Definition ∞ RPC costs refer to the expenses associated with making Remote Procedure Calls, which are requests made by a client program to execute a procedure in a different address space, often on a remote server. In blockchain contexts, these costs typically involve fees paid for interacting with a node to read data or submit transactions to the network. These expenses are part of the operational overhead for decentralized applications and services. They reflect the resource consumption of network interactions.
Context ∞ For developers and users of decentralized applications, managing RPC costs is a practical consideration for economic efficiency. News in the blockchain space sometimes discusses network congestion or increased demand leading to higher RPC costs, impacting user experience and application profitability. Protocols and infrastructure providers are continuously working on solutions to optimize these costs, such as improved scaling solutions and more efficient data retrieval methods.
