How Does a Higher Block Issuance Rate Affect the Time Required to Achieve a Safe Confirmation Depth?

A higher block issuance rate (shorter block time) means that a safe confirmation depth can be achieved in less wall-clock time. For example, a coin with a 1-minute block time will achieve 6 confirmations in 6 minutes, whereas Bitcoin's 10-minute block time requires 60 minutes.

While the total number of blocks (depth) required for security remains a function of the probabilistic attack cost, the time to reach that security level is significantly reduced, improving the user experience for faster transaction finality.
