Academic {BlockChain} Documents (ABCD)

    CBSE has taken many pioneering IT initiatives particularly in the domain of Examination. In last six years many landmark IT systems have been developed inhouse and implemented for various functions and stakeholders of the Board. Various IT systems have been developed with the focus on the following: -

  • 1. Minimum Govt. maximum governance
  • 2. Ease of Doing Business(EoDB)
  • 3. Ease of Living (EoL)
  • 4. Reduce compliances
  • 5. Data driven decisions
  • 6. Light but tight framework.
  • 7. Transparency
  • 8. Accountability
  • 9. No data redundancy
  • 10. Integrated systems
  • 11. Quick disposal

    Whenever and wherever required National Informatics Centre (NIC) & NeGD, Ministry of Electronics and Information Technology (MeitY),Govt of India have extended best possible technical support to the CBSE. CBSE’sAcademic Documents Chain has also been developed in technical collaboration with NIC..


    Post declaration of results, there are two challenges, (i) instant availability of digital academic documents & (ii) verification of these documents for admission process for higher education in India & abroad and selection of the candidates for the jobs. To address this, CBSE developed first of its kind its own digital academic repository called ‘Parinam Manjusha’ and launched 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 eighteen(18) years i.e. 2004 to 2021 is available online for downloading of digital academic documents by students and verification by employers and higher education institutions. Approximately 12 crore digital real time generated, digitally signed and PKI based QR coded academic documents such as Marks Sheets, Migration Certificates and Pass Certificates are available in this repository.

    Digitization of legacy records of Class X & XII from 1975 onwards is in progress and will be appended to the repository as soon as completed. Thereafter, thisrepository is set to become one of the largest digital academic repositories in the world.

    One of the challenges faced in the admission process for higher education in India & abroad and selection of the candidates for the jobs, is the verification of the academic documents produced by the candidates. The verification of the correctness and genuineness of these documents with the concerned universities or boards requires considerable effort and processing time. Hence most of the times, the institutes and companies insist on production of the original documents by the candidates.

    In order to adopt another online technology-based secured verification of digital academic documents, CBSE in technical collaboration with National Informatics Centre, Ministry of Electronics and Information Technology (MeitY), Govt of India has come up with a solution using Blockchain Technology named as “Academic {BlockChain} Documents(ABCD)”. This Blockchain ensures that academic documents are recorded in secured and tamper proof manner. These academic documents are accessed online by any one in trusted and verifiable manner. To begin with digital academic documents of examination 2019, 2020 & 2021 have been put under this Blockchain.

Academic {BlockChain} Documents(ABCD)& its features

First Example picture

    Academic {BlockChain} Documents (ABCD)’ has been established using the Blockchain Technology to record the academic documents of CBSE, by linking them like a chain. This Chain records the Academic Documents in a distributed manner in multiple locations. Academic Documents in this chain are secured, tamper proof and immutable. Attempt to tamper the data is not possible as all the distributed locations need to be updated as per the agreement to synchronise the data between them.

    Blockchain Technology records the data in the distributed ledger with all the participating nodes. The data are recorded in the Blockchain based on the consensus among the nodes and simultaneously at all the locations in the distributed network of Blockchain nodes. This eliminates the dependency on the third party for verification. The data are linked and stored with cryptographic security so that they are immutable and traceable. The linking of the blocks in the Blockchain ensures that they cannot be tampered with. The data are trustable as they can be verified across the participating nodes.

Usages of Academic {BlockChain} Documents

Second Example picture

    ThisBlockchain provides the trustable, immutable and traceable academic documents. It can be used by the various educational institutes for admission for higher studies and companies for job offers. It can also be used for the online counselling by the institutes. The financial institutions can also use this system for sanctioning of educational loans and other loans based on the qualification of the applicants. It is transparent, tamper proof, paperless and no dependency on third party.


I. There are two ways to verify the academic documents –

       (i) By accessing the portal and entering the basic details of the student like roll number etc. for viewing the academic documents.
       (ii) The institutes can register with the CBSE and use the bulk verification tool and API based verification modes.

II. Users of Academic {BlockChain} Documents

              Academic {BlockChain} Documents(ABCD)’ provides the mechanism for the educational institutes and companies to verify online the details of the claims of the applicants, who apply for the higher education or job. It also helps in counselling process, by integrating the systems with plug-in interfaces.
Main users of this chain are;
