Joint mining agreement
do you remember what the consensus mechanism of bitcoin is? The consensus mechanism of bitcoin is pow. To put it simply, the more work you do, the higher the amount of computation you pay, the more likely you will be the first to find the correct hash value, and the more likely you will be rewarded with bitcoin
however, there are some defects in the pow of bitcoin, that is, it is too slow to process transactions, and miners need to constantly collide hash values through calculation, which is costly and inefficient. Friends who are interested in blockchain knowledge should see such a saying:
in order to make up for the deficiency of bitcoin, Ethereum has proposed a new consensus mechanism, called POS (this is the abbreviation of English, which means "proof of equity", also translated into "proof of equity")
POS simply means the same as its literal meaning: equity, equity. The more currency you hold, the more equity you have, the higher your equity
Ethereum's POS means that the more money you hold, the longer you hold it, the less difficult it will be to calculate and the easier it will be to mine
in the initial setting of Ethereum, Ethereum hopes to build a relatively stable system by using POW in the early stage, then graally adopt POW + POS, and finally completely transition to POS. So, it's true that the consensus mechanism of Ethereum is POS, but POS is only a plan or goal at the beginning of Ethereum's release. At present, Ethereum has not yet transitioned to POS, and the consensus mechanism adopted by Ethereum is still pow, that is, the pow of bitcoin, but it is slightly different from the pow of bitcoin
the amount of information here is a bit large,
the first information point is that the consensus mechanism currently adopted by Ethereum is also pow, but it is slightly different from the pow of bitcoin. So, what's the difference between the pow of Ethereum and bitcoin: in short, the mining difficulty of Ethereum can be adjusted, but the mining difficulty of bitcoin can't be adjusted. Just like our college entrance examination, because the teaching situation and the number of students in different provinces are not the same, so the college entrance examination is divided into national papers and provincial independent proposition
Ethereum said that I am in favor of the topic by region. Bitcoin said: No, it must be the same volume in the whole country. The difficulty is the same for everyone
the popular explanation is that bitcoin uses computer computing power to do a lot of hash collisions, enumerate various possibilities to find a correct hash value. The Ethereum system has a special formula to calculate the difficulty of each block. If a block is verified faster than the previous block, Ethereum protocol will increase the difficulty of the block. By adjusting the block difficulty, the time needed to verify the block can be adjusted
according to the Ethereum protocol, the dynamic adjustment method of difficulty is to make the time interval of creating new blocks in the whole network 15 seconds, and the network uses 15 seconds to create blockchain. In this way, because the time is too fast, the synchronization of the system is greatly improved, and it is difficult for malicious participants to launch 51% (that is, more than half) of the computing power to modify historical data in such a short time
the second information point is: in the initial setting of Ethereum, we hope to achieve the transition from POW to
POS through phased upgrade
dating back to 2014, at the beginning of Ethereum's launch, the team announced that the launch of the project would be divided into four stages, namely, Froniter, homestead, metropolis and serenity. In the first three stages, the consensus mechanism adopts pow (workload proof mechanism), and in the fourth stage, it switches to POS (equity proof mechanism)
on July 30, 2015, the first phase "frontier" of Ethereum was officially released. This phase is only suitable for developers. Developers can write smart contracts and decentralized application DAPP on Ethereum network, and miners begin to enter Ethereum network to maintain network security and get Ethereum coins. The leading-edge version is similar to the beta version, proving whether the Ethereum network is reliable or not
on March 14, 2016, Ethereum entered the second stage of "homeland". In this stage, Ethereum provides the wallet function, so that ordinary users can easily experience and use Ethereum. There is no obvious technology improvement in other aspects, but it shows that Ethereum network can run smoothly
in September 2017, Ethereum has reached the third stage of "metropolis"“ "Metropolis" is composed of Byzantine and Constantinople. The goal of this stage is to introce the hybrid chain mode of POW and POS, so as to prepare for the smooth transition from POW to POS. This is the latest popular "Ethereum Constantinople upgrade". In the Constantinople upgrade, Ethereum will make some changes to the underlying protocols and algorithms to lay a good foundation for the implementation of POW and
POS
how much reward will Ethereum get for mining? Miners who win the block creation competition will get the following income:
