đ Crypto Basics Series #43: What Is Hashing?
đą 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.
---
âïž How Does Hashing Work?
Data â Hash Function â Hash
For example:
"HELLO" â "A1B2C3..."
Change the data:
"HELLO!" â "F8D9E1..."
The resulting hash can be completely different.
---
đ Why Is Hashing Important in Blockchain?
Hashing helps with:
- đŠ Linking blocks together
- đ Protecting data integrity
- đ§Ÿ Identifying blockchain data
- đ Detecting changes
- đĄïž Supporting blockchain security
Each blockchain can use different hashing algorithms and designs.
---
đĄ 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.
---
â ïž 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.
---
đŹ Question
What happens when the input data changes?
đ °ïž The hash can change completely
đ ±ïž The hash always stays identical
