Is double SHA-256 the best choice for Bitcoin?

The result of double sha256 (or triple sha256, or quadruple sha256, for that matter) is 256 bits in length. There has been a lot of conjecture over the years as to why the creator of bitcoin chose to use double sha256 in the protocol. One theory is that it was done to mitigate length-extension attacks.Jan 10, 2021
