Blockchain bohat se blocks par mushtamil hoti hai
Har block mein:
Transactions ka data
Time & date
Pichlay block ka link (hash)
Is tarah ye chain ban jati hai → Block + Block + Block = Blockchain
Blockchain ki main khasiyaten:
Decentralized – Data kisi aik company ke paas nahi hota
Secure – Data change karna mushkil hota hai
Transparent – Sab transactions public hoti hain
Trustless – Beech mein kisi third party ki zarurat nahi
Blockchain ka use kahan hota hai !
Cryptocurrency (Bitcoin, Ethereum, XRP)
Smart Contracts
Banking & Payments
Supply Chain
NFTs
Voting Systems
Example:
Agar aap Bitcoin send karte ho
➡ transaction ek block mein record hoti hai
➡ network verify karta hai
➡ block chain ka hissa ban jata hai
➡ koi bhi usay change nahi kar sakta
