Proof of Existence Invoice Demonstrator

Creating an invoice and securing it via the IOTA DLT

With the shelli.io invoice generator, we are showing a very simplified concept of how an invoice can be generated and merged with a DLT network (IOTA of course).

Privacy first

This application runs completely in your web browser and shelli gets no data. So it can be used offline and is fully GDPR compliant!

Invoice authenticator

The invoice generator can confirm the authenticity of any invoice created with it. On creation, it generates a Hash from the Invoice and saves it to the tangle, to the invoice address. So it’s directly linked to the payment data. The invoice recipient can prove the correctness of the invoice with any “Proof of Existence tool” and can be sure of the invoice’s authenticity and hackers will not be able to change the invoice address! Furthermore, the audit can be done by any entity having access to the Tangle.
