Ok so can someone explain to me how cryptocurrency pollutes? Like what crazy calculations are they running that they need enough brainpower to significantly effect things? Like I’m assuming what’s causing the pollution is increased electricity consumption but… how does sending lil pretend money tokens back and forth or whatever cause so much pollution?
Also, what the fuck is “mining”? How d'you mine… like bitcoin is not a naturally occurring resource, and I assume that you can’t just make it, cause that would make it instantly worthless… help?
So you get “coins” as a reward for performing the cryptographic calculations necessary to update the public ledger which is the blockchain. This is, by design, an increasingly complex and resource intensive process to slow down the collection of (intentionally finite) coins.
So every transaction with bitcoins requires the ledger to be updated with the current ownership of every already existing bitcoin, which also requires encrypting and decrypting a bunch of information and sharing it across the public ledger. So every transaction made with bitcoins increases the energy requirements of updating the ledger making it harder and harder to complete the latest version and get the coin which is a reward for doing that work.
There’s a lot I don’t fully understand myself but the long and short of it is that the actual value of any crypto currency is pretty much just what people agree on, except instead of a fiat currency where a government says it’s worth something and a mint that makes physical currency, there’s a bunch of nerds who agree that solving certain math problems is worth rewarding.
Feeling like adding on for a bit of context, I know it’s kind of hard to understand how mining for really any kind of crypto is hard to imagine, but seeing what a bitcoin mining facility looks like for the first time really helped me realize just how energy intensive it is.
See all these warehouses? They’re quite literally filled to the brim with specialized computers that do nothing but mine, each one filled with thousands of these computers, just row after row of this:
So all the power consumption winds up adding up like crazy.
Yep, that’s why cryptocurrency and NFTs are considered major contributors to pollution – because the energy needs of all those computers doing the calculation are equivalent to a medium sized country. Currently, crypto consumes more energy than Argentina.
Guess what’s inside a lot of mining rigs? Gowan, guess.
Graphics cards!
Lots and lots of these puppies side by side, spinning their little fans as fast as they can go because as it turns out: GPUs are perfect for doing the calculations required for mining cryptocurrency.
Which means amateur miners buy a lot of these things.
So many, in fact, that there is now (May 2021) a world-wide shortage of NVIDIA and AMD graphics cards and building a new gaming rig is damn near impossible because of the shortage.
OR you can pay a ridiculously inflated price by GPU scalpers on eBay.
Seriously. Places that sell GPUs impose quantity limits because if they don’t… some crypto asshole will buy out their entire stock in one go.
But the “good” news is that the professional miners (like the Bitmain site up there, in the photos) use dedicated ASIC mining rigs which don’t use consumer GPUs. But (bad news) they DO use the same sort of chips that NVIDIA & AMD rely on to make their products, which just starves the supply pipeline at a different point.
Bottom line: not only does cryptocurrency mining consume terawatts of electricity, it also consumes megatons of computer hardware. Which is expensive to produce (in resource terms, like rare metals, petroleum, water, electricity, paper) and will, someday, require even MORE resources to recycle. Or else it ends up in a landfill.
Note that current dedicated mining rigs are so highly specialized they are useless for anything other than mining. They cannot be easily repurposed to (say) sequence DNA or fold proteins for miracle cures.
What a waste.
was anyone gonna tell me that some nerds peepee poopoo “currency” is the reason why graphics cards are sold out everywhere or was i supposed to find that out from comments under a screenshot from twitter user whoreganic cop puncher explaining how bitcoin is just an artificially complicated math problem
Also I’ve read be very wary about buying used graphic cards cause there’s a chance it’s one that’s mostly heavily used from one of these bastards. These thing are very heavily used so a used one sold by one of these guys would be on its last leg of life from being on 24/7
Make sure there’s a return policy just be very careful if you’re buying used.
I knew NFT were stupid and just a dumb way to gamble but holy shit the amount of energy they use to simply create and track these things is disgusting
DON'T buy cryptoart
Leave a disclaimer on your art that states that "This is NOT for NFT sale"
So you know how uhhhh in magical girl animes the protagonist always has a cute non-human sidekick that follows them around and shows them how to use their powers?? well,,
Simon is so pretty, he literally drag me from my art block! my hero . ❤,
@businesstiger your DTIYS was so fun to do ❤,
