Digital Currency Mein Block Chain Technology"$"$"$"$

Block Chain Technology ek decentralized aur distributed ledger system hai jo transactions ko securely record karta hai. Yeh technology digital currencies, jaise Bitcoin aur Ethereum, ka backbone hai.

Digital Currency Mein Block Chain Technology Ke Features"$"$"$"$

1. Decentralization:
   • Traditional banking systems centralize data storage aur processing ko ek central authority ke control mein rakhte hain. Blockchain technology is model ko decentralize karti hai, yaani data ek single central point par store nahi hota, balki multiple nodes (computers) par distribute hota hai. Har node network ka ek copy rakhti hai.
2. Transparency and Immutability:
   • Blockchain par ki gayi transactions public ledger par record hoti hain, jo ki sab nodes ko visible hota hai. Yeh ledger immutability ensure karta hai, yani ek baar data enter hone ke baad usme tampering ya alteration nahi kiya ja sakta.
3. Security:
   • Blockchain mein transactions cryptographic techniques se secure hoti hain. Har transaction ko verify karne ke liye cryptographic hash functions use hote hain. Har block apne previous block ke hash ko include karta hai, jo chain ko secure aur tamper-proof banata hai.
4. Consensus Mechanisms:
   • Transactions ko validate karne ke liye blockchain different consensus mechanisms use karti hai, jaise Proof of Work (PoW), Proof of Stake (PoS), etc. Yeh mechanisms ensure karte hain ki network ke majority nodes agree karte hain ek valid transaction par.

Digital Currency Mein Block Chain Technology Ke Function"$"$"$"$

1. Transaction Initiation:
   • Jab koi user digital currency transfer karta hai, ek transaction create hoti hai. Is transaction mein sender aur receiver ka address aur transfer amount hota hai.
2. Transaction Verification:
   • Network par present nodes transaction ko verify karte hain. Verification ke liye nodes ensure karte hain ki sender ke wallet mein sufficient balance hai aur transaction valid hai.
3. Block Creation:
   • Verified transactions ko ek block mein group kiya jata hai. Har block ek unique hash generate karta hai aur apne previous block ka hash store karta hai.
4. Block Addition to Chain:
   • Consensus mechanism ko follow karte hue, naye block ko existing chain ke saath add kiya jata hai. Yeh addition permanent hota hai aur pehle se existing blocks ko alter nahi karta.
