While Ripple Chief Technology Officer David Schwartz says he still gets most excited about payments, he’s also got his eye on carbon credits and gaming NFTs.

“We’re really excited about carbon credits,” he said,  “There's a real problem in the carbon credit space right now of provenance and making sure that things aren't issued, like there aren't two sets of carbon credits.”

Gaming, meanwhile, is another area ripe for development, as Schwartz said non-fungible tokens can help studios more easily bring users along to their newest products.
