# Build a Permafeed Hub
## PRIZE BOUNTY
1600 DAI.
## OVERVIEW
Modern web applications, both centralized and decentralized, often depend on third-party data feeds in order to function. Whether it is asset prices, weather information, or the latest headlines, our applications need data feeds they can rely on.
The data feeds that we use are points of trust in our applications. If the owner of these streams maliciously or inadvertently publishes incorrect data or their stream goes offline, our apps can break or even potentially commit major financial errors.
**Permafeeds are data streams you can trust: Transparent, decentralized, and open.**
Permafeeds are a solution to this problem. These data streams, stored on the Arweave's permanent ledger, are decentralized (ensuring uptime), and fully auditable: allowing you to track every piece of data the stream has ever provided over time, validating its quality and reliability. These are data feeds for the age of trustless computing.
## COMPETITION DETAILS
This competition is to build the best permaweb app that indexes permafeeds on Arweave. The permafeed hub should allow developers to browse feeds, reading the details provided about them by their owners as well as details extracted from the blockweave.
The winner will be the entrant that provides the highest quality user and developer experience.
## FEATURES
* Feed providers should be able to submit a wallet address where the feed can be found, a description of the feed and example GraphQL/ArQL code to access the feed.
* Users should be able to tip the feed operators in AR.
* Users should be able to browse these feeds and rank them via tips (25% of the tip must be sent as reward to the miners, in order to dissuade Sybil attacks).
* On the page for each feed, users should be able to see statistics about the feed (number of data items, last post time, first post time, etc).
* (Optional) Users should be able to run the ArQL/GraphQL test query and see the results in the browser, in order to see what the data looks like and how to use it in their apps.
* (Optional) Users should be able to leave comments on permafeed description pages so that they can share their due diligence around the data.
## RESOURCES
