# sui\_getProtocolConfig{deprecated} - Sui

This method returns the protocol configuration table for a given version number on the SUI network. Protocol configurations define network parameters, limits, and feature flags that govern blockchain behavior. This is useful for understanding network capabilities and constraints.
