A batcher is a component in blockchain networks that collects and organizes transactions before they are confirmed and added to the blockchain. Instead of processing each transaction individually, a batcher groups multiple transactions together. This can improve efficiency and reduce the overall costs of transaction processing.

When users make transactions, they are sent to the batcher, which waits until a certain number of transactions accumulate. Once a batch is full, the batcher submits it as a single package to the network for validation. This method helps to minimize data congestion, lowering fees and speeding up the process.

Batching can also enhance privacy since individual transactions are less easily identifiable within a larger group. It’s commonly used in various applications, including payment processing systems and decentralized finance platforms, where smooth and efficient transaction management is essential. Overall, batchers play a crucial role in optimizing blockchain performance and user experience.
