Block Confirmation Depth

Block confirmation depth refers to the number of blocks added to a blockchain after a specific transaction has been included in the ledger. Each subsequent block serves as a layer of protection, making it exponentially more difficult for an attacker to revert the original transaction.

For exchanges and derivatives platforms, setting an appropriate confirmation depth is a critical risk management decision. If the depth is too low, the platform is vulnerable to reorganization attacks; if it is too high, the user experience suffers due to long wait times.

This metric is a direct translation of probabilistic finality into actionable policy. Traders often monitor this depth to understand when their assets are truly liquid and available for further deployment in margin-heavy trading strategies.
