1. Renren mine's IPFs computing power has been connected to Athena mine, and its performance is still very high. The platform also makes in-depth algorithm and code level optimization for filecoin's seal speed, space-time proof speed, and I / O reading and writing speed of Pb level data, and has instry-leading advantages in terms of computing power improvement and block rate. OK, if you need, please feel free to ask.
2. The essence of mining machine is different
the essence of BTC / eth mining machine is data computing equipment
mining has developed from the initial personal computer mining, video card mining and personal mining machine mining at home to the cluster and professional large-scale mining. No matter from the initial CPU mining, GPU mining, or later FPGA mining, ASIC mining, large-scale cluster mining, its essence is to focus on improving the data computing capacity of mining equipment. The main internal parts of the mining machine are the power calculation board or graphics card, and the large cooling fan
the essence of IPFs miner is data storage device
the different essence of miner makes the configuration characteristics of storage miner very different from BTC / eth miner. The storage miner mainly used for data storage does not need too much computing power, that is, the performance of CPU is not required to be too high, and the memory capacity is suitable, but it needs a large capacity of storage space. That is to say, the density of hard disk per unit space should be large, and as many hard disks as possible should be equipped. At the same time, the I / O performance of data storage should be high, and the bandwidth channel should be as high as possible. Because of the special requirements of data storage, mining machine must be stable, safe and not easy to damage
filecoin officially announced that GPU is needed for mining. Although it means that computing power resources are also needed, the miners who use GPU get rewards for mining blocks. Most of them don't participate in mining blocks and only provide storage devices. They don't need GPU and can mine as long as they have a hard disk

3.
The calculation of bearing capacity is more complex, and the general application will not use the calculation method to determine the bearing capacity
According to the failure mode of O-ring, the failure caused by pressure is usually caused by the O-ring being squeezed into the gap, so the fit gap is one of the important external factors affecting the bearing pressure; It can also be seen that the hardness of the sealing ring itself is also an important factor Therefore, the bearing capacity data of general manufacturers is a curve related to clearance and hardness, and users can design their own structure and fitting accuracy according to this curve It can be seen from the figure that the smaller the fit gap is, the higher the bearing pressure is, the higher the hardness of O-ring is, and the higher the bearing pressure isif the pressure is high, it is recommended to install a retaining ring
4. Compared with the cross-section diameter of O-ring, the material with shore hardness above 50 can achieve good sealing effect by compressing more than 25%. It is not necessary to calculate the reaction force of O-ring without considering the stress effect on the machine part.
5. As a decentralized storage network of computing power market, the mining market derived from filecion has been very responsive since its implementation. Looking at the whole filecion mining market, we have a vague knowledge about the mining of filecion. Today, let's analyze the encapsulation efficiency of filecion. "Encapsulation efficiency" is a very important investment point for the mining of filecion, Understanding it is very important for the whole mining process< At present, the reward of filecoin is divided into storage market, retrieval market and block reward. The most important thing in mining is reward. Storage capacity is the engine of filecion's current blockchain network. Nodes allocate hard disk space to filecion network through the process of "sealing" to obtain storage capacity. Sealing divides storage space into multiple business areas to store data. The more storage sectors nodes add to the network, the more client data they store, The more eligible for the fil award
unlike the traditional workload proof of blockchain, which requires nodes to perform compute intensive but useless tasks to win block rewards, filecoin nodes obtain block rewards by proving that they provide reliable and useful storage for network clients
anyone can contribute storage resources to the network and start getting rewards immediately. In addition, it greatly encourages nodes to store useful data, because encryption economics greatly subsidizes the storage of actual customers on the filecoin network. This motivates legitimate use cases and highlights the core mission of filecoin to store the most important human information. So, for example, data sets that help us study the universe or cure diseases can be given more weight on the Internet
02, filecoin mining
filecoin mining can be simply divided into two steps: worker and miner
worker is responsible for calculation. The original data is mathematically calculated by SDR algorithm, and then the calculated data is encapsulated into the sector of the hard disk, and submitted to the chain to generate replication proof. The miner obtains the computing power, and this process consumes a lot of CPU, memory and GPU resources. Then, the filecoin network allocates the right of block packing (that is, the voting right of block packing) according to the computing power held by the miners. The greater the computing power, the higher the winning rate. When the miners participate in the block packing, they need to submit the space-time proof repeatedly, and the node that has completed the space-time proof can get the reward of block packing.

6. For example; A square cone-shaped container [for example, its volume is 1 cubic decimeter], is filled with ordinary air through an air pump. The more 50pA, the more pressure in the container will increase. Is there any formula? These numbers are just for the convenience of prawns. If you have other needs, you can make your own assumption,
