Why is proof of work expensive?
Proof of work is expensive because it requires a significant amount of computational power and energy to solve complex mathematical problems, which are necessary to validate transactions and secure the network. This process is intentionally designed to be costly, making it difficult for attackers to tamper with the system.
Does Bitcoin use proof of work?
I'm curious about the technological underpinnings of Bitcoin. Specifically, I want to know if it employs a proof of work mechanism in its operations.
Is BTC still proof of work?
I heard that Bitcoin uses a certain mechanism called proof of work for its mining process. But I'm not sure if it's still the case. Can anyone confirm if BTC is still using proof of work?
Is proof of work more secure than proof of stake?
I am comparing two consensus mechanisms in blockchain technology: proof of work and proof of stake. I want to understand if proof of work provides more security than proof of stake.
Is Monero proof of work?
I'm interested in understanding the technical background of Monero. Specifically, I want to know if Monero uses a proof of work mechanism in its blockchain technology.
