II. Understanding Blockchain Technology
A. Core Principles of Blockchain
Blockchain operates on a decentralized and distributed ledger system. It consists of a chain of blocks, each containing a record of transactions. These transactions are securely linked and timestamped, creating a transparent and tamper-resistant ledger.
B. How Blockchain Ensures Security and Transparency
Blockchain’s security is rooted in its cryptographic algorithms and consensus mechanisms. Once data is recorded on the blockchain, it becomes extremely difficult to alter, ensuring data integrity. Additionally, transparency is maintained as all participants have access to the same version of the ledger.
C. Comparison with Traditional Centralized Systems
Compared to traditional centralized systems, blockchain offers greater security, transparency, and control. While centralized systems are susceptible to single points of failure and unauthorized access, blockchain’s decentralized nature mitigates these risks.
