Ethereum Push Notification Service (EPNS)

EPNS is a decentralized DeFi Notification protocol that enables users (wallet addresses) to receive notifications and earn from them. It enables wallet addresses to receive notifications in a platform-agnostic fashion from both decentralized and centralized carriers.

With incentives for users to subscribe to channels in order to gain weighted interest from the stake of the channel and with the added flexibility for channels to create different types of channels to reach out to their user in not just plain text notifications but also various forms of multimedia like video and images. Services get to fulfil their business goal to be able to reach their customers and provide a more fluid and dynamic experience. Services can now reach their users, rather than a user going to the service. EPNS sounds like a good deal for almost every participant involved.
