Sidenotes

This demo combines chained sessions and signatures. The demo doesn’t perform any checks, but shows what it would look like if first a user proves they live in the area where petition may be signed before signing. This way, signatures can be validated before storing, instead of after collecting all signatures.

What is Yivi?

Yivi is an identity wallet. This is an app on your phone which allows you to securely share your personal information, online.

For the user, it’s more privacy-friendly, since only specific information is shared. The receiver, on the other hand, can be sure the information is correct and true.
