  Supply chains lend themselves to blockchain technology, but certain
challenges remain, especially around invoice financing. For example, the
further a supplier is removed from the final consumer product, the more
difficult it is to get their invoices financed. Moreover, for competitive
reasons, retailers and manufacturers do not want to disclose their supply
chains. However, upstream suppliers need to prove that they are part of a
`stable' supply chain to get their invoices financed, which presents the
upstream suppliers with huge, and often unsurmountable, obstacles to get the
necessary finance to fulfil the next order, or to expand their business. Using
a fictitious supply chain use case, which is based on a real world use case, we
demonstrate how these challenges have the potential to be solved by combining
more advanced and specialised blockchain technologies with other technologies
such as Artificial Intelligence. We describe how atomic crosschain
functionality can be utilised across private blockchains to retrieve the
information required for an invoice financier to make informed decisions under
uncertainty, and consider the effect this decision has on the overall stability
of the supply chain.
