It seems these days you can't mention
anything to do with cryptocurrency without someone jumping in and insisting that cryptocurrency is a disaster for the environment. There are differing opinions on all of this, but a few years ago, BitTorrent creator Bram Cohen set out to build a more "eco friendly" cryptocurrency called Chia. The basic idea was that, rather than using a proof-of-work system -- which involves using up a ridiculous amount of computing power, it would use a proof-of-space system, looking at how much hard drive space you're allocating. After many years of development, Chiacoin finally launched a few weeks ago. And, to pretty much prove the old axiom that there's no such thing as a free lunch, while it may not be directly wasting CPU cycles, it's impacted the world differently: by destroying the global hard disc supply chain, driving prices for hard disks through the roof -- leading people to point out that even if it's not wasting electricity like Bitcoin, it may be wasting hard drives. Some may challenge the question of whether or not this is wasteful (those hard drives are doing something...) but there are multiple reports of running Chia on SSDs is wearing them out in ridiculously short periods of time -- even to the point that some SSD makers are saying that using their hard drives for Chia will void the warranty. Yikes!
