What network is Altura on?

Could you elaborate on the network that Altura is currently operating on? I'm curious to understand the underlying technology and infrastructure that supports this cryptocurrency. Is it built on a well-known blockchain like Ethereum or is it a unique network with its own set of protocols? I'm interested in how Altura's network handles transactions, scalability, and security measures. Additionally, does Altura have plans to expand to other networks in the future, or is it committed to its current platform? Any information you can provide would be greatly appreciated.
