Definition ∞ Block batching is a technique where multiple transactions are collected and processed together as a single unit before being added to a blockchain. This method aggregates numerous individual operations into one larger transaction. By doing so, it reduces the computational overhead and storage requirements associated with processing each transaction separately. This approach significantly improves network throughput and lowers transaction costs.
Context ∞ Block batching is a key scaling solution for many blockchain networks, particularly those experiencing high transaction volumes. It directly addresses limitations in network capacity and transaction finality. The continuing evolution of layer-2 solutions and rollups heavily relies on efficient batching strategies to achieve greater scalability and cost-effectiveness.
