Blockchain of Cryptocurrency Using a Proof-of-Work-Based Consensus Algorithm with an SHA-256 Hash Algorithm to Make Secure Payments

A blockchain is a distributed database featuring a decentralized digital network. A blockchain contains a set of data that can store information in blocks on an electronic platform in an advanced setup that uses a systematic framework via the Internet. Blockchains are popular because of their roles in cryptocurrency networks—such as Bitcoin—which must have a secure payment system. This method of transaction is perceived as an imaginative technique for online payments because it enables productive, straightforward, and secure exchanges. The blockchain of Bitcoin turned innovation into success by building a peer-to-peer monetary transaction network for secure transactions—a network that connects global financial markets with a circulated framework without any weak links.
The purpose of this research is to provide the best hybrid algorithm for cryptocurrency so that secure payments can be made. For example, because booking a hotel room reservation becomes complex when that hotel is located in other country. Currency exchanges and funds transfers have become expensive because of high exchange rates, so using cryptocurrency to make hotel room reservations is a cheaper option.
