Interoperability is becoming a key driver of digital asset evolution. It is not merely a technological innovation, but a necessary condition for connecting isolated blockchain ecosystems and enabling seamless value transfer. It is precisely this characteristic of interoperability that has allowed cryptocurrencies to gradually evolve from speculative trading instruments in their early stages into important participants in the global financial system. Projects like Stellar (XLM) are demonstrating the feasibility of this development direction by strengthening cross-chain communication capabilities and building a truly interconnected financial network. The core value of interoperability lies in breaking down information silos between different blockchains, enabling future financial systems to truly achieve efficient allocation of global liquidity.
