Definition ∞ Finite block size refers to the predetermined maximum data capacity of a single block in a blockchain. This limitation is a fundamental design parameter that dictates how many transactions can be processed and confirmed within a specific time interval. It directly influences network throughput and the competitive dynamics of transaction inclusion. This constraint is a core aspect of many distributed ledger technologies.
Context ∞ The concept of finite block size is central to ongoing debates about blockchain scalability and the appropriate balance between decentralization and transaction capacity. News frequently covers discussions around increasing block size limits or implementing off-chain scaling solutions to address network congestion. Understanding this constraint provides essential context for analyzing transaction fee volatility and network performance reports.
