurrencies, and even DApps interactions over social networks without leaving those platforms. It aims to bridge the gap between the decentralised Web3 and the traditional Web2 social networks by enabling a layer of privacy and utility directly on platforms like Twitter and Facebook. The MASK token is used within the ecosystem for governance, rewards, and payments, supporting a new layer of utility on top of existing social media infrastructure.
