Fundamentally, blockchain enables programmable money – a concept that can transform the provision of welfare. Broadly, programmable money allows for payments to be made only if certain conditions are met. In this case, you can trigger payment if and only if the purchase is related to an Laptop.
This allows the creations of tokens that can only be used for a specified transaction and their usage generates a fully transparent and real time audit trail. The beauty here is that these tokens cannot be copied due to their cryptographic origin.
Most importantly, by using blockchain technology, the need for a bank account at the beneficiary level is obviated. The beneficiary only needs a phone and Aadhaar number. As discussed above, this would be major cost saving for the banks and a cash-flow win for the end beneficiary. This would also simplify benefit distribution in rural areas.
