Research on new algorithm of mineable X11

1.

According to the current difficulty calculation, we can dig about 1.012 Laite coins a day. This is the average calculation result in the mine pool. If there is an efficient mine pool or solo, maybe more

litecoin (abbreviated as LTC, currency symbol: 321;) It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world

lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three significant differences. First, the lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the lightcoin network is expected to proce 84 million lightcoins, four times the amount of money issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in lightcoin's workload proof algorithm, which makes it easier to mine lightcoin on ordinary computer than bitcoin. Each Leyte is divided into 100000000 smaller units, defined by eight decimal places

design purpose

it is based on bitcoin protocol, but it is different from bitcoin in that even at the present stage, it can efficiently "mine" through consumer hardware. Liteoin provides you with faster transaction confirmation (2.5 minutes on average). It uses hard memory and mining workload proof algorithm based on scrypt (an encryption algorithm). It is oriented to ordinary computer and graphics processor (GPU) used by most people. The litecain network is expected to proce 84 million currency units

one of the design purposes of litecoin is to provide a mining algorithm, which can be run simultaneously on the bitcoin mining machine. With the rise of application specific integrated circuits (ASIC) designed for bitcoin mining, litecoin is also closely following the technological evolution. But before the widespread use of litecoin currency, it is unlikely that there will be an application specific integrated circuit (ASIC) specially designed for litecoin

transactions

a peer-to-peer network similar to bitcoin handles lightcoin transactions, balances, and issues through a script workload proof scheme (when a sufficiently small hash value is found, the, A block will be created, and the lightcoin will be issued. The process of discovering the hash value and creating the block is called "mining"). The issuing rate of Leyte coins is reced by half every four years (every 840000 pieces) according to the proportional sequence, and finally the total number of LTCs is 84 million. Unlike bitcoin, the memory intensive feature of script makes it more suitable for "mining" with graphics processor (GPU). FPGA (field programmable gate array) and ASIC (application specific integrated circuit) implemented for script are more expensive than sha256 used for bitcoin

currently, lightcoin can exchange legal tender and bitcoin, most of which are through online trading platforms. Revocable transactions (such as credit card transactions) are generally not used to purchase Leyte, because Leyte transactions are irreversible, which brings the risk of refund. As of April 25, 2013, a Leyte is worth about $3.97 or 0.028 bitcoin. This makes Leyte the second largest electronic currency with a market value of about $35 million

client

litecain is a free software project released under MIT / X11 license, which allows you to run, modify and the software according to your own needs. You can also release a modified version of the software if you like

the software is released in a completely transparent form, and users can independently verify the binary version and the corresponding source code

mine pool

the lightcoin is generated by "miner's mining". Mining is done by hashing with computer graphics card. If the value of "mine burst" is calculated, the system will reward 50 lightcoins at one time. At present, the computing power of lightcoin is growing rapidly, and the miner can't find the mine through several computers. Therefore, it is necessary to join the mine pool, which collects all the computing power, It is estimated that the probability of calculating the "blasting" value is higher

at present, the well-known mine pools include BTCC (original bitcoin China) mine pool, waltc.net fish pool (f2pool), wemineltc, coinotron, silverfish, liteguardian, litecoin pool.org, etc. But at present, the highest income is f2pool. Recently, it launched lightcoin theory income + 10% of mine pool subsidy = your actual income, which has attracted the attention of many miners and the instry

data block chain

litecoin block chain, compared with its competitor bitcoin, can handle larger transaction volume. Due to the more frequent generation of data blocks, the network can support more transactions without modifying the software in the future
as a result, businesses can obtain faster transaction confirmation, and they can still wait for more transaction confirmation when they sell large value procts

In fact, digital virtual currency is far from the above. Forbes magazine listed the top 30 virtual currencies in the market by their total market value and price as of 10:00 a.m. local time on the 27th. Caijing.com and venture capital Post said that there are at least 60 kinds of virtual currencies currently traded According to the Forbes report, bitcoin ranked first in market value and unit price. It was the lightcoin designed by Li Qiwei, a former Google programmer, that won "erlianya". In the past week up to the 27th, the price of lightcoin rose rapidly from $6 to $26, a considerable increase. The third to fifth place in the total market value are spot money, nominal money and prime money. The report counted the 24-hour gains as of the 27th. Almost all of the 30 currencies rose, with the biggest increase of the quark currency, reaching 278.55%. The report also said that almost all virtual currencies have taken a ride in the current round of bitcoin's rise, but most of them have poor business, with 8 companies with a total market value of less than $1 million and 19 companies with a unit price of less than $1

2. The difficulty of mining will become more and more difficult with the decrease of quantity and the passage of time. For example, Gehua chain routing bar has sold 3000 reservation codes in advance, and only those who get the reservation codes can buy them. The mining pool started on March 31, and only 3000 people scrambled for those coins. The more difficult it is to dig the later coins, the higher the price of Gehua coins, so the more people who come first earn.

