What Is Kaspa Transaction Finality Time?

Different wallets, exchanges, and applications may recognize transactions as final at different points, based on their confirmation thresholds.

Kaspa is designed around extremely fast confirmation and settlement times. It features instant transaction visibility and typically achieves full probabilistic Time to Finality (TTF) in under 7 seconds, with some transactions finalizing in as little as 3 seconds. Most transactions are fully settled in under 5 seconds, meaning they are already spendable.

As soon as a transaction is broadcast to the Kaspa network, it becomes visible immediately. This is largely enabled by Kaspa’s 100 millisecond block time (10 blocks per second), which ensures that new blocks - and the transactions inside them - are created and propagated across the network at extremely high frequency, eliminating the long waiting periods.

Why Kaspa Is So Fast

Kaspa currently produces 10 blocks per second using the PHANTOM GHOSTDAG protocol, a rate that has been live since the Crescendo hardfork on May 5, 2025. Because blocks are created every 100 milliseconds and processed in parallel, confirmations accumulate extremely quickly, pushing transactions toward near-instant settlement.

Future Improvements to Finality

Future upgrades, including the DAG KNIGHT protocol (a parameterless generalization of Nakamoto consensus), are designed to raise block production to 32 blocks per second and eventually 100 blocks per second.

Higher block rates will further reduce confirmation times and make time to finality even faster, while preserving the same security model.
