And as long as honest miners have more computing power. Because they are decentralized and without a proof mechanism, the network and the data stored within it would be vulnerable to attack or theft. What is proof of stake? We need some way to prevent repeat spending of hashcash tokens. Why is proof of work necessary? What if we eliminated the proof of work step for the miners and what are the consequences of doing so? I've heard it is useful to adjust the mining difficulty (but we could do it in another manner) and this is a.
And as long as honest miners have more computing power. It was a proof of work mechanism to help deter spam email. Bitcoin uses the hashcash proof of work with a minor adaption. Proof of work, as its name implies, requires one application of this idea is using hashcash as a method to preventing email spam, requiring a proof of work on the email's contents (including.
