Following Apple's widely publicized mid-March removal of the Mac app Calendar 2 for running a cryptocurrency mining tool in the background, the App Store's Review Guidelines have been updated to explicitly ban on-device mining - across any type of app, and all of Apple's platforms. On macOS, however, users will continue to be able to acquire apps outside of the Mac App Store, enabling mining and other activities to continue without Apple's seal of approval.
"Apps, including any third-party advertisements displayed within them, may not run unrelated background processes, such as cryptocurrency mining", the updated policy reads.
Well, a key part of the new guidelines discusses cryptocurrencies and how cryptocurrencies and blockchain technologies can be integrated into new app development for the Apple App Store. Other cryptocurrency-related functions, like managing or trading cryptocoin funds, are still permitted.
Addressing the rising frauds with the unregulated initial coin offering-based (ICO) fundraising technique, Apple is now only allowing apps from established banks, securities firms, futures commission merchants ("FCM"), or other approved financial institutions.
Speaking to CCN at the time, Jaxx CEO Anthony Di Iorio revealed Apple had stuck to approving a select six cryptocurrencies, namely: Bitcoin, Ethereum, Dogecoin, Litecoin, Ripple and the then DAO token.
In July 2017, Apple 'approved' Dash as a cryptocurrency. Wallet apps for crypto are fine, as long as the developer is enrolled as an organization. Exchanges are fine, too, as long as they are the ones offering transactions or transmissions of currency. The guidelines noted: "Cryptocurrency apps may not offer currency for completing tasks, such as downloading other apps, encouraging other users to download, posting to social networks, etc".
