Wallet safety quiz

4 questions with explanations. Answer every question, then review your results.

1. Do miners alone decide whether a block is valid? Yes, whoever mines a block can override transaction rules. No. Other network participants independently enforce consensus rules. Only the exchange receiving the transaction decides.

2. Does a blockchain entry prove a real-world statement is true? Yes, recording it makes the statement true. Only when the entry has more than six confirmations. No. The quality of the external information remains a separate issue.

3. Should you enter a recovery phrase into a link sent by support? No. Treat that request as an attempt to obtain control of the wallet. Yes, if the profile uses the wallet company’s logo. Yes, when a transfer is taking longer than expected.

4. Does a signature without a network fee have to be harmless? Yes, because no assets move immediately. No. The signed authorization may still grant rights or enable later actions. Yes, if the message comes from a familiar website.
