How much can underground mining earn
It's about 37 yuan
let me first introce the reward mechanism of bitcoin system
bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping
there are two parts in the reward for the block Miner: one part is the reward given by the system, which is called coinbase reward (also known as system issuance reward), the other part is the reward for bookkeeping, which is called miner's fee. The coinbase reward started with 50 bitcoins. For every integral multiple of 210000 blocks, the coinbase reward will be halved. This is what we often hear about bitcoin mining reward halved in four years
at the present stage, the reward of coinbase is 12.5 bitcoins. At the present stage, the average transaction miner fee received by miners for digging out a block is about 0.1 bitcoin (not fixed), that is to say, the average reward received by miners for digging out a block is about 12.6 bitcoin
about 99% of miners' rewards come from the system's coinbase rewards. According to the bitcoin system, one block can be g out every 10 minutes on average. The number of new blocks that can be g out in one day is 144 (60 * 24 / 10 = 144). At present, the number of bitcoins that can be g out every day is 1800btc (144 * 12.5btc = 1800btc). With the miner's fee of about 0.1btc per block, the total reward for all miners in one day is about 1814.4btc
In essence, blockchain is a decentralized distributed ledger database, which is a series of data blocks generated by using cryptography. Each data block contains the information of effective confirmation of multiple bitcoin network transactions
we know that blockchain is a decentralized system. Indeed, decentralization is a very important concept in the blockchain world. The design of many models (such as ledger maintenance, currency issuance, timestamp design, network maintenance, competition between nodes, etc.) depends on this central idea< br />
in the process, although you are trading with the seller, the transaction involves the third party, the Alipay, the seller and the seller. The transaction between you and the seller is centered around Alipay. Therefore, if the Alipay system has problems, it will lead to the failure of the transaction. And although you simply bought a mobile phone, you and the seller have to provide rendant information to the third party
so consider extreme cases. If Alipay run away or take money, do not admit your deal or the city where Alipay is driving away everyone, then you are tragedies.
the decentralized approach is much simpler. You just need to exchange money and mobile phones with the seller, and then both parties claim to have completed the transaction. It can be seen that in some specific cases, the decentralized processing method will be more convenient, and at the same time, there is no need to worry about the disclosure of their own information unrelated to the transaction. In fact, if only two people's transactions are considered, the benefits of decentralization can not be fully displayed. If there are thousands of transactions in progress, the decentralized processing method will save a lot of resources, make the whole transaction autonomous and simple, and eliminate the risk of being controlled by the centralized agent
decentralization is a subversive feature of blockchain technology. It does not need centralized agent and realizes a point-to-point direct interaction, which makes the information interaction mode of high efficiency, large scale and no centralized agent become a reality
I have been working in this company for one and a half years since May 2018, and I have been outputting works all the time. I seldom output some theoretical articles, so now I want to sort out my understanding of blockchain and how to do design after more than a year's work. There are also some preparations for those who are going to interview with blockchain companies.
now the price of the mine has depreciated by 90%, so it's good to dig up thousands of gold. It's not worth it.
2. I can earn so much even if I go to toss ah for 8 hours, but the market profit is too low to bother
3. At the present stage, Youming iron ore is easy to sell, with a group of 40. But you need a full class number. The lower class can't fly and dig fast.
however, the cost of such an advantage is huge. In order to deploy such a network, the bandwidth of participants is reced, and the data transmission between participants is slower, because all participants have to back it up
to sum up, the advantages of blockchain are so powerful that it may change the world, but its wide application is affected by two aspects. The first is the possible 51% crisis, that is, it can control more than 51% of the nodes in the system at the same time and modify the information. The second is high resource consumption. In order to deploy such a network, the bandwidth of participants is reced, and the data transmission between participants is slower, because all participants have to back it up.
at this stage, the application projects in the blockchain field are mainly divided into two aspects: one is the new business model that is more compatible with blockchain technology, such as cross-border payment, supply chain finance, proct traceability and other scenarios; The second is the application of the reform based on the existing centralized business, that is, the use of token economic incentive mechanism
with the development of technology, the number of application projects in this field is expanding rapidly, and many people believe that 2018 will be a year when blockchain will really combine with the real economy and break out. However, blockchain technology is still in the early stage of development, facing challenges including regulatory environment, lack of talents, technology awareness and so on
from the technical level, the application of blockchain technology to the actual instry scene needs to solve the problems of transaction speed, data consensus, node maintenance and so on. At present, bitcoin network can only process seven transactions per second, and the leading super ledger technology can only reach the level of 200-300 transactions; This is a long way from a centralized system with tens of thousands of transactions per second. In addition, the lack of relevant incentive mechanism in the field makes it difficult for participating nodes to operate orderly. From the regulatory perspective, although most countries actively embrace blockchain technology, there are no relatively perfect regulatory regulations and instry standards at this stage. Inappropriate regulatory measures may hinder the innovation and development of such emerging technologies
it is affected by many factors, such as the underlying technology needs to be further matured, the lack of intelligent contract public chain platform, the lack of ecological compatibility of all kinds of token, and the unclear government supervision; At present, the implementation of blockchain application projects is relatively slow, and the project quality is uneven. To this end, analysts said that compared with the general blockchain, the focus blockchain for specific scenarios and applications may be a breakthrough in the short term.
