Blockchain CBDE Exam - Topic 3 Question 61 Discussion

Hashing Mining uses:
C) the Dagger-Hashimoto hashing while internally the EVM uses Keccack256 which is almost similar to SHA256, but has a different padding so produces different hashes.
A) Keccack256 while internally to hash values it's easy to use the Dagger-Hashimoto to create a meaningful hash.
B) the Dagger-Hashimoto hashing while internally the EVM uses SHA256 which is an alias for Keccack256.

B is misleading, EVM doesn't use SHA256 as an alias for Keccack256.

Wait, are we sure about the EVM using Keccack256? Sounds off.

A is totally wrong, Dagger-Hashimoto is not used like that.

Definitely C! The padding difference is key.

I thought Keccack256 and SHA256 were basically the same?

I vaguely remember that the EVM uses Keccak256, but I’m not confident about how it relates to Dagger-Hashimoto.

I practiced a question similar to this, and I feel like Keccak256 is important, but I might mix it up with SHA256 sometimes.

I think Dagger-Hashimoto is definitely involved in mining, but I can't recall the exact hashing functions used.

I remember studying that Keccak256 is used in Ethereum, but I'm not sure if it's the same as SHA256.

This seems like a straightforward configuration question. I'd start by reviewing the options and thinking through the implications of each one.

I'm feeling confident about this one. The logic seems straightforward, and I can see how the num array will be transformed. I'll double-check my work, but I think I've got the right solution.
