Random Sampling

Definition ∞ Random sampling is a method for selecting a subset of items from a larger population in a way that each item has an equal probability of being chosen. In blockchain contexts, this technique can be applied to select validators in certain proof-of-stake protocols, or to audit a subset of transactions for verification purposes. It ensures impartiality and statistical representativeness, allowing conclusions about the entire dataset from a smaller selection. This method is crucial for efficiency and fairness.
Context ∞ Random sampling plays a significant role in scaling solutions and consensus mechanisms for distributed ledgers, aiming to reduce computational overhead while maintaining security. News might discuss its application in sharding architectures, where a random subset of validators processes a specific shard of transactions. The integrity of the random selection process is paramount for preventing collusion and ensuring the robustness of these systems.
