Definition ∞ RPC overhead, or Remote Procedure Call overhead, refers to the computational and network resources consumed when a client application communicates with a blockchain node using an RPC interface. This overhead includes the time taken for network latency, data serialization and deserialization, and the processing required by the node to respond to the request. It represents the efficiency cost associated with external applications interacting with a blockchain’s data and functions.
Context ∞ News discussions about RPC overhead often appear in technical reports concerning blockchain infrastructure and decentralized application performance. High RPC overhead can lead to slower application response times and increased operational costs for services relying heavily on node interactions. Efforts to reduce RPC overhead, such as optimizing client libraries or implementing more efficient data querying mechanisms, are crucial for improving the user experience and scalability of decentralized applications. It remains a significant consideration for infrastructure providers and developers.
