SecureCheque: A Blockchain-Driven Framework for Automated and Fraud-Resistant Cheque Clearance
Abstract
Even with the rise of fast digital payment systems, cheques have not disappeared from real-world financial use. They are still commonly used in situations where written authorization and delayed processing are required. However, the way these cheques are handled has remained mostly unchanged for years. The process usually moves through several steps involving differ- ent banking entities, and each step adds time and dependency. Because of this, completing a single cheque transaction can take longer than expected, especially when verification is done manually. A noticeable drawback in the current approach is how transaction information is stored and checked. Since records are maintained separately by different systems, there is no simple way to confirm the history of a cheque in one place. This makes it harder to detect if the same cheque data has already been used or slightly modified. In addition, users submitting cheques are often left without clear updates until the process is finished, which reduces visibility into what is happening in between. Instead of treating each transaction as an independent entry, the system described in this work connects records in a continuous sequence. Each new entry depends on the previous one, forming a structure where earlier data cannot be quietly changed without affecting what comes after it. A hash value is created for every record so that even a small change produces a different outcome, making inconsistencies easier to notice. The system accepts cheque details through a simple interface and checks whether similar information already exists before allowing it to be recorded. If the data is found to be repeated or inconsistent, it is not accepted. Otherwise, it becomes part of the sequence. This avoids unnecessary duplication and keeps the stored data consistent over time. Since all entries are linked, reviewing past transactions becomes more straightforward. Testing with different inputs showed that the system responds quickly and produces consistent results. The need for repeated manual verification is reduced, and the structure of stored data makes checking easier. While the current version focuses on basic validation and recording, it can be extended to work alongside existing banking processes. This approach does not try to completely replace current cheque systems but instead improves how transaction data is handled and verified. By organizing records in a connected manner and reducing reliance on manual checks, it offers a more reliable and transparent way to manage cheque clearance.
