Beleg über Treibhausgas Emission und Minderung
Die digitale Belegführung erfolgt in Form eine JSON Datei, welche ein in sich valides und abgeschlossenes Dokument mit einem identitären Charakter ist. Der Beleg enthält alle im Zuge der Belegerstellung gesammelten Informationen, sowie die technischen Sicherheitsmerkmale zur Prüfung der Identität des Ausstellers und der unveränderten Darstellung der Daten. Der Besitzer der JSON Datei kann auf algorithmisch prüfbare Unterdokumente (Präsentationen) zugreifen, die durch Dritte, welche nicht den Beleg kennen, ebenfalls eine unabhängige Validierung ermöglichen.
Die JSON Dokumente dienen lediglich zur Struktur und Semantik der Darstellung eines Beleges. Der Beleg selbst - das JSON Dokument - kann als Nutzlast in ein JWT oder eine AS4 Nachricht eingebunden sein.

Beispiel Beleg: certificate.sample.json
Grundlegende Struktur
Die einzelnen Elemente des Beleges enthalten jeweils das Attribut payload und signature. Die eigentlichen Nutzdaten des Unterobjektes sind in payload vorhanden und können entweder ein String oder ein Objekt sein. Die Signatur ist eine digitale Unterschrift, welche mithilfe eines Hashings über die gesamten Nutzdaten generiert wurde.
Die Signatur wird erstellt mit der Funktion wallet.tydids.signMessage(payload) (Implementierung) und überprüft mit der Funktion wallet.tydids.verifyMessage(payload,signature) (Implementierung). Die Funktion verifyMessage hat als Rückgabe eine Identitätskennung, des Unterschreibers (JSON Pfad: owner.payload.issuer).
