What network is SXP on?

Could you please elaborate on the network that SXP, the cryptocurrency, is currently operating on? I'm curious to understand the underlying technology and infrastructure that supports its transactions and smart contracts. Is it a decentralized network with its own blockchain, or is it built on an existing platform like Ethereum or Binance Smart Chain? Knowing this information would help me better assess the potential and risks associated with investing in SXP. Thank you for your assistance in clarifying this matter.
