CBSE collaborated with the Centre of Excellence for Blockchain Technology of National Informatics Centre under the Ministry of Electronics and Information Technology (MeitY) to create the Academic BlockChain Documents (ABCD) software.

Blockchain technology records the data in a distributed ledger with the 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 blockchain nodes.

This eliminates the dependency on a third party for verification. The data of the last three years starting from 2019 has been recorded in this and the other data of previous years will be uploaded gradually. In 2016, CBSE was the first to develop its own academic repository named ‘Parinam Manjusha’.

This network is established with nodes at Bengaluru, Pune and Jaipur. Presently, the certificate chain is managed by NIC at its data centres.

The result certificates are kept in a distributed manner at different locations involving multiple stakeholders, protecting them against any attempt of tampering, under this technology, officials said.

“Blockchain implementation has been done by CBSE. Earlier we introduced Artificial intelligence (AI) and Machine learning (ML) for affiliation systems. Here, the data is linked and stored with cryptographic security so that it is immutable and traceable,” CBSE Director of Information and Technology Antriksh Johri told news agency ANI. “This will serve as a single source truthful data for verification for students going for higher education or employment.”
