Karnataka, which has a long history of technological and innovative leadership, is currently significantly investing in the possibilities of blockchain technology. Polygon has announced the adoption of LegitDoc, a blockchain-based certification system, on the Polygon Blockchain by KSDC, an organisation under the Government of Karnataka, an Indian state. This is the first time the Karnataka government has officially implemented a blockchain. One of the key applications of LegitDoc is the creation of a new certificate issuance system that prevents unauthorised changes to KSDC graduates’ certificates. This will allow graduates to receive tamper-proof certificates. Furthermore, the LegitDoc Verifier DApp on the Polygon network may instantly check the certificates for any manipulation to certify their legitimacy.
