Am I eligible?
You must build and submit a new Blockstack application to be eligible. If you've never registered your app for App Mining powered by Blockstack and App.co, you're likely eligible to compete. To win, you must submit your application to the App Mining program. Please see the full eligibility requirements here.
Can I win in multiple categories?
Yes, you can win any place (1st, 2nd, 3rd) in up to two of the three categories. For example, you could win 1st prize for 'Most Fun' and 2nd in 'Best Design in a Lightning App'. You could also win the top prize in two categories, 2nd place in two categories, or any combination. If you place in more than 2 categories, your top two placements will be taken. One entry per person.
Can I compete if I'm already in App Mining?
Yes, but it must be an original application, meaning it cannot be an app that provides the same function or value to its user as the one you are entered in App Mining with. If you have a more specific question on this, please contact [email protected].
Are there any other requirements for my submission/app?
Yes, apps submitted to the Can't Be Evil Contest must qualify for App Mining, so the submission requirements for that program, as displayed below, must be met. Learn more about App Mining.

Requirements: Your app should integrate Blockstack authentication for logging into your app. Your finished app should be available to the public for use. The application must use a registered domain name and the app should be hosted at a URL belonging to the domain. The app website must use a secured (https) connection.
What is App Mining?
Traditionally the term mining in cryptocurrency refers to the process of contributing compute resources to the network and earning a reward. In the Blockstack Ecosystem, instead of just mining through computation, developers mine by building apps and the Blockstack community funds them simply for being pioneers in the emerging Blockchain software market.

We believe App Mining represents a revolution in app funding, allowing small teams to bootstrap without advertising or venture capital. Each month, qualifying apps compete for funding. Qualified apps are evaluated and ranked by expert app reviewers. The better your app, the higher payout you earn.

October's run paid applications $200,000 USD, including ~$22k to pDrive, ~$19k to Arcane Maps, and ~$15k to Dmail.
