Every cryptocurrency network has an inseparable dependence on its miners. In the following, you can see the graphs of miners' behavior from the beginning of the Ethereum network until today on a monthly basis.

Conclusion

As seen in the general graphs, the amount of mining was increasing almost monthly. With a closer look in September 2022, it was observed that the number of transactions as well as the number of unique miners has jumped since the morning of September 15, 2022. This is quite possible on the hourly chart. So it can be said that mining has not only not decreased, but has also grown with a new pattern.

On the other hand, we checked the top 10 miners separately. Of course, as it is evident and it is necessary to try, no information was recorded for these miners after 6 am on September 15, 2022. A few possibilities that come to my mind. First, these miners have stopped their activity or are mining with a new address. Of course, this procedure change takes some time to update itself.

The Merge

• Ethereum Mainnet uses proof-of-stake, but this wasn't always the case.
• The upgrade from the original proof-of-work mechanism to proof-of-stake was called The Merge.
• The Merge refers to the original Ethereum Mainnet merging with a separate proof-of-stake blockchain called the Beacon Chain, now existing as one chain.
• The Merge reduced Ethereum's energy consumption by ~99.95%.

==The Merge was executed on September 15, 2022==. This completed Ethereum's transition to proof-of-stake consensus, officially deprecating proof-of-work and reducing energy consumption by ~99.95%.

Now, for a more detailed analysis, we will look at the hourly changes in September 2022. The breakdown of the chart on September 15 is clearly visible.

For additional review, we evaluate the behavior of the top 10 miners individually in September 2022.
