Ethereum uses_____ as Proof of Work (PoW) whereas Bitcoin uses____based PoW.

APoB BoW

BSHAZ56 ETHASH

CPoW PoB

DETHASH SHA-256

Show Suggested Answer

Suggested Answer: D

Ethereum uses Ethash as its Proof of Work (PoW) algorithm, while Bitcoin uses SHA-256 for its PoW algorithm. Both are used to secure their respective networks, but they differ in terms of computational complexity and memory requirements.

Key Details:

Ethash (Ethereum): Ethash is a memory-hard hashing algorithm designed to be resistant to ASIC mining, favoring GPU miners instead. It requires substantial memory, which helps to ensure a higher degree of decentralization.

SHA-256 (Bitcoin): Bitcoin's SHA-256 is a highly secure hashing algorithm that supports ASIC mining. It is computationally intensive but less memory-demanding compared to Ethash.

Purpose in PoW: Both algorithms enable miners to validate transactions and secure the network by solving complex puzzles. Ethash's design helps Ethereum maintain a decentralized network, whereas SHA-256 allows Bitcoin to achieve high levels of security with specialized mining equipment.

Therefore, D. ETHASH SHA-256 is the correct answer, as these are the specific PoW algorithms used by Ethereum and Bitcoin, respectively.

I’m a bit confused. I thought both used PoW, but I can't remember the specifics. Is it really ETHASH and SHA-256?

I know Ethereum uses ETHASH, but I can never remember the Bitcoin one. Guess I'll just have to go with D and hope for the best. Maybe I should've paid more attention in crypto class.

I'm stuck between B and D, but I think D is the correct answer. SHAZ56 doesn't sound like a real thing, so I'm going to go with ETHASH and SHA-256.
