Real estate’s illiquidity and centralization present significant inefficiencies for investors, especially those purchasing properties abroad. There are currently no international standards or comprehensive technologies for electronic property rights transfers. Legacy registry systems were created to handle local investors, but are ill-equipped to manage international ownership transfer. To solve these problems, the Propy Registry is powered by smart contracts to track and execute real-estate transactions according to regional regulations. By using the Ethereum Blockchain, Propy allows brokers, buyers, sellers, and title agents/notaries to sign off on transactions using private keys within their existing legal frameworks.
