IICERTIFIED BLOCKCHAIN EXPERT - CBE BLOCKCHAIN ANALYSIS USE-CASE Scenario Fixed Deposit One of the retail banks in Bahrain, XYZ Bank, discovered that their fixed deposit certificates were being forged and copied allowing bad actors to mis-use them for government transactions. Some of the actors were using fake fixed-deposit certificates to open new commercial entities and getting their CR's approved from these fixed deposit certificates. Bank XYZ is now considering to use innovative technologies that can help lower the rates of fraud in fixed deposit methods in forging certificates, and in the case any such methods are used, it would be detected by the central bank where those actors would be discovered. Please describe how a blockchain solution can be used by the central bank to help address this issue
