Technical Question about LN...(not enough room to ask in this post header)

So lets say we have channels between (A,B) (B,C) (C,D).

A <------> B <------> C <------> D

And lets say B wants to send their "beads" to D.

How does D know those beads weren't spent already spent with A ??

The introduction of the LN whitepaper talks about how bitcoin is a "gossip" network - that everyone must know about every other transaction. And this is true.

So if D does not have the full history of all transactions, then how does it trust that B didn't spend with A already ??

And lets add the caveat that A,B, and C all want to defraud D.

Thinking of creating my own crypto exchange in my community

Many folks where I'm from love the idea of bitcoin but seem reluctant when it's time to get the coins. And most of them cant navigate their way around the Binance app because it's not user friendly. I was wondering if it were ok to buy bitcoins in bulk and sell it to the locals. Just like a mini crypto exchange.
