  • E-sports and casual game competition block chain
    IG won the championship a short time ago and burst the circle of friends. From the perspective of competitive games, the future use of cryptocurrency and block chain in video game industry is as inevitable as the combination of Internet and games. Until recently, most video games were played offline, and online mode was sometimes just added.Today, online games dominate.More specifically, Newzoo's 2018 global game market report predicts mobile games will account for more than half of all game revenue. Meanwhile, Newzoo's 2018 global e-sports market report predicts e-sports will generate about $900 million in revenue.The ratings of professional games are about 380 million people, and they watch more than 46 billion minutes of live games and other traffic every month alone. However, the video gaming industry will first accept blockchain or cryptocurrency. Will it become a casual game or e-sports game? The answer lies in the business model that powers gaming revenues. Cryptocurrency esports Crypto has made progress in gaining access to Esports.The united masters of America has announced its support for the first professional gaming championship.ChallengeMe tournament ChallengeMe contestants will compete for a total of $290,000 in prize money in Unikoin Gold (UKG), the company's native cryptocurrency, under the sponsorship of Mark Cuban's global gambling and Esports brand Unikrn. In a press release, Unikrn revealed that the challenger eme championship will last three months and will challenge fourteen European teams to compete in the anti-terrorism elite: global challenges. With more than 400 hours of gaming and broadcasts in eight languages, the tournament represents a serious shift in virtual currencies and assets in the online gaming space.It's not a one-time event;Unikrn, which last month won crypto-currency and legal betting licenses, has begun a long-term shift into digital assets. Mobile games let developers rely on microtransactions While "hardcore" gamers have neglected mobile games at an early stage, revenues from mobile developers such as Rovio, Supercell and King have brought this to the attention of traditional console and PC developers.Soon after, electronic arts, Square Enix and nintendo were among the companies that had long insisted on mobile gaming. These new mobile players are proving a freemium business model unheard of outside South Korea's online gaming market.Games and applications on mobile devices are developed and released in sprints using agile development methods.This allows them to be released into the consumer market and start generating revenue early in the development cycle. Mobile games are usually given away for free. Today more than 80 percent of games are purchased for free within the app, called microtransactions.If properly executed, these freesadd models are highly profitable - Candy Crush Saga and Clash of Clans, the two highest-grossing mobile games of all time, make about $1m a day. Anyone who plays a video game on a mobile device, PC, or console (I have to assume it's everyone from the statistics) knows the familiar format of gems or COINS purchased in the game.Using these currencies for actual purchases is a big deal for gamers everywhere. That's what gaming platforms like GameCredits and LootForge are trying to do, but developers and publishers like blizzard want to keep it in their ecosystems with proprietary digital currencies like WoW tokens. There is no way anyone can ever really make money to play video, except professionals.But there is still hope for video games and blockchains. Blockchain can take a game to the next level Blockchain is more than cryptocurrency.It also provides an immutable digital ledger that can be dispersed or distributed.Using blockchain technology, they can track video scores, statistics and assets on everything from first-person shooter games like 'call of duty' and 'Fortnite' to MMO games like 'Minecraft' and 'Fallout 76' on mobile devices, PCS and consoles. This could be a huge win for developers, who often have to deal with servers for Microsoft, SONY and nintendo, as well as Valve's Steam PC market and Google and apple's mobile market. Cross-playing is not easy when platform owners resist it.SONY balked in 2018 at having its PS4 players play alongside other console players.It eventually succumbed to bad media and in September issued a press release indicating that it was considering cross-gaming more of its games. And tracking digital ledgers is not the whole story - because etherlane's erc-721 is not an alternative token standard and the erc-1155 reference implementation, digital collections can be created, tracked, and traded on blockchains. Games like Fortnite and world of warcraft offer a wide variety of rare and valuable items. The boss rolls to determine the drop rate of items, which can be calculated by block chain to get a more powerful booty distribution system.It's not just money - clothing, weapons and other collectibles can be found in the game. The online black market for resources in some games has always existed within the game itself.Such as idea and OpenSea platform has been in the study of these systems, and use a virtual tokening Decentraland intelligent contract specifically for the concept of VR built a chain block. But let's not forget about the game's own distribution system.Piracy costs the video gaming industry $8.1 billion a year.Most games are now sold through digital keys, and the theft of these keys has destroyed Valve's Steam market (hackers lost 33 million game code in 2016) to developers like Gun Media (Friday's limited release of the 13th Kickstarter code) in February 2018. Anyone who buys games on the secondary market loses most of their valuable online functionality. Blockchain-based code tracking can help combat piracy.In fact, the public/private key trading systems used in blockchain can better protect the game code, and the digital ledger can help track down the people who use them. It's not clear whether blockchain or cryptocurrency infiltrates the game in the first place, but both technologies can gain acceptance before others.Miners and gamers will always be together in the battle for graphics CARDS on the powerful GPU, and now it's time to start working together.

  • With the Internet, do you still need blockchain?
