I don’t think anything written in the post is not universal.
The chance of somebody coming up with the exact same wording just randomly is about 1 billion to 1. It is more likely that somebody would use your same choice of words,
"Every block is mined at 10mins interval by a pool.Therr is a ledger book."
Forget the fact that both of those things are wrong; its just a more likely expression by an average forum shitposter than an eloquent definition.
OP deserves a second chance.
