If you are worried about the environmental impact (which for 1 minting is fairly small) just use the PoS options available today and rant about ETH generally using PoW instead.
The article makes specific claims to the contrary
> just use the PoS options available today
Does PoS actually work today? AFAICS it's vaporware.
Yes. PoS chains using real practical byzantine fault tolerance like Cosmos Hub, using Tendermint consensus, have been running since 2018.
Which are unsubstantiated. One minting is basically one (largish) transaction. Transactions arent quite that expensive, it costs maybe $50-100 and you definitely don't put months of electricity to earn that little as a miner. I don't have the numbers but it doesn't check out.
>Does PoS actually work today? AFAICS it's vaporware.
Yes, it's worked for a while.
The author addresses the existence of Po[X]:
""" I’m sure you’re seeing the problem here- there is not a schema that doesn’t reward those who already are already wealthy, who are already bought in, who already have excess capital or access to outsized computational power. Almost universally they grant power to the already powerful.
This is also a climate issue. """
It's been coming soon on ETH. Again, you can use PoS options today outside of ETH. Tezos is a popular one, and even the biggest ETH marketplace (opensea) is adding Tezos as an option right now.
I'm not making _any_ claim about the worthiness/sustainability of the platform, just that it is what is being used. The list of "communities" on the Flow landing page suggests that it's being considered for a couple of high-profile platforms.
> today when you sell crypto art it's PoW.
I think more specifically when you sell crypto art on a platform that uses PoW, which makes this sentence a truism.
