Frequently Asked Questions



What's a Dapp?

A dapp is a decentralized app—an application that lets users own their data and runs without any single centralized operator.

If you use traditional apps, your digital rights, privacy, and choices are severely limited. These app ecosystems serve to enrich a small number of powerful corporations by centralizing user identities and data storage.

Decentralized apps offer a solution based on blockchain technology. Dapps link developers and users directly, without middlemen hosting software or managing user data. These customer-developer networks are more transparent, equitable, and resilient than traditional apps—with all parties incentivized to treat each other well as they rapidly innovate.

Today there are thousands of dapps built on protocols like Ethereum, Blockstack, and many others. While definitions are rapidly evolving, here are some criteria aligned with the future:

  • Do customers own their network identity? Can anyone else revoke that identity?
  • Is customer data encrypted? Can anyone else decrypt that user data?
  • Is customer data stored on decentralized networks with reconfigurable APIs?
  • Is the app open source? Can community members contribute or fork the software?
  • Is the app publishable and hostable by others or only a single company?
  • Is the app running client-side or on a server?
  • Does the app limit or clearly communicate the scope of data logging?


About app.co

App.co surfaces the best new dapps every day. It’s a place for blockchain-loving nerds, enthusiasts, and investors to geek out over the latest decentralized tech—from currency exchanges to mutant-feline-marketplaces.

App.co is sponsored by Blockstack, a decentralized app protocol and community. All protocols are welcome on App.co as we’re committed to celebrating an open, decentralized internet for all.

Blockstack is the easiest way to start building decentralized, blockchain-based dapps. Our APIs provide decentralized storage, password-less auth, and a scalable foundation for your dapps. And, Blockstack let’s you decouple the personal data you create, from the dapps you use, which makes you the sole owner of that data.



Rankings on app.co

If you've been browsing the dapps on app.co, you'll notice they are sorted by something we call 'Tweets/Week'. This measure will be evolving over time, but for now, we wanted to give you a little insight into exactly how it works.

For right now, there are two pieces we add together that make up the Tweets/Week number you see in the right-hand column (which determines rank on the page):

  • The number of tweets that contain the URL of the project
  • The number of tweets that mention the handle of the project

We run a query on Twitter for this information every day at 12am EST to collect information on the last 7 days.

Here's a quick example: A project's handle, such as @graphitedocs might have been mentioned in 100 tweets. On top of that, the URL to their site (https://www.graphitedocs.com/) was found in 900 tweets. Their number for Tweets/Week then, would be 1000.

Note: If a tweet mentions the handle of the project and has the URL, it only counts once. We'll also be introducing logic shortly to eliminate self mentions i.e. the project's handle tweeting it's own URL will not count.

Bigger picture, we'll be looking to add additional parameters to the rank or offering additional ranking options entirely. For example, the next push will likely be ranking based on traffic to the project's website (based on data from Similar Web). Another example may be sorting by upvotes or other forms of your input.

We're also working on a program where the dapp creators can give us verified data on their Monthly and Daily Active User counts so you'll be able to sort by that information eventually as well (assuming our pilot with it goes well and is sustainable and accurate).

We'll keep this post updated as ranking logic is tweaked or other sorting options are introduced. Let us know what you'd like to see or if you have any questions!
