An important cog missing in the ecosystem?

It is communication.

Despite the rapid development of blockchain technology, when it comes to communication, the industry is still like the early Internet. The industry lacks a mechanism to accomplish direct communication from services such as dApps and smart contracts to users.

times are advancing

Apps should be able to reach users directly, not through channels like Twitter and Telegram. For example, if a project owner decides to suspend token transfers for some reason, they should be able to reach users immediately with a push notification instead of a public broadcast on social media channels.

Bringing Push Notifications to DeFi

Communication on the web is based on protocols that standardize notification operations on the blockchain-based DeFi ecosystem. EPNS (Ethereum Push Notification Service) is a decentralized DeFi notification protocol that enables applications to send notifications to users on Ethereum in a platform-independent manner, that is, users can send notifications on mobile phones, tablets, networks, wallets, etc. Wait to be notified. The DeFi aspect of the protocol also enables users to earn money through these notifications.

Users can opt in or out

Users can choose the services they want to get notifications from based on their preferences and goals. If someone doesn't want to receive messages from a particular app, they just need to turn off push notifications. Unlike traditional text messaging, everything is in the user's hands. This enables users to get updates on the blockchain-based services of their choice, potentially increasing their efficiency.

Thanks to the design of the push notification protocol, apps are able to provide value to their users without bothering users who don't like them.

• As with regular push notification services, the best service method is to be selective when sending notifications. Push too much and users will opt out.

• Use Cases for Push Notifications on DeFi

• There are many use cases where an application may need to notify the end user immediately. Some examples include:

• Blockchain domain names are about to expire

Token Policy Change Proposal

It’s much better for the platform to reach users directly than to announce an event on social media, where you can never be sure whether the audience actually read the content.

Summarize

How the protocol works

EPNS abstracts the data layer to facilitate sending notifications to centralized and decentralized operators. Backed by a solid infrastructure, the protocol supports the delivery of notifications from decentralized to centralized operators, and finally to centralized platforms such as iOS, Android, Chrome, Firefox, etc. Sending notifications requires users (apps only) to pay a small fee in ETH or DAI. The specific fee is determined by the governance model.
