Bitcoin (and many more) cryptocurrency prices have been sky rocketing for the lasts weeks/months, and thus their usage and mining. But have we stop thinking how this impacts the Climate Change? Before jumping into graphs, a quick recap on how cryptocurrencies work: when you buy or sell Bitcoins (for example), your transaction is being recorded into a distributed ledger. This distributed ledger is cryptographically secured against tampering, meaning that once anything is written into it, there is no way of changing nor removing it.
There has been a lot of noise around Monero and Coinhive lately, or web mining in general, and don’t quite agree with most of what I’m hearing. It all started with The Pirate Bay adding a web mining script to their site, so whenever you’d visit them, your CPU would be used to mine some Monero for them. That was made without any notice to the user, just “stealing” their power.
