Definition ∞ Probabilistic algorithms are computational methods that rely on random sampling and probability to produce results. Instead of guaranteeing an exact solution, they offer a solution with a certain likelihood of correctness or a distribution of possible outcomes. These algorithms are often employed in complex systems where deterministic solutions are infeasible or inefficient.
Context ∞ Probabilistic algorithms are fundamental to many aspects of blockchain technology, including consensus mechanisms and cryptographic protocols, where randomness plays a role in security and fairness. Their application and theoretical underpinnings are subjects of continuous research and debate within the computer science and cryptography communities.
