U Network is the world's first decentralized content valuation and publishing platform, a content incentive network driven by fairness and value. The U Community is the first digital asset content platform built on UNetwork. UUU is used in development, marketing and operations, community and ecological construction, etc.

Project Vision

1. Solve the problem of discovering and pricing excellent content:When the content reaches a certain level, the UGC platform often becomes the "judger" representing the central organization. The staff of the platform have the right to kill the content for users. However, how to avoid "mistakes" in subjective consciousness is a kind of contribution respect for content contributors. By predicting the content value market, we will reasonably predict the value of the content and discover truly valuable content.
2. Solve the problem of unreasonable profit distribution:Some UGC products or platforms obtain income through user content, but do not give corresponding rewards to the creators of the content, or there is great irrationality in income distribution. By solving the content pricing, we can reasonably allocate benefits to platform users.
3. More decentralized content storage:Our U Network will support IPFS (InterPlanetary File System), a network transfer protocol designed to create persistent and distributed storage and shared files and decentralized file storage protocols and applications such as Genaro Network, making the product truly closer to the decentralized form.
We will build a decentralized UGC ecosystem driven by fairness and value based on the content value prediction platform created by U Network.

Project Highlights

1. Filter high-quality information
According to the meaning of information, the meaning of information is to eliminate uncertainty, or in other words, information is the unit of eliminating uncertainty, but at the same time, the cost of obtaining information is different for different people.
Faced with complex blockchain technology and dazzling blockchain assets, ordinary investors often do not have enough time, experience and ability to understand and judge projects, and many decisions in blockchain asset transactions rely on accurate and reliable information.
The U community directly solves the content evaluation problem with the prediction market, allowing valuable information to stand out and will perfectly solve the problem of screening high-quality information.
As a community born for blockchain, U Community will also make full use of the characteristics of blockchain, make full use of the convenience of blockchain payment in information acquisition, support paid questionnaires, paid subscriptions, paid private messages, paid questionnaires, rewards and other payment mechanisms to encourage the transmission of value and information, and support paid data transactions.
2. Content empowerment
The U community will empower content so that these users who produce content will get full benefits. U is built and operated in the early stage by a team with content genes. It will use blockchain technology to create a complete set of economic mechanisms that fully compete and return fairly for blockchain-related content, motivate individuals and empower content.
Excellent content producers can directly obtain Sugar rewards for high-quality content from fans and users on the U community, or can also obtain approval from the production of high-quality content, or discover excellent content to obtain Sugar rewards given by the system, directly achieving the purpose of allowing good content to obtain reasonable returns.
3. Fan Finance
In the traditional Internet era, the fan economy was popular for a while. The fan economy generally refers to the business income-generating behavior structured on the relationship between fans and followers. It is a business operation model that improves user stickiness and obtains economic and social benefits through word-of-mouth marketing. The beneficiary is often just the followers.
What the U community wants to create is fan finance, so that fans and followers can enjoy the benefits of value investment together.
In the U community, investors can archive trading strategies and transaction records when conducting trading activities, which facilitates review and performance management and makes better investment plans.
Excellent investors can choose to share their strategy combinations or trading actions into the community, and give relevant analysis for reference, and set viewing thresholds according to their personal wishes. Fans can pay to view to form follow-up investment. At the same time, excellent investors can also publish some investment strategies they predict and require users to consume Sugar to view. Other users will choose whether to view based on the publisher's past performance.
With the emergence of smart contracts, users can truly control their own assets while cloning trading strategies, fully cloning the operations of outstanding investors, and the smart contract automatically allocates a certain proportion of returns to the investment strategy publisher.
In short, the U blockchain content community we have built is a vertical community based on blockchain, a real value community that allows users to trade value, information and trust among them. Everyone is willing to trade valuable information and also allow truly valuable information to be disseminated.

