Certified Blockchain Solutions Architect (CBSA) — Question 46

Every node needs to keep track of time AND it needs to be in synch with its other peer nodes on the blockchain. In Bitcoin for example the current median for time is around?

Answer options

• A. 7 minutes
• B. 7 seconds
• C. 17 seconds
• D. 70 Minutes
• E. 70 Seconds

Correct answer: D

Explanation

The correct answer is D, as the median time in the Bitcoin network is approximately 70 minutes, which reflects the average time taken for blocks to be mined. The other options are incorrect as they do not accurately represent the average block time seen in Bitcoin, which is significantly longer than both 7 seconds and 17 seconds.
