What makes XLM different?

Could you please elaborate on the unique aspects of XLM that distinguish it from other cryptocurrencies? I'm particularly interested in understanding its technological innovations, as well as any potential advantages it offers in terms of scalability, transaction speed, and cost-efficiency. Additionally, how does XLM's decentralized nature contribute to its uniqueness? Is there a specific use case or market segment where XLM excels? I'm also curious about the community surrounding XLM and its potential for growth in the future. Thank you for your insights.
