> what does that have to do with your local books?

It's how double-entry bookkeeping works. Money can neither be created nor destroyed. On your local books you have an account where money goes and appears to be destroyed, but in reality there is a doubled entry in someone else's books. Just because you're unaware of it does not mean it does not exist.

And it's true that bookkeepers will have splits in their ledger in which one transaction consists of multiple entries, but that's a convenient shortcut for consolidating multiple items each of which is one half of a double entry. It has no bearing on how double-entry bookkeeping works and just needlessly complicates a description of the fundamentals. It has only to do with conventions for recording double-entry bookkeeping, just like using DB and CR to indicate whether entry is moving money into or out of an account.

The fact that you have a counterparty with his own books has nothing to with the phrase “double-entry accounting”, it is a method of keeping your own books.

> It's how double-entry bookkeeping works.

Sorry, but no. I have no idea why you think double entry means 1 of the entries is in some other persons books that you don't have access to is somehow useful. Double entry is 100% local to a singular set of books.

The point of double entry accounting is to avoid many simple mistakes. If you can't access a 3rd parties books to check, what is the point of double entry accounting, when you only hold a single entry?

I literally have no idea how you think this even remotely makes sense.

> Money can neither be created nor destroyed.

Totally as an aside, money can indeed be created and destroyed, the govt and even banks do it all the time[0]. But I agree practically speaking from an accounting perspective in a singular person/organizations books money isn't created or destroyed it's just moved around. But for double entry accounting, it's 100% not useful to talk about money in some other person's books, it's irrelevant.
