To determine if websites, service providers, or projects of any kind can be trusted, in the Web 2.0 world we use review systems, trust badges or simply the search rank on the results page of a search engine. Often, however, these signs of trust are manipulated, paid for and fabricated by fake reviewers. Projects put fake endorsements of well-known companies or people on their website, or use company logos of trusted companies as advertisements without their consent or knowledge.
Web 3.0 offers the possibility of making statements by companies or people about one another cryptographically verifiable. Trusted entities (e.g., domain experts) can delegate their hard-earned trust to others by endorsing their work.
For example: A startup is sponsored (e.g., by Microsoft) and would like to embed the Microsoft logo on the website to establish trust with new customers. Instead of simply embedding a JPG, the permission issued to use their badge, which may be time-limited, can be checked. As soon as the permission expires, the logo/badge of certification also disappears from the website.
Or: IOHK/IOG has confidence in a Catalyst project and makes a positive statement about them: instead of a mere HTML text on a project web page, a visitor can cryptographically prove the statement and trace it back to a DID of IOHK/IOG.
A management-area for websites-owners to register their site, prove their ownership, connect their identity wallet, manage existing endorsements and send invites. Generate a JS-Snippet with configuration options to use on their website.
The certifier-Portal for organizations or people to connect their DID and issue endorsement to registered websites or DIDs. Manage existing endorsements and revoke them if necessary. Use custom images, badges, or logos to represent an endorsement instead of written text, e.g., a Catalyst Funded Project-badge.
A customized JS-Snippet gets rendered on the Holders-Websites with a cryptographic guarantee, that the statement is indeed from the specified holder. Clicking on the text/badge links to the verifier portal in which the details of the Verified Credential are shown, as well as existing metadata provided by the Issuer to reinforce the credibility of the statement made.
