Data Space Protocol

Definition ∞ A data space protocol defines the rules and standards for exchanging data within a shared digital environment. This refers to a set of agreed-upon technical specifications and governance structures that enable secure, standardized, and controlled data sharing among participants in a data space. These protocols facilitate interoperability and foster collaborative data utilization across various entities. They are fundamental for building trust and ensuring compliance in distributed data environments.
Context ∞ Data space protocols are gaining prominence in discussions about data sovereignty and the creation of decentralized data marketplaces. Efforts like the European Gaia-X initiative aim to establish common frameworks for data exchange. The evolution of these protocols is crucial for realizing the full potential of secure and efficient data economies, including those powered by blockchain technology.
