Abstract
The rapid growth of digital banking has improved convenience and accessibility but has also introduced significant security challenges, including phishing attacks, data breaches, OTP interception, and unauthorized transactions. Traditional banking systems rely heavily on centralized databases and token-based authentication mechanisms, which remain vulnerable to various cyber threats. This paper proposes a tokenless blockchain-based secure transaction framework that employs digital signatures and a permissioned blockchain ledger for authentication and transaction validation. The proposed system eliminates dependency on OTPs and external communication networks while ensuring transparency, immutability, and tamper-resistant transaction records. SHA-256 hashing is used to secure transaction blocks, and only authorized banking nodes participate in the validation process. Experimental implementation demonstrates improved security, enhanced auditability, and greater reliability compared to conventional banking systems.
Keywords: Blockchain, Digital Banking, Tokenless Authentication, SHA-256, Digital Signatures, Secure Transactions.
