Transactions per Second (TPS, tx/s)

Transactions per second (TPS) is a measure of a blockchain's throughput, referring to the average or expected number of transactions processed by the network per second.

The term is often referenced in discussions of enterprise use cases and comparisons of blockchain scalability. While a popular metric, TPS can be misleading if not used with proper context. For instance, TPS does not reflect anything about a transaction's size or computational costs. A transaction could range from a simple cryptoasset transfer to a complex smart contract execution. Both may be considered a single transaction but have very different impacts on a blockchain's throughput capacity.
