Blockchain VS Digital Certificate

A digital certificate is even known as a public key certificate. It gets used to cryptographically link ownership of a public key with the entity that possesses it. The purpose of digital certificates is to share the public keys to get used for encryption and authentication.

Digital certificates encompass the public key getting certified, identifying information related to the entity that owns the public key. It also reveals the metadata relating to the digital certificate and includes a digital signature of the public key that the certificate issuer produced.

The digital certification procedure is mainly automated. Once you encrypt communications, digital certificates protect sensitive data and avert the information from being witnessed by the ones unauthorized to view it. This technology guards companies and individuals against having massive of sensitive data.

However, attackers or hackers can hack digital certificates like any other security deterrent. The most logical and rational way for a mass hack is in case the issuing digital CA gets attacked and hacked. It enables notorious people to penetrate the source of digital certificates the authority owns.

Blockchain is Beyond Digital Certificate

Blockchain technology provides a new, even more, advanced infrastructure to promise, share and confirm the training and skills acquired. Every certificate includes references of the issuer as well as the receiver. It even includes the document’s signature (hash), which stays stored in a public database (the blockchain) and is indistinguishable on thousands of computers worldwide. It can easily ensure security for data, documents and certificates through QR codes.

Nobody can Forge Certificates

With blockchain, it is possible to confirm with certainty that the certificate was initially received and issued by the same people mentioned in the certificate.

Easy Verification

Anyone can verify the document or certificate with access to the internet. You can put a blockchain secured QR code on the certificate that will reveal the authenticity of the certificate. Once you have scanned the QR code, the authentic data reveals. Hence, no scope for forgery. There is be no need for any third-party intervention in the verification.

Keeping in mind the absence of intermediaries to authenticate the certificate, you can verify it even if the organization that issued it no longer exists or has no access to the issued document or record.

On the other side, digital certificates can authenticate or verify a document. But it takes a lot of time to authenticate digital certificates and encrypt and decrypt. You might find it frustrating to wait extensively.

Destruction is Merely Impossible

One can destroy the registry of certificates issued and received in a blockchain. But it is possible only if every single of the existing copies gets destroyed in thousands of computers that host the blockchain technology. This deed is merely impossible.


Blockchain technology solutions are easily integrated. For example, you can implement document or certificate security QR codes without hassle. It would seamlessly integrate and ensure utmost security.

But digital certificates are not at all standalone technology. They should be appropriately integrated with systems, data, applications, networks and even hardware to be productive. It is not at all a tiny task.

The Bottom Line

Blockchain and digital certificates both can be effective for your organization. You can avoid the intermediaries for verification and virtually verify anything in no time. The qr code authentication system will ensure efficiency and secure sharing through QR codes. Learn more about this technology with ProofEasy.
