Cold Knowledge | Understanding the “Hash Rate Curve”

The hashrate curves of all the major mining pools seem to be roughly the same, but during the evaluation process, Tiao Sir discovered that there is a mystery. Points on the same curve actually have different meanings, which will cause errors when miners calculate the actual profit rate!

In order to think about what miners think and solve their problems, Tiao Sir will introduce the functions and specific usage scenarios of different mining pools' computing power curves in detail.

In this issue, SIr will use the top four mining pools in Bitcoin computing power as an example to explain the computing power curve.

The similarities between the hashrate curves of various mining pools are as follows:

• The horizontal axis is time, and the vertical axis is computing power/rejection rate.

• There are two curve modes: "1 day" and "1 hour".

• In the "1 day" curve mode, you can view computing power data for up to 30 days.

• In the "1 hour" curve mode, you can view the hashrate data for up to 24 hours.

Remark:

1. F2Pool is divided into "30 minutes" and "1 day" curve modes.

2. BTC.com and Poolin mining pools additionally provide rejection rate curves.

Sir can't help but ask, for those mining pools that do not provide rejection rate curves, where can we see the rejection rate of a certain day? After all, the rejection rate may also be a problem with the task issuance of the mining pool!

The hashrate curve function allows miners to intuitively view hashrate changes, and all miners will use this function. However, not all miners know how to obtain the data of the points on the hashrate curve.

When I selected Sir to conduct mining pool evaluation and statistical data, I found that the data collection methods on the computing power curves of various mining pools were actually different!

BTC.com

• The computing power curve is a real-time updated curve. The computing power curve is updated in real time according to the current computing power.
  

• The rightmost point of the “1 day” mode curve is the average computing power from 8:00 AM on the horizontal axis to the current time.

• Except for the rightmost point, all other points of the "1-day" mode curve are the average computing power from 8:00AM on the horizontal axis date to 8:00AM on the next day.

• The rightmost point of the “1 hour” mode curve is the real-time computing power.

• The points of the “1 hour” mode curve except the rightmost point are the average computing power for one hour on the horizontal axis.

AntPool

• The computing power curve is a curve that is updated regularly. The points on the computing power curve can only represent the average computing power of one day or one hour.

• The point on the "1 day" mode curve is the average computing power from 8:00 AM on the previous day to 8:00 AM on the current day.

• The point on the “1 hour” mode curve is the average computing power in the previous hour on the horizontal axis.

F2Pool

• The computing power curve is a curve that is updated regularly. The points on the computing power curve can only represent the average computing power of one day or one hour.

• All points on the "1-day" mode curve are the average computing power from 8:00 AM on the previous day to 8:00 AM on the current day.

• All points on the “30-minute” mode curve are the average hashrate for the last 30 minutes on the horizontal axis.

Poolin

• The computing power curve is a real-time updated curve. The computing power curve is updated in real time according to the current computing power.

• The rightmost point of the “1 day” mode curve is the average computing power in the previous three hours.

• Except for the rightmost point, all other points of the "1-day" mode curve are the average computing power from 8:00AM on the horizontal axis date to 8:00AM on the next day.

• The rightmost point of the “1 hour” mode curve is the real-time computing power.

• The points of the “1 hour” mode curve except the rightmost point are the average computing power for one hour on the horizontal axis.
  

1. View the current real-time mining pool computing power

The computing power curve that supports real-time updates (such as BTC.com, Poolin) can view the real-time computing power fluctuations, while the computing power curve that is updated regularly (such as F2Pool, AntPool) can only show the average computing power within a certain period of time.

2. Check the mining pool computing power on a certain day in the past

For hashrate curves that support real-time updates (such as BTC.com, Poolin), you can check the point on the horizontal axis that is the target date. For hashrate curves that are updated regularly (such as F2Pool, AntPool), you need to check the point on the horizontal axis that is one day after the target date.

3. Check the rejection rate

The smaller the default maximum coordinate, the more fluctuations in the rejection rate and the better the warning effect.

In general, there are two types of curves:

1. Mining Date Category (BTC.com/Poolin)

   The horizontal axis of the daily curve is the marked date 8:00 AM to   Average computing power at 8:00AM the next day .

2. Settlement Date Class (Antpool / F2Pool)

   The horizontal axis of the daily curve is 8:00 AM on the day before the marked date.   to   Date 8:00AM   Average computing power.

Each mining pool should consider adding a rejection rate curve. Historical data is still very important!

After writing this article, I lost half a pound of hair. They all have curves, but why are they so prominent? To be a miner, you need not only money, but also good eyesight and intelligence!
