⛓️ How Blockchain Really Works
Blockchain is the backbone of cryptocurrency. Let's break it down in complete detail.
The Architecture of a Block:
text┌─────────────────────────────┐ │ BLOCK HEADER │ ├─────────────────────────────┤ │ • Previous Block Hash │ │ • Timestamp │ │ • Nonce │ │ • Merkle Root │ │ • Difficulty Target │ │ • Version Number │ ├─────────────────────────────┤ │ TRANSACTION DATA │ ├─────────────────────────────┤ │ • Transaction 1 │ │ • Transaction 2 │ │ • Transaction 3 │ │ • ... │ │ • Transaction N │ └─────────────────────────────┘
Step-by-Step Process:
Step 1: A user initiates a transaction (e.g., sending Bitcoin)
Step 2: The transaction is broadcast to the network
Step 3: Network nodes validate the transaction
Step 4: Verified transactions are grouped into a block
Step 5: Miners/Validators compete to add the block
Step 6: The winning miner adds the block to the chain
Step 7: The block is permanently recorded and distributed
Step 8: The transaction is confirmed and complete
