Blockchain interoperability is transforming the real estate industry by facilitating seamless cross-chain asset transfers and enhancing smart contract functionality. This advancement allows for improved property management and investment opportunities through the integration of oracle services, which enable smart contracts to respond to real-world data such as property valuations and maintenance logs. Blockchain-as-a-Service (BaaS) providers are crucial in this evolution, offering infrastructure that supports interoperability and oracle integration without requiring extensive blockchain expertise. Real-world applications include automated rent payments, instant insurance claims, and predictive maintenance driven by IoT sensors. The market for blockchain interoperability is poised for significant growth in the coming years.
