Abstract - With the blockchain technology garnering more and more attention in recent years, several apps have been created using it. Data integrity will therefore be preserved thanks to blockchain-based software solutions that use technology as their core component. When making decisions about a product's authenticity, the dispersed ensures through technology that consumers are completely free from the influence of businesspeople. Information is stored in blocks, each of which has a unique identity, in a system called blockchain. It links to other blocks that have a hash address, a link to the block after it, and a link to the hash address of the block before it. blockchain's security is mostly due to this feature. Blockchain technology is often described using the terms distributed, decentralized, and digital ledger. Because of blockchain technology, customers are no longer forced to rely on a third party to confirm the legitimacy of items. The objective of this project is to develop a web application that will help people figure out whether a product they want to buy is real or phoney. Block hashes of the product data will be kept in the programme, and a scanner made accessible by user login may be used to get the data about a product. Blockchain, a decentralized digital ledger, uses hash functions to create blocks that are linked together by the hash function of a previous block, creating a database that is impenetrable to manipulation.
