Sub: Implementation of Block Chain Technology for Board Exam Results Documents


In pursuit to achieve Digital Excellence, CBSE implements yet another “Emerging Technology” i.e. “Block Chain” for its results and academic documents. Recently CBSE also implemented Artificial Intelligence & Machine Learning for its totally digitized Affiliation System called SARAS (School Affiliation Re-Engineered Automation System).

Implementation of Block Chain Technology exam

CBSE in technical collaboration with Centre of Excellence for Block Chain Technology of National Informatics Centre under the Ministry of Electronics and Information Technology  (MeitY),  Govt.  of  India  has  developed  a  system  called  “Academic (Block Chain) Documents (ABCD)” which ensures that academic documents are recorded in a secure and tamper proof manner and can be accessed online through trusted and verifiable means. It has been established using Block Chain Technology to record the certificates in a linked chain structure.

Previously, verification of the authenticity of certificates produced by the candidates for admissions, jobs, loans etc. was a challenge. The genuineness of the certificate with the concerned universities or boards had to be thoroughly checked, and therefore the verification process required considerable effort and processing time. The Academic Block Chain Documents (ABCD) addresses these challenges by recording the data in a distributed ledger with ownership of all participating stakeholders. The data is recorded in the chain based on the consensus among the stakeholders and simultaneously replicated at all the locations in the distributed network of Block Chain nodes. This eliminates the dependency on a third party for verification. The data is linked and stored with cryptographic security so that it is immutable and traceable. The linking of the blocks in the block chain ensures that they cannot be tampered with, and the data is trustable as it can be verified across the participating stakeholders.

CBSE has already made available the digitally signed certificates of Class X and XII for years 2019-2021 and will gradually push the certificates of previous years in the next few months. Upon issuance of new certificates by CBSE, the digitally signed certificates will be sent to the Block Chain based system creating an additional secure link. This network is currently established with nodes at Bangalore, Pune and Jaipur. Presently, the Certificate Chain is managed by NIC at its data centres.

CBSE had earlier developed its own digital academic repository called ‘Parinam Manjusha’ in 2016. This repository has been integrated with NEGD’s (National e- Governance Division) Digital Locker platform. At present, result data of Class X & XII examinees of 18 years i.e., 2004 to 2021 has been made available online for students to download, and for verification by employers or higher education institutions. QR coded academic documents such as Marks Sheets, Migration Certificates and Pass Certificates are also available in this repository.

The Academic Block Chain Document can also be used for online counselling by the various institutes, by integrating their systems with plug-in interfaces. Banks and financial institutions can also use this system for sanctioning of educational loans and merit-based scholarship based on the qualifications of the applicants. One can verify the authenticity of the certificates even after several years of issuance, since a trail of all the insertions or changes made on a particular certificate will be provided.

Introduction of Academic Block Chain Document has resulted in a Transparent, Tamper Proof and Paperless usage of certificate. It has also substantially cut down the time for verification and reduced paperwork.

How to Use

1. All users viz. students, educational institutions, employers can verify academic documents by visiting or CBSE Main website

2. Click on “Verify” menu option on top menu bar available on home page.

3. Select the class from the pop up. Input basic details like Roll No, Date of Birth (in case of Class X only), Exam Year, Exam Type and Student Name (partial) and press ‘Go’ to confirm.

4. Once the details are validated, the marks statement (available presently) of the student is displayed.

It is expected from the Head of the Institution that the information regarding the Academic (Block Chain) Document (ABCD) will be communicated to all concerned.

Yours faithfully
