Study on Ethereum Transaction and Cancellation Using Blockchain Technology

Abstract

A Blockchain is a decentralized, distributed ledger that keeps track of transactions on numerous computers to prevent any changes from being made retrospectively without affecting all blocks after it and obtaining network consensus.\n\n\nA Blockchain eliminates the requirement for a reliable intermediary to mediate digital relationships. It enables safe and open record-keeping, and by streamlining procedures and lowering costs, it has the potential to upend a variety of businesses. A Blockchain has many important features, such as Decentralization: The network is not managed by a centralized body. A network of computers that collaborate to validate and record transactions instead maintains it. Once a transaction has been broadcast to the Ethereum network, it is typically impossible to undo it.\n\n\n
