The immutability of blockchain data makes it resistant to fraud and tampering from "summary" of Blockchain Technology Explained by Alan T. Norman
Blockchain technology is built on the principle that once data is recorded on the blockchain, it cannot be altered or deleted. This concept is known as immutability, and it is one of the key features that make blockchain resistant to fraud and tampering. Immutability ensures that the data stored on a blockchain is secure and tamper-proof. Once a transaction is added to a block and confirmed by the network, it is cryptographically linked to the previous block, forming a chain of blocks that are interconnected. Any attempt to alter the data in a block would require changing all subsequent blocks in the chain, which is practically impossible due to the decentralized nature of blockchain networks. This means that once a transaction is recorded on the blockchain, it is there to stay, providing a reliable and transparent record of events. This feature is particularly valuable in industries where data integrity is critical, such as finance, healthcare, and supply chain management. The immutability of blockchain data also enhances trust among participants in a blockchain network. Since all parties can verify the integrity of the data independently, there is no need for a central authority to oversee transactions. This decentralized and trustless nature of blockchain technology eliminates the risk of fraud and manipulation, making it an ideal solution for secure and transparent digital transactions.- The immutability of blockchain data plays a crucial role in ensuring the security and integrity of the information stored on a blockchain. By making data resistant to fraud and tampering, blockchain technology provides a reliable and transparent platform for a wide range of applications.
