Backtesting is the process of evaluating an investment strategy or model using historical data to determine how it would have performed in the past. It allows investors to assess the effectiveness and reliability of a strategy before applying it in real market conditions. While positive backtest results do not guarantee future success, they can help identify weaknesses and optimize investment approach.

Bank bonds are debt securities issued by banks to raise funds from investors. The bondholder lends money to the bank for a fixed period, and in return, receives regular interest payments (coupons). At maturity, the bank repays the bond's nominal value. These bonds can be secured by the bank's assets or issued as unsecured, and they are used to finance banking operations or to increase liquidity.

Blockchain is a decentralized digital database that stores records of transactions in chronological order.
