, 1.Public blockchains most often use________ as a consensus mechanism.
A. PoS
B. PoB
C. PoW
D. PoET
Answer: C
Explanation:
Public blockchains most commonly use Proof of Work (PoW) as their consensus
mechanism, especially in well-established networks such as Bitcoin and, until
recently, Ethereum. PoW is a protocol that relies on network participants (miners)
solving complex mathematical problems to validate and add transactions to the
blockchain. This process ensures the integrity and security of the network, as it
requires substantial computational power and resources, making it difficult for any

single entity to control the blockchain.

often make it the go-to choice for public blockchains.
In summary, the dominance of PoW in public blockchains is due to its established
security and proven track record, although PoS and other mechanisms are
increasingly gaining popularity for their efficiency in newer blockchain projects.