    Blockchain is a field that makes money extremely fast, and it is also a field that is very close to human nature.Dare you join us?You, with what? To some extent, it is "money" that drives the progress of the society.In the current hot blockchain field, the growth rate of "money" is several times, dozens of times or even hundreds or thousands of times, and the change of a few percent is hardly a fluctuation in the currency circle. Blockchain is a field that makes money extremely fast, and it is also a field that is very close to human nature. Dare you join us? You, with what? With the Internet, do you still need blockchain? The Internet enables low-cost, borderless transmission of information. The low-cost transmission of information flow can not only improve the productivity level, but also improve the efficiency of the use of production materials, such as taobao, jingdong and other online shopping malls, QQ, WeChat and other instant messaging software, as well as remote real-time collaborative office and so on. But the Internet doesn't do that, it doesn't deliver value. Duang, blockchain appears.Make it possible to synchronize the value stream with the information flow. Bitcoin, litecoin, etherlane...A lot of "digital money". Blockchain, intelligent contract, consensus mechanism, decentralization...A whole bunch of technical terms. So what is blockchain???I don't know. He's like a newborn baby. It's too early to define him. But there is no denying that he has been the focus of the whole world.This is unprecedented. Block chain is popular hot degree, conceal tremendous bubble and risk. The value of blockchain has become a consensus. It is another disruptive technological revolution after the technological revolution of the Internet. In the future, AI, Internet of things and other technologies need the support of blockchain technology.We also see that so far, the blockchain field has emerged with real applications that integrate with people's lives. Block chain development up to now, itself is not lack of anything, just need time to precipitation and accumulation.For emerging technologies, especially the wave of technological innovation, on the one hand, it is necessary to speed up technological iteration, on the other hand, it is necessary to slow down to go steady, because countless historical processes tell us that ideas and practices are too advanced, easy to become martyrs.For blockchain enterprises, they must have faith and never give up their dreams of industries and fields. In the process of realizing their dreams, they must be legal, compliant and ethical. There is no escaping the topic of well-intentioned state regulation Long before, concerned branch is eyeing block chain.The central bank has long defined bitcoin as not a currency and not a transaction intermediary. In 2017, ICO and domestic bitcoin transactions were continuously banned.Basically, the country is negative to bitcoin and other digital currencies, and the domestic blockchain entrepreneurship is actually in a low ebb. Nor, of course, is the government blocking the trend.Now the central bank plans to study the issue of China's own digital currency.In addition, tencent and other large enterprises are also actively exploring block chain technology, interested people can closely follow these trends.In our country, it is certain that it is not wrong to read the policy while running. In the other direction, don't run. Blockchain is a revolution of value Internet.The core of blockchain is decentralization. What has human history been doing since ancient times? In essence, they all want to be decentralized but fail to complete it. They are always in a cycle of centralization.The founder of the COINS in the hearing of his greatness, through the human so much sacrifice and effort didn't do it, he used a code made it, although there is no see influence the actual concrete effect, but in this power must be deep and profound, the influence of human progress process is greatly reduced, and the future of society must be decentralized society, both in political and economic decentralization, this is a landmark, all good things will be real began. Architecturally, the blockchain design is beautiful, full of idealism and the glory of freedom. For the first time, people can trust each other without relying on anyone or organizations.If mankind can achieve utopia, the first step should be from block chain, it is not only the future TCP/IP... Do you want to "go into the sea"?With what Blockchain is an emerging industry. It is not easy to establish a foothold in the blockchain industry.At least we need to have all the preparations in the following aspects: 1. Knowledge structure Someone asked li xiaolai why you can grasp the dividends of bitcoin.As for li xiao, I know English and am interested in emerging technologies from abroad. I like to visit foreign technology websites frequently and find bitcoin. In these simple sentences, we found the basic knowledge structure requirements, English, scientific Internet access, scientific and technological knowledge. In fact, to truly participate in the blockchain industry, blockchain covers a much broader range of knowledge.Such as cryptography, economics, computer distributed systems, money science, finance, science and technology trends and so on. In fact, it is difficult for a person to be good at many fields, but only a few of them need to be cross-border combination, can form their own unique competitiveness.In addition, complementarity among team members is a good way to make up for it. Although it is very difficult and complicated to enter this industry, we believe that the threshold is too low for many people to do things, why can we succeed?The more difficult things, the higher the threshold of things, the more competitive and competitive barriers. 2. Ability to circle The so-called circle of competence does not conflict with the knowledge structure.Is the so-called coin circle a day, the world a year, in the coin circle can feel the rhythm is really too fast, as if opened the accelerator of life. Working in such an environment requires us to have strong learning ability.From the knowledge structure just listed, we can see that in order to gain a foothold in this industry, we must keep learning, constantly charging and constantly expanding our knowledge structure. To have the ability to resist pressure, the faster the rhythm, the greater the pressure.We sometimes really feel that people in the coinage do not sleep. At any time, there are people in the group to discuss, exchange information, explore problems and think about problems.This is the rhythm of money circle life, in this rhythm, the pressure is certainly greater. We should have a buddhist mentality.The so - called buddhist mentality has two meanings. First, look down on the harvest and avoid expansion.Second, look down on short-term volatility losses, long - term vision. Another mentality is to focus too much on short-term gains and losses, daily fluctuations in the disk can disturb his heartstrings.Heart always want to see dish stare at dish, rose immediately happy, fell panic not line.This mentality is also not allowed, do this line of work must take a long view, or you will find that short-term fluctuations will have a dramatic impact on your life. Share.As the saying goes, the more you share, the more successful you will be.In such a circle, their timely access to information, information a favorable wind direction, may be able to benefit others together.Sharing is also conducive to the condensation of their own contacts and core competitiveness. 3. Social circle Coin circle is also a pyramid circle, from the outside into the line, is the process of constantly going to the upper pyramid.The further up the pyramid you go, the more information you see. In the circle of block chain, the project side, capital side, retail investors, exchanges, media, technology, mining and other small circle layer small fields can be contacted more, the higher the circle layer can be contacted, the more ahead of the market to do some reaction.

