🚀 Crypto Basics Series #43: What Is Hashing?
🔢 What Is a Hash?
A hash is a fixed-length string of characters generated from input data using a mathematical function called a hash function.
Even a tiny change in the original data can produce a completely different hash.
---
⚙️ How Does Hashing Work?
Data → Hash Function → Hash
For example:
"HELLO" → "A1B2C3..."
Change the data:
"HELLO!" → "F8D9E1..."
The resulting hash can be completely different.
---
🔗 Why Is Hashing Important in Blockchain?
Hashing helps with:
- 📦 Linking blocks together
- 🔐 Protecting data integrity
- 🧾 Identifying blockchain data
- 🔍 Detecting changes
- 🛡️ Supporting blockchain security
Each blockchain can use different hashing algorithms and designs.
---
💡 Simple Example
Think of a hash as a digital fingerprint for data.
If the original data changes, the fingerprint changes too.
That's why unexpected changes can be detected.
---
⚠️ Important
A hash is not encryption.
Encryption is designed so authorized users can recover the original information.
Hashing is generally designed as a one-way transformation where recovering the original input from the hash should be computationally difficult for a secure hash function.
---
💬 Question
What happens when the input data changes?
🅰️ The hash can change completely
🅱️ The hash always stays identical
