What is a Fon smart chain?

Could you elaborate on what a Fon smart chain is and its significance in the cryptocurrency and finance landscape? I've been hearing more about this concept lately but would like to gain a deeper understanding. Is it a blockchain-based solution? What are its key features and advantages? How does it compare to other smart chains? I'm particularly interested in how it could potentially impact transactions, smart contracts, and the overall ecosystem. Your insights would be greatly appreciated.