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 cost

③ 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 technology

4. 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 agreement

bitcoin 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

4. AA mine pool is a digital currency mining service platform. At present, it provides users with eight digital currency mining services, including bitcoin diamond BCD, Ethereum eth, bitcoin infinite BCX, dascoin dash, green coin VTC, mone (Japan) Mona, raven RVN and small zero XZC. It uses blockchain technology to provide management and settlement services for digital currency investment. In the future, it will enter the blockchain public chain and cryptocurrency market
starting from the current market situation and mine owner's psychology, AA mine pool adheres to the market-oriented concept, pays more attention to humanistic service and professional technology, and creates a new, simple, safe and stable mining service platform
technical advantages of AA ore pool:
purer mining mode: adopting algebraic average algorithm, the original PPLNs + distribution mode is better than the traditional PPLNs / PPS mode, and the income can be increased by about 20%
core driver upgrade: make blocks output faster, allocate tasks at millisecond level, adjust dynamic difficulty, and output blocks efficiently
Security and stability: distributed main network node servers are distributed in 24 cities around the world, with strong anti DDoS capability, ensuring efficient and stable revenue growth
ultimate experience: more optimized big data infrastructure, timely and rapid response, simple mining steps, easy to understand, easy mining, and enjoy the benefits.

5. Chinese Name: jiaozi coin

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.

6. I like to play Terran, so I usually start with 3 farmers mining, 2 farmers building altars together, then base building, 2 farmers building altars together, and 2 farmers cutting wood together to mine. Because Terran farms only provide 5 people, so I usually shift and build several, so the wood in the early stage is more valuable than gold coins. Of course, when the 5 farmers in the mine are full, they can do it There are several Terrans that can build barracks together by directly pulling wood. This is the advantage of Terrans. Although it costs more resources, there are risks and opportunities in everything.
I play orcs in two ways. The first one is to harass the first swordsman. I think this is the key. After all, the success of harassing or anti killing largely determines the battle The success or failure of the service is very suitable for the double barracks to start with 4 drudgery mining 1 altar building base to build the hardworking wood altar building. After building the hardworking wood altar to build the population, two barracks will be built to storm soldiers at the same time. Of course, ring this period, the population and gold coins are very tight, because as the strongest Orc infantry on the ground in the early stage, only gold coins and population are needed, so gold coins are more valuable for wood At this time, it's the second way to play the orc for the purpose of building the population. I'm usually the first prophet. The second way is the witch doctor. The main arms are infantry and shaman. The main arms are the drudgery from the 4 mining 1 altar. After the wood altar is built, the drudgery comes out to drive the population at the same time. Of course, if you're very strong, the two barracks in front of you can suppress the opponent I think it's just that the infantry are too fierce and don't consume wood.
I don't play much with the undead, because the pictures make me a little disgusted. It's usually the first DK. Four acolytes mine an altar, and then the barracks go out of the ground. The characteristic of the undead is that after the acolytes call out, they don't have to worry about it. The acolytes can do other things. I always think this is a abnormal setting It's more abnormal than the drudgery when the orcs were building. When you lead the soldiers to fight, if the ghost is holding the wood in his hand, you'd better let it go home first, or it's hanging up, it'll have nothing.
I like the dark night race, because the fighting is basically a special basic unit, the elves. They don't need to move back and forth to pick wood, which makes the dark night race more beautiful The dispatch is very flexible, which also makes up for the weakness of the arms attack in the early stage of the dark night. I usually dispatch the first attack. There are too many possibilities for the blind and the old deer to have the white tiger in the dark night. It depends on your opponent's situation. Start with 3 spirit mining 1 spirit altar 1 spirit. Go out to investigate the opponent's base, and hang it in the wood picker's house at the intersection It's the cheapest of all the basic units. By the way, if the swordsman comes to harass you, pull down the elves. The swordsman will not dare to be arrogant. Anyway, the elves are cheap, and the moon well will give our heroes blood and blue. Isn't it

7. Our company just participated in the development training. I also found a professional company from Langfang after a long time. It was the proctivity development of Langfang that took us to Miyun, Beijing to do it. The feedback was very good. They are public institutions with government background, so they seldom advertise, and few people know about it, so few people know about it, But a lot of people in the Development Zone who took the human resources examination went there to sign up, and they moved to the science and Technology Valley. Among them, the lecturer, Mr. Hu, is very professional and dedicated, and also very humorous. When sharing, they are very deep, and their coach is also very experienced. When I came back, I also found Mr. Hu's blog on the Internet. I saw their training photos and the blog articles he wrote before this year, which was very fruitful. You can search "Langfang Huyang" on the Internet. Their phone seems to be 0316-2235060, they also go to the seaside and CS, hope to help you!
