Bitcoin Cash used the same codebase as Bitcoin but adjusted the block size limit. They increased the block size to 32MB. At the time of the fork, anyone holding Bitcoin was also given the same amount of Bitcoin Cash. The increase was controversial because it disenfranchised smaller miners who had slower equipment.

Many miners feared that they couldn’t be competitive mining larger blocks. There was also concern that the larger block size would lead to centralization of the Bitcoin blockchain network.

Blocks that make up the Bitcoin blockchain are limited to 1MB in size. This limits the number of transactions that the Bitcoin blockchain can handle to seven transactions per second. New blocks occur on average about every ten minutes, but they aren’t guaranteed.

These limitations are hard-coded into the Bitcoin protocol and help ensure that the network stays decentralized. And decentralization is key to Bitcoin’s robustness. Larger blocks would impose hardships on the miners and might push out small operations.
