A blockchain is used to store exam results of students at a university. Assume that the Hash of each block is determined using the following formula:
A = ASCII value of the second letter of the course prefix (see the lookup table below)
B = ASCII value of the first letter student's public key
C = ASCII value of the Grade
Nonce = Value between 1 and 5 that makes the hash divisible by 5
Hash = A + B + C + Nonce - Value of the last two digits of the Previous Hash
The initial Hash of the Blockchain is 415
Add the following 4 transactions to the blockchain, and determine the correct Nonces and Hashes. Enter the Nonces and Hashes in the table below.
