First of all, When it's mentioned that Blockchain makes data practically unchangeable, it refers to the integrity of the data. Integrity means that the data remains secure and unchanged, and this is ensured by the special features of the blockchain, such as cryptographic encryption and decentralized consensus.
What is blockchain?
blockchain is a technical solution for managing data in a distributed infrastructure without the need for a central authority. This distributed structure allows transactions to be verifiable and tamper-resistant through consensus among participants.
For example, in the context of cryptocurrency payments, blockchain technology enables the verification of transactions without relying on a central authority, such as a bank. This fosters trust, as all participants can transparently verify transactions. The information stored in the blockchain is protected by advanced cryptographic methods, making it highly secure against manipulation
goals of blockchain technology at a glance:
- Immutable Data (Data Can't be Changed) : Once something is recorded in the blockchain, it stays that way. No one can secretly alter it.
- Transactions Transparent and Traceable for All Users (Everyone Can See and Understand Transactions) : All users can easily see and understand what's happening in transactions. It's like a clear window where everyone can peek in.
- Distributed, Consensual Data Storage Without a Central Authority (Data is Stored Everywhere, No Boss Needed): Information is saved in many places, and everyone involved agrees on what's happening. There's no big boss controlling everything. It's like a team effort where everyone has a say.
In short, blockchain offers secure, unchangeable data, transparent transactions, and decentralized storage, fostering trust and innovation across various applications.
