Which statement describes Centralized VCs?

• A. They have no repositories and several administrators
• B. They have a centralized repository and a single administrator (e.g. Liberty Reserve)
• C. They operate as fully decentralized systems with no intermediary
• D. They require government backing for all exchanges

Answer: (B)

Centralized virtual currencies are run by a single organization that maintains a central ledger or repository of all accounts and transactions. The administrator controls issuing the currency, validating transfers, and can authorize, reverse, or freeze transactions as needed. This setup concentrates control and accountability in one entity, which is why an example like Liberty Reserve is often cited: it operated with one central database and one controlling administrator rather than a distributed network. In contrast, systems with no central repository or multiple administrators spread control across many parties, making them less centralized. Fully decentralized networks have no single administrator or central ledger. The idea of government backing for all exchanges isn’t what defines centralization, since a central entity can still operate under regulatory oversight or with varying levels of government involvement. So the statement describing a centralized VC as having a centralized repository and a single administrator best captures the essence of centralization.
