Block Merge refers to a process where multiple blocks of transactions are combined into a single block before being added to a blockchain. This can enhance efficiency and reduce space requirements, as well as improve network performance. When miners or validators confirm transactions, they typically create blocks independently.

However, during periods of high transaction volume, it can be beneficial to merge blocks to prevent congestion. By consolidating transactions from several blocks, the overall network can process these transactions more effectively.

This process can also minimize the potential for orphaned blocks, which occur when two blocks are created simultaneously without being linked. Merging helps ensure that only one version of the block is added to the blockchain, maintaining its integrity and security.

Block Merge may improve scalability, enabling the system to handle more transactions without requiring significant increases in resources or infrastructure. Overall, this method helps maintain a smoother and more efficient transaction process within the blockchain network.
