Blockchain on integrity

Even with more money being spent on cybersecurity, many organizations are still reluctant to use public cloud solutions. It is a common practice to apply encryption to the data going to the cloud, but encryption can only provide solid confidentiality against internal attacks; it can't protect data from corruption caused by configuration errors, software bugs, or espionage attempts. Although blockchain technology has its own solid approach to achieving immutability with the hashing algorithm and the Merkle tree model for integrity, we have to try and understand how it would practically work with real-world applications and Hyperledger Fabric.

Integrity in the current blockchain network

Integrity is a way of avoiding any tampering with the data. Blockchain uses cryptographic hashing to ensure that the ledger remains tamper-proof. One of the key characteristics of this hashing function is that it is always one-way, which means it is logically impossible to get the data...
