blockchain kya hoti hai sabse asaan bhasha me samjhe

Blockchain ek decentralized digital ledger hoti hai jisme transactional data records secure tarike se store hote hain.

Ye technology cryptocurrencies jaise Bitcoin ke piche hoti hai, lekin ise dusre domains mein bhi istemal kiya jata hai.

Blockchain ki sabse badi visheshta yeh hai ki ye centralized authority ya third-party ki zarurat nahi hoti.

Isme transactional data blocks ke form mein organize hote hain aur har block, pehle ke block se cryptographic tareeke se link hota hai. 

Har naya block ek unique hash code ke saath purane blocks ke sath jura jata hai, isse puri chain ban jati hai, jise hum blockchain kehte hain.

Jab koi transaction blockchain mein hoti hai, toh wo network ke sare participants ke saath share hoti hai aur unki approval ke baad hi validated hoti hai. 

Ek baar validation ho jane ke baad, transaction permanence mil jati hai aur usey wapis badalna ya delete karna mushkil ho jata hai.

Blockchain ka upyog data integrity, transparency, security aur trust ke liye hota hai. Kyunki data sabhi participants ke saamne openly available hota hai 

aur har change ko approve karna hota hai, isliye isme fraud kam hota hai aur hacking ka risk bhi kam hota hai.

Blockchain ke use cases bahut sare hain, jaise cryptocurrency transactions, supply chain management, voting systems, smart contracts, identity verification, 

aur financial services. Iski popularity tezi se badh rahi hai kyunki yeh ek secure aur transparent method hai jisme trust aur accountability ko promote kiya jata hai.
