This makes it hard for hackers to take over the whole system⁶. Being decentralized also means there are fewer weak spots, which can lead to problems like not working as promised or slow service⁶.

The consensus mechanism is key to blockchain’s security. It requires many nodes to agree on each transaction before it’s added to the ledger⁶. Blockchain uses networks that spread out data, making sure no one can change it without everyone agreeing. This keeps the data safe from unauthorized changes or tampering⁶.

With blockchain, you don’t need to trust each other because everyone has the same ledger. This stops any changes or corruptions from going through⁶. This makes the system secure and reliable, making it great for many uses, like in healthcare⁷, finance, and supply chain management⁸.

Even though blockchain is very secure, it has its own problems⁸. Decentralized blockchains are slower because each node has to check on things. But, the security blockchain offers is a big reason why companies want to use it for their systems⁸.

Centralized Systems	Distributed Systems	Decentralized Systems (Blockchain)
Single point of control and failure	Multiple points of control, but still centralized decision-making	No central authority, decisions made through consensus mechanism
High risk of data breaches and single-point failures	Reduced risk of single-point failures, but still vulnerable to attacks	Increased security through decentralization and consensus, reducing single points of failure
Inefficient and slow in responding to changes	More flexible and adaptable than centralized systems	Highly resilient and adaptable due to decentralized nature

“Blockchain technology is revolutionizing data security across various industries, extending beyond cryptocurrencies like Bitcoin⁸.”

The Privacy Paradox: Blockchain vs. Traditional Banking
