Blockchain is still in its infancy
1. Germination stage: the real germination stage of blockchain was from 2007 to 2009. In 2008, a Japanese American with the pseudonym of Nakamoto first expounded a new fantasy report on electronic money in the form of a synonym on the cryptography discussion group, and bitcoin came out. As early as 2007, Nakamoto began to explore a series of new technologies to create a new currency. On October 31, 2008, bitcoin white paper was released, and on January 3, 2009, bitcoin system officially began to operate
the main technologies supporting bitcoin system include hash function, distributed ledger, blockchain and asymmetric encryption; It can be seen that these technologies build the initial version of the blockchain, and it can also be said that the blockchain is the underlying technology of bitcoin. During the three years from 2007 to 2009, bitcoin was an experimental stage in which a very small number of people participated, and the real commercial activities had not really started
2. "Geek" niche stage: here, "geek" refers to people who are crazy about Internet technology and take technological innovation as fashion and life. On February 6, 2010, the first exchange of bitcoin appeared. On May 22 of the same year, someone bought two hamburgers with 10000 bitcoins. On July 17 of the same year, the exchange Mt. GOx was established, marking the official inflow of bitcoin into the market. Nevertheless, the only people who can really understand and enter the market to participate in bitcoin trading are geeks who are keen on Internet technology. They discuss bitcoin technology on the forum, mine for bitcoin on their own computers, and then buy and sell bitcoin on Mt. GOx. Now these geeks have become billionaires
3. Market brewing stage: the price of bitcoin was $13 at the beginning of 2013, but on March 18 of the same year, the government of Cyprus closed the bank and stock market e to the financial crisis, which made the price of bitcoin soar, and the highest price rose to $266 in April. On August 20 of the same year, the German government confirmed the currency status of bitcoin. On October 14, China network announced the opening of bitcoin payment channel. In November, the US Senate hearing also confirmed the legitimacy of bitcoin. On November 19, the price of bitcoin rose to US $1242, forming a new high. Nevertheless, the foundation for blockchain to enter the mainstream social economy is not yet available, and the soaring price of bitcoin is only e to over optimistic expectations. The containment of China's banking system, the collapse of Mt. GOx and other events made the price of bitcoin continue to fall. At the beginning of 2015, the price of bitcoin has dropped below $200. From 2013 to the beginning of 2015, the public began to understand bitcoin and blockchain
4. The mainstream period of blockchain: on June 23, 2016, the United Kingdom left the European Union, the fifth nuclear test of North Korea in September, Trump's election in November and other events, the uncertainty of the world's mainstream economy led to the recovery of bitcoin with the function of risk aversion. The market demand was large, and the increase of trading volume made the price of bitcoin soar from $400 in 2016 to $20000 in 2017, The wealth effect of bitcoin and the transaction overflow caused by network congestion of bitcoin have led to the outbreak of other series of virtual currencies, as well as a variety of blockchain applications, resulting in the emergence of a large number of blockchain assets that are 100 times, even 1000 times and 10000 times, which has aroused the crazy pursuit of the world, Subsequently, the Chicago Mercantile Exchange launched bitcoin futures trading, marking that bitcoin has officially entered the mainstream investment proct series, and bitcoin and blockchain have entered the global attention
5. Instry landing stage: after the market frenzy in 2017, the virtual currency and blockchain have been adjusted in terms of market, supervision, cognition, etc. in 2018, returning to rationality. In 2017, many blockchain projects that follow the blockchain technology will graally die out with the cooling of the market, and the projects with real blockchain applications will be initially implemented. 2018 is not only the first year of the blockchain, but also a gold rush period for the blockchain. After the waves wash away the sand, what remains is relatively good gold
from the perspective of the history of blockchain development, blockchain technology is not yet mature and is currently in the growth period. The specific practical application of blockchain is only used in the financial field. It still needs a long way to go to apply blockchain from other instries. However, we should grasp the trend of blockchain and actively learn from the new field of blockchain.
