CBSE BlockChain technology in Exam result 2021-2022

In pursuit to achieve Digital Excellence, CBSE implements yet another “Emerging Technology” i.e. “BlockChain” 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).

CBSE in technical collaboration with Centre of Excellence for Block Chain Technology
of National Informatics Centre under the Ministry of Electronics and InformationTechnology (MeitY), Govt. of India has developed a system called “Academic
{BlockChain} 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 BlockChain 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 BlockChain 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.
