Which of the following is a characteristic of a decentralized blockchain?

A decentralized blockchain is characterized by the distribution of control across multiple nodes rather than being managed by a single entity. This decentralization means that no single participant has authority over the entire network, which enhances resilience and security against failures or attacks. Every participant, or node, on the network typically holds a copy of the blockchain, ensuring that no single point of failure exists. This structure supports transparency and increases trust among users, as each can independently verify transactions without relying on a central authority.

In contrast, centralized systems, which often exhibit characteristics such as single entity management or restricted access protocols, do not provide the same level of trust and transparency inherent in decentralized systems. Thus, the essence of a decentralized blockchain lies in its ability to distribute control and ensure that decision-making power is shared among all participants.
