You won't be able to mine Bitcoin on this tech giant's devices anymore

Want to mine some cryptocurrency on your mobile Apple device? Well, starting now, you can’t.

During the annual Worldwide Developers Conference last week, the company altered its developer guidelines to include specific rules on how its devices could and could not be used to mine cryptocurrency. In short: they cannot.

Specifically, Apple no longer permits people to mine for cryptocurrencies on iPhones and iPads unless it happens off-device (that is, in the cloud). Apps that used to commandeer part of the devices’ processing power to mine in the background are no longer allowed, either. Third-party advertisements that might use the devices’ computing power to mine cryptocurrency are also banned, according to Apple Insider. (Crypto wallets and trading platforms are still allowed).

As recently as May, Apple’s developer guidelines did not lay out any specific cryptocurrency rules, except that all apps must comply with all pertinent laws for where the user is located. Now, section 2.4.2 of the guidelines specifies that apps should minimize their strain on a device’s battery and may no longer run “unrelated background processes, such as cryptocurrency mining.” The guidelines also lay out the new specific rules for cryptocurrency mining that limit people to cloud-based mining, prohibit ICOs from unestablished firms or banks, and also keep apps from rewarding people for completing tasks like downloading apps with a cryptocurrency incentive.

Apple is, admittedly, taking a strong stand here. But it’s a decision that stands to help a lot of people. While those who deliberately use their iPhones or iPads to mine cryptocurrency (even though it’s a horrifically inefficient way to do so) might be rightfully annoyed by the new rule, most people who were mining bitcoin or another currency with their iPhones probably had no clue they were doing so.

Tons of apps and third-party advertisements run distributed mining operations in the background of the devices on which they appear. That means the people running those apps or viewing third-party ads were unknowingly using their device’s processor to generate money that they would never see. They would just notice that their battery kept dying and their phone had slowed down.

But still, many voluntarily donate part of their devices’ processing power to mine cryptocurrency and send the money to charity. These white hat versions of the distributed mining operations will also get swept up in Apple’s new rules. While there’s nothing stopping those people from using their computers (which will be way better at mining anyway) instead of their phones and tablets, the loss of charitable giving is an unfortunate consequence to Apple’s otherwise well-intentioned, sweeping reforms.
