If Alice can send the "same" $10 to both Charlie and Bob, the payment system ceases to be useful. The payment system needs a way to choose which transaction should succeed and which should fail, in such a way that all participants agree on which transaction has happened. Either of those two transactions is equally valid on its own. However, different participants in the payment system may have a different view of which transaction came first.

Conventionally, payment systems solve the double spend problem by having a central authority track and approve transactions.

In such a system, all participants follow the central authority's decisions.

Distributed ledger technologies, like the XRP Ledger, have no central authority. They must solve the double spend problem in some other way. Distributed ledger technologies, like the XRP Ledger, have no central authority. They must solve the double spend problem in some other way.
