A warm welcome to the Blockchain Technology and Applications course by Uplatz.

What is Blockchain?

Blockchain is a decentralized, distributed ledger technology that records transactions securely and transparently. It eliminates the need for intermediaries by enabling trustless transactions through cryptographic mechanisms.

Blockchain is revolutionizing industries by providing security, efficiency, and decentralization in digital transactions and processes.

How Blockchain Works

1. Transaction Initiation – A transaction is created and digitally signed by the sender.

2. Transaction Verification – Nodes (computers in the network) validate the transaction using consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS).

3. Block Formation – Validated transactions are grouped into a block.

4. Consensus & Block Addition – The new block is added to the blockchain through consensus protocols.

5. Immutable Ledger Update – The block is cryptographically linked to the previous block, making data tamper-proof and permanent.

Core Features of Blockchain

• Decentralization – No single authority controls the network.

• Immutability – Transactions, once recorded, cannot be altered or deleted.

• Transparency – Public blockchains allow anyone to verify transactions.

• Security – Cryptographic encryption ensures data integrity.

• Smart Contracts – Self-executing contracts automate processes.

• Consensus Mechanisms – Ensure transaction validation without intermediaries.

Real-World Applications of Blockchain

1. Cryptocurrency – Bitcoin, Ethereum for decentralized digital payments.

2. Supply Chain Management – Enhances transparency, reduces fraud in logistics.

3. Healthcare – Secures patient records, ensures data integrity.

4. Finance & Banking – Faster cross-border transactions, reduced fraud risks.

5. Voting Systems – Enables secure, tamper-proof digital elections.

6. Intellectual Property Protection – Tracks ownership and copyright securely.

7. Identity Management – Decentralized digital identity verification.

8. Real Estate – Streamlines property transactions and ownership records.

9. Gaming & NFTs – Ensures asset ownership and digital scarcity.

10. Government & Public Services – Transparent land registry, welfare distribution.
