🎷Safety

By getting rid of the need for a central authority, one cannot simply change any network feature to its benefit. The use of encryption ensures another layer of security for the system. But how to offer so much security compared to existing technologies?

Well, it is extremely safe offers a special disguise – encryption. In addition to decentralization, encryption establishes another layer of protection for users. Encryption is a fairly complex mathematical algorithm that acts as a firewall for attacks. All information on the blockchain is encrypted with hashed. In simple terms, the information on the network hides the true nature of the data. For this process, any input data goes through a mathematical algorithm that produces a different type of value, but the length is always fixed.

You could think of it as a unique ID for all data. All blocks in the record book come with a unique hash and contain the hash of the previous block. Thus, changing or attempting to tamper with the data will mean changing all hash IDs. And that's kind of impossible. You will have a private key to access the data, but you will have a public key to make transactions.

Irreversible

The hash is quite complex and it is impossible to change or reverse it. No one can take a public key and invent the private key. Also, a single change in input can lead to a completely different ID, so small changes are not a luxury in the system.

If someone wants to corrupt the network, they will have to change all the data stored on each node on the network. There could be millions and millions of people, where everyone has the same copy of the book. Accessing and hacking millions of computers is almost impossible and costly.

That's why it's one of the main features of blockchain technology. As it's very hard to ignore, you won't have to worry about hackers taking all your digital assets from you.
