What is a Blockchain-based Digital Certificate?

A blockchain-based Digital Certificate is a digital form of certification stored on the blockchain, such as educational documents, that utilizes blockchain technology to ensure authenticity and prevent forgery. By leveraging the inherent security features of the blockchain, these certificates become almost impossible to counterfeit.

The blockchain acts as a decentralized ledger, recording each certificate’s issuance and ownership details, providing transparent and tamper-proof blockchain traceability. This approach significantly streamlines the verification process, allowing institutions, employers, or other relevant entities to quickly and reliably verify the authenticity of these digital certificates, thereby ensuring the credibility of educational achievements and other forms of accreditation.

How Does a Blockchain-based Digital Certificate Work?

Blockchain is a decentralized ledger that contains many transactions. These transactions are stored in blocks that are cryptographically chained together. As a result, there is no way to change any stored information since that would require manipulating every block. 

Four prominent parties are involved in the working process of a blockchain-based digital certificate: issuer, recipient, blockchain, and the certificate system. Digital certificates are issued through the certificate system, the credential platform. The certificate system is responsible for verifying data.

Below is how blockchain-based digital credentials work:

  • The issuer (organization) issues a digital certificate to the recipient using the certificate system. The certificate contains a unique ID unique to the recipient, and the credential is stored on the blockchain. 
  • The certificate is safely stored on the blockchain with the content cryptographically hashed. Certificate validation can only be completed by accessing the blockchain. 
  • The recipient receives a notification from the credentialing platform that contains the certificate and unique ID.
  • Signing into the digital credential platform allows recipients to view their credentials. Verifiers must have that unique ID or cryptographic hash to verify a credential.

How to Check a Certificate’s Validity?

Blockchain technology makes credential verification seamless and fast. Digital credential verification is accomplished by accessing the blockchain using the hash, QR code, or unique ID. For instance, to verify the authenticity of a certificate, an employer signs into the system after receiving a unique code or hash from a job applicant.

What Are The Benefits Of Blockchain-based Digital Certification?

Leveraging blockchain-based digital certificates provides businesses, organizations, and individuals several benefits. These benefits include:

  • Transparency
  • Accuracy
  • Reliability
  • Improved traceability
  • Improved security
  • Cost-effective verification