  • December 10 market analysis | will appear effective rebound
    At present, the 4H level of bitcoin is going through C of ABC structure. C has a rebound basis, because the volatility is decreasing at present, but it still needs confirmation at 30M level.At 30M level, $3,650 is an important resistance level. Judging from the overall trend, today's decline is the main one, that is, short around $3,580, stop loss of $3,700, and target of $3,300. If the reversal can start around $3,300, then the reversal of C will begin, otherwise it will continue to be low.If there is a clear rebound sign at $3,300, place a small order around $3,300 with a stop loss of $3,200 and a stop gain of $3,750. The trend of yitaifang tends to bitcoin, but the market to a lot of weakness, the current market is going 30M level of the center, the probability will also hit a new low.It is recommended to short around $94, stop the loss at $98 and stop the gain at $80. Grapefruit because of the strength of the early decline, so the rebound is relatively strong, but the rebound has come to an end.Usd 202 is an important resistance level, and the rebound ABC structure has also gone through. Today, it is suggested to short around usd 2.1, stop loss usd 202, and target at usd 1.7. Today's market trend is still down, except for the relative strength of bitcoin, other currencies are likely to hit a new low, so the operation continues to be short. The above is personal advice for reference only Today's internal 1. People's Daily published the article "crack the problem of difficult and expensive financing for private enterprises".The article mentioned that the financial system should be further integrated with emerging technologies such as big data, machine learning and blockchain to reduce financing costs of private enterprises. 2. Presto, a south Korean blockchain startup, has filed a constitutional complaint accusing the government of unconstitutional its ban on ICO last September. Gabor Gurbacs, VanEck's director of digital assets, said on twitter that the SEC's decision to delay the bitcoin ETF had double standards. 4. Satoshi obamoto tweeted that in January 2019, he will start showing people how bitcoin can be expanded through the SPV system. Coin printing pool co-founder zhu farfa fa circle of friends said: bold predictions, may have been the bottom. In a meeting with putin, venezuela's President suggested that he could use Petro to buy oil. 7. The minister of finance of Chile recently indicated that government entities had made progress in developing encryption regulations. 8. In a speech, the director of the financial science and technology department of the financial authority of Thailand (SEC) said that the Thai government encourages the development of compliant blockchain companies in Thailand. Maddison holdings bought BITOCEAN, a Japanese virtual currency exchange, for 1.68 billion yen.

