Shared Memory

Definition ∞ Shared memory, in a computing context, refers to a region of memory that can be concurrently accessed by multiple independent programs or processes. In distributed systems, including some blockchain architectures, it can describe mechanisms allowing different components or nodes to access a common data store efficiently. This approach can enhance performance by reducing the need for data duplication or complex inter-process communication.
Context ∞ Discussions around blockchain scaling solutions or specialized layer-2 protocols sometimes involve concepts akin to shared memory, particularly in how data is accessed and processed by different execution environments. News reports might analyze how such data-sharing paradigms affect security, consistency, and potential points of contention within a decentralized network. Future developments aim to optimize data access patterns in distributed ledgers while maintaining data integrity and preventing race conditions.