1. Static reward, 5 ethereums
2. The fuel cost in the block, i.e. gas, we talked about in the last issue
3. As a part of the block, it includes the extra reward of "Uncle block". Uncle is uncle of uncle, and each uncle block can get 1 / 32 of the mining reward as a reward, that is, 5 times 1 / 32, which is equal to 0.15625 ethereums. Here, let's briefly explain the concept of "TERT block". The concept of "TERT block" was proposed by Ethereum. Why should we introce the concept of TERT block? This also starts with bitcoin. In the bitcoin protocol, the longest chain is considered absolutely correct. If a block is not part of the longest chain, it is called a "orphan block". An isolated block is a block, which is also legal, but it may be found later, or the network transmission is slower, and it does not become part of the longest chain. In bitcoin, the solitude is meaningless and will be discarded later, and the miners who find the solitude will not receive mining related rewards
however, Ethereum does not think that isolated blocks are worthless, and Ethereum system will give rewards to miners who find isolated blocks. In Ethereum, isolated blocks are called "Uncle blocks", which can contribute to the security of the main chain. Ethereum's ten second block interval is too fast, which will rece the security. By encouraging the use of tertiary blocks, the main chain can obtain more security guarantees (because the isolated block itself is legal). Moreover, paying the tertiary block can also stimulate the miners to actively mine and actively use tertiary blocks. Therefore, Ethereum thinks that it is valuable.

In the management of mineral resources, all kinds of taxes, fees, funds and prices of mineral resources are often involved. What are the taxes and prices of mineral resources? How to correctly distinguish these taxes and prices? The author combs this concretely below
(1) resource tax. The purpose of resource tax is to regulate the differential income of mining enterprises e to the exploitation of different grades of resources, and promote fair competition among enterprises. Resource tax was originally a progressive excess profit tax. In 1986, oil resource tax was levied according to proction quota. The Provisional Regulations on resource tax (Decree No. 139 of the State Council) issued in 1993 stipulates that resource tax shall be levied according to the proction quota (2) mineral resources compensation. Mineral resources as resource assets, the use and development of such resources, must pay a certain fee to its owner. Mineral resources compensation fee is the fee paid by the mining right owner to the owner for the use (exploitation) of mineral resources. The compensation fee for mineral resources was set up in the mineral resources law of 1986, but it was not collected until 1994. The regulations on the administration of the collection of mineral resources compensation fees (Decree No. 150 of the State Council) promulgated in 1994 stipulates that the mineral resources compensation fees collected by various localities in accordance with a certain proportion of sales should be timely and fully turned over to the central finance, and then shared by the central and local governments in a certain proportion at the end of the year. The specific distribution ratio is: the proportion of the central government to provinces and municipalities is 5:5; The proportion between the central government and the autonomous region is 4:6 (3) exploration right and mining right royalty. The royalty of exploration right and mining right includes the royalty of exploration right and the royalty of mining right. The royalty of exploration right refers to the royalty that the state transfers the mineral resources exploration right to the exploration right holder and collects from the exploration right holder according to the regulations. The royalty of mining right refers to the royalty that the state transfers the mining right of mineral resources to the mining right holder and collects from the mining right holder according to regulations. The royalty of exploration right and mining right is charged according to the area of the mining area. The royalty of exploration right is calculated according to the exploration year and paid year by year according to the area of the block. From the first exploration year to the third exploration year, 100 yuan per square kilometer is paid every year; From the fourth exploration year, an annual increase of 100 yuan per square kilometer, with a maximum of 500 yuan per square kilometer; The royalty of mining right is paid year by year according to the area of mining area, 1000 yuan per square kilometer per year (4) the price of exploration right and mining right. The price of exploration right and mining right includes the price of exploration right and the price of mining right. The price of exploration right refers to the price that the state transfers the exploration right formed by its investment in exploration to the exploration right holder and collects from the exploration right holder according to the provisions; The price of mining right refers to