On November 4th, Casey Rodarmor, the founder of the Ordinals protocol, announced on social media a puzzle he set in the game MineCraft. The first player to solve the puzzle received a skeleton inscription called "cactusseeds". Eventually, the puzzle was solved by player @Rhynohowl. After receiving the prize, the player put the inscription on Magic Eden and priced it at 10 BTC. Casey Rodarmor commented, "It's still too low, I know what that means."
