NFTs are becoming bigger each day, but not without using a vast amount of energy to be created. Co2ign is a new platform that allows artists and buyers to digitally sign the NFT to cut out the carbon emissions used during the traditional Blockchain process. Carly Rector, CEO and chief architect of Co2ign Art, joined Cheddar News to discuss how the technology behind the company is a climate-friendly marketplace for digital art. “Blockchain also uses digital signatures, but it also distributes sort of the transaction ledger across many servers that are storing the Blockchain,” she said.