the price that the state transfers the mining right formed by its investment in exploration to the mining right holder and collects from the mining right holder according to the regulations. The price of exploration right and mining right shall be paid in one time or by stages on the basis of the appraisal price confirmed by the administrative department of land and resources under the State Council. However, the payment period of exploration right price shall not exceed two years, and the payment period of mining right price shall not exceed six years(5) funds and deposits established in pilot areas. In April 2004, the State Council took Shanxi Province as a pilot project of sustainable development of coal instry, approved Shanxi Province to collect coal sustainable development fund, withdraw deposit for mine environment treatment and recovery, and establish coal mine conversion development fund, aiming at promoting sustainable utilization of coal resources
(6) royalty According to the provisions on the payment of royalties for the exploitation of offshore oil resources (Order No. 1 of the Ministry of Finance) and the Interim Provisions on the payment of royalties for the Sino foreign cooperative exploitation of onshore oil resources (Order No. 3 of the Ministry of Finance), the Chinese and foreign enterprises engaged in the exploitation of offshore oil resources in accordance with the law on the continental shelf and other sea areas under the jurisdiction of the people's Republic of China, and Chinese and foreign enterprises engaged in the cooperative exploitation of onshore oil resources within the territory of the people's Republic of China shall pay royalties in accordance with the provisions. After the tax system reform in 1994, those who cooperatively exploit oil and natural gas resources will still pay royalties in accordance with the original provisions, but will not pay resource tax. In addition, in 1994, the former Ministry of Geology and mineral resources made it clear in the reply to CNOOC's "letter on confirming that the compensation fees for mining offshore oil resources in China's sea areas will not be levied repeatedly" (No. 156 of the Ministry of Geology and mineral resources), Mining right holders who pay royalties for the exploitation of offshore oil resources in China's sea areas in accordance with the provisions of the "provisions on the payment of royalties for the exploitation of offshore oil resources" and the "Interim Provisions on the payment of royalties for the Sino foreign cooperative exploitation of onshore oil resources" shall not collect the compensation fees for mineral resources repeatedly Second, the specific form of paid acquisition of exploration right and mining right should be clarified, The specific forms of paid acquisition of exploration right and mining right include the following three types:1. Fees for the use of exploration right and mining right
the first paragraph of Article 12 of the administrative measures for the registration of mineral resources exploration blocks (order No. 240 of the State Council) stipulates: "the State implements the system of paid acquisition of exploration right. The fee for the use of exploration rights shall be calculated according to the year of exploration and paid year by year. " Article 9 of the measures for the administration of mineral resources mining registration (Order No. 241 of the State Council) stipulates that "the State shall implement the system of obtaining mining rights with compensation. The royalty of mining right shall be paid year by year according to the area of the mining area, and the standard is 1000 yuan per square kilometer per year. " In June 1999, the Ministry of Finance and the Ministry of land and resources jointly issued the notice on printing and distributing the administrative measures for the use fee and price of exploration right and mining right (CZZ [1999] No.74), which clearly defined the use fee of exploration right and mining right. According to the above provisions, it can be seen that since the amendment of the mineral resources law in 1996, the important manifestation of the system of paid acquisition of exploration right and mining right is that the state collects fees for the use of exploration right and mining right from the holders of exploration right and mining right
The first paragraph of Article 13 of the administrative measures for the registration of mineral resources exploration blocks stipulates: "if an applicant applies for the exploration right of a block funded by the state and whose ore procing area has been proved, the applicant for the exploration right shall pay the exploration right use fee in accordance with the provisions of article 12 of these measures, It shall also pay the price of the exploration right formed by the state funded exploration confirmed by the evaluation; In accordance with the relevant provisions of the state, the price of exploration rights may be paid in one lump sum or in installments. " The first paragraph of Article 10 of the measures for the administration of mineral resources mining registration stipulates: "if an applicant applies for