Block size

General Overview

A block contains the transactions that are made and validated on the network. The block size describes the file size of a single block. In Bitcoin, this is defined in the network protocol and is 1MB (megabyte). Crypto transactions are very lightweight related to data storage. 1MB can approximately store 2000 transactions. Different blockchains may have different block size limits.

Pros

• A larger block size limit allows for a higher transaction rate per second.
• Standardization and regulation of block size within a blockchain

Cons

can lead to stales and temporary chain splits.