  • Why hasn't bitcoin soared in the recession
    Economists find that the United States will soon experience a recession.Many bitcoin speculators think the price of bitcoin will rise during the recession, but that may be wishful thinking.Cryptocurrency behavior depends on the type of recession the economy is in.In a typical recession, bitcoin would be sold off like any other risky asset, but it would thrive in a currency or sovereign debt crisis.Bitcoin can fight disaster, not recession;When inflation and trust in government decline, it is most likely to rise. The rough waters ahead The recession is defined as two consecutive quarters of recession, and we may already see early signs of selling: the s&p 500 fell more than 10 percent in October.Nouriel Roubini, one of the few economists to predict the 2008 housing crash, recently highlighted America's growing fiscal obligations on mortgages, student loans and credit-card debt.He noted that these factors are expected to exacerbate the next recession, which could be worse than in 2008.Roubini believes we will face a financial crisis by 2020. Other factors, such as a decade-long bull market in U.S. stocks and the fact that the federal reserve has raised interest rates three times this year, suggest the economy could soon experience a downturn.'two things are almost certain :(1) the U.S. economy will slip into recession;No one knows when. Is bitcoin a lifeboat? Cryptographers such as Anthony Pompliano have suggested "shorting bankers and using bitcoin as an antitrust hedge".They argue that because bitcoin is disconnected from the financial system and negatively correlated with the stock market, its price will rise if the stock market falls. Bitcoin has become increasingly tied to the s&p 500 this year (see chart).S&p has not actually had a negative correlation with bitcoin since late 2016, and even then the correlation fell between -0.1 and +0.2, indicating little correlation in either direction. Bitcoin seems to have less to do with gold than U.S. stocks: an interesting statistic, given that the "bitcoin will rise in the recession" theory seems to be based on its similarity to gold.This, by the way, is also a bad reasoning: gold does not thrive during recessions because its share price is lower than equities. While gold was a better haven than equities during the liquidity crisis, neither option was optimal. What will bitcoin do in a recession? Messari's Dan McArdle points out that the answer depends on the type of recession and the conditions that led to it.The two largest depressions in American history were deflation, and if history is any guide, there are likely to be mild to moderate recessions. There are two possibilities for a recession: 1. Mild to moderate recession (liquidity crisis) Sovereign debt crisis/currency crisis Bitcoin investments have underperformed in situations where a liquidity crisis is more likely, but they could outperform the market in a currency crisis. A mild to moderate recession (a liquidity crisis) is characterized by a demand for debt repayment and a transfer of cash to repay these debts.Loans are hard to come by, and people give up risky assets in exchange for dollars to pay down debt.This cash transfer reduces the value of risky assets.Bitcoin will be sold in dollars at prices consistent with all other mild to moderate recessions to date. While most people think tank economy is good news for bitcoin, it's too simple.The most likely thing to happen is that bitcoin behaves like other risky assets. This does not mean that the value proposition of bitcoin has been broken;In short, it will behave differently in different types of recessions.In some recessionary scenarios, it would not be an effective hedge. There are also scenarios where bitcoin, unlike stocks and cash, does well.However, liquidity crises during recessions are not one of them. They are the superstition of traders. The idea that bitcoin is a haven from inflation limits its usefulness.There are other positive aspects to bitcoin, including its ability to become a global digital cash that can be sent anywhere in the world in minutes.Most of the illegal production of assets is a hedge against currency inflation in the developed world;It's time to stop supporting the existence of bitcoin to save us from the myth of recession.

  • Micro disclosure | coin ring ups and downs, you should know
    Do you know how cryptocurrency exchanges work?Do you believe in their commitment to the safety of your assets?When hackers steal encrypted assets, encryption transactions all into a few master prevention?The latest news is chilling: only 46 per cent of the world's cryptocurrency exchanges meet the required security parameters, while the remaining 54 per cent are believed to have substandard security measures, exposing hundreds of thousands of traders and investors. Since 2010, $1.3bn has been stolen from hacked cryptocurrency exchanges, but it appears exchange operators are still failing to take security seriously.ICO ratings published by the safety report in determining the safety rating when considering the following four factors: Console error User account security Registrar and domain name security Web protocol security Console error Console errors cause data loss before they occur, although this is usually not the result of a malicious attack, but rather a coding problem.The report found that 32 per cent of exchanges had code errors that caused operational failures. User account security To measure this, analysts created a separate account on each exchange and checked password security as well as email validation and 2FA measures.They found that 41% of exchanges allowed passwords less than eight characters long to be created and were therefore considered unsafe.Thirty-seven percent of exchanges allow users to create passwords using only letters or Numbers instead of combining the two, which is also considered a security breach. Worse, 5% of exchanges allow users to create accounts without E-mail authentication, and 3% lack 2FA (two-factor authentication, which requires users to confirm their logins through separate devices, is considered a fundamental aspect of capital protection). Registrar and domain name security Analysts use Cloudflare to identify security holes in their domain names and registrars. Here to consider many factors, such as the registry lock can prevent any use to communicate with outside people for domain name registry changes and registrar lock, and by strengthening the safety measures (e.g., needs to be more than just a authorization code) to prevent the domain name hijacking for domain access - role accounts are typically used to protect sensitive domain information is not leaked. Analysts recommend that the six-month expiration period for domain names allow complications such as ownership, and that the existence of DNSSEC has been tested to authenticate all DNS queries using encrypted signatures to prevent cache poisoning. Analysts found that only 4 per cent of exchanges used best practices in all these areas - only 2 per cent used registry locking and 10 per cent used DNSSEC, although no exchange completely ignored all five parameters. Web protocol security Use HT Bridge's WebSec to check the security level of the Web protocol.The analyst tested the HTTPS header in the URL, the x-sxx protection header, the content security policy header, the x-frame-options header, and the x-content-type header. Only 10 per cent of exchanges used all five security measures, 29 per cent used any of the above and only 17 per cent used content security policy headers. Analysts rank the 100 exchanges in most to least secure order.Coinbase Pro was the first to become the safest exchange, followed by Kraken.BitMEX, GOPAX, UB Coin and CDPAX account for the rest of the top 10. The report highlights the continuing problems with cryptocurrency exchange security, and notes that the encryption market and the nature of cryptoexchange security and regulation are "very attractive to hackers".

