EOS is a public chain system at the bottom of blockchain developed by block. One, which is specially designed to support decentralized application of Commerce, and its code is open source

bitcoin is called blockchain 1.0 because it opens up the world of digital cryptocurrency and takes a decisive step from 0 to 1

Ethereum is known as blockchain 2.0, because it provides Turing complete virtual machine that can run smart contracts, bringing unlimited possibilities

and EOS is called blockchain 3.0, why? Two words: performance

The positioning of EOS is the slogan of its home page:

English: the most powerful infrastructure for decentralized applications

Chinese: the most powerful decentralized application infrastructure

EOS expects to be an enhanced version of Ethereum, a high-throughput intelligent contract platform

although Ethereum has complete functions, it is limited by its design choice. Due to the block output speed of 15 seconds, the transaction throughput is far from large-scale practical level, which is only about 30 ~ 40tps (transaction / s). EOS, on the other hand, has chosen a different technology route, with the goal of achieving a considerable million TPS, which is quite attractive considering visa's actual processing speed of 1700tps

consensus mechanism of EOS

the reason why the throughput of bitcoin and Ethereum is so low is that they are constrained by the application scenario they envision and the consensus mechanism they choose for the scenario - both of them assume that the environment in which the system runs is totally untrustworthy, so they both adopt the consensus mechanism of proof of work

consensus, as the name suggests, is to reach a unified understanding of something - for blockchain, something refers to the confirmation of the transaction - any node to submit a transaction needs everyone's approval

the pow mechanism currently adopted by bitcoin and Ethereum is the design of the legendary Nakamoto Tsung. Under this mechanism, in order to obtain the bookkeeping right and digital currency reward, miners need to constantly dig for the compliant hash value, and confirm and package the transaction data through the consensus of hash value. POW has no access threshold, and any node has equal rights to participate in bookkeeping. Of course, the probability of winning is related to computing power:

the price of ram is based on Bancor algorithm, that is, it is regulated by market supply and demand: if the supply of ram exceeds the demand, more EOS certificates are needed to buy ram, At this time, more EOS certificates can be obtained by selling ram

memory is a consuming resource, which cannot be redeemed and can only be bought and sold. Take the issue of currency on EOS as an example. At present, the issue of currency requires 20m of memory. An EOS can buy 20KB. According to the current storage price, issuing a currency will consume 1000 EOS. This is the source of EOS memory consumption

The

blockchain is a technical solution to collectively maintain a reliable database through centralization and distrust in the past
generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book. At present, whose system will keep accounts, wechat's account book is Tencent's account book, and Taobao's account book is Ali's account book. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology
now, blockchain technology will be very popular, especially in the financial sector. Ant finance, laikelib, Wanda, Ping'an and Minsheng have tried blockchain projects one after another, and European crowdfunding is in the forefront of using blockchain technology. The most successful case is digital currency

Bitcoin is a virtual cryptocurrency based on decentralization, peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. It was proposed by Nakamoto in 2008 and born in 2009

bitcoin does not have a centralized issuer, which is generated by the calculation of network nodes. It can be bought and sold on any computer connected to the Internet, and has a strong scarcity

CEO Zhang Ruimin pointed out that the implementation of Haier's e-commerce depends on the advantages of "one name, two networks": famous brand is famous brand, brand awareness and customer loyalty are Haier's significant advantages. "Two networks" refer to Haier's sales network and payment network. Haier's global sales, distribution, service network and payment network are all over the world. We don't believe that e-commerce will succeed without foundation, because there is no business process reengineering, no intranet and extranet application, no enterprise information application system, and e-commerce platform is no different from castles in the air

First of all, Haier has realized network management, network marketing, network service and network procurement in the aspect of instrial direction transfer. Relying on Haier's brand influence and existing market distribution and service network, it has laid a solid foundation for the transformation of e-commerce. In terms of management transfer, the pyramid management system of traditional enterprises can no longer meet the needs of market development. Therefore, it subverts the pyramid in the management mechanism and establishes a new process aiming at the market

2. The main goal of enterprises has changed from profit maximization to customer-centered and market-oriented. Within the enterprise, everyone should be responsible for the market, not the superior. Haier Group also set up logistics, business flow, capital flow three flow promotion headquarters. As the third profit source, logistics directly purchases from international companies, which reces the cost and improves the competitiveness of procts. Business flow reces costs and improves efficiency by integrating resources, while capital flow ensures the smooth flow of capital

