What network does EGLD use?

Could you please elaborate on the network utilized by EGLD? I'm quite curious about the technological backbone that supports this cryptocurrency. Could you explain the specific type of network architecture it employs, its scalability features, and perhaps even any unique advantages or innovations it might offer compared to other networks in the cryptocurrency space? I'm also interested in knowing if it's a decentralized network and if so, how does it ensure security and transaction speed? Thank you for your time and insights.
