Blockchain technology ensures data integrity by encrypting information across a network of nodes from "summary" of Blockchain Technology Explained by Alan T. Norman
Blockchain technology is designed to ensure data integrity by employing encryption techniques that secure information across a network of nodes. This network of nodes acts as a decentralized system where each participant holds a copy of the blockchain ledger. Each block in the chain contains a unique cryptographic hash that links it to the previous block. This creates a chain of blocks that are immutably linked together, making it nearly impossible to alter or tamper with the data. When a new block is added to the blockchain, it undergoes a process of validation by the network of nodes. This validation process involves solving complex mathematical puzzles that require significant computational power. Once a block is validated, it is added to the blockchain, and the information it contains is considered secure and immutable. Because each block is linked to the previous block through cryptographic hashes, any attempt to alter the data in one block would require changing all subsequent blocks, which is computationally infeasible. The encryption techniques used in blockchain technology ensure that data stored on the blockchain is secure and tamper-proof. Each block contains a hash of the previous block, creating a chain of blocks that are cryptographically linked. This cryptographic linkage prevents any unauthorized changes to the data stored on the blockchain. Additionally, each block contains a timestamp, making it possible to trace the history of transactions and verify the integrity of the data. By distributing the blockchain ledger across a network of nodes, blockchain technology eliminates the need for a central authority to verify transactions. Instead, transactions are validated by the consensus of the network, ensuring transparency and security. This decentralized nature of blockchain technology makes it resistant to tampering and fraud, as any attempt to alter the data would require the consensus of the majority of nodes in the network.- Blockchain technology leverages encryption techniques to ensure data integrity by securing information across a network of nodes. This decentralized system creates a tamper-proof ledger that is transparent, secure, and resistant to unauthorized changes. Blockchain technology is revolutionizing the way data is stored and verified, offering a secure and efficient solution for a wide range of applications.
