Push Protocol is a decentralized notification protocol that aims to provide a missing piece of infrastructure for web 3.0 by enabling users to receive notifications, be in control of them, and accumulate token incentives from them. Currently, there is no reliable way for dApps, services, or smart contracts to communicate with their users, and this lack of communication can lead to missed important events or user action requirements. Push Protocol aims to solve this problem by providing a notification mechanism for important updates, events, and actions in a decentralized manner.
