1.3 Importance and Applications

Importance of Blockchain

• Enhanced Security: Blockchain’s unique way of recording information makes it secure and tamper-resistant. The cryptographic linking of blocks and the decentralized nature of the network make it extremely difficult for data to be altered without detection.
• Transparency and Trust: Every transaction on the Blockchain is visible to all participants, fostering transparency. This transparency builds trust among users, as every action is traceable and irreversible.
• Decentralization: By not relying on a central authority, Blockchain democratizes data and reduces the risk of centralized control and failure.
• Efficiency and Speed: Blockchain can streamline and speed up processes, reducing the need for intermediaries and removing bottlenecks typical in traditional systems.
