Who is eligible for Stark net?

Could you please explain who is eligible to participate in StarkNet? I'm quite interested in exploring this platform but want to ensure I meet the necessary criteria. Is it open to individuals, businesses, or both? Are there any specific requirements or qualifications that need to be met? Additionally, are there any geographical restrictions that could potentially limit my access to StarkNet? It would be helpful if you could provide a comprehensive overview of who is eligible to take advantage of this platform. Thank you in advance for your assistance.
