This is called clearing.  Many argue it's one of the killer features of
money.  Note that you can model clearing in a certain way, when parties
trust each other.

Alice owes Bob 10 euros.

Bob wishes to pay Carol 5 euros.

With permission from both parties he can reduce his debt from Alice by 5
and Alice can pay Carol 5.  So this transfer can be modeled in terms of 2
new IOUs.

In practice it's advantageous to leverage the legal framework in a country
to set up contracts and a degree of enforcement when trust is not 100%

On the web anything of significance should be a URI.  So for example you
can have


Historically finance has used the 3 letter ISO such as EUR and payswarm
supports that

But you can model just about anything with a URI including sophisticated
financial products such as baskets, futures, options, currency mints.  It's
basically infinitely extensible.
