Yeah, but one is extra bad for our enviroment while being a scam.
That's what i thought, too. I would never believed if someone telled me some years ago that there will be another scam (ai) that wastes even more power.
Just wait until somebody proposes an AI powered blockchain…
The ultimate techbro venn diagram.
💀. Thats darker than anything else.
Stop giving them ideas
I seriously thought your punchline was going to be the pacific garbage patch from all that extra consumption we've encouraged.
totally agree re bitcoin, and also am very sceptical of crypto as a mass-adopted currency in general
however there are plenty of networks that don’t use proof of work to validate their chains, and they aren’t bad for the environment to nearly the same degree
They are still very unstable and rely on some sort of consensus. It is flat out a bad design. It would be safer to pay with stocks.
consensus is basically what all modern databases rely on… it’s not unstable; it has properties that need to be well known and accounted for
The problem is using that for something world wide with no backing by anything material.
It is unstable by nature
i tend to agree for mass-adopted currency, but mass currency is only 1 use case for blockchain
things like bank to bank transfers (think a replacement to swift: with semi trusted entities like a big group of banks, the proof functions can be both extremely efficient and fast whilst remaining scalable and distributed so nobody has control… of course this would be a private network, but every bank involved can audit and sign off on transactions)
blockchain at its core is an immutable log between untrusted parties… it can be used to prove a particular thing happened at a particular point, in situations where people don’t even trust governments etc to maintain accurate records
it’s too big and cumbersome to be used by everyone in the world for payment, but it’s a good facilitator of some niche things that most people won’t have any idea about
the technology is solid; it’s just very limited, and the most “profitable” and marketable uses are also the most ill-suited
I am NOT a crypto fan, but not all cryptocurrencies are bad for the environment. Ethereum is proof of stake.