Application Scenarios

Prepaid reading platforms such as online literature
On online literature platforms that need to be serialized, evaluating existing content and how to motivate subsequent content are all difficult. By introducing U Network's evaluation and reward incentive mechanism, excellent authors can obtain reasonable returns and long-term incentives.
Blockchain Content Platform
The traditional blockchain community has a complex content and various information is of varying quality. Using U Network's content pricing mechanism, truly good content can stand out. It can also use U Network's blockchain investment-related functions to bring a business model to the community.
Q&A Content Platform
Content monetization of Q&A communities like Zhihu and Quora has always been a problem. U Network's evaluation and reward incentive mechanism can allow outstanding respondents to get reasonable returns. U Network's value-based evaluation mechanism can also effectively alleviate the prevalence of content that cheats and cleverly, and prevent content that has real information from being obscured by these content with low value.
Blog category, forum category UGC content platform
Blogs and forums still occupy a large share of network traffic, which is the main way for ordinary users to publish content. Through the evaluation mechanism provided by U Network, the content incentive and reward mechanism of U Network network can be directly brought to these platforms, bringing more benefits to users who publish content and platform builders. Even issue digital assets based on U Network to activate the entire community.
Content aggregation platform
The platform can use the built-in content sorting function of U Network to filter out the best content to provide content aggregation functions such as Reddit.
Social Media Platform
Using U Network’s content incentive mechanism, the platform can build a social media platform with text content-themed content similar to Steemit, or Steemit in the vertical field.
Music, audio, short video, long video, live broadcast
Almost all content products involving content evaluation and fan interaction can bring U Network's content evaluation and incentive mechanisms to these content products, bringing more benefits to content producers and platforms.

Technical Overview

1. System Architecture
The network structure of our product is shown in the figure above, which includes three parts: a) Blockchain network verification node
b) Blockchain network service node
c) Nodes that provide web services
Blockchain verification nodes and service nodes together form the underlying blockchain network of the community, where the verification nodes are used to verify transaction information and generate blocks. The main users of the service node provide services to the upper-level applications. In the community system, the service node mainly serves the community web service nodes, providing necessary interfaces to achieve the combination of the community and the blockchain system. The community web service node is mainly a user-oriented web service, providing community user registration, posting and other functions.
The blockchain system supports custom methods and systems Sugar's coin minting, distribution, incentive, custom blockchain system, P2P network, distributed storage, consensus algorithm, smart contract, etc. It has a complete blockchain architecture and provides different node types, including:
a) Verification node: A node type in the P2P network, used to verify transactions and generate the next block
b) Service node: A node type in the P2P network, used to provide basic blockchain services, block information query, transaction information query, and system information query
2. Consensus mechanism
The consensus algorithm adopts an improved PBFT algorithm, which is a Byzantine consensus algorithm based on the voting mechanism, realizing the combination of the voting rights mechanism and Byzantine theory. This algorithm realizes the 1/3 fault tolerance rate of system nodes. Verification nodes are generated through voting mechanisms, and many users who hold the system Sugar have the right to vote and elect the verification node. The advantages of this consensus algorithm are as follows:
a) It will not fork, and the final confirmation of the transaction will be achieved with one confirmation, with excellent storage characteristics.
b) There is no need for mining to maintain system stability and save system resources
c) The block production time can be configured, suitable for a variety of scenarios with different transaction volumes. We expect it to be stable at about 6 seconds. d) Compared with traditional blockchain networks, it has obvious advantages in transaction processing speed
3. Transaction Agreement
In a blockchain network, transactions refer to a process of changing block data. The blockchain network can be expanded and software forward compatibility can be achieved by expanding transaction types.
Due to the diversity of UGC content product forms, on the basis of ensuring the security and stability of the blockchain system, we are particularly interested in the scalability of the system, because we cannot predict the possible business scenarios of decentralized UGC content product in the future. In view of this, in terms of architecture design, we have implemented the business model supported by the entire blockchain system by expanding transaction types without changing the core network protocols, consensus algorithms, storage structures, etc.
Therefore, we target specific decentralized UGC business models, we can implement specific business scenarios based on blockchain technology by adding new transaction types. The transaction types that the system will support mainly include the following:
a) Asset registration: used for minting.
b) Asset issuance: digital asset allocation in user system.
c) Asset Transfer: Basic asset transfer based on UTXO model.
d) Smart contract deployment: Deployment of contract codes by storing compiled contract codes to blockchain in transactions.
e) Calling of smart contracts: The call of the contract is realized by specifying the ID and parameters of the calling contract.
f) Asset locking: The asset owner realizes block height locking of assets through this transaction.
