3. Exit

Upon entering choice 1, details of donor is taken along with the details of organization and amount.

As soon as the transaction is done from donor end, zeroknowledge() is called to verify identity, after which the block is added to the Blockchain, Block is mined to set the hash with difficulty , and finally verify Transaction is called to confirm all blocks are mined and their hashes are also accurate.

If choice 2 is selected transaction history of the donor is displayed asking for a donor ID. The transactions are displayed with the following details.
