What is Blockchain?
Blockchain is a distributed digital ledger technology that records transactions across a network of computers. It creates a chain of data blocks, each cryptographically linked to the previous one, ensuring transparency, security, and immutability of information.
Core Components of Blockchain Technology
Blockchain is a decentralized, immutable ledger that records transactions across a network of computers. Its key features include:
- Permanent records: Data blocks are cryptographically secured, preventing tampering.
- Shared visibility: All network participants access the same real-time data, reducing reconciliation needs.
- Smart contracts: Self-executing agreements automate processes like payments or compliance checks
Tokenization of Assets
Tokenization converts physical or digital assets (e.g., real estate, bonds) into blockchain-based tokens, enabling:
- Fractional ownership: Investors can buy partial stakes in high-value assets.
- Enhanced liquidity: Tokens trade on secondary markets, unlocking capital in illiquid assets.
- Automated compliance: Programmable rules enforce regulatory requirements.
Example: Tokenized diamonds tracked via blockchain ensure authenticity from mine to retail
What are Cryptocurrencies?
Cryptocurrencies are digital or virtual currencies that use cryptography for security. They operate on decentralized networks based on blockchain technology, functioning independently of central banks and governments. .
Business Applications of Cryptocurrencies
Digital currencies like Bitcoin and Ethereum leverage blockchain for secure peer-to-peer transactions. Benefits for businesses include:
- Lower fees: Reduced processing costs compared to credit card.
- Global reach: Borderless transactions attract international customers.
- Faster settlements: 24/7 operations eliminate traditional banking delays