the mining right of the state funded exploration and has verified the origin of the mineral resources, the applicant for the mining right shall pay the mining right fee formed by the state funded exploration in addition to the mining right use fee in accordance with the provisions of Article 9 of these measures; In accordance with the relevant provisions of the state, the price of mining rights may be paid in one lump sum or in installments. " In June 1999, the Ministry of Finance and the Ministry of land and resources jointly issued the administrative measures for the use fee and price of exploration right and mining right, which also clearly defined the price of exploration right and mining right. According to the above provisions, it can be seen that there is a strict boundary between the objects of collection of the price of exploration right and mining right, that is, the applicants who apply for the exploration right and mining right funded by the state and have proved the ore procing areas According to the notice on printing and distributing the measures for the administration of the bidding, auction and listing of exploration and mining rights (Trial Implementation) issued by the Ministry of land and resources, after the bid winner and the bidder are determined by the way of bidding, auction and listing, the competent department shall cooperate with the bid winner and the bidder The bidder signs the transaction confirmation. The transaction confirmation shall include "the price of exploration and mining rights and the time and method of payment of the price of exploration and mining rights". Although the term "price of exploration right and mining right" is used here, which is the same as the second paid way mentioned above, the specific meaning should be different. Therefore, the author uses "price formed by transferring exploration right and mining right by means of bidding, auction and listing" to distinguish From the above concepts, the author thinks that the differences between the two are mainly reflected in the following aspects:(1) the scope of price application is different. There is a strict scope for collecting the price of exploration right and mining right, that is, when the state transfers the "state funded exploration right or mining right that has proved the ore procing area", it can collect the price of exploration right and mining right at the same time of collecting the paid use fee of exploration right and mining right. As long as the exploration right or mining right is transferred through bidding, auction and listing, the price of exploration right or mining right should be collected. The exploration right and mining right transferred by means of bidding, auction and listing include but are not limited to the scope of "state funded exploration and proven ore procing areas"
(2) the way of price formation is different. The price of exploration right and mining right is based on the appraisal price confirmed by the administrative department of land and resources under the State Council, that is, the confirmed appraisal price. The price formed by selling exploration right and mining right through bidding, auction and listing is the transaction price. In the bidding mode, it is the bid price of the successful bidder; In the way of auction, it is the highest bidding price of bidders; In the way of listing, it is the highest offer of bidders. It should be pointed out that the transaction price must not be lower than the determined base price for bidding and auction (3) the essence of price is different. The price of exploration right and mining right is subject to the appraisal price confirmed by the administrative department of land and resources under the State Council. The appraisal price is essentially the cost of national exploration investment, and once the appraisal price is determined, the specific amount of the price is determined; The price formed by transferring exploration right and mining right through bidding, auction and listing is the market price of exploration right and mining right. It is an agreement price voluntarily reached by both parties on the basis of the set base price. It is an important embodiment of the market allocation of mineral resources It is an inevitable requirement for mineral resources management to vigorously promote the paid use of mineral resources and give full play to the basic role of the market in the allocation of mineral resources. In practice, some places still charge the price of the applicant's exploration right or mining right on the ground of paid use of the exploration right and mining right, even though it does not meet the conditions of "state funded exploration and proven ore procing area". As the author pointed out earlier, the conditions for collecting the price of exploration right and mining right are very clear, that is, "the state invests in exploration and has proved the origin of the ore". For the exploration right and mining right that do not meet the requirements and are obtained by application, the paid use of mineral resources can only be in the form of collecting the use fee of exploration right and mining right
