WebIn a Proof of Work (PoW) problem, assume the total number of bits in a hash value is 10 and the difficulty of this PoW is 8. In addition, we assume the outputs of a hash function are uniformly distributed. a. What is the target of this PoW? b. On average, how many hash operations do we need to find a solution given this target? WebJul 27, 2014 · In the context of a hash, "bits of security" is a measure of how many possible outputs a hash function has, and thus, how hard it is to find an input with a given output. It's on a logarithmic scale, so each additional bit doubles the security. You can't compare the security of SHA-256, AES-128, and ECC-256.

SHA-2 is actually a “family” of hashes and comes in a variety of lengths, the most popular being 256-bit. The variety of SHA-2 hashes can lead to a bit of confusion, as websites and authors express them differently. If you see “SHA-2,” “SHA-256” or “SHA-256 bit,” those names are referring to the same thing. bakery ddo
