Why did multi-chains appear?

In recent years, the world of cryptocurrencies has witnessed the explosive growth of multi-chain platforms. The essence of multi-chains lies in the integration of different blockchains into a single ecosystem, which allows users and developers to access the best features of each technology. The reasons for the emergence of multi-chains can be summarized in several key factors: high transaction costs and the limited capabilities of many blockchains, the need for improved scalability and security, as well as the desire to create more convenient and functional solutions for decentralized applications. Multi-chain systems provide solutions for interaction between different networks, significantly expanding the horizons of blockchain applications.
