While hashing, the hashing function may lead to a collision that is two or more keys are mapped to the same value. Chain hashing avoids collision.

The MinHash algorithm is actually pretty easy to describe if you start with the implementation rather than the intuitive explanation. The key ingredient to the algorithm is that we have a hash function which takes a 32-bit integer and maps it to a different integer, with no collisions.
