Anonymous mine pool
bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items[ 1-2]
PPS means that the gold you dig is stored in the mine pool, and then transferred to your wallet after a certain amount. The handling charge is relatively high. PPLNs is generally more common in p2pool. When you dig the mine, it is directly stored in your wallet, and there is no handling charge. At present, the more popular is p2pool, which is relatively safe at present, and it is also highly praised by foreign heroes
Background: the financial application of blockchain technology brings high investment value
2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles
1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:
in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost
2. Why can blockchain solve the above pain points:
blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs
3. The application of blockchain technology in the financial field mainly includes the following aspects:
① digital currency
among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits
Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost③ digital bills
④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost
The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points
in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it
Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall) In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreementbitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain
based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network
2. Master node network
the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan

mature period: 51 blocks
difficulty change period: 24 hours
transfer fee: depending on the specific number (up to 6.8 million oioc for a single transfer, The maximum transfer fee is 100 oioc)
RPC port number: 11112
P2P port number: 11111
the original intention of Jiaozi coin is to be a social reward currency that everyone can participate in together, so in the craziest period of domestic virtual currency, jiaozi coin is issued in the way of no pre dig and no ICO. But today, this kind of issuing method makes jiaozi coin encounter a bottleneck. Due to the low difficulty of mining and unstable calculation force in the early stage, the block proction speed is fast and the amount of money is large. At that time, e to time and other factors, the old people graally shifted their attention to jiaozi, which made that part of the coin become "dead coin", which made jiaozi not fully circulated, and also increased the threshold of later attention to jiaozi. This is not concive to the late development of Jiaozi
technically, some community members also put forward some perfect ideas for jiaozi coin, such as: 1. Our current wallet does not provide the function of choosing the installation path, so that some members with too small C disk can not install jiaozi Coin Wallet (except some awesome people). 2. Transfer is slow. 3. Open the wallet and load the card. 4. Logo is not novel enough, etc.
in view of the above factors, the development team of Jiaozi coin has made the following improvements:
first, when installing jiaozi Coin Wallet, add the function of selecting the installation path< 2. Replace the logo with a new one
thirdly, when the wallet is loaded, it is easy to crash when clicking the wallet< 4. Adopt new algorithm, increase the function of the mine prevention pool of the mine prevention machine, run the wallet software, and mine with one click< 5. Fine tuning the issuance mechanism to increase the difficulty ladder: 4 billion in the first year, 3 billion in the second year, 2 billion in the third year, 1 billion in the fourth year, and an additional 100 million in the fifth year to maintain the robustness and stability of the node network. The 4 billion yuan in the first year will be proced in advance by means of pre digging, which will be used to exchange the old jiaozi currency. In the next month (when the new wallet update notice is issued), you can exchange the exchange ratio of one old coin for several new coins for new jiaozi coin (the old wallet is expected to proce about 3.5 billion in one month, of which 3.5 billion will be used to replace the old coin, and the remaining 500 million jiaozi coin will be handed over to jiaozi coin fund, For the promotion and maintenance of Jiaozi coin, the address of the fund will be announced, and you can query the details of the fund wallet in the block browser)
6. Add the node reward mechanism: the new version of the wallet can not only mine fairly, but also build the main node of Jiaozi coin by purchasing a server with fixed public IP if your computer configuration is relatively low, All mines g through your main node will give you 15% reward< 7. Add anonymous sending function< 8. After the release of the new wallet, the jiaozi coin development team will start to develop the jiaozi coin application app.
