Communication Layer for Web3.0: Here's how Ethereum Push Notification Service works

cnbctv18.com:

Push Notifications have been around for more than a decade now. However, with the launch of the Ethereum Push Notification Service (EPNS), communication within the decentralised finance (DeFi) space is set to see a huge transformation.The EPNS project was announced on January 11 and is what founder Harsh Rajat likes to call ‘Web 3 communication primitive’.

The project involves various DeFi entities and will allow decentralised protocols to send notifications and messages to users. The first version of the EPNS mainnet, launched on January 11, can now be traded on WazirX and other exchanges.The protocol aims to be the de-facto communication layer for Web 3.0.

It will bring a swath of communication features like channel creation, notification sending, on-chain governance mechanism, wallet-to-wallet chat functionality and much more. It will allow exchanges to create a dedicated channel to distribute news directly to users who opt-in for the service through their wallet addresses.Also, the protocol itself does not dictate what content can or cannot be delivered to users of service or exchange.

It is up to the exchange to decide what they want to communicate with the users.Decentralised applications (dApps) will use channels to send messages directly to the Ethereum address of users. The messages will be gasless, meaning there will be no transaction cost involved in sending the messages as the notifications are sent with the EIP-712 standard, a method for off-chain data message signing.The protocol also allows people to send notifications in an open, multichain and platform-agnostic fashion.
