Immutability

Immutability refers to the unchangeable nature of data once it’s been recorded on a blockchain. Once a transaction is validated and added to the ledger, it cannot be altered or deleted. This is a core feature of blockchain technology, ensuring transparency, integrity, and trust in decentralized systems.

Why Immutability Matters

Immutability is crucial for preventing fraud and tampering. Since blockchain data is stored across many nodes and secured by cryptographic algorithms, changing even a single transaction would require altering the data on the majority of the network—an extremely difficult and costly task.

Real-World Impact

Thanks to immutability, blockchain is being adopted for applications like supply chain tracking, financial auditing, and secure recordkeeping. It builds a reliable history that cannot be manipulated, helping to establish long-term trust among participants.
