One of the most significant challenges encountered by electoral process is ensuring the integrity, transparency and accessibility of election systems, particularly in developing democracies where problems with trust, security and scalability remain a problem for both traditional and central electronic voting procedures. Blockchain technology has emerged as one potential solution to these challenges by providing decentralization, immutability, and cryptographic techniques, and consensus methods to analyze blockchain-based voting systems in-depth. Challenges to certain voting systems are discussed regarding their goals of voter authentication, ballot secrecy and verifiability, together done by introducing key cryptographic techniques. These techniques include digital signatures, hash functions, homomorphic encryption, and zero-knowledge proofs. Beyond technical research, the research looks at how the blockchain-based voting might be used in Bangladesh’s socio-technical and regulatory framework, paying special emphasis to new technology-assisted efforts for foreign voters. In addition, the inquiry evaluates the potential of blockchain-based voting being implemented in Bangladesh’s socio-technical regulatory framework, with particular focus on novel technology-aided solutions for overseas voters. The review identifies key research gaps in terms of scalability. usability, legal integration and public trust, and outline future directions for research that can support the context awareness and safe adoption of AI technologies. The primary objective of this study is to provide insight to scholars and officials on the benefits and drawbacks of blockchain-based voting system for advancing electoral security in Bangladesh. Although prototype implementation using Hyperledger fabric is developed to evaluate system feasibility, and performance metrics such as latency and throughput are analyzed under simulated voting conditions. Furthermore, a phased adoption roadmap is also suggested, and the technological, legal, and societal obstacles Bangladesh might encounter are covered
