WebDec 9, 2024 · What is a 2 universal hash function? Universal hash families. Family of hash functions H is 2-universal if for any x≠y, Pr[h(x)=h(y)] ≤ 1/n for random h∈H. What are good hash functions? There are four main characteristics of a good hash function: 1) The hash value is fully determined by the data being hashed. WebFinally, a hash function has to be collision-resistant which ensures that it has to be impossible for two different inputs to produce the same output. It is the deterministic feature, pre-image resistance and collision-resistance that constitute the three most important properties of hash functions in the Bitcoin mining process. date mef
