Expected return of hpool pool
1. Machine: two ant double blade mining machines (rated speed: 180gh / s, rated power consumption: about 360W)
2. Network: ordinary family 8m broadband connection
3. Test time: from 11:00 p.m. on January 27 to 7:00 a.m. on January 28, 2014, a total of 8 hours
4 Comparison:
a miner in btcguild (EU stratum. Btcguild com:3333
the average speed of 8 hours is 175.92gh/s, and the profit is 0.01424974
one miner operates in f2pool (stratum)+ tcp://stratum.f2pool.com : 3333)
8 hours average speed 180gh / s, revenue 0.01230566
5 The test results are expected (the theoretical value under the difficulty of the day does not consider other factors):
the profit of an ant double blade miner in btcguild mine is 0.00194408 more than that in f2pool mine in 8 hours, 0.00024301 more per hour, 0.00583224 more in 1 day (24 hours), and 0.1749672 more in each month (30 days)
how to mine a mine pool
the location of a mine pool is also very particular. It's not that a mine pool can be built anywhere, but it needs early-stage capital investment. A mine pool is to combine a single mining machine together. Because of the collection of many miners' computing power, the computing power of the mine pool accounts for a large proportion, and the probability of digging bitcoin is higher. The mine pool will distribute rewards according to the contribution value of each equipment
there are many mines all over the world, and the scale of each mine varies from big to small. Generally, small mines no longer have great advantages. Large mines have many miners for mining. For each miner, he can join any mine or join multiple mines at the same time, The first task of the mine pool is to distribute the income to the miners
(1) PPLNs method
this method gathers the shares g by all miners together. Whenever a certain amount of shares is accumulated (generally 30 million shares), the mine pool will allocate the profits of the previous stage to the miners according to the proportion of contribution
in this way, the income of miners depends entirely on the time needed to dig 30 million shares in the mine pool. If you are lucky, you can dig them in a short time, then the income of miners will be more, otherwise it will be less. In return, the pool charges a 3% tax
(2) PPS mode
for users, the income of this mode is relatively stable
the profit mainly depends on the miner's mining speed. As long as the mining speed is stable, the corresponding profit can be obtained, and the profit is real-time, that is, the mine pool will pay the profit for the miner while the miner is running
obviously, every time a block is calculated, the mine pool has paid for all the miners. If the block fails in the subsequent confirmation link, all the losses will be paid by the pool operator. Therefore, this method reces the risk of the miners, but transfers the risk to the pool operator
therefore, usually the ore pool can charge a handling fee to make up for the possible losses caused by these risks. In this mode, the tax of the ore pool is 7.5%
the above is about how to mine. The difficulty of mining has greatly increased, but the mining army is expanding. If the basic equipment does not meet the standard, it will be difficult to gain in the mining instry, because the value of the virtual currency may not be equal to the price of an equipment, and many miners are not just digging bitcoin, Instead, we choose other virtual currencies to mine.
POC is the abbreviation of proof of concept, which means to provide evidence for opinions. It is a set of suggested electronic models, which can be used to demonstrate the design of teams and customers, and allow to evaluate and confirm the conceptual design scheme. The evaluation of POC may cause the adjustment of specifications and design
function:
the commitment of design and the opinions recognized by all will be recorded in the design adjustment document for future reference. In this way, POC continues to develop. If you need help completing these tasks, you can find assistance resources at Queensland University
extended data:
evaluation and verification of POC
the process of evaluation and verification is to seek feedback from risk takers through POC and filing design documents. Through POC evaluation, risk takers may put forward requirements for adjusting specifications and design
sometimes, e to design defects or inappropriate places, the design team may have to go back to the drawing board. Customers may decide to stop designing or look for other teams because the design does not pay enough attention to the needs of customers and users, or because of the instability of customer needs
sometimes the change is caused by the customer organization or project decision-maker. Generally, at the end of the evaluation and verification process, the design commitment and the opinions accepted by all will be recorded in the design documents
this is often an important milestone in the life cycle of proct development. After the evaluation and verification, POC can continue to develop
Bhd's economic model
Bhd's consensus algorithm has been upgraded on the basis of POC, which is called cpoc (conditional proof of capacity), that is, conditional proof of capacity. Each miner participating in Bhd's mining needs to pay 1:3 (dynamic mortgage has been started at present), The latest mortgage ratio is 1:2.9), that is, for every 1TB of hard disk space, you need to mortgage three BHDs to get 100% income, otherwise you can only get 30% income
POC, as a trend in the future, has attracted many people's attention. The layout of miners' mines has begun, and the hpool mine has become a hot spot https://www.hpool.com/ Founded in 2017, it was jointly built by celebrity brother worm and Alex in the coin circle. At the same time, Wanxiang, a well-known blockchain company, also invested in hpool mine. This is not only the recognition of hpool, but also the affirmation of POC ecology. Hpool is the most powerful hard disk mine in the world, and also the first old mine in China to devote itself to POC ecology
nowadays, more and more ore pools and exchanges begin to lay out POCS. The whole ecology has been graally improved, waiting for it is only the last point of the instry east wind.
