App Mining FAQ

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.

The pilot run begins December 1st 2018, with 34 Blockstack Apps enrolled. A previous alpha run in Oct 2018 included 17 Blockstack apps. App mining is a new mining model that we expect will evolve and improve over time. We look forward to feedback from our community regarding the App Mining process and program.

How much can I earn and how are rewards distributed?

Payouts for the pilot run are $100k in total each month (the original alpha run paid out $25K. In the pilot run, the highest-ranked app receives 20% of the 100K, the next highest-ranked app receives 20% of the remaining 80%, and so on (this distribution is subject to change).

Rewards are paid in Bitcoin. The payouts are administered by Blockstack PBC and facilitated by

How is App Mining different from cryptocurrency mining?

Traditionally the term mining in cryptocurrency refers to the process of contributing compute resources to the network and earning a distributed of new tokens as a reward. On the Stacks blockchain, developers can “mine” by contributing apps to the ecosystem and making applications the community wants.

What qualifies my app to compete in App Mining?

Your app should integrate Blockstack authentication for logging into your app. Your finished app should be available to the public for use. In the future, App Mining may reward apps that have taken steps to further decentralize, such as utilizing Gaia storage or the publishing your app to the Blockstack Naming System.

Does my app have to be listed on to enter App Mining?

Yes, it does.

How do I submit my application for App Mining?

Complete the submission form on We suggest registering several days before the ranking deadline — our team needs to verify your details to ensure your app qualifies. When you have met all the requirements, you should see your app listed on this page.

How often can I submit my application for App Mining?

You need only to submit your application once. Each month after your submission, your app is competing in App Mining.

Does my code repository need to be public?

Your application code can be public or private.

Is Blockstack Auth difficult to integrate?

If you’re already building your app with JavaScript, adding Blockstack authentication is easy! We have docs, tutorials, and thorough API references for you to learn from. Vist the Zero-to-Dapp tutorial for end-to-end training. Or use this short example.

If you’re developing a traditional server-side application, you can still take advantage of Blockstack authentication. For an example, check out our Ruby on Rails gem.

Who are the app reviewers?

App reviewers are currently selected by Blockstack PBC. Reviewers are entities that have a proprietary methodology that helps them make objective judgements for why a certain app might be better than others. We strive to engage a diverse coalition of app reviewers with the goal of making application ranking objective and resilient to abuse.

At the time of our App Mining alpha (October 2018), the reviewers were: Product Hunt and Democracy Earth (who uses software to collect votes by Stacks token holders). Future reviewers could expand to community election. Please see our forum to ask questions or make suggestions for App Mining.

How are apps ranked?

App reviewers have a proprietary methodology that helps them make objective judgments for why one app might be better than another. Each app reviewers determines the data, formula, and personnel they wish to utilize. For example, Product Hunt can tap into their community data to determine relative app popularity. Reviewers are required to publish their methodology to ensure transparency periodically.

We've published a detailed explanation of our ranking algorithm on our blog and our documentation, where you can learn more.

Do I have to Hunt my app on Product Hunt?

As part of the ranking process, there is an assessment by App Reviewer Product Hunt via their community vote and their internal team vote. More info on the algorithm, here. The Hunt launch will have an impact on your final ranking, as you can see in the algorithm breakdown. Here is more info on Product Hunt launch best practices. In general, sharing and responsiveness to questions are encouraged and it might help your community reception if you choose to hunt the app yourself. If not, Product Hunt can hunt your App as well.

Apps will be hunted every 6 months, so if you hunted your app in a past month, as long as you are in the 6 month time window you will not have to Hunt the app.

Can developers engage with voters on Democracy Earth?

As of this time, they cannot. In the future, a feature that could be interesting here is allowing developers to comment only on their app and not others.

What’s the incentive for user voting?

Voters in the App Mining ecosystem are currently Stacks token holders with incentive to strategically allocate resources in the ecosystem to apps they consider highly valuable.

What are examples of any quantitative metrics that may be shared with app reviewers?

Qualitative meticrs are metrics that evaluate elements such as engagement, DAU/MAU ratios etc from the reviewed apps. Blockstack plans to incorporate metrics based ranking. However, before we do, any mechanism must thoughtfully incorporate the digital privacy rights of Blockstack users, and provide information in a way that cannot be gamed.

Is App Mining Decentralized?

Given the pioneering nature of the program, we are being careful and starting in a centralized fashion that allows for necessary diligence. We don’t want to bake in assumptions that have not been validated. The downside of this protection is some level of centralization, which we are taking steps to reduce over time. The pilot is the just the first step in creating a fair system that can be relied upon by founders and contribute to the growth of the Blockstack ecosystem.

Blockstack plans to move along a path to decentralization and App Mining will too. It is important to highlight that initially App Mining will purposely have a few points of centralization highlighted below, which can become decentralized over time (all plans are subject to change, legal approval, and applicable law).

Electing app reviewers:

Currently, Blockstack PBC elects app reviewers. In the future, we anticipate gradually transitioning to community elections of App Reviewers.

Registering apps:

Currently, registering apps is regulated by Blockstack PBC through In the future, we anticipate transitioning to publishing on designated Blockstack namespaces via our public blockchain.

Collecting votes:

Currently, votes are aggregated by Blockstack PBC and administered via In the future, we expect that votes will be collected through the protocol itself.

Issuing money:

Currently, payouts are issued by Blockstack PBC. In the future, we expect that payouts will over time be generated and deployed on an automated basis.

How is App Mining protected against bribery, collusion, or gaming?

We are taking potential threats very seriously and hope to create a fair system that continuously reinforces trust within our community for the long term.

We are currently consulting with a team of 3 Ph.D. Game Theorist professors from Princeton University and New York University to determine thoughtful methods to protect App Mining from being attacked and/or abused. Our goal is to be as transparent as possible, but App Reviewers may reserve the right to keep some secrets in their formula to avoid bribes and gaming, and the algorithm that combines all of these score may be tuned in the future to account for new learnings.

The Game Theorists are working with us to create a technical paper and broader documents like blogs explaining the overall mechanism

What is the Blockstack Ecosystem?

The Blockstack Ecosystem has a mission to bring a new internet where users control the access to, and use of, their own identity and data. With this mission in mind, three independent entities were formed:

  • Blockstack Public Benefit Corp (PBC)
  • Blockstack Signature Fund
  • Blockstack Token LLC

These three affiliated entities drive the advancement of the Blockstack mission. All three entities are committed to building a new internet where users fundamental digital rights, such as security, privacy, anti-censorship, are always respected.

What is Blockstack PBC and the Blockstack Platform?

Blockstack Public Benefit Corp. (PBC) started development of the Blockstack Platform in 2014 and launched an alpha of the platform in early 2017. The Blockstack Platform is the easiest way to start building decentralized, blockchain-based apps. It provides a complete decentralized application stack, powered by the Stacks blockchain, and maintained by a community of 7000 developers.
