How Do Different Cryptocurrencies Set Their Default Confirmation Thresholds?

The default confirmation threshold is typically determined by the core developers and community consensus, often based on the average block time and the perceived security risk. For example, Bitcoin's 6 confirmations are often considered standard due to its 10-minute block time, resulting in about one hour of wait time.

Faster block times may require more confirmations to achieve a similar level of security against reversal.
