The purpose of this document is to be transparent about the changes that have been made to the App Mining program since its launch. The program is a work in progress, and we encourage everyone to participate in the evolution of App Mining by discussing and opening issues in our GitHub.

Format of the Changelog

Because App Mining operates in monthly cycles, we have broken down the changelog into monthly groups. Each month has three sections:

  • Operational Changes: Updates that have made an actual change in the program. This might be new documentation, changes to payout structure, changes to reviewers, changes to ranking calculations, etc.
  • Dry Run: These are changes that have been made, but will not have an effect in that month’s final rankings. When we make a big change, like adding a new reviewer, we usually run a “dry run” so that we can see what the results would be, without actually making them final. This allows the community to evaluate the changes before they’re finalized.
  • Discussions Finalized: These are largely discussions made from GitHub issues that have been debated, but no actual operational changes were made. These discussions all influence potential decisions in the future of the program, but will not be actualized at this time.

    • Digital Rights App Reviewer Authentication Assesment #60
      • Result: Digital rights reviewer will not provide an exact testing environment, but will test various environments changing month to month. Review will be conducted on the current public release of mac, windows, ios or android with either the default browser on the platform or the current release of chrome or firefox. If your app fails this test, by definition you're not eligible for App Mining since your app does not have working Blockstack auth. For April App Mining, the Digital Rights reviewer will test all apps, then notify all the apps that fail via email. Then 48 hours later, the failing apps will be retested. Only then will they be disqualified for the April cohort. We may reevaluate if needed.

    • Publish guide on best practices for App Mining #21
    • Hello-World Apps Not Qualifying for App Mining #34

    • App Mining Rules for Hardware Apps #35
