Interesting. If so, one can only hope they have a viable plan for managing CO2 emissions as a result of NFT sales and the resultant ETH transactions. Perhaps a move to a POS-based operation will help.

Example worth reflecting upon here. I also released kilos of CO2 into the atmosphere for validating test transactions on Open Sea, just to get an account set up. No value created; no one buying any art; but real damage done to the environment. Of course, the headlines of Beeple's pieces selling for millions hide however many wannabe "artists" are pushing digital art and content out there, along with CO2 for absolutely 0 real value created.
