Keep Bitcoin Blocks on Time

Bitcoin aims for a new block about every 10 minutes. When miners join or leave, the network adjusts difficulty every 2016 blocks (an epoch). In this game, you are the regulator: slide difficulty up or down and survive three epochs.

Watch Last Block time. Red means too fast (lower difficulty). Blue means too slow (raise difficulty). Green and gold mean you are on target. If the congestion meter fills up, the mempool overflows and you lose.

Difficulty Tycoon

Miners join and leave the network. Adjust the difficulty slider to keep block times near 10 minutes. Survive 3 epochs without maxing out congestion.

Target: keep last block near 10:00 100%
Fast blocks (lower difficulty) Slow blocks (raise difficulty)
How to play: If the last block is red (under 8m), lower difficulty. If it is blue (over 12m), raise difficulty. Keep it green near 10m for combo points. Watch for hashrate events and react before congestion maxes out.

What this game teaches

  • Difficulty adjustment keeps Bitcoin block times steady even when mining power changes.
  • Every 2016 blocks (about two weeks) the network retargets difficulty automatically.
  • More hashrate without a difficulty rise means faster blocks; less hashrate means slower blocks.
  • Slow blocks can congest the mempool, the waiting room for unconfirmed transactions.
  • The 10-minute target is why Bitcoin stays predictable for the whole world.
