Not a ton of hard numbers out there, but Hive-Engine is the main answer—it lets users create custom tokens directly on Hive without building their own blockchain.

A few have launched full separate blockchains (like Splinterlands/Hive-Engine ecosystem projects), but most Hive creators stick with HE tokens since it's way easier than rolling your own chain.
