This article was originally written by IPFS Force Zone If you torture the data, it will tell you everything. Interpreting the data well is often more important than what data you want. Previously, a brief logical calculation of the key mining indicator "luck value" was made in the article "Force nodes continued to have high returns in the first half of the space race, and mining efficiency reached 138%". The article mentioned the direct correlation between "luck value" and "single T income", and explained why single T income is the core reference indicator of miners' benefits. This article briefly discusses and analyzes single T income. How to calculate the revenue per TiB Basic Definition The single T revenue of the Filecoin network refers to the computing power invested by the entire network in a given period to generate a certain amount of new FIL. After taking the average value, the new FIL generated by each T of computing power in the period is obtained. This definition applies to the calculation of single-T revenue for the entire network and the calculation of single-T revenue for miner nodes. The "average value" method is not unique, which is why the values presented by multiple Filecoin block browsers are not the same. Theoretical formula We shorten the cycle. When the mining cycle is a block height, the single T income is the value of the new income at that height divided by the computing power invested at that time. This value only represents one height, but since the denominator of the division value is set to 1TiB, we only need to weight the numerator to lengthen the cycle. This formula is in block height. If you need to use time as the unit, you can simply convert it. According to the current Filecoin network's stable block generation of 30 seconds, a natural day's block is 2880 units, n-t+1 is 2880, which is the single T income in the past 24 hours, and n-t+1 is 20160, which is the single T income in the past week. This logic is more accurate than taking the median of the division value, the average of the division value, etc. The specific formula is as follows (the formula may be different for different expressions):
Figure 1 shows the performance of single T revenue within 24 hours of the network when the block height is 70233, which is 0.49FIL/TiB, that is, the revenue generated by 1T computing power in the cycle of block height 67354 - 70233 (one height is 30s).
Figure 1, filecoin network chain data, filscan.io Figure 2 shows the performance of single T revenue of node t02438 within 24 hours. You can also view the single T revenue performance within 30 days.
Figure 2, t02438 mining data, filscan.io The above is a simple presentation of the historical data of network operation during SpaceRace, but based on the modeling and deduction of historical data, we can peek into the simple trend of future single T revenue in the context of similar current network status.
Single T profit rules ( based on the perspective of the entire network)
FIL release rules
Combined with the economic model parameters used in the first round of SpaceRace, with an initial baseline of 1EB for the total network computing power and a 200% annual growth rate, the network grows by an average of 10PiB per day. According to the token release rules deduced in the Force Research series (i.e., the FIL released by the network at each height), the amount of FIL released at the tth height = simple supply + baseline supply (before the baseline is met) =
+ When the network reaches the computing power baseline requirement, token release will return to linear release as a whole, that is, using only the logic of simple supply; before reaching the baseline, only 30% of the tokens use simple supply, so after reaching the baseline, the linear release formula is the simple supply part mentioned above/30%. Computing power growth law Based on the regression deduction of the historical data trend of the computing power of the entire network in the first round of SpaceRace, by comparing exponential regression, logarithmic regression, power regression, and linear regression, it can be concluded that the linear regression model has a fitting degree of up to 99.23%, that is, the accuracy of deducing the future computing power growth trend through this regression line is high enough without more interference factors. Figure 3, Network computing power data, filscan.io Select the linear regression formula: y = 3.7967t - 6985.4 (R² = 99.23%), where t is the block height, y is the computing power, and t and y are natural numbers greater than 0. Single T revenue estimate Here we can get the formula for the network's computing power on a certain day: 3.7967t - 6985.4; the formula for the daily release of new FIL (with the background of the network growing by 10PiB per day): Bring in the single T profit formula at the beginning: By weighting, we can get the single T profit performance of the entire network in the height range from t to n. Single T income & height example When the data deduction requirement is adjusted to the single T revenue of the entire network that changes with the growth of height (that is, the cycle to be calculated is only one height), the formula is fine-tuned to: In this way, the deduction results are shown in Figure 4. We can see that with the uniform increase in network computing power, combined with the FIL release model, the single T income of the entire network drops rapidly in the early stage, and tends to stabilize at an average of 0.0001-0.0002 per T per height before triggering the baseline.

The single T revenue in this article mainly includes actual and theoretical situations. The actual situation is to reflect the actual single T revenue in a timely manner according to the network situation; the theoretical situation is the content of this article, which is assumed by the proposed revenue and network growth situation. However, because the actual situation of each miner is different, the single T revenue will also be different, so the above argument regards all as the ideal situation with the same operation and maintenance level, which is only for reference.
