🧱 Crypto 101: How Does Blockchain Work?
The backbone of every crypto project — but how does it really work? Let’s break it down 👇
---
🔗 1. What is a Blockchain?
A blockchain is a distributed digital ledger made up of a chain of blocks, where each block contains a batch of verified transactions.
Every time someone sends $BTC, $ETH, or any crypto — that transaction is recorded on a block.
---
⚙️ 2. Key Components of Blockchain:
✅ Block – Contains:
- List of transactions
- Timestamp
- Hash (unique fingerprint)
- Hash of the previous block
✅ Hash– A cryptographic code that uniquely identifies a block. Even a tiny change in the block changes the hash entirely. This prevents tampering.
✅ Consensus Mechanism– Rules that decide how new blocks are added.
- Proof of Work (PoW) – Miners solve puzzles (used by $BTC)
- Proof of Stake (PoS) – Validators are chosen based on staked coins (used by $ETH)
✅ Decentralization – Copies of the blockchain exist on thousands of nodes worldwide. No single point of failure.

🛡️ 3. Why Is It Secure?
- Immutability – Once a block is added, it can’t be altered without changing all blocks after it.
- Transparency – Anyone can view the ledger using block explorers.
- Trustless System – You don’t need to trust any middleman; the code enforces rules.

📌 Real Example:
When Alice sends 1 $BTC to Bob:
- The transaction is broadcast to the network
- Miners validate it and include it in a block
- The block gets added to the chain
- Bob sees the BTC in his wallet 📲
