Sublinear Space Complexity

Definition

Sublinear space complexity describes an algorithm that uses memory proportional to less than the size of its input. This computational efficiency measure indicates that the memory required by an algorithm grows slower than the input data size, often logarithmically or as a fractional power. In blockchain technology, achieving sublinear space complexity for certain operations, such as verifying the state of a large ledger, is crucial for scalability and reducing the resource demands on network participants. It permits processing vast datasets with limited memory.
