If millions of new mining machines join the network, wouldn’t blocks be found much faster than 10 minutes?
Bitcoin prevents this with the Difficulty Adjustment mechanism.
⏱️ Automatic Calibration
Every 2,016 blocks (~2 weeks), the protocol compares the actual time taken against the target time of 20,160 minutes (14 days).
- If blocks were mined in 10 days (hashrate increased), difficulty increases by ~40%.
- If blocks took 18 days (hashrate decreased), difficulty drops accordingly.
This keeps block generation steady at ~10 minutes regardless of global hardware growth.
🧠 Today's Key Takeaway
- Difficulty adjusts every 2,016 blocks to maintain a 10-minute average block interval.
- Ensures supply inflation remains strictly controlled despite hardware changes.
