## Double Spend Probability

Double Spend Probability is the likelihood that an attacker can successfully spend the same digital asset twice by manipulating the ledger state. This is the primary threat that consensus mechanisms are designed to prevent.

In a secure system, this probability is kept near zero through rigorous cryptographic validation and consensus rules. If a protocol has a high double spend probability, it cannot be used for financial derivatives or any form of value transfer, as the lack of trust would lead to immediate market failure.

Financial engineers analyze this metric to assess the safety of using specific assets as collateral in lending and margin trading environments.
