How Does the Time-to-Block-Discovery Relate to the Network’s Difficulty Target?
The network's difficulty target is specifically designed to ensure that the average time to discover a new block remains constant (e.g. 10 minutes for Bitcoin), regardless of the total hash rate.
If the time-to-block discovery deviates significantly from the target, the network's difficulty adjustment mechanism will automatically correct the difficulty to bring the average time back to the target.
