Via Molly White, a new company called Gripnr wants to monetize your D&D campaign, and it's as horrible as it sounds:
Gripnr plans to generate 10,000 random D&D player characters (PCs), assign a “rarity” to certain aspects of each (such as ancestry and class), and mint them as non-fungible tokens, or NFTs. Each NFT will include character stats and a randomly-generated portrait of the PC designed in a process overseen by Gripnr’s lead artist Justin Kamerer. Additional NFTs will be minted to represent weapons and equipment.
Next, Gripnr will build a system for recording game progress on the Polygon blockchain. Players will log into the system and will play an adventure under the supervision of a Gripnr-certified Game Master. After each game session is over, the outcome will be logged on-chain, putting data back onto each NFT via a new contract protocol that allows a single NFT to become a long record of the character’s progression. Gripnr will distribute the cryptocurrency OPAL to GMs and players as in-game capital. Any loot, weapons, or items garnered in-game will be minted as new sellable NFTs on OpenSea, a popular NFT-marketplace.
As a D&D veteran who once played a character (for 5 minutes) with Gary Gygax* as DM, I can't see how any gamer would want to do this. Molly White has spent the last two years documenting the ways scammers and grifters have used "the blockchain" and "NFTs" and other Web3 buzzwords to steal (or, as I believe, launder) billions of dollars. Gripnr seems like just one more scam, but I could be wrong: Gripnr could just be a lazy get-rich-quick scheme for its creators.
