Based on the current currency price in 70 yuan (the data source is not trumpet), it is estimated that the cost of a single miner is 40,000 yuan, and 80T storage space needs to be dug up to recover 572 tokens. Therefore, the payback period of a single miner is as follows (calculated from the official excavation):

Back to the original periodic calculus table

Example of calculation method:

1 month: 572 tokens need to be mined in 1 month, and the total output of Filecoin is 134 13 193, so the storage computing power is required to account for 572/ 134653 of the whole network. And so on.

The formula for storing computing power has not been published. According to the official white paper, it is related to data storage, replication, distribution and retrieval. In this paper, the ideal model is used for calculation. Considering only the storage capacity, the total storage capacity of the whole network must be lower than 1877847TB (approximately equal to 1.9EB).

Therefore, the Interstellar Ao Yun hard disk mining machine can retrieve this cycle by reverse calculation under the ideal condition of only considering the storage capacity. Based on the current currency price in 70 yuan (data source is not trumpet), the cost of a single mining machine is 27,000 yuan, with 80T storage space. If the total storage capacity of the whole network is insufficient 1.9 EB in the first month of Filecoin's excavation (the annual shipment of HDD in 2017 is about 640EB, so the initial online capacity of IPFS exceeds the possible performance of1.9 EB).
