A democratic election is a crucial event in any country. Therefore, the government of the country is concerned with creating more competitive and fairer elections. This paper discusses the survey and scope of Blockchain technology adoptions in conducting elections. A distributed digital ledger is used in the Blockchain technology that is utilized for recording transactions happening between two parties. Ledger conducts this processing in an efficient and effective manner with latest secure mechanism of encryption algorithms. Therefore, the data stored in several blocks in each transaction is secure, transparent, and tamper-proof, which ultimately improves the transparency and voter confidentiality. This paper demonstrates how the benefits of the Blockchain technology such as immutability, transparency and end-to-end verifiability can be utilized by the national governments around the world to ensure fair democratic elections. In short, we aim to present a rigorous mechanism of a Blockchain based e-voting system, its efficiency based on different consensus algorithms and the overall progress and analysis based on some critical parameters to anticipate the feasibility of the successful implementation of the proposed e-voting system.
