Summary

The text outlines a project for creating a real-time cryptocurrency price tracking dashboard using PubNub and EON SDKs alongside the CryptoCompare API to monitor the prices of Bitcoin, Ethereum, and LiteCoin. The project involves setting up a publisher to stream pricing updates and a subscriber to receive them, creating a real-time interface with EON for rendering charts. The publisher uses PubNub’s JavaScript SDK to publish data every 10 seconds to designated channels for each cryptocurrency, while the subscriber employs EON to display the data in the form of line graphs. Users must sign up for a PubNub account to obtain the necessary pub/sub keys, with a free sandbox tier available for up to 100 daily active devices. The text also emphasizes the importance of securing publish keys once deployed in production to prevent unauthorized data manipulation.
