Data Protection with Blockchain

Ever wondered if...How does the often heard "blockchain" protect our data?

Many people may know blockchain from Krypto Kerrency, but this technology is actually much more useful than that, especially the over-the-top "information security." Today, we're going to take a closer look at how blockchain works and what it can use.

The Simple Working Principle of Blockchain

Imagine that a blockchain is a decentralized account book that does not store data on a particular computer, but is spread across a network. When new data is added, it is contained in a block, and each block is connected by a unique code called a hash, creating a continuous and secure data chain.

Why does blockchain help protect data?

* Decentralization: Data is not at the center, so there are no weaknesses that can be easily attacked by the poor. If you want to destroy data, you have to hack almost all the computers in the network at the same time, which is very difficult.

* Immutability: Once the data is saved in the block, it cannot be edited or deleted. If you want to change, you have to create a new block with the latest data and connect to the original block, allowing us to check the entire history of the change. The problem of data forgery is gone.

* Cryptography: Blockchain uses "hash" as the digital signature of each block. If the data in any block is edited, even a little bit, the hash will change immediately, allowing us to capture the forgery immediately.

* Transparency: For public blockchain, everyone in the network can access and monitor transactions, creating high transparency and reliability.

Interesting practical application example

Blockchains are deployed to protect data in many industries:

* Food Business: Record the Path of Goods from Farm to Consumer Hands, Prevent Counterfeits, and Build Confidence

* Medical: Securely store patient health history and share information between hospitals without fear of information leaking or being falsified.

* Vote: Record of votes, make election results transparent and verifiable; cannot be edited

* Intellectual Property: Use portfolio records to provide evidence of who owned the first one. Prevent theft of the portfolio.

Blockchain is therefore more than just a technology, but a powerful tool that helps maintain the security and reliability of information in the digital world.
