Technology
An Introduction to Decentralized
Digital Ledgers
What is Blockchain?
• • A blockchain is a distributed digital ledger.
• • It records transactions across many
computers.
• • Data stored is immutable and transparent.
• • Each record is called a block; blocks are
linked forming a chain.
Key Features of Blockchain
• • Decentralization: No central authority.
• • Transparency: All participants can view
transactions.
• • Immutability: Once recorded, data cannot be
altered.
• • Security: Cryptographic techniques ensure
data integrity.
How Blockchain Works
• 1. A transaction is requested.
• 2. The transaction is broadcast to a peer-to-
peer network.
• 3. The network validates the transaction using
consensus algorithms.
• 4. A new block is added to the chain in a
secure and immutable way.
Applications of Blockchain
• • Cryptocurrencies (e.g., Bitcoin, Ethereum)
• • Supply Chain Management
• • Healthcare Records
• • Voting Systems
• • Smart Contracts
• • Identity Verification
Challenges of Blockchain
• • Scalability
• • Energy Consumption
• • Regulatory Uncertainty
• • Integration with Existing Systems
• • Data Privacy
The Future of Blockchain
• • Growing adoption across industries.
• • Integration with AI and IoT.
• • Development of eco-friendly consensus
mechanisms.
• • Potential to revolutionize finance,
governance, and more.
