Decentralized record keeping is possible once privacy, security, and permissions are settled.
Blockchain uses cryptographic codes (hashes) to prevent undue manipulation of a sequence of text records.

The new enrollment experience is more convenient …
… with a global, open blockchain registry.

Mary will ultimately own her proof-of-status and store it in her own digital wallet …
… which opens up even more service possibilities …

So what is the difference?
And what is different about the role of government?

And in what sense is the credential “owned” by each person?
![Page 25: Verifiable Organizations Network - VON - Primer Slides (3).pdf](https://reader030.vdocuments.mx/reader030/viewer/2022012502/617bd07d04cec75994745833/html5/thumbnails/25.jpg)
In the centralized model, the credential is stored in a record in a database on a server.
![Page 26: Verifiable Organizations Network - VON - Primer Slides (3).pdf](https://reader030.vdocuments.mx/reader030/viewer/2022012502/617bd07d04cec75994745833/html5/thumbnails/26.jpg)
Well-managed databases are backed up routinely …
but still pose a single point of failure that is vulnerable to corruption or security threat.

Database coordination is a logistical headache …

ACCESS
Centralized databases also create gatekeepers who act as bottlenecks in the system.

HOLDERHOLDER VERIFIERVERIFIER
When a credential is shown to a verifier with a proof of ID, verification is highly fallible.
![Page 30: Verifiable Organizations Network - VON - Primer Slides (3).pdf](https://reader030.vdocuments.mx/reader030/viewer/2022012502/617bd07d04cec75994745833/html5/thumbnails/30.jpg)
Fancy print gimmicks might make a credential seem authentic but these are easy to forge these days.
![Page 31: Verifiable Organizations Network - VON - Primer Slides (3).pdf](https://reader030.vdocuments.mx/reader030/viewer/2022012502/617bd07d04cec75994745833/html5/thumbnails/31.jpg)

A decentralized verifiable credential is carried by the holder on a smart phone or other computing device.
The phone does a lot of the work as the holder’s agent.

The credential is a package of data that is now on the phone.
The credential is given directly to the holder by the issuer. No data was put on the blockchain.
