Blockchain Beyond Cryptocurrency: Innovative Applications in Supply Chain and Finance

1: Introduction to Blockchain Technology

Blockchain technology is a distributed ledger system that records transactions across a network of computers in a secure and transparent manner. Each transaction is grouped into a "block," which is then linked to the previous block, forming a "chain." This decentralized approach ensures that no single entity controls the entire ledger, enhancing security and trust.

Key features of blockchain technology include:

• Decentralization: Unlike traditional databases controlled by a single entity, blockchain operates on a network of nodes, distributing control and minimizing the risk of centralized failures.
• Transparency: Every participant in the blockchain network has access to the ledger, ensuring that transactions are visible and verifiable.
• Immutability: The blockchain records data permanently and tamper-proof, preventing any alterations or deletions.

These characteristics make blockchain a powerful tool for various applications beyond cryptocurrencies.
