  Blockchain technology ensures the integrity of QR code-based transactions by providing a decentralized and transparent ledger. Each transaction is recorded on the blockchain, which is a distributed network of computers. This means that once a transaction is recorded, it cannot be altered or tampered with. The use of QR codes in transactions allows for easy and secure transfer of information. When a QR code is scanned, it contains the necessary information to complete the transaction. This information is then verified and recorded on the blockchain, ensuring the integrity of the transaction.

  In simple terms, blockchain technology ensures the integrity of QR code-based transactions by creating a digital record that cannot be changed. When a QR code is scanned, the information it contains is encrypted and added to a block. This block is then added to a chain of other blocks, creating a permanent and unalterable record of the transaction. This decentralized nature of blockchain technology makes it nearly impossible for anyone to manipulate or tamper with the transaction data, ensuring its integrity.
