Socho agar aapka har financial transaction – jaise paisa bhejna, shopping karna, ya digital vote dena – bina kisi bank ya third-party ke ho, jo secure aur transparent bi ho? sunne me imposible lagega lekin ye sach hua hai Blockchain technology ki madad se.
Blockchain technology, crypto-currency, aur smart contracts ne poori duniya mein digital revolution la diya hai. Lekin fir bhi bahut log confuse hain –ye sab hai kya, kaise kaam karta hai.
Is blog mein, hum blockchain ko ekdum simple aur engaging tarike se samjhenge – bina technical words ko use kiye simple language me. Toh chaliye shuru karte hain!
Blockchain Technology Kya Hai?
Blockchain ek digital ledger (yaani ki digital register) hai jisme data secure aur transparent tarike se store hota hai.
Har ek block mein data hota hai, aur ye blocks ek chain mein jud jaate hain – isiliye iska naam hai Blockchain.
Key Features:
- Decentralized: yani Koi ek authority ya server isse control nahi karta.
- Immutable: yani Ek baar data add ho gaya, toh use badla nahi ja sakta.
- Transparent: yani Sab transactions publicly visible hoti hai.
💡 Simple Example:
Manlo ramesh ne Suresh ko 1 Bitcoin bheja. Ye transaction ek block mein record ho jayega. Jab network mein aur bhi transactions honge, isi trah naye blocks banenge. aur ye sab block ki ek chain banegi aur ek dusre me judte jaayenge. Har block previous block se linked hota rahega– isse data tamper yani change karna almost impossible ho jaata hai.
Blockchain Kam Kaise Karta Hai? step by step
1. Transaction Initiation
Koi user ek transaction start karta hai – jaise ki Bitcoin transfer karna.
2. Verification via Network
Transaction verify hota hai network ke thousands of computers (nodes) ke through. Ye decentralized verification hoti hai.
3. Block Creation
Valid transaction ek block ke form mein package hoti hai.
4. Block Link
Block ko cryptographic hashing ke through previous block se joda jaata hai.
5. Permanent Record
Ye block permanently blockchain mein add ho jaata hai.
🔐 Blockchain Technology Ki Key Features
