What is Blockchain? (Hinglish Me Full Explanation)
Blockchain ek digital ledger (notebook) jaisa system hota hai jisme transactions secure, transparent aur permanent form me store hoti hain. Ye decentralized system hota hai jisme data kisi ek server par nahi, balki duniya bhar ke computers me distributed hota hai.
Blockchain Kya Hota Hai?
Simple words me, blockchain ek public, secure aur immutable digital record hota hai. Har transaction block ke form me store hoti hai aur saare blocks chain ki tarah interconnected hote hain.
Blockchain Ki 3 Main Features
- Decentralization: Koi ek company ya bank control nahi karta.
- Transparency: Transactions publicly visible hoti hain.
- Security: Cryptography se har transaction locked hoti hai — change karna impossible.
Blockchain Kaise Kaam Karta Hai? (Step-by-Step)
Step 1: Transaction Initiate Hoti Hai
Example: A ne B ko crypto bheja.
Step 2: Network Par Broadcast Hoti Hai
Transaction saare nodes (computers) ko bheji jaati hai.
Step 3: Nodes Verify Karte Hain
Nodes check karte hain ki transaction genuine hai ya nahi.
Step 4: Block Me Add Hoti Hai
Verified transactions ek block me save ho jaati hain.
Step 5: Block Chain Se Connect Ho Jaata Hai
Har block previous block ke saath connect hota hai — isliye iska naam Blockchain hai.
Blockchain Example (Real-Life)
Socho ek school register jisme sare marks likhe hote hain. Ek baar entry ho gayi toh koi change nahi kar sakta. Blockchain bilkul aisa hi kaam karta hai — secure aur permanent.
