SubConn

A Progressive Web App to track subsidized product transactions using distributed ledgers, hence improving efficiency and transparency in the distribution of goods and services through various Govt. schemes.

The algorithm includes a unique forward pass that integrates the tokens with the blockchain to allow for a back propagation to detect and handle errors. The block chain secures the item transactions and maintains the path followed by each item

Problem statement

  • The government spends $13.6 billion per year on the Public Distribution System(PDS)
  • With the total subsidies provided added up to a staggering Rs. 2400 billion.
  • These services do not reach the targeted people due to corruption in the system
  • This is clearly visible by the fact that 21% of the population still remain undernourished.

Solution

  • Tracking the products from the supplier to the consumer through the chain.
  • Eliminate tampering by middlemen.
  • Maintain quality control of the goods.

Tools and Platforms

  • Tagging each item using a QR Code
  • Development of a Progressive Web Application(PWA).
  • Secure and open database using NoSQL and Blockchain to prevent any tampering.
  • Aadhar API to validate and verify the agents and consumers.

Results

  • Reduce losses to 10%
  • Prevent theft by middlemen.
  • Good quality produce reaches targeted consumers.
