Centralization refers to an organizational structure where power, decision-making, and control are concentrated in a single entity or central point. In the cryptocurrency and blockchain domain, centralized systems are controlled by central authoritative bodies such as banks, governments, or specific organizations that have ultimate authority over system operations, rule-making, and transaction validation, standing in direct contrast to decentralization.

Immutability is a fundamental property of blockchain technology where data, once recorded on the blockchain, cannot be altered or deleted. Implemented through cryptographic hash functions and distributed consensus mechanisms, this characteristic ensures data integrity and trustworthiness across the network. Immutability can be categorized as physical (tamper-resistance at the technical level) or logical (constraints at the consensus rule level).
