Batch verification is a process used to confirm the validity of multiple transactions at once, rather than verifying each transaction individually. This method improves efficiency and reduces the amount of computational resources required.

In traditional transaction verification, each transaction must be confirmed by nodes across the network, which can be time-consuming and resource-intensive. Instead, batch verification allows nodes to check a group of transactions as a single unit. This approach speeds up the process while maintaining security and integrity.

By grouping transactions, the system can achieve better scalability. This means that more transactions can be processed in a shorter period. It also helps in minimizing the load on the network, as fewer individual verifications are needed.

Batch verification is especially beneficial during periods of high transaction volume, as it helps to ensure that the network remains responsive and stable. Overall, this technique enhances the performance of blockchain systems by streamlining the verification process while still safeguarding against fraud and errors.