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain
a block contains the following three parts: transaction information, hash formed by the previous block and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All nodes compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction.
in addition to solving the security problem, blockchain technology can also change the following areas:
1. In the future, music right distribution is likely to enter the stage of blockchain, removing the intermediate link, so that musicians can get more direct income. In the past, record companies or the Internet were required to increase user stickiness. There were a lot of fees in the middle of promotion or song playing, but not many were really given to the authors, because the original right was still in the hands of several major record companies
2. Writing right is the same. For example, you may have to find a publisher before. This right can't be sold many times, and the money given to the author is also very small. With blockchain technology, all users need to pay the right fee to the author, not limited to a single publisher. Previously, Mr. Li Xiaolai did the press one project, which is mainly aimed at right distribution
3. The Internet of things and blockchain technology will combine to proce the blockchain Internet of things (Biot). Blockchain Internet of things can greatly rece the risk of hacker attacks. With the help of blockchain Internet of things, it may be as convenient as mobile phones to obtain warehouse sensor data
Kevin Kelly's book out of control has become the wind vane of the development of the Internet. In his later book necessity, he also mentioned that "technology has a preference in nature, which makes it move in a certain direction. On the premise that other conditions are the same, the physical and mathematical principles that determine the development of science and technology will favor certain specific behaviors
the development of blockchain technology is an "inevitable" trend, and bitcoin and some valuable digital currencies are only proced because of one of the needs. Today's blockchain is like the Internet in 1994. The development of the times will screen out the best technology and procts. It's just a matter of time
now there are too many "pseudo blockchain" projects focusing on blockchain, because too many people blindly invest in them without understanding. I want to make a fortune in this market. Those people are aiming at leeks that enter the coin circle without learning anything. They casually make small packages on the open public chain, issue a coin, hold a roadshow and want to circle a group of people to come in. They want to run after they circle money. In fact, they have no actual technical content and can't solve any practical problems.
It's only in the first tier cities that we know about this technology, but it's not very widely understood, let alone in other tier cities. The banking sector is also preparing to apply blockchain technology, but it has not really been applied. The financial instry also needs to apply it, but I don't know when. To be exact, blockchain is only in the initial stage of trial in China
in China, the instry in which blockchain has been applied is network mutual help bar. As I know, network mutual help platform concentric mutual help is the first real blockchain landing application in China. Through blockchain and big data technology, we can eliminate the defects of traditional network mutual help mode and establish an open and transparent new network mutual help platform
you can download their blockchain customer service end to experience it

Pure: the strongest and most practical skills at present, with King PVP one & quot; Dad;, It is the mainstream from the middle to the later stage. The pure advantage, first of all, is stability, second, pure disregard for defense and evasion, and finally, many copies are pure to pass, which is really IMBA. If we really want to talk about the pure weakness, it is the weakness in the early stage, but this stage is very short and harmless
Critical hit: the pioneers of the web version have summarized that the best lineup in the early stage is to attack critical hit stream first. It's true that in the early stage, when everyone's defense is not high enough, the benefit of critical hit is far greater than that of pure attack. In the middle and later stage, when everyone's defense is high enough, critical hit is more likely to catch chickens
Recovery: there are two kinds of recovery skills (self and opponent). The two kinds can be divided into four kinds (self maximum health value, self current health value, opponent's maximum health value, opponent's current health value). Recovery is different from blood sucking. You can recover blood whether you hit or not. In the two categories, those related to their own health value are suitable for PVP, and those related to their opponents are suitable for PVE (some levels must have this skill). I won't go into details
Blood sucking: blood sucking is very weak, yes, very weak. Among the skills of blood sucking, the only one that can be put on the table is the strategy of the two soldiers and guards. The others are weak. However, Zika has been eliminated in the middle and late period, and everyone's defense is high in the middle and late period, so it can't suck much blood. The specific weakness of blood sucking lies in the following points. First, blood sucking can only be profitable if it is hit. Second, most of the blood sucking cards have low absorption rate, with only two soldier guards as high as 200% (but there is no egg use). Finally, blood sucking is a tragedy if it is hit on high defense, with less damage and less blood sucking
Disabled (weak): pvppve are practical, there is only one disadvantage, not necessarily (except Xiuji)
Seal: at present, there are too few and weak seal cards, so people who use seal are very rare, but this does not mean that the seal is weak. In fact, the seal is very strong. In PVP, who seals the other party first will get a great advantage, but the disadvantage is also very obvious. Seal is not a must, and the early effect is very small, and it can not be printed, so we can only wait and see the seal card coming out later
Copy: the stronger the enemy is, the stronger I am
Percentages: there are two kinds of percentages: the opponent's current level and the upper limit of the opponent's level. Among them, the current level is relatively funny (only Satan is OK). The percentage PVP is very weak, and the PVE is passable. It is not recommended to use this skill
Slash: PvE and PvP are very awkward. If you can't hit a person, you don't say it first, and the damage after hitting a person is often lower than that of general attack. There are only two cards available in this series
Backwater: it's similar to chopping, but it's more embarrassing than chopping. It can be defined as useless
Multiplier: note that this multiplier has nothing to do with critical hit. Even 350% is not critical hit. Very simple skills are generally attached to other skills. They can be regarded as a common attack with high damage. They can be used in the early stage, but they are weak in the middle stage
