  • Social network service is used as a space for information sharing and communication between people, which is the basic purpose of the Internet. Since the rise and fall of many social networking services, Facebook, Instagram and Twitter have the most users as of 2018. The companies that run the service make money by analyzing the user's lifestyle, interests and personal information, and then providing advertisements to the service users. This revenue model has turned social network service companies into giants. For example, Facebook's 2016 advertising revenue was about $ 26.6 billion, or about 97.3% of Facebook's total sales. Facebook's operating profit, driven by advertising sales, is growing rapidly every year.

Many donors use donation organizations such as the Red Cross and UNICEF, because donors generally cannot meet with their beneficiaries and make donations.
  • Blockchain is a trust-based network technology that can eliminate or reduce the brokerage costs brought by brokerage agencies. Bitcoin proved that money can be kept secure without an intermediary that manages money, and Ethereum proved that smart contracts do not require an intermediary for the conclusion and implementation of a contract.

In the case of advertising, if the advertiser can directly select the target of the advertisement and pay the advertisement fee to the viewer, the advertisement can be performed more effectively by excluding the brokering gain obtained from the intermediary. In the case of donations, the foundation can be minimized by solving the problem that donors cannot select donors.

  • This is pointed out as one disadvantage of the cryptocurrency ecosystem, and is being attacked by cryptocurrency skeptics. Therefore, blockchain researchers are making great efforts to solve this problem.
  • Bean and Leebin provide a way of agreeing the rules of distribution, rather than the rules of competition. That way, given that blockchain is a reliable data store, it is a consensus that measures value by the quantity and quality of data stored in the blockchain and distributes rewards through value. Livin can do this because he stores user-generated content in the ledger, not his transaction records.
  • a new method of consensus of value is used to determine and negotiate the value of a transaction.
  • Lee Bin offers a consensus model of value consensus, which can be transformed and used in various blockchains that measure value based on the quantity and quality of data recorded in the ledger.
  • Smart contracts provided by Ethereum issue the total amount of beans and then distribute the beans according to specific rules. It is expected that it will take some time for the Levin social network service to be published and enough users will be gathered. For example, when the total issuance amount is 15 billion, the token issuance model that follows the normal distribution curve is adopted to prevent the drastic drop in service by reducing the issuance amount until the mining completion point. The total amount of beans is 15 billion, and the amount of beans issued varies by year. In addition, for the continuous supply of beans, the Foundation purchases a certain amount of beans on the market every month to maintain the price of the beans. Percentage of purchases is determined monthly by the board of directors.

  • all contextual data produced during a specific time period is calculated for each user, and the amount of issue per hour (unit time mined) is reflected as the score ratio.
  • 10% of the mined bins can be allocated to the operating costs of the rebinds.
  • Table 1 shows the types of user context data, the weight of data points, and the maximum limit. The information in this table may change after testing.
  • the maximum limit is contextual data that can be produced by one user over an hour of unit time to prevent indiscriminate data production. Referrals allow two likes and dislikes, respectively, to prevent multiple dislikes from being recorded to increase your reputation score. Data that you set as private does not affect data scoring.
  • Reputation is a 10-point scale, and your reputation is determined by the volume of recommendations (likes / dislikes) of other users in the data produced. Therefore, the formula for calculating the data score (DataScore) is as follows.
  • Examples of calculating compensation are as follows. For example, if a total of five people scored 1000, 600, 500, 500, and 400 data points, the 1000 points earner would get a relative score of 0.33 points, and the amount of bins mined in unit time would be 10,000. In this case, 2,970 beans will be obtained out of 9,000 beans except 1,000 service operation costs. Beans acquired by users are distributed to content providers at specific intervals according to the policies of the Bean Operations Foundation.

  • the service allows users to receive donations or watch advertisements. The advertisements are exposed in the order in which the most advertising expenses can be obtained, and when the user watches one advertisement, the registered advertising expenses are deposited into the user's wallet. After watching the advertisement, the next higher advertising fee is replaced by the advertisement.
  • Levin users can query the data recorded at a specific location. Users can rate “likes” and “dislikes” specific content, with a limit of two ratings per hour. And one content can only have one recommendation per user. Recommendations are anonymous, and you can't view content that you set private. The user can search the contents recorded by the user on his main screen. There is also an 'Ineligible' item in the assessment, to remove social data such as advertisements or pornography. As the influence of the Internet platform expands, it is pointed out that corporate social responsibility is required. Regulatory moves to social media and portals are emerging in the US, Germany, the UK and France. In particular, Germany has enacted penalties of up to 50 million euros for social media operators who neglect ⁇ clearly criminal '' posts.
  • Livin can systemize corporate social obligations, rather than mandatory monitoring by law.
  • the user may make one 'unsuitable' recommendation at an hour. If social data receives a 'non-conformity' rating above a certain criterion, the user who posted the data will be fined. The criteria and amount of fines may be determined and announced at the start of the service.

  • Ad revenues in the past have been monopolized by ad brokers, while advertising on the Livin platform returns 90% of advertising costs to ad viewers, minimizing the cost of intermediation, as well as direct-to-peer connections between advertisers and viewers. Advertisement can be said to have been realized.

This is to solve the problem of inadequate analysis of advertisement effect, which is the biggest problem in the mobile advertisement market. In addition, it is possible to analyze the effects of marketing target selection. For example, it can be used as a reference for selecting marketing targets by comparing the effects of advertising with 20s and advertising with 30s. Livin will continue to provide effective advertising results to advertisers.

In other words, if a person produces a product directly to the rebind service and the consumer pays the cost, the customer can directly deliver or supply the service. In traditional commerce platforms, regional-based retail products are not easy to sell their products or services directly to various people.

Therefore, advertisers or commerce companies combine specific conditional search and send queries to the rebind platform, which then masks users who come from querying data based on the received queries and returns them to advertisers / commerce vendors.
