14ghs computing power
1: the price of the miner is higher
2: we need to consider how long it will take to get back the original
3: it's troublesome to buy and troublesome to maintain
4: it is time-consuming and power consuming, and it also needs to run the mining software with the computer on
5: there are risks of depreciation and damage
the above risks and defects make many miners shy away from buying mining machines. Fortunately, we are in the era of cloud computing. Now the era of "cloud
miner" has finally come. Now there are websites selling computing power on the Internet. That is to say, they have a large number of mining machine cluster equipment and sell their computing power on the Internet, Generally speaking, cloud mining machine mining has the following advantages:
1: there is no saying that "you can't get back the cost". How much you dig is how much you earn. If you don't want to dig, you can sell GHS computing power at any time
2: there is professional mining equipment space to ensure the uninterrupted operation of mining machinery
3: no freight, no electricity, no depreciation, no risk of damage
4: computing power can be bought and sold at will, not limited to 1g, or only 0.001g. If you want to buy more, you can buy more, and you can sell if you don't want to
5: "cloud miner" digs bitcoin on the server side. You don't need to turn on the computer, just wait to receive bitcoin
now there are fewer and fewer bitcoins that can be g, and it is more and more difficult. If you want to dig bitcoin, you have to start early
although you don't have a graphics card worth thousands of yuan and a miner worth tens of thousands of yuan, you can be a hardworking bitcoin miner because of the cloud miner! Get a lot of money. Now I will take you to operate the happy process of mining with the cloud mining machine, because at present, the interface of the cloud mining machine is mostly in English, which is difficult for some beginners to understand. I will explain each detail carefully with pictures and text, and translate it into Chinese, please rest assured.

as a blockchain, filecoin also needs block procers. Since there are block survivors, block rewards should be given to block procers
how much is the first reward
in the first year, the average reward of a single blockchain is about 145, which graally decreases. In the sixth year, the reward of each block is about 81, which is the reason why the reward of filecoin block is halved in six years
so when the blockchain was just launched, there were 145 rewards for a single block, but there were not so many miners, so it was a very good mining opportunity
What does mining rely on
at present, it doesn't seem to rely on much
how to select block procers
select a number from the previous block, and then hash it with the miner's private key signature. If the hash value meets the conditions, the miner will be selected
this process doesn't need to work hard as bitcoin does, because it only needs to be calculated once, so it seems that high computing power or powerful CPU is useless. Because this algorithm seems to have nothing to do with the pledge space of miners, so as long as the miners meet the conditions, they can be rewarded
storage mining and retrieval mining
as the largest filecoin, this is the driving force of miners' long-term mining. The total number of tokens in filecoin is 2 billion, 70% of which is distributed to miners, that is, 1.4 billion tokens
however, the 1.4 billion tokens need to be subtracted from the block reward tokens to generate the benefits of storage mining and retrieval mining
What are the specific benefits? In fact, it is uncertain, because there are two markets to decide, one is the storage market, the other is the retrieval market. Every miner needs to go to the market to quote, store or search users to find and form orders. So, it's a very dynamic process
this is a bit like the decentralized exchange that we use now. There will be orders or sales orders one by one, and the final platform can only get the average transaction price. And everyone's quotation or order transaction price is different
it should be noted that when filecoin was first launched, there were not too many storage users, so most of the miners' income should come from block rewards. Therefore, it is a major play, which is very worthy of investment
I hope I can help you. Shanghai ello technology is specialized in developing filecoin management platform, and has a deep research on filecoin
GHS system includes two aspects: GHS system roughly divides the hazards of chemicals into three categories and 28 items:
1) physical hazards (such as 16 items of flammable liquid and oxidizing solid)
2) health hazards (such as acute toxicity, skin corrosion / irritation, etc.)
3) environmental hazards (such as water and ozone layer). GHS system uses two ways to publicize the hazard information of chemicals:
1) label
2) safety data sheet (SDS)
note: it is often called "material safety data sheet" (MSDS) in Chinese standards
in GHS system, a complete label contains at least five parts: signal word, danger description, pictogram, prevention description, etc
the safety data sheet (SDS) for unified publicity of chemical hazard information includes the following 16 aspects: 1. Identification, 2. Hazard identification, 3. Composition / composition information, 4. First aid measures, 5. Fire protection measures, 6. Accidental leakage measures, 7. Handling and storage, 8. Contact control / personal protection, 9. Physical and chemical properties, 10. Stability and reactivity, 11. Toxicological information, 12. Ecological information, 13. Disposal consideration, 14. Transportation information, 15. Management information, 16. Other information