  • Blockchain trading may become a "lie killer" in the world
    Blockchain represents much more than digital currency.Blockchains could end up in every corner of the business, bringing with them intelligent contracts that can bind and secure any type of transaction online, from commodity exchanges to employee records services. Blockchain represents much more than digital currency.Blockchains could end up in every corner of the business, bringing with them intelligent contracts that can bind and secure any type of transaction online, from commodity exchanges to employee records services. Money started flowing in that direction.IDC, an Internet data centre, estimates that global spending on blockchain solutions is expected to reach $2.1bn this year, double the $945m in 2017.The consultancy expects blockchain spending to grow by more than 80% a year to $9.7 billion by 2021. Where will all this money go?Smart supply chains may be one big aspect.Just recently, IBm and maersk line has released a block chain support platform for the shipping, computer world Lucas Mearian, its essence is a "end to end (the end - to - end) shipping solutions, giving all parties a single perspective of global trade, know the goods location and allow authorities to release its trend of electronic approval".Many more are in the pipeline.According to Bill Fearnley of IDC, "Fearnley says that" a lot of technology vendors and service providers are moving in tandem and collaborating in alliances such as enterprise etherlane and ultrabook, which aim to develop startup project solutions to improve post-transaction processing, track and trace supply chain freight, and audit and compliance transaction records."Blockchain costs will be most significant in financial services, distribution and services, retail and manufacturing. It's time to start thinking about creative blockchain applications.In a recent interview, Michael Casey of MIT explored these issues in a new blockchain book he co-authored with Paul Vigna of the Wall Street journal.He said, for example, that the world food organisation was using blockchain to track food distribution.In an interview with MIT Rebecca Linke, he described how the world food organization operates a pilot program for 10,000 Syrian refugees that USES blockchain to focus on trade and ensure everyone gets food distribution."The world food organization has millions of customers around the world.Now they can have a single source of data.They are able to integrate multiple data sources into a complete transaction without requiring these onerous and time-consuming coordination processes. Casey points out that supply chains are a natural area to apply blockchain technology. "supply chains are a huge area of application because there is mistrust," he explains.You have a bunch of entities on the chain.They have a common goal, but they also have doubts, because every buyer wants to buy at a low price and every seller wants to sell at a high price.The idea is that people can be more open to the information they share if we create a common record that shows the transactions of the system.Blockchain helps reduce waste by highlighting information. Block chain distribution through block chain is also the goal of some large start-ups to enter the market.In Entrepreneur, Jonathan Long, a mainstream media in the market, points out that some start-ups use blockchain as part of their subversive value proposition.For example, a company called Fr8 USES blockchain networks to promote "the digitization of transaction records of relevant assets, including situations in which intermediaries and brokers strongly resist change.In the United States alone, trucks covered 29 billion empty miles last year.By applying blockchain, Fr8 helps simplify and organize the industry in a trusted way.Similarly, Long points out that ShipChain, a company called ShipChain, has launched a freight logistics platform based on blockchain."The platform focuses on end-to-end tracking and traceability and supports the integration of the entire supply chain and transportation companies.ShipChain is a member of the enterprise etherlane alliance (EEA) with Microsoft, as well as the block chain transport alliance (BiTA) with UPS and DHL. The MIT case treats blockchain as a "lie killer" because it relies on highly distributed information and authentication networks.Previously, "we had to rely on centralised institutions to deliver the truth.We may audit Apple's quarterly results every three months, but only if their records are true.And everything we did next was based on that.But blockchain is a distributed mechanism that can achieve this goal directly, which eliminates the ability of these large information transmitters to set the so-called real...If we implement transaction records that are considered absolutely true at any given time and we have accurate data in real time, then you don't need an audit.You don't need quarterly reports.I think this is probably the most disruptive technology we'll ever see at this stage.

