Question #298 ·
How do changes in mining difficulty and hash rate reflect the Bitcoin network’s health and security?
- They count active addresses and transactions, estimating network usage but not directly indicating mining security levels.
- They measure Bitcoin supply and adjust rewards, controlling how many coins miners can generate per year.
- They show computing power and participation levels, indicating mining profitability, network security strength, and attack resistance. Right answer
Why is this the correct answer?
This is correct because mining difficulty adjusts to maintain a 10-minute block time as hash rate changes. A rising hash rate and higher difficulty mean more computing power securing the network, making it harder and more expensive to attack. When difficulty falls, it can signal miner exits under stress. Beginners should know that mining network measured in hashes per second">hash rate and difficulty are key on-chain indicators of network health and security.