Haier has a relatively complete marketing system. There are more than 40 telephone service centers, more than 10000 sales outlets, and even more than 60000 villages. That's why some websites have restrictions on where to place orders. Haier can deliver goods nationwide

4. Construction of Haier e-commerce platform. We do not want to hype concepts and themes, but to enter an integrated world economy. Therefore, Haier has invested more than 100 million yuan to establish its own it support platform to serve e-commerce

5. Prospect

Haier e-commerce platform will develop into a public platform, which can not only sell Haier's procts, but also sell other kinds of procts; It can not only meet Haier's own procurement needs, but also provide services for third-party procurement and distribution

6. Based on "one name, two networks", we will keep a zero distance with users and quickly meet the personalized needs of users.

the Internet era is an era of information explosion, and Haier needs to use information to develop. Through this website, Haier can collect information and feedback from a large number of users. The trust and loyalty of these users to Haier is Haier's greatest wealth

6. What is o2o
o2o, online to offline, combines offline business opportunities with the Internet, making the Internet the front desk of offline transactions. Through the Internet, the idle resources of offline (especially local merchants) are aggregated, and consumers screen and pay online, and then consume offline<

the development of o2o:

according to the data of consumption research institutions, the proportion of fast-moving consumer goods purchased from e-commerce channels in China reached 30% in 2013, 12% higher than that in 2011, and the penetration rate of first tier cities was as high as 46%. When the physical retail instry was strongly impacted by e-commerce, o2o transformation became a necessary change, The retail instry, which combines e-commerce with physical development, will be a powerful new force in the future. On the whole, the o2o market is divided into a number of local life service fields, including catering, movies, hotels, shopping, etc. at the same time, it is also regarded by the instry as another trillion level market after e-commerce. In the past year, all retail brands have increased their efforts in the o2o field, and restaurants and hotels have cooperated with the online map open platform; Intime department store and Ali jointly try Alipay wallet line experience; Wangfujing Department store, Haidilao and other enterprises also try Tencent wechat payment to cooperate. Even Shunfeng, a logistics giant, has started its o2o journey - Heke convenience store. The most eye-catching is the recently popular & quot; Teng million cooperates with o2o & quot; Big news has even pushed the word o2o e-commerce to the top of the list

opportunities for commercial real estate brought by e-commerce o2o

2. Continue to gather popularity and lead online customers to offline customers

3. Meet customers' shopping, information acquisition and other needs, and enhance customer viscosity< The o2o mode is not a simple internet mode, and the implementation of this mode is not a small challenge to the offline ability of enterprises

2. The key point of o2o mode is that the platform attracts consumers through online way, but the service or proct that is really consumed must be experienced offline by consumers, which puts forward higher requirements for offline service

3. Therefore, how to ensure the symmetry between online information and offline business services will become a key node to challenge whether o2o mode can really develop

4. If o2o mode attracts consumers with price advantage, how to balance the difference between online price and offline price, ensure the interests of both consumers, or pay more attention to which consumers can attract the maximum customer flow is also a difficult problem<

analysis of typical o2o cases

analysis of Suning e-buy o2o

o2o concept: "Suning's purpose of o2o is to take Internet retail as the main body, and to form the o2o mode of" combination of shop + e-commerce + retail service provider ", so as to form the unified standard of" commodity, price, promotion, payment and service "online and offline& quot;

7. Schramm believes that communicators and audiences are the relationship between communication and needs. Audience needs to be able to restrict communication: programs without ratings can't be run; newspapers without subscriptions can't last long; Communication can meet the needs of the audience: communicators and media provide the audience with necessary information; 1. Entertainment for the purpose of entertainment and novelty seeking; A virtuous circle can be formed between need and communication: communicators provide information needed by audiences, audiences receive and feed back to communicators, communicators change the content or form of communication.2840 in my opinion, communicators in the process of communication care too much about the needs of audiences (such as audience rating, click through rate, etc.), It has become an excuse for some media to proce vulgar communication content, but this kind of communication content is an instinctive demand related to human nature, so... Moreover, in the eye of market economy and today's popular economy, other rational, ecational background and accomplishment are all floating clouds. Otya's focus theory adapts to the pluralistic social view. The diversion and diversification of 1739 audience is bound to affect the communicators, and the non mainstream and non mainstream are thus proced. The focus theory is different from the mass society theory and the social view of European critical school. Communicators select the things that the audience needs or is interested in from the huge and complicated information database, and also bury and refrigerate some sensitive or unqualified things.
