Blockchain is one of the most popular and important distributed and decentralized database. Due to the present technology all the people are focusing on online transactions. The first implementation of blockchain technology was the cryptocurrency. Crypto currencies allow people to store their money and make payments securely by using cryptographic techniques. So Blockchain provides greater infrastructure for transaction processing and, it can store and move transaction efficiently and more securely compared other traditional transactions. Over the network huge amount of data being processed for any transaction. During the transaction processing Authentication, Confidentiality and integrity are the most critical services in almost all current network applications. As everyone aware of that these services are managed by the centralized controller known as certificate-authority and are prone to attacks easily. So, providing a security to transaction processing becomes a critical challenging task. In this paper, we provided a blockchain based transaction processing using Flask to resolve the issues with centralization.
