Unit assessment

Answer every question, then review the reasoning. Complete at least 80% correctly and every safety-critical question correctly. Reference links open a new tab so this attempt stays here. Answers and results are only shown for this attempt; nothing is saved.

1. Which statement correctly separates mining from checking the rules?

A fast enough miner can approve any transaction.Miners propose blocks; nodes check the rules.Nodes replace the need for proof of work.

2. Why does using electricity not prove that a miner is doing useful work?

It must also get new work and send back valid results.A powered miner always earns a fixed reward.Pool communications only matter during installation.

3. A dashboard reports 100 TH/s. What does it measure?

One hundred trillion transactions per second.One hundred trillion hashes per second.One hundred blocks per hour.

4. What changes when the proof-of-work target becomes lower?

Every hash takes longer to calculate.More results qualify.Fewer results qualify.

5. A pool accepted a share. What does that tell you?

The miner definitely found a Bitcoin block.The submission met the pool’s acceptance rules.The machine’s electrical installation is correct.

6. Two miners sent different numbers of shares. What else do you need to compare their work fairly?

Nothing else; the raw share counts are enough.Only each machine’s highest hashrate reading.The share difficulty and the time period.

7. Several miners on the same switch drop off the dashboard at the same time. What is a sensible first idea to check?

Each hashboard failed on its own at that exact moment.The shared network path may be involved.Failing at the same time rules out a shared problem.

8. What does a management dashboard prove by itself?

Only what its readings showed when collected.That every power connection is safe.That all displayed miners are earning the same revenue.
