Proprietary Blockchain

Definition ∞ A proprietary blockchain is a distributed ledger technology developed and controlled by a single entity or a restricted consortium, rather than being open to the public. Access, validation, and participation in such a network are permissioned and centrally managed. These systems are often tailored for specific business needs, prioritizing privacy and performance within a defined ecosystem. They contrast with public, permissionless blockchains.
Context ∞ News frequently reports on large corporations and financial institutions adopting proprietary blockchains for internal operations or B2B solutions. Discussions often weigh the benefits of enhanced privacy and control against the reduced decentralization compared to public networks. The ongoing trend indicates a strategic deployment of blockchain technology in environments requiring specific access controls and performance guarantees.
