As AI hype in the crypto space continues to heat up recently, the cost of registering a subnet on Bittensor, a leading AI network, has reached a record high of $6.7 million, DL News reported, Wu said. Last month, the cost to register a subnet was 100 TAO, about $53,000. The current fee to register a subnet has increased by 10,000% compared to last month. A subnet is a private network integrated with the Bittensor blockchain, with its own miners and validators that perform unique tasks, often related to AI. Every time a project registers a subnet, the registration cost doubles, and if no one registers, the price is linearly halved over four days.
