What Is ‘Block Space’ and Why Is It Limited?

Block space refers to the finite amount of data storage capacity available within a single block on a blockchain. It is limited by the network's consensus rules, such as Bitcoin's block size limit (or block weight limit).

This limit is a deliberate design choice to prevent network spam, maintain decentralization by keeping the blockchain manageable, and ensure that nodes can easily verify blocks.