  • Blockchain
    Can blockchain solve all problems?If it can't, does it have value?I don't think it's realistic to expect blockchain to cure all diseases, but that doesn't mean blockchain is worthless. Rarely in human history has a new technology been so controversial.This is the block chain technology, from the birth of controversy.Some people believe that blockchain is nothing but a hype tool with no real value.There are also those who believe that blockchain has real underlying innovation that will bring about real change.Can blockchain solve all problems?If it can't, does it have value?I don't think it's realistic to expect blockchain to cure all diseases, but that doesn't mean blockchain is worthless.Blockchain makes books more reliable through distributed bookkeeping. Even if there is a problem with the input data of blockchain, bad behaviors can be found by combining with AI or big data analysis.Blockchain will get better and better. Some people think that this is contradictory. Isn't it true that blockchain can solve the trust problem?The transaction chain connects farmers, miners, component manufacturers, commodity manufacturers, transporters, wholesalers and retailers, who are all involved in the transaction chain of global trade. However, the trust problem of block chain creates frictional, inefficient and opaque systems on the transaction chain.Since this is an immutable distributed ledger, they add, all you have to do is "input immutable garbage, output immutable garbage."That's a good question. It points to the key challenges facing the technology as it moves toward glory.But this so-called "last mile" problem is also a vampire problem.If we dig deeper, it provides a useful framework for understanding the true power of distributed ledgers and blockchains. First, no one should think of blockchain as some sort of "distrusted" utopia.No such society has ever existed.If it did exist, it would hardly be utopia. The same is true of blockchain ecosystems.Bitcoin and other unlicensed payment systems exchange value entirely on the chain in native cryptocurrencies, rather than on unreliable off-chain data, such as reports from factory floors. These vulnerabilities exist not only in the issue of detailed records of centralized exchanges or wallets, but also in computing devices used to manage encrypted assets.Users must trust the manufacturer and others who have access to their equipment and internal parts and components, as these people have access to the equipment before the user owns it. That's the nature of the world.Trust is everywhere, all the time. We're only dealing with one layer, but this layer is critical So why use a blockchain solution?Answer: because while it doesn't solve all problems, it does have the potential to improve an important trust issue in socio-economic structures. If we have a system that reliably records a series of state changes in a particular data set, it is impossible to modify it unilaterally, regardless of intent or purpose, without the agreement of others.In this way, we can remove this layer of uncertainty from the multifaceted trust process at the heart of any economic community.I think that's progress. Let's face it: spreadsheets and enterprise software solutions don't solve any enterprise data management problems.But they do optimize. In this case, we are trying to improve the specific layer of trust is not ordinary old layer, it can be said to be the most important: ledger. Books are vital to society.It is no coincidence that they appeared in the dawn of civilization about 7,000 years ago.In creating records of transactions that different people can refer to, communities form Shared facts, an accepted basis on which they can collaborate and exchange money.(note: we are not talking about an absolute truth or fact, but a fact that is fully accepted and agreed upon.)Books play a vital role in solving the problem of mistrust between us. The problem is that because we have to trust centralized ledger administrators to define Shared facts, another vulnerability enters a very important record-keeping layer.This is where the value proposition of decentralization lies. In the process of weakening the power of centralized bookkeeping administrators, it makes the Shared fact of distributed bookkeeping records more reliable and powerful. Ironically, given all the talk of "no trust" or "trust minimization," the result of any effective blockchain solution should be to strengthen our collective trust with each other, not undermine it. Find patterns of bad behavior With a data log that everyone trusts, you can do a lot with it, even if you don't necessarily trust the people who input the data.For example, you should even be able to use it to save the same data sources that are not necessarily trustworthy and to clean up bad data sources.When we combine decentralized, non-tamper able ledgers with other information management tools, such as data analysis and AI, the prospects for availability are further enhanced. Suppose there is a workshop worker in the supply chain who has so far been far more scheming than anyone else, who has been recording the fallacy of his output in a way that no one else has noticed.His bad behaviour may be hard to spot with the human eye, but it is vulnerable to computers running sophisticated network analysis.It exposes prototypes in the big data schema. Now that they have consistent order, tamper-proof, and generally accepted data entry records, computers can more easily detect anomalies and danger signals.Not only humans but also devices can be tested in this way, creating feedback loops that iteratively enhance trust in the system as a whole. So blockchain is not perfect, it can also store garbage.However, in many cases, with it, it will become better.We may even find that it gets better and better.

  • BCH is going to branch again?Bitcoins split into bitcoins
    1. The background of bitcoin bifurcation As the ancestor of virtual currency, bitcoin has become a behemoth with a market value of more than 900 billion yuan after nine years of development since it was proposed in 2009. At the same time, it has driven the development of the whole block chain industry. However, almost every bitcoin trader has encountered these problems in the trading process: the transaction confirmation time is long and the account arrival time is slow;High transaction costs, small transactions are difficult to carry out;The price is too volatile to use bitcoin as a daily payment currency.In this context, bitcoin bifurcation emerged. What is bifurcation? Bifurcation is the creation of alternative versions of blockchains that run simultaneously in different parts of the network.In a sense, we can think of it as an update of software code. In short, if all users are willing to follow the original rules, the rules will never change and the blockchain will never branch.But bifurcation occurs when there is a major disagreement in the user's consensus or when the basic rules governing the protocol need to be changed. Three, fork coin The blockchain network is permanently divided into two independent chains, and the new currency generated in these two chains can be called bifurcated currency. The two split chains share all the trading data before the hard fork.So in theory, users who held the digital currency before it was hard forked could get