- Certify chain is a blockchain based certificate generation network where an organization can issue certificates, which can then by verified by any third party.
- The hash of the certificate details are stored onto the blockchain and the verification process is carried out using smart contracts.
- The smart contract is deployed on the Rinkeby Test Network. The contract transactions can be found here.
There is one parent smart contract which can be used to generate a child smart contract for every new organization that joins the network.
These are the pages that certify chain web application has:
Users can create an account using Auth services like Google, Facebook, LinkedIn, etc. The application uses service like Auth0 to achieve this.
This page shows after the user has logged in. This is the only page that a logged in user can access. There are two tabs on this page.
-
Certificates - The users can see all the certificates that have been issued to them on this page. This section would have paginations in case there are a lot of certificates.
-
My organizations - In order to be issued certificates, the user must be added to an organization. This tab displays all the organizations the user is a part of.
The admins can only log in using a verified account accessible through a crypto wallet like WalletConnect or MetaMask.
An account is created after the master contract generates a child smart contract for the organization in question. Once logged in, the admin is redirected to the admin dashboard with four options.
-
Manage Members - Admins can add/remove members from their organization. In order to generate certificates for a user, they should be added to the organization beforehand. In case the user is removed from the orgaization, all the certificates generated by that organization for that user is removed.
-
Generate Certificate - Admin can generate certificates for the user. This is usually done in a pool, to save cost, so it might take a few hours before the certificate is generated.
-
Revoke Certificate - Certificates can be revoked if it was generated by mistake, or the user for whom it was created turns out to be malicious.
-
Profile - The admin can change the profile information for their organization which is visible to the public.
This is a showcase page where all the organizations that have signed up with Certify Chain can be visible.
This is the page where anyone can visit to verify a particular certificate using its unique ID presented to them.
The application is a Progressive Web Application Made using NextJS, database including MongoDB, and Ant design system, with Tailwind CSS.
