➤Cryptography: The Hidden Power Behind Blockchain
When people hear “crypto,” they often think about coins, tokens, or trading. But the word “crypto” actually comes from cryptography, the technology that makes blockchains secure and trustworthy.
➜ what is cryptography?
Cryptography is the science of securing information by transforming it into a form that is unreadable to anyone except those who have the right key or method to decode it. It’s the science of protecting information using mathematics. Think of it as a digital lock and key system, designed so only the right person can unlock the right information.
It is a fundamental part of cybersecurity and is used to protect data in many areas, including:
➝ Online banking and shopping
➝ Secure communications, e.g., WhatsApp or Signal
➝ Digital signatures and authentication
➝ Blockchain and cryptocurrencies