an equal amount for free. Iv. The mainstream bitcoin bifurcation currency in the market at present Bitcash - bch-bitcoincash Background: On July 21, 2017, bip91, the bifurcation scheme of bitcoin, has been supported by the entire network computing power. It is unanimously agreed to conduct isolation witness upgrade first and upgrade the block size of the underlying block chain to 2m within 6 months.However, "disruptors" have emerged -- viabtc, the mining pool owned by mining giant bitcoin mainland, has prepared a hard forked system to launch "bitcoin cash" based on the original chain of bitcoin. On November 2, OKEX, minan and other exchanges successively issued a notice that the charging and lifting of BCH would be suspended on November 15, and BCH hard bifurcation would be supported on November 15.BCH began to pull the evening 2, up nearly 40%.BCH pull up led the active capital to return to the mainstream currency, the early market hot shanzhai unpopular currency fell significantly. BCH itself is the bifurcated currency of BTC, which is commonly known as bitcoin "crown prince".The small block capacity of BTC itself has affected the speed of transfer during transaction. The community has proposed different solutions: for example, the community has been unable to reach consensus on increasing block capacity and using isolated witness.After master a large number of bit-computing power of wu jihan, jiang zhuoer and other mine bully started the fork.On August 1, 2017, bitcoin block 478,558 was officially bifurcation, the birth of BCH, with the support of big brother, BCH market value has always been in the top five, has a place in the currency circle. On November 15, coming hard bifurcate, more is the product of BCH community dispute, BCH's largest mineral pool CoinGeek and chain blocks nChain support a currency cash network client new version BitcoinSV (hereinafter referred to as BSV), and said to return to form in BCH COINS of the original agreement, only allowed to do chain capacity upgrade, and large one pace reachs the designated position directly on the 128 m block.BitcoinABC, represented by wu jihan, believes that the underlying protocol can be constantly innovated, and the current 32M block is enough to be used, and it is also enough to expand capacity in the future when needed. In addition, bitland community believes that BCH needs to keep pace with The Times and integrate more functions like ETH's intelligent contract with Ethernet, so as to solve future market demands, including issuing digital assets.The community represented by the CW, however, believes that it should "firmly" follow the white paper's ideas and support BCH to continue to expand its capacity, and that it should not do more functions like ether square in bitcoin. Question: 1. The principle of decentralization is violated: with the expansion of each block, the whole bitcash system will expand rapidly, leading to the need for stronger computational support for mining blocks.Skeptics worry that this could result in bitcash mining and trading being monopolized by some large groups, pushing independent miners out of the market. 2. Impact on mining revenue: some people worry that the mining union will stop mining blocks due to reduced labor costs, which will ultimately affect the development of the whole market. Gold -BTG-BitcoinGold Background: Bitcoin gold bifurcated bitcoin block chain as planned after block 491406 (2017-10-24 01:17:35 utc), which is a new digital currency obtained by hard bifurcation of bitcoin block chain.Like bitcoin cash, BTG has added sighash_forked(a hard forked security mechanism). Question: 1. No named code developer. The BTG codebase also contains 8,000 private pre-dug blocks (100,000 BTG).Developers may sell their pre-dug BTG on the open market. 3. On May 24, 2018, a malicious miner obtained at least 51% of the computing power of the whole network of bitcoin gold, temporarily controlled the BTG block chain, quickly withdrew the currency after recharging to the exchange, then reversed the block, successfully carried out a double-flower attack, and stole BTG worth more than 18.6 million dollar Bitcoin: lbtc-lightningbitcoin Background: Lightning bitcoin (LBTC) is a block chain based on dpos consensus mechanism formed by lightning team hard bifurcation bitcoin in order to solve the problems of miner centralization and network congestion in bitcoin.LBTC is an important part of bitcoin experiment. Question: 1. Low technical content 2. GitHub has no development contributor BitcoinDiamond diamond -BCD-BitcoinDiamond Background: Due to segwit2x's failure, bitcoindiamond (bitcoindiamond) was developed by evey and 007 teams overseas.Bitcoin diamonds use new working proof mining algorithms to enable people to mine bitcoins on their home computers. Question: The price is unstable, fluctuate greatly, platform spread is big, bring very big trouble to trade. Please pay attention for more information, UBexchange

  • A few Suggestions for novice coinage
    It is difficult to predict the rise and fall of digital currency. As investors, if we can master some knowledge and make more accurate and professional judgments, we can reduce the risk of digital currency investment to a certain extent.So, what aspects do we need to learn and improve? 1. Learn professional knowledge Never invest blindly, especially in block chain investment. First, enrich yourself, learn more professional knowledge, listen to more investment opinions of others, collect information through various channels, and then learn to judge the authenticity of information before choosing block chain investment projects. 2. Carefully select the trading platform to avoid the risk of currency charging and withdrawal At present, the digital currency investment has not been a sound legal protection, so the risk of investment must be clear, if there is no alternative trading platforms, may, when you don't know the platform is blocked or closed, there is no guarantee, so choose a relatively safe and stable trading platform, is responsible for their own money. 3. Select the issuing currency of value items All blockchain projects will have white papers. Before investment currency, please read the white paper carefully, and select value projects through various aspects of investigation and analysis, and make reasonable investment. 4, dare to hold for a long time In currency, digital currency can be divided into short-term and long-term investment, short time is not long, but easy to locked in, and can not have a market, long-term is in its very bullish on the currency under the premise of development prospect, of course, you can also choose to portfolio investment, for their study, seize its currency appreciation potential, no matter what style you choose, all need to pay attention to the trend, for being ready for the news, when reach the psychological price, this moves when it's necessary to make moves, don't be greedy.In view of the current environment of currency circle, non-mainstream currencies enter and exit as fast as possible because of the influx of capital. Currency circle, overnight rich, penniless, heavily in debt are possible, all depends on whether the individual is ready to psychological preparation, whether a reasonable investment, whether to keep the lonely, can withstand prosperity, whether to improve their own, live and learn!

