Could you elaborate on whether Bitcoin truly qualifies as a proof-of-work cryptocurrency? In my understanding, proof-of-work systems involve miners competing to solve cryptographic puzzles in order to validate transactions and earn rewards. Does Bitcoin operate in a similar manner, where miners utilize computational power to solve complex mathematical problems and thereby contribute to the security and integrity of the network? Furthermore, how does this proof-of-work system affect the scalability, efficiency, and environmental impact of Bitcoin?

Could you elaborate on whether ZEC, also known as Zcash, utilizes a proof-of-work consensus mechanism? As a cryptocurrency and finance practitioner, I'm curious to understand the underlying technology driving its secure and decentralized transactions. Proof-of-work is a well-known consensus algorithm, and I'm wondering if ZEC, with its focus on privacy-enhancing features, still relies on this traditional approach or has adopted a different consensus method. Your insights would be invaluable in clarifying this aspect of ZEC's operation.
