In China, IPFs has been fermenting for three years, but the actual preaching cycle is far more than three years. In these three years, the final display of mining technology is in the test network and space race, and more importantly, the formal excavation after the main network goes online. Interstellar Infinity has been leading the instry in terms of computing power ranking and single-T mining efficiency, especially the single-T mining efficiency, which remains at the top level in the field of IPFs distributed storage
1. Different network architectures:
decentralized application (DAPP) runs on the distributed network, the information of participants is protected (or anonymous), and the decentralized operation is carried out through different people in the network nodes. Distributed network is made up of node computers which are distributed in different places and have multiple terminals. When any line in the network fails, the communication can be completed through other links, which has high reliability
traditional app needs services provided by third-party service providers, and can achieve wireless network access through mobile communication network, which belongs to the centralized network architecture mode
2. Different from open source:
DAPP applications must be open source. Most of the tokens issued by DAPP run independently rather than controlled by an entity. All data and records must be encrypted and stored on a public and decentralized blockchain
traditional app software, games, navigation and other applications are generally provided by third-party service providers, which should solve the problems of right protection and economic interests, and their programs are not open source
extended data
in 2018, a large number of new DAPP projects were launched. According to the statistics, there are about two or three thousand dapps in the whole network. According to the DAPP survey of fluence labs, 72% of DAPP projects were launched in 2018. This means that in the past year, the number of dapps in the whole network has more than tripled
of all dapps, more than 80% are developed on Ethereum, about 20% on EOS and less than 10% on Tron. It is worth noting that about 10% of the projects are developed on multiple main chains at the same time, while the number of dapps developed on other main chains is relatively rare
there are about ten projects based on gxchain, mainly small applications in block city
e to the decentralized accounting method, open and traceable data, intelligent contract to ensure trusted transactions and other characteristics of the technology itself, blockchain is a perfect match for various applications in finance, logistics and other fields. However, e to the market's low acceptance of blockchain technology and the incomplete development and basic conditions of related instries, the technology has not been widely used in related instries. However, some instries with concentrated indivial users are ahead. The game instry has a huge demand for users to buy and sell game equipment, and the game equipment belongs to digital assets, Transaction has financial attributes, and it is also an ideal scenario for the application of blockchain technology< br />
looking at the current domestic blockchain games, dozens of them have appeared in recent half a year, but most of them are pet nurturing games with pictures and words to explain the rules, which have little entertainment value. Some Internet reports also mentioned that it only takes about five days to a blockchain pet game. It can be imagined that the blockchain game copied by such a simple method is difficult to be well designed and even less attractive to players. There are also other types of blockchain games, such as real estate games. Users can use tokens in game scenes to purchase land, services and procts in the virtual world, obtain property rights, and build buildings on their own land. But this kind of game in the country to do more influential is rare< br />
the combination of blockchain and games is supposed to improve the convenience and effectiveness of game digital asset management with blockchain technology, so as to enhance the overall use experience of players. However, the current domestic mainstream practice is to find suitable landing applications for blockchain technology, and reluctantly implant blockchain technology with simple and crude games, This practice of "block chain for the sake of blockchain" undoubtedly deviates from the design intention of the game itself from the source, which is the pain point of the domestic blockchain game instry< br />
in fact, many popular games on the market do not have very complex design ideas, as long as the extremely simple operation can help white-collar workers relieve the pressure of intense work. Simple but not hasty. Users play simple games, designers often spend more time in the game development stage. For example, an Auckland miner game, which is popular in New Zealand recently, uses the mutual help between human beings and elves in the magic world to connect simple story clues, and takes the beautiful natural scenery of Auckland island under different geographical environments, such as forests, caves and glaciers, as the basis of game art design. Although the play method is simple, the picture is beautiful. Players can "hire" miners to dig gold coins with the game token. Of course, the gold mining capacity will vary with the miner's level, and different mining tools will also affect the gold mining effect. The game also has a "steal" gold coin mechanism, that is, players can invite friends to participate in the game, and in the case of friends "not in the mine", they can take the opportunity to steal the other party's gold coins, so as to quickly increase their wealth. Of course, "steal" also have a way, as long as the player requisition "guard dog" guard "mine", can avoid the loss of theft. This part of the game is very similar to the popular "stealing vegetables" game in recent years. Although it is not innovative, it caters to the interactive nature of social media, which is one of the reasons why the game can rapidly expand the overseas Chinese circle. For game users, this kind of game does not need to be thought-provoking, and they do not need to concentrate on it. Players can "steal" people's gold coins while chatting with others. I believe this kind of "secret joy" is also a small sense of achievement for many players to play this game< br />
of course, as a blockchain game, Auckland miners also provide game profit channels for players, that is, while playing the game, players can earn tokens by mining, and get appropriate returns while paying the time cost. This is also one of the important reasons why many blockchain games can attract a large number of fans< br />
the success factors of Auckland miner game are briefly analyzed, including simple game logic, interactive social attribute, token profit mechanism, and finally the art design of the game itself. The original intention of players to participate in the game is to get entertainment and relaxation from the game. Therefore, pleasing art design and game interface are also the key to the success of any game. At this point, Auckland miners game takes the beautiful natural environment of New Zealand as the background of the story, and has natural advantages, which will also help this game to become popular quickly.
No, all right. If block currency is used for trading in the game or something. It's likely to touch the penalty area. No contact< br />

KH - horizontal seismic coefficient 0.15 CZ - comprehensive influence coefficient 0.25 & 8706; I - acceleration distribution coefficient 2.0 wi - weight of sliding body 1295kn Qi = 0.15 × zero point two five × two × 1295 = 97.2kn III. code for design of highway reinforced soil engineering
horizontal seismic force E = g × tan ζ G=W ζ= 2.50 G - weight of sliding soil ζ — Seismic angle
e = 1295 × Tg2.50 = 56.5kn
based on the different algorithms of the above specifications, the second horizontal seismic force FH = 97.2kn is taken to check the anti overturning safety factor of retaining wall: KS = MP / (MA + MH) MP -- the bending moment of passive earth pressure and fulcrum force on the pile bottom
MA -- bending moment of active earth pressure on pile bottom. MH - bending moment of horizontal seismic force on pile bottom. Ks=(1290.938+3402.781)/(2811.451+97.2 × 8)
Ks = 1.308 >= 200, meeting the requirements of the specification.
I haven't played unchangeable for a long time, but it should be for RPG. However, it's not very useful. It's hard to find RPG and it's hard to make rockets. Moreover, RPG is not very useful in practice, but it should be able to trade with other players
