+### 5. Revoke the certificate
+
+Reginald the Regulator has identified a problem with this hydrogen certificate. The reasons for revocation are contained within the PDF document titled `Revocation_Reason.pdf`.
+
+Inform the audience that Reginald will first upload the document explaining the grounds for revocation into the system, and then trigger the revocation of the certificate.
+
+This revocation will then be finalised by the shared `ledger` so that both the reason and revocation are visible by all.

+
+It is important to state that the system is designed like this to prevent revocation from happening without a reason first being given and indelibly linked to the certificate that it is revoking.
