The Raspberry Pi single-board computer, originally just a small British hacker project, has gained tremendous popularity throughout the computing community for a wide range of applications.
Among both Bitcoin-related as well as DIY or life-hacker projects, it is common to stumble upon a Raspberry-Pi-recommendation in a recipe’s ingredients list. You may actually be hard-pressed to find Bitcoin or Alt coin miners and similar specialist hardware not using a “Pi” as a controller unit these days.
Another popular use for Raspberry Pis is Bitcoin cold storage, i e running a small, offline or “cold” and ultra-secure machine for crypto coin Private Key storage. Apart from its low price, a key suitability reason here is safety. Just like “dumb printers” without Wi-Fi capability, Raspberry Pis come equipped with only some rather basic functionality not including Wi-Fi or similar security risks.
Until now, or Raspberry Pi version Raspberry Pi 2 Model B (Quad Core CPU 900 MHz), that is.
The Raspberry Pi project has just revealed its latest model, a revised Raspberry Pi single board computer with somewhat, though not fundamentally, improved performance. One of the latest version’s key “features” is rather a bug when it comes to security considerations: the Raspberry Pi 3 Model B now has built-in Wi-Fi hardware for “improved” connectivity.
This may or may not be a “nice-to-have” for many Pi users, but the fact is that this dilutes the original Raspberry Pi concept of having a *simple* single-board computer that can be equipped with extra features (such as Wi-Fi or graphic interfaces or any sort of *peripherals*) when and *if* needed. From a professional or from a systems engineering point of view it does not make any sense whatsoever to load a single-board computer core unit with specialty peripherals like Wi-Fi, or maybe a CD or HD drive for that matter — which all are a specialty for a reason: security!
It, therefore, turns out that the Raspberry Pi 3 Model B is not an upgraded but a dumbed-up (as opposed to dumbed-down) version of a previously highly attractive little machine.
The obvious solution for the security-aware — as well as health-conscious and EMF averse — user is to buy the “old” or previously common Raspberry Pi 2 Model B (Quad Core CPU 900 MHz) that does not attempt to tell you what’s good for you if it isn’t and does not have built-in security leaks or potential backdoors by design.
While there may be users or potential Raspberry Pi buyers out there who appreciate the added Wi-Fi capability of the Raspberry Pi 3 model, anyone considering a “Pi” for Bitcoin cold storage or similar applications where a hardened machine is a pre-requisite should buy the existing or “old” Raspberry Pi 2 Model B (Quad Core CPU 900 MHz) model before the “Pi” makers might come up with the idea of stopping Raspberry Pi 2 Model B (Quad Core CPU 900 MHz) production.
