Definition ∞ A proprietary DLT platform is a distributed ledger technology system exclusively owned, developed, and managed by a single organization or a closed group. Unlike public blockchains, its code, access, and operational parameters are not open-source or publicly accessible. These platforms are typically customized to address specific industry requirements, offering controlled environments for data sharing and transaction processing. They prioritize specific performance and security attributes.
Context ∞ News often highlights the deployment of proprietary DLT platforms in sectors like finance, supply chain, and healthcare, where data privacy and permissioned access are paramount. Discussions frequently compare their centralized control and efficiency with the decentralized, transparent nature of public blockchains. The continued development of these platforms signifies a broader adoption of distributed ledger technology in regulated environments.
