What network is eCash on?

Excuse me, could you elaborate on the network infrastructure that eCash operates on? I'm curious to understand the underlying technology that powers this cryptocurrency. Is it built on a blockchain similar to Bitcoin or Ethereum, or does it utilize a different consensus mechanism? Furthermore, what are the key advantages and disadvantages of the chosen network in terms of scalability, transaction speed, and security? I'm interested in knowing how this affects the overall user experience and potential for growth within the eCash ecosystem.
