The processes for verifying educational credentials between recruiting companies and educational institutions are irregular, opaque, and inefficient. The vacancies created by growing economies increase the demand for low cost and efficient verification services.
Verification services are valuable for pre-employment background checks. They ascertain whether or not a candidate’s educational credentials are genuine. Verification reports are essential for making hiring decisions, and testing the honesty and integrity of candidates. Since businesses invest significantly in hiring competent individuals, effective verification plays a critical role.
Employees who misrepresent their education and experience is a common problem organizations across the globe have to deal with. The presence of a significant number of fake and unapproved institutions further compounds the problem. The need of the hour is to enhance trust and transparency between job seekers and companies with efficient credential verification systems.
Hyperledger is a blockchain technology that fulfills the need of stakeholders to exchange sensitive information with trust, security, and transparency. Hyperledger’s Fabric is a framework that can accelerate and simplify education-to-employment verification processes. It can enable educational institutions, students, and companies to collaborate and share information using a secure blockchain based application.
The Fabric enables blockchain developers to build distributed ledger solutions that provide increased privacy, flexibility, and scalability. It is an extensible blockchain platform that requires no native currency to run distributed applications.
It enables components like consensus algorithms and Membership Service Provider to be plug-and-play for the development of different use cases and trust models. In particular, the MSP component executes membership services with interoperability across different membership standards and architectures in a permissioned model.
With container technology, it runs smart contracts called “chaincode” for the automated execution of business rules in the system.
The Fabric also can also create private permissioned channels that enable a group of participants create a separate transaction ledger. It is important for private transactions where every participant in the network should not see them but only the permissioned ones.
A prototype platform based on Hyperledger can provide various operational benefits for the education-to-employment system. It can create and maintain self-sovereign digital proof of credentials including educational certificates and authority evidence of academic achievements. Concurrently, the digital proofs can bear timestamps for seamless integration with existing applications. It improves data integrity and protects the intellectual property rights of all stakeholders.
A Hyperledger Fabric based verification system will require the user’s private key to sign the content of the certificates and add a signature to it. It will create unique hash IDs that students, educational institutions, and employers can use to verify the contents of an educational certificate. As a result, users will use their private keys to create digital records and ensure consistency of information and certificate contents. Educational institutions can use their private keys to verify and sign digital certificates
Post that, smart contracts and multi-signatures will trigger to verify the certificate at each level of authorization.
Finally, the digital certificates will reach students or employees in near real-time.
The prototype system we discussed above has architecture layers as shown in the image below. The system uses blockchain as the underlying data storage mechanism. Hyperledger Fabric (Certificate Authority) enables Authorization services and Chaincode technology executes smart contracts as per the business logic. In addition, it provides various modules, such as for authority authentication, student information management, recruitment information, and block information. The system architecture also provides a web interface, and CLI (command line interface) to be used when it is necessary to customize the system from the bottom.

As visible in the image, users can authenticate their identities using a web interface. Further, they can obtain certificates from Hyperledger Fabric (CA) server with their private keys and passwords. Users, depending on their authorization, can request a query or edit information related to students or recruitment with the web interface and CLI.

Figure 3 shows the basic blockchain network architecture of a prototype solution deployed on Hyperledger Fabric. The solution uses two types of organizations, educational institutions and other organizations. Each organization comes with two Fabric based peer nodes to create the blockchain network. The network has a single-node orderer known as the Ordering services of the solution deployed in Solo Mode. In addition, it uses Hyperledger Fabric CA server deployed in a single node to provide membership services of educational institutions.

Hyperledger blockchain development services focus on eliminating a few pain points that currently hamper the education-to-employment system. They address the current information asymmetry existing between employer organizations and educational institutions. In addition, they also focus on enabling seamless convergence among students, employer enterprises, and educational institutions with transparency, authenticity, and validity of data. However, there are many other use cases and applications of Hyperledger Frameworks that can be explored, ranging from education to identity management to healthcare solutions.
