Context- Gadchiroli uses blockchain caste certificates to deter forgery.
Concept-
- Bengaluru-based LegitDoc is powering a Maharashtra government initiative to issue 65,000 blockchain caste certificates in Gadchiroli district, which has about 70 per cent tribal population.
- The caste certificates are produced on blockchain to deter any forgery.
- LegitDoc will cryptographically commit selective details of every caste certificate from the ‘MahaOnline’ portal on the polygon POS blockchain and generate a unique QR code.
- These QR codes will consist of blockchain-proofs, which can be embedded on the certificate.
- Anyone who wants to cross-check can go to the verification portal on the district website and scan the QR code. The verification process takes less than ten seconds.
About Blockchain:
- Blockchain derives its name from the digital databases or ledgers where information is stored as “blocks’’ that are coupled together forming “chains”.
- It offers a singular combination of permanent and tamper-evident record keeping, real-time transaction transparency and auditability.
- A block is the “current” part of a blockchain which records some or all of the recent transactions, and once completed, goes into the blockchain as permanent database.
- Each time a block gets completed, a new block is generated. Blocks are linked to each other (like a chain) in proper linear, chronological order with every block containing a hash of the previous block.
- An exact copy of the blockchain is available to each of the multiple computers or users who are joined together in a network.
- Any new information added or altered via a new block is to be vetted and approved by over half the total users.
