VERIABLE & INTERNET COMPUTER, THE BEST OF BOTH WORLDS!

VERIABLE and the Internet Computer are a good combination. With VERIABLE we
connect a WEB2 application with the current state of the art WEB3 blockchain
technology. The best of both worlds, in our opinion.

Although VERIABLE is not a 100% on-chain application, we use two essential
elements from the Internet Computer ecosystem:

 1. The Internet Identity and
 2. The storage capabilities of the Internet Computer in order to store the
    VERIABLE Verified Credentials (VVC) in a tamper-proof and reliable way.


INTERNET IDENTITY

Our goal was and is to prioritize data protection and IT security. Therefore, in
addition to a traditional login with user name and password, VERIABLE also
offers a login using the Internet Identity.

With the help of the Internet Identity, users and participants can log in
securely without a password using their biometric data, such as face ID or
fingerprint.

The Internet Identity is a blockchain-based authentication system for Web2 and
Web3 applications that combines public standards such as Web Authn and FIDO
(Fast Identity Online) with chain-key cryptotechnology. This allows users to
create secure sessions using their device’s fingerprint sensors or face ID
system, or using external hardware wallets.

The main advantages of using the Internet Identity are a simple and secure
application, as well as the fact that only W3C standards are used. This means
that no additional tools or software are required in addition to the browser.

Once your VERIABLE account has been linked to the Internet Identity, you can log
in using your Anchor ID and the face ID or the fingerprint of your device, for
example. The session is signed in a TPM (Trusted Platform Module) chip on your
device, where your cryptographic passkey is stored. This means that all relevant
information remains stored on your device and your password cannot be lost or
hacked.

VERIABLE VERIFIED CREDENTIALS (VVC)

VERIABLE Verified Credentials are a secure proof for all certifications that are
carried out via the VERIABLE platform. They guarantee the validity, integrity
and authenticity of a certification - created with the public standard of the
W3C consortium.

A VVC is essentially a file in JSON format. This file contains all relevant
information that provides information about the subject of the certification
itself as well as the issuer (credential metadata), the owner (claim) and all
information (proofs) that are necessary for the cryptographic verification.

To check if a VVC belongs to an owner, all you need is the corresponding
VVC.json file and the ID of the owner. The ID can vary and must be communicated
to the verifier. It works like a key - in simple words.

In addition, VERIABLE offers with the Apple Wallet a simple way of always having
the VVC with you on your cell phone and having it verified at any time against
the Internet Computer via a QR code. Alternatively, the certificate can also be
checked at any time via our platform with the VERIABLE VC ID and the VERIABLE VC
identity. This information is usually on every exported PDF certificate with a
QR code, which can also be used for verification.

Due to the secure storage of the VVC on the Internet Computer, all certificates
issued in this way are stored on the Internet Computer independently of the
issuer, regardless of whether the issuer uses the VERIABLE service in the future
or not. The VVC remains accessible and verifiable for the duration of its
validity and beyond.


WHY DID WE CHOOSE THE INTERNET COMPUTER?

With the help of the Internet Identity, we can offer a secure form of
authentication for both participants and customers. Customers can even set up a
mandatory use of the Internet Identity for their participants. This reduces the
sharing of course licenses and makes misuse of access significantly more
difficult.

Another advantage of the Internet Computer are the extremely low storage costs.
With around $5 per GB per year, the Internet Computer is one of the cheapest
blockchains in the world. With the so-called reverse gas model, all costs
incurred for the use of the blockchain are paid by the operator of the SaaS
(Software as a Service) solution. There are no costs for a user who retrieves or
verifies a certificate, nor for the issuer of the certificates. This reverse gas
model distinguishes the Internet Computer from other public blockchains. For
more see this link.

Last but not least, the Internet Computer has the lowest energy consumption per
transaction among the blockchains. This is a very important argument for a
climate-friendly IT. You can find out more here.
