⛓️Block Chain

Blockchain is a decentralized digital ledger that records transactions across a network of computers, ensuring security, transparency, and immutability. Unlike traditional databases controlled by a single entity, blockchain operates on a peer-to-peer network, meaning no central authority governs it.

How Blockchain Works:

1. Blocks & Transactions – Each transaction is grouped into a "block" containing data like sender, receiver, and amount.

2. Cryptographic Security – Blocks are encrypted using complex algorithms, making them tamper-proof.

3. Consensus Mechanisms – Transactions are verified by network participants (miners or validators) through methods like Proof of Work (PoW) or Proof of Stake (PoS).

4. Immutable Ledger – Once a block is added to the chain, it cannot be altered, ensuring trust and transparency.

5. Decentralization – No single entity controls the blockchain, reducing risks of fraud or manipulation.
