This article was originally written by IPFS Force Zone In "Iceberg Model: Unveiling the Secrets Behind the Stability and Output of The Force Mining Pool" and "Iceberg Model 2: Why The Node Block Efficiency and Single T Revenue of The Force Operation and Maintenance Are So Outstanding", we introduce how to improve the utilization rate of mining equipment resources and the necessary conditions for obtaining stable mining income. Figure 1, Filecoin Iceberg Model, IPFS Force Zone If the above two points are achieved, the computing power will be steadily and economically grown, and the mining income will be maximized. However, Filecoin's mission is to create a decentralized, efficient and powerful infrastructure for human information, with huge commercial applications and landing expectations. In order to ensure that miners can provide high-quality data storage services, Filecoin uses a penalty mechanism to restrict miners' slacking behavior. Penalty Mechanism and WindowPoSt Although Filecoin officials have adjusted the relevant parameters in “Creating the Filecoin Economy”, the setting of the penalty mechanism is still very strict: If a miner discovers a sector failure and proactively reports it, the expected 2.14-day revenue of the sector will be deducted; If the miner fails to detect a sector failure but the system discovers it during the WindowPoSt period, the miner will be penalized 3.5 days of the faulty sector's revenue as a sector error detection fee; If a sector is terminated before its expiration, part of the block rewards obtained by the sector in the previous period will be deducted (≤140 days, half of the income of the service time will be confiscated; >140 days, 70 days of income will be confiscated).
WindowPoSt in Filecoin's replication proof is the sword of Damocles hanging over the heads of miners. Its function is to verify whether the miner's node continues to store the corresponding data as required. The cycle of WindowPoSt is one day, which is divided into 48 windows (Window), each window is 30 minutes. The more sectors and the larger the volume of miners, the higher the number and difficulty of challenges. Miners must complete the data verification challenge within the specified time. Any failure will result in punishment and loss of computing power. The situation of network-wide computing power loss Figure 2. Miner A’s total hashrate curve, filscan.io Figure 3. Miner B’s total hashrate curve, filscan.io Figure 4 , Miner C’s total computing power curve filscan.io Figures 2, 3, and 4 show three selected mining nodes that participated in the space race and ranked high. From the charts, we can see that all three mining nodes have experienced a loss of computing power, most likely because they were punished. There are many reasons why miners fail to complete WindowPoSt within the specified time, such as network transmission problems, disk damage, and software bugs. Especially the problem of disk damage, even if the damage rate is very small, it is inevitable that a certain amount of hardware equipment will be damaged due to the volume. How to deal with the above problems is a great challenge to the operation and maintenance capabilities of miners. Nodes of the Force Mining Pool Figure 5, t02438 total hashrate curve, filscan.io Figure 5 shows the computing power growth curve of the Force operation and maintenance node t02438. Since the launch of the space race, its computing power has maintained a relatively stable growth. In order to ensure that the computing power is not penalized, the engineers of the Force Zone have made considerable efforts. This includes the monitoring system, which monitors the stability of network transmission and the status of hardware equipment in real time; redundant backup to deal with disk failures and ensure that data will not be lost; software algorithm optimization to shorten the WindowPoSt time. Can the above ensure that the computing power will not be punished and the revenue will not be lost? Of course it is not that simple. Even the world's leading Internet companies such as Alibaba, Tencent, and Amazon dare not guarantee 100% system stability. For this reason, the Force Operation and Maintenance has built a series of risk control mechanisms and formulated plans for various emergencies. Even if an emergency event with a very small probability occurs, the loss can be reduced to a minimum. Filecoin miners are under greater pressure. On the one hand, the operation and maintenance of Filecoin miners is more difficult than traditional operation and maintenance; on the other hand, if an abnormality occurs and WindowPoSt is not completed on time, the assets will be lost. In order to maximize the single T income, block efficiency and overall FIL income, the Force Mining Pool is building a castle like a copper wall and iron wall in the place you can't see "under the water", concentrating all risks in a "thermal gate" with only narrow passages. The operation and maintenance team of the Force Mining Pool has transformed into brave Spartan warriors. Each person guards a direction with the support of his comrades behind him, guarding the stability of the node 24 hours a day, 7 days a week.
