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

Project Vision

1. Solve the problem of excellent content discovery and pricing: When the content reaches a certain level, the UGC platform side will often become the "judge" representing the central organization, and the staff of the platform We have the power to life and kill the content generated by users, but how to avoid subjective "mistakes" is a kind of contribution and respect for content contributors. We will make a reasonable evaluation of the content through the content value prediction market, which will be very good Predict the value of content and discover truly valuable content.
2. Solve the problem of unreasonable distribution of benefits: Some UGC products or platforms obtain income through user content, but do not give corresponding remuneration to content creators, or there are extreme differences in income distribution. Big irrationality. After solving the pricing of content, we can reasonably distribute benefits to platform users.
3. More decentralized content storage: Our U Network will well support something like IPFS (InterPlanetary File System, InterPlanetary File System, which is designed to create persistent and distributed storage The network transmission protocol for sharing files and the decentralized file storage protocols and applications such as Genaro Network make the product closer to the form of decentralization.
We will build a content value prediction platform based on U Network to build a fair and value-driven decentralized UGC ecology.

Project Highlights

1. Screen high-quality information
According to the meaning of information, the significance of information is to eliminate uncertainty, or in other words, information is the unit to eliminate uncertainty, but at the same time , Different people have different costs for obtaining information.
In the face of 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 depend on Accurate and reliable information.
U Community directly uses the prediction market to solve the problem of content evaluation, making valuable information stand out, and will perfectly solve the problem of screening high-quality information.
As a community born for the blockchain, the U community will also make full use of the characteristics of the blockchain, make full use of the convenience of blockchain payment in information acquisition, support paid questions and answers, paid subscriptions, paid private messages, Paid questionnaires, rewards and other payment mechanisms encourage the transfer of value and information, and support paid data transactions.
2. Content Empowerment
The U community will empower content, so that users who produce content will obtain sufficient income rights. U is built and initially operated by a team with content genes. It will use blockchain technology to generate, distribute, and disseminate blockchain-related content. A set of economic mechanisms with full competition and fair returns will be established to motivate individuals and empower content .
Excellent content producers can directly obtain Sugar rewards paid by fans and users for high-quality content on the U community, and can also obtain approval through the production of high-quality content, or obtain Sugar rewards from the system for discovering excellent content, directly reaching The purpose of making good content get a reasonable return.
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 based on the relationship between fans and followers A business operation model that enhances user stickiness and obtains economic and social benefits in the form of word-of-mouth marketing. The beneficiaries are often only the concerned.
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 transactions, which is convenient for review and performance management, and makes better investment planning.
Excellent investors can choose to share their strategy combinations or trading actions in the community, and provide relevant analysis for people's reference, and set the viewing threshold according to their personal wishes. Fans can pay to view and 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 them. Other users will choose whether to view them based on the publisher's past performance.
With the emergence of smart contracts, users can truly control their own assets while realizing the cloning of trading strategies, completely cloning the operations of outstanding investors, and automatically distribute a certain percentage of income to investment strategy publishers by smart contracts .
All in all, the U blockchain content community we created is a vertical community based on blockchain, a real value community, allowing users to trade value, information and trust among them, and everyone is willing to contribute valuable information Make transactions, but also let real valuable information be disseminated.

Application scenario

Online literature and other paid reading platforms
On online literature platforms that need to be serialized, it is a difficult problem to evaluate the existing content and how to motivate the follow-up content. U Network's evaluation and reward incentive mechanism allows excellent authors to obtain reasonable returns and long-term incentives.
Blockchain Content Platform
The traditional blockchain community has a lot of content, and all kinds of information are mixed. U Network's content pricing mechanism can make the really good content stand out. It can also use U Network's blockchain investment-related functions to bring business models to the community.
Question and answer content platform
The monetization of content in question and answer communities like Zhihu and Quora has always been a problem. U Network's evaluation and reward incentive mechanism can make excellent answers obtain a reasonable return. U Network’s value-based evaluation mechanism can also effectively alleviate the prevalence of fraudulent praise and witty content, and prevent the content with real dry goods from being overwhelmed by these low-value content.
Blog and forum UGC content platforms
Blogs and forums still occupy a large share of network traffic and are the main channels for ordinary users to publish content. The evaluation mechanism provided by U Network can directly bring the content incentive and reward mechanism of U Network 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 U Network's built-in content sorting function to filter out the best quality content to provide content aggregation functions similar to Reddit.
Social Media Platform
Using U Network's content incentive mechanism, the platform can build a text-themed social media platform 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 the content evaluation and incentive mechanism of U Network into the These content products will bring 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 nodes
c) Nodes providing web services
Blockchain verification nodes and service nodes together form the underlying blockchain network of the community, where verification nodes are used to verify transaction information Validation and block generation. The main users of the service node provide services for the upper-layer applications. In the community system, the service node mainly serves the community web service node, providing the necessary interface to realize the combination of the community and the blockchain system. Community web service nodes are mainly user-oriented web services, providing functions such as community user registration and posting.
The blockchain system supports the minting, distribution, and incentives of the custom system Sugar, custom blockchain systems, P2P networks, distributed storage, consensus algorithms, smart contracts, etc., with a complete blockchain architecture, And provide 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 type in the P2P network Node type, used to provide basic blockchain services, block information query, transaction information query, system information query
2. Consensus mechanism
The consensus algorithm adopts an improved PBFT algorithm , is a Byzantine consensus algorithm based on voting mechanism, which realizes the combination of voting rights mechanism and Byzantine theory. This algorithm achieves a 1/3 fault tolerance rate of system nodes. Verification nodes are generated through a voting mechanism, and users who hold more Sugar in the system have the right to vote for verification nodes. The advantages of this consensus algorithm are as follows:
a) No forks, one confirmation is the final confirmation of the transaction, and it has excellent storage characteristics.
b) There is no need for mining to maintain system stability and save system resources
c) The block generation time is configurable and suitable for various scenarios with different transaction volumes. We expect the block generation to be stable at about 6 seconds Time
d) Compared with the traditional blockchain network, it has obvious advantages in transaction processing speed
3. Transaction protocol
In the blockchain network, the transaction refers to the A process in which block data is changed. The blockchain network can be expanded and the software forward compatible can be achieved by extending the transaction type.
Due to the diversity of UGC content product forms, on the basis of ensuring the security and stability of the blockchain system, we are especially interested in the scalability of the system, because the possible decentralized UGC content in the future We cannot predict the product business scenario. In view of this, in terms of architecture design, we have implemented the business model supported by the entire blockchain system by extending the transaction type without changing the core network protocol, consensus algorithm, storage structure, etc.
Therefore, for a specific decentralized UGC business model, we can implement specific business scenarios based on blockchain technology by adding new transaction types. The types of transactions that the system will support mainly include the following:
a) Asset registration: used for minting coins.
b) Asset issuance: user system digital asset distribution.
c) Asset transfer: basic asset transfer based on UTXO model.
d) Smart Contract Deployment: The deployment of contract code is realized by storing the compiled contract code in the blockchain as a transaction.
e) Smart contract call: By specifying the ID and parameters of the call contract, the call of the contract is realized.
f) Asset lock: The asset owner realizes the asset lock based on the block height through this transaction.
