What is the most efficient way to find all prime numbers?

I'm curious, what's the most efficient method to uncover all prime numbers? I've heard of various algorithms like the Sieve of Eratosthenes, but are there any newer or more efficient approaches that have emerged in recent years? Given the vastness of numbers, especially as we delve deeper into the realm of cryptography and blockchain technology, efficiency in prime number generation becomes increasingly crucial. Could you elaborate on the current state-of-the-art in this field?
