What Is Blockchain Technology?

Blockchain is a distributed digital ledger that records transactions across multiple computers in a secure, transparent, and tamper-resistant manner.

Instead of storing information in a centralized database, blockchain distributes records across a network of participants.

Each transaction is stored in a block that is linked to previous blocks, forming a chain of records.

This structure creates:

• Transparency
• Security
• Immutability
• Traceability
• Decentralization

How Blockchain Works

Transaction Creation

A transaction is initiated by a user or system.

Examples include:

• Financial transfers
• Contract execution
• Asset tracking
• Data sharing

Validation Process

Network participants verify transaction legitimacy.

Block Formation

Validated transactions are grouped into blocks.

Chain Integration

New blocks are added to the blockchain in chronological order.

Distributed Storage

Copies of the ledger are maintained across multiple nodes.

This distribution improves resilience and security.
