Definition ∞ Cubic complexity describes a computational property where the resources (time or memory) required by an algorithm increase proportionally to the cube of the input size. This scaling characteristic signifies a rapid increase in processing demands as data volumes grow. Algorithms with cubic complexity are generally inefficient for large datasets.
Context ∞ In blockchain and cryptography, algorithms with cubic complexity are generally avoided for core operations due to their high computational cost. When encountered, they present significant scaling challenges, limiting transaction throughput and network performance. This makes them unsuitable for widespread adoption in decentralized systems requiring high efficiency.
