Blockchain ek aisi digital technology hai jisme jankari ko blocks me band karke ek chain ki tarah joda jata hai. Bitcoin isi technology par bana hai, lekin iska istemal crypto se kahin aage tak hai.
Simple Shabdon Me Samjhein
Sochiye ek aisa register (bahi-khata) jo hazaaron computers par ek saath maujood ho. Koi ek vyakti ise badal nahi sakta, kyunki badlav ke liye sabhi copies me ek saath badlav karna hoga — jo lagbhag namumkin hai.
Blockchain Kaise Kaam Karta Hai
- Koi transaction hota hai (jaise A ne B ko paise bheje)
- Ye transaction ek block me jod diya jata hai
- Network ke computers (nodes) is block ko verify karte hain
- Verify hone par block chain me jud jata hai — hamesha ke liye
- Ek baar judne ke baad ise badla ya mitaya nahi ja sakta
Blockchain Ki Khaas Baatein
| Gunn | Matlab |
| Decentralized | Koi ek malik nahi, network sab chalate hain |
| Transparent | Har record sabke liye dikhai deta hai |
| Immutable | Ek baar likha record badla nahi ja sakta |
| Surakshit | Cryptography se har block surakshit rehta hai |
Blockchain Ka Istemal Kahan Hota Hai
- Cryptocurrency: Bitcoin, Ethereum jaise coins isi par chalte hain
- Supply chain: Samaan kahan se aaya, track karna aasan
- Banking: Tez aur saste international payments
- Healthcare: Patient records surakshit rakhna
- Voting: Pardarshi digital matdaan ke prayog
Blockchain Vs Aam Database
Aam database ek company ke server par hota hai aur uska malik use badal sakta hai. Blockchain hazaaron computers par banta hai aur koi akele ise badal nahi sakta — isi se is par bharosa banta hai.
