Terahash in mining

4 weeks ago 0 22

The chances of winning the race to earn digital currencies are determined by the processing power of the equipment. For this parameter, the cryptocommunity uses special designations. Terahash is a unit of measurement that shows how much time is required for one device to check transactions in a block. The factor is fundamental in determining profit.

What is terahash

Mining digital currencies requires powerful hardware. Its performance is measured in H/s. Terakesh is a trillion of such calculations. The higher the TH/s, the more combinations the device generates in a given period of time. Some miners increase their overall hash rate by pooling together. They then divide the rewards according to the TH contribution.

What the parameter is for

The processing power of an ASIC is measured in TH/s. This is the main characteristic when considering buying a device and calculating profits. In October 2022, popular models of asics calculate 110-200 TH/s, which far exceeds the values of video cards.

Miners are constantly competing for the first place. It is important to assess your chances by first recognizing the performance of the technique.

The indicator also represents the computing power of the network. For example, in October 2022, the RVN hashing speed is 15.70 TH/s.

In what units is TH measured

The indicator is equivalent to 1 trillion hashes per second. In addition to this parameter, the hardware has an efficiency value, which is measured in joules (J/TH) or watts (W/TH) per terahash.

What affects the level of terahesh

When buying an ASIC, the first thing to look at is the TH/s figure. The following factors affect its level:

The number of devices. The more asics, the more efficient the mining.
Temperature. The speed of operation decreases if the equipment is subject to overheating.
Timings. This is the time it takes for the device to execute a command. The asic is re-flashed to adjust the indicator to maximize efficiency.

Increase the level of TH with the help of overclocking. For example, the Antminer S19 Pro asiq has a default hash rate of 110 TH/s. It can be increased to 150-180 TH/s by connecting 6kW or 8kW power supplies. Antminer S19 can be overclocked from 95 TH/s to 125 TH/s by changing the cooling method.

How to know the TH level

To determine the TH level, you can look up the specifications on the manufacturer’s page or download the mining software and run a test on the hardware. Another way is to use special calculators. Minerstat helps you find out the value of the parameter and calculate the profitability of the device.

Optimal TH in mining

The hashes created are random and cannot be predicted. It takes many attempts before a block is added to the network. The TH/s value in mining affects the speed of transaction processing.

In October 2022, bitcoin hash rate is 295 EH/s. This means that 295 quintillion equations are created per second. To find out the probability of finding a block, you need to divide your own hash rate by the total hash rate.

If you put together a farm of 2 Antminer S19 Pro + Hyd asics with a combined value of 396 TH/s, they will generate 396 trillion combinations per second.

Such a setup will allow you to earn 0.00015282 BTC or 183 rubles of net profit per day. The chances of finding the block on your own are very low. It is 0.000001%. Therefore, miners create farms with dozens of devices or join pools. However, you need to take into account that large assemblies consume a lot of electricity. The table shows the characteristics of popular models of Bitmain Antminer.

Model	TH/s	Power (W)	Electricity price per day (₽)
KA3	166	3154	~ 467
T19 Hydro	158	5451	~ 807
T19 Hydro	145	5438	~ 805
S19 XP	140	3010	~ 445

Hashrate in cryptocurrency

Each token has an indicator of the total processing power used to verify transactions on the network. Based on this metric, miners decide whether it is worth their efforts in mining cryptocurrency. Also, this metric is important for security assessment.

The higher the value, the more difficult it is for an attacker to launch an attack on the blockchain. If a token’s hash rate drops rapidly, crypto platforms may restrict trading or delist it.
