🔍 What is Blockchain?
Blockchain is a decentralized digital ledger technology that records transactions across multiple computers. It's the backbone of cryptocurrencies like Bitcoin and Ethereum, but its applications extend far beyond finance.
- Key Features:
- 🔄 Decentralization: No central authority controls the network.
- 🔒 Immutability: Once data is added, it cannot be altered.
- 🧩 Transparency: All transactions are visible to participants.
🛠️ How Does Blockchain Work?
- Blocks Creation: Data is grouped into blocks with timestamps and cryptographic hashes.
- Chain Linking: Blocks are linked in a chain using hashes, creating a secure sequence.
- Consensus Mechanism: Nodes validate transactions (e.g., Proof of Work, Proof of Stake).
📈 Applications of Blockchain
- Finance: Cryptocurrencies, smart contracts, DeFi platforms.
- Supply Chain: Tracking products from origin to consumer.
- Healthcare: Secure patient data sharing.
- Voting Systems: Transparent and tamper-proof elections.
