Which chain is Nibiru on?

Excuse me, I'm curious about a specific aspect of the cryptocurrency world. Could you possibly enlighten me on which blockchain network the Nibiru project is currently operating on? I've been trying to keep up with the latest trends and developments, but this particular detail has been elusive. Your expertise in this field would be invaluable in helping me understand the technical underpinnings and potential implications of Nibiru's choice of blockchain platform. Thank you in advance for your assistance.
