Abstract: This paper gives the complete overview of working of bitcoin and what are the problems will it face in the near future? It depicts the difference between the proposed theoretical architecture and current practical implementation of secure hash algorithm. The reason for proposing alternative secure hashing algorithm called SHA-512 replacing the most successful SHA-256 hashing algorithm is the evolution of quantum computers which has an ability to crack the hashing algorithm.