  • Learn more about IPFS
    The name the first time I heard the interstellar file system, is feeling very tall, moment think of countless science fiction movie scene, in fact, although IPFS called star file system, but in essence, it is a network protocol, IPFS now due to technical limit has not been applied to a wide range, has been running for two and a half years, is not a theory of technology. IPFS, whose Chinese name is interstellar file system, was launched by Juan Benet in May 2014.Juan Benet's personal history is legendary. He graduated from Stanford university, and before he started the IPFS project, his first company was acquired by yahoo!In 2015, he created the IPFS, which received a huge investment in the YCombinator incubator competition, and set up a protocol lab.The lab team consists of 14 core developers and hundreds of code contributors from the community. We use hypertext media transmission protocol (HTTP) every day when surfing the Internet, checking our friends' circles and playing on the Internet. The domain names of websites always start with "HTTPs://", which is enough to show the dominant position of hypertext media transmission protocol in the Internet world. IPFS is essentially a distributed storage and transport protocol for content addressable, versioned, point-to-point hypermedia. The goal is to supplement or even replace the hypertext media transport protocol (HTTP) used in the past 20 years, hoping to build a faster, safer and freer Internet era. If IPFS is going to disrupt HTTP, the first change will be to cloud data storage services. There is no denying that both network disk and mobile hard disk have brought great convenience to people's access to daily data, but what cannot be ignored is that they also have natural fatal defects.For example, network disk, your data is stored in the central server of the operator, you want to pay for this storage, the operator can also delete your data at any time, or even directly arbitrarily shut down the service.It's like storing something important in a rented house, paying rent, and praying in horror that the landlord doesn't go through your stuff (but you can't avoid it, it's inevitable), or throwing it away, or even throwing you out.Say good lifetime use lifetime free?You really believe me?So even now, there are still a lot of users who don't want to store their data in the network disk anyway.Not be disrelish charge is tall (really quite expensive), however thing puts other people's home, how think not to rest assured. IPFS will solve this problem for us. It can greatly reduce the cost of data storage and improve the speed of data download. IPFS can be used almost everywhere where data storage needs to be optimized to improve efficiency.In essence, and BitTorrent IPFS system transmission technology (commonly known as "seed") we have in common, between IPFS team they call it the Bitwap will BitTorrent technology innovation, IPFS storage service in the form of cloud storage service, your data is stored in blocks of chain, and the server source code stored in one location or multiple locations of different cloud storage, cloud storage provides distribution of the dispersed in the global storage source of multiple nodes. Always say bye to 404 IPFS nodes essentially use computers on the network as storage devices for users.This way, there will be no downtime, your files will always be accessible, and you will never have to worry about losing your files.If one node fails, the others will always be online. So how does IPFS guarantee data security and transmission speed? Files in the IPFS network are given a hash value similar to our id number, which is unique and calculated from the contents of the file. Even if there is a punctuation change in the file, the hash value calculated is completely different, like a twin with a different id number. Therefore, there is only one unique file in the IPFS network. Naturally, the file will not be repeatedly stored or maliciously tampered with, greatly reducing the storage cost and waste of storage resources. This unique file, as long as the query of its hash value (id number), you can find, this design, than usual we find the file, much more convenient.We usually have to jump to several websites to find the file, and even some files in the website you do not know, will miss this file. When the file is uploaded to the IPFS network, the file is divided into many pieces, each of which is stored on a different hard disk in different parts of the country, with part of the file in each place.This hard disk is in your personal home, hard disk hundreds of gigabytes or even a few T, download files from everyone's home at the same time, the speed is much faster than the centralized storage, so it seems that IPFS is really a bit of a star feeling, the world's data storage hard disk built IPFS network star map. When one place is hit by such force majeure as earthquake, flood, flood, etc., IPFS system will immediately start the repair function, and restore the data stored in the disaster area to other places immediately.The data stored in the IPFS system is more secure than the cloud services you currently use. According to this feature, the files you upload will be permanently stored on the Internet and no one can destroy it.Similarly, IPFS is inherently resistant to DDoS attacks.Because all access will be scattered to different nodes, even the attacker himself will be one of the nodes. If you're storing a file that you don't want others to see, encrypt it before you save it to IPFS so that even if someone else has a hash of the file, they need a private key to view the data. Currently, there are only four cloud storage services based on blockchain.Sia, Storj, Maidsafe and Filecoin are respectively.All four services use the same mechanism -- they provide a platform on which all computer users can connect to rent out their unused hard disk space for a fee or token.In the future of blockchain technology development, maybe your spare hard disk resources can also bring you income.
