By the time they reach many nodes, they will end up entering a block before long. This stable addition of a constant amount of new coins is analogous to gold miners who spend resources to put it into circulation. Any necessary rules or incentives can be enforced with this consensus mechanism. We will then demonstrate that the probability that a slower attacker can reach the longest chain decreases exponentially as more subsequent blocks are incorporated. The timestamp proves that the data obviously must have existed at the time to be included in the hash. The traditional banking model achieves its level of privacy by limiting access to information to the parties involved and to the trusted third party. 1980 Symposium on Security and Privacy, IEEE Computer Society, pages 122-133, April 1980.

You don't need to know the exact amount of progress the attacker has made, but assuming honest blocks took the expected average per block, the attacker's potential progress will be a Poisson distribution with an expected value of: To get the probability that the attacker can still reach us now, we multiply the Poisson density by the amount of progress he could have made times the probability that he could reach that point: We re-organize to avoid the sum of the infinite tail of the distribution ... We run some results, we can see that the probability falls exponentially with z. I think I'm even going to do a "man-on-the-street" episode for The Daily Decrypt next week, asking locals if they've heard of crypto and their experience with banks. Me gusta el "cuento corto/cuento largo" sobre todo. The steps that the network executes are the following: The longest chain is always considered the correct one and they start working on extending it.
