🔥 What is Blockchain Technology?

Blockchain is a decentralized and distributed ledger technology that records transactions across multiple computers securely and transparently. Each transaction is stored in a block, and once verified, it is added to a chain of previous transactions, creating an immutable and tamper-proof record.

Key features of blockchain include:

1. Decentralization – No single entity controls the data; it is maintained by a network of nodes.

2. Transparency – Transactions are visible to all participants.

3. Security – Data is encrypted and cannot be altered.

4. Smart Contracts – Self-executing contracts automate agreements without intermediaries.
