The Bitcoin mining difficulty has increased once again. A 2.3 percent increase from the previous existing difficulty levels was reported on September 12, 2016, making it the fourth raise (fifth correction) since the Bitcoin mining rewards halving in early July 2016.
At present, the difficulty level stands at 225,832,872,179 compared to the earlier level of 220,755,908,330. Similarly, the total hash rate of the Bitcoin network has also increased from 1,580,232,334 GH/s to 1,616,574,667 GH/s during the same time interval.
Bitcoin Mining Difficulty and Block Generation Times
The difficulty level correction is an inbuilt function in the Bitcoin software to ensure constant block generation times. The Bitcoin network ideally discovers/generates one new block every 10 minutes. The block generation time has a direct correlation with the difficulty levels and network hash rate. The use of latest mining hardware known for greater efficiencies increases the total hash rate of the Bitcoin network. This, in turn, will significantly reduce the average time taken to discover new blocks. In such cases, the Bitcoin network starts to take corrective measures by increasing the difficulty
