Architecture

Pingify combines smart contracts, decentralised storage, a messaging layer, client applications, and some lightweight lambda functions to provide all digital identity and interaction for physical items.

Smart contracts form the core logic and data storage on the Polygon Network for secure interactions, independent of outside failure and low gas fees.

Applications, consisting of a mobile app for end users, and web app for user interacting with NFT sharable URLs provide the full interface required to interact with Pingify NFTs.

Communication and chat functionality is delivered over Push Protocol (formerly EPNS), a fully encrypted Wallet to Wallet encrypted communication network.

Push notifications are linked using a single lambda function that utilises encrypted on-chain data to derive the users firebase id and delivery device notifications.
