Computational Security

Computational security relies on the assumption that an adversary has limited computational resources, making it impossible for them to break a system within a reasonable timeframe. Most modern financial systems, including blockchain protocols, operate under this model, assuming that attackers cannot solve hard mathematical problems like factoring large integers or discrete logarithms.

It allows for the practical implementation of complex financial instruments that are secure enough for current technological capabilities. As technology evolves, computational security must be updated to maintain its effectiveness against faster hardware.

It is the pragmatic choice for scalable systems.
