Know More about Ulord Platform Architecture

The platform layer is the middle layer of the system, and plays a role as a bridge between application layer and base layer. The platform layer is categorized as support component and function component according to function. The support component provides functional components with basic function supporting. The platform layer is connected to blockchain of base layer through the functional components, providing the application layer with content distribution, sharing and payment service based on blockchain. The platform layer architecture is shown in Figure 2.

The core function of the platform layer is to build a basic network and service environment for content sharing platform. The main functional modules are as follows.

1.Ulord protocol

Ulord protocol is foundation of data transmission and service layer. The user based on Ulord protocol can upload resources quickly, search and purchase the interesting content. Ulord protocol realizes data distributed organization and accounting by defining a series of rules.

Distributed general ledger

The foundation of Ulord protocol is distributed general ledger, which is the foundation to generate encryption currency (UlordToken). The difference between Ulord system and traditional bank and payment system is the trust system based on decentralization. The trust mechanism is achieved through interaction of different participants. Through a distributed consensus mechanism, the transaction becomes credible and every accepted transaction will be recorded in blockchain, namely distributed ledger establishment.

Storage of internal data of Ulord blockchain is carried out in the key value pair. Each key corresponds to corresponding resource or its metadata name, and through the search based on key name, the content resources of user’s attention is returned. In addition to name and element of the stored resources in Ulord, the remaining data storage mode of blockchain is completely consistent with bitcoin block structure. But the block hash algorithm, block reward function, block size, total number of blocks and offline chain in this project are optimized.

Ulord network

Ulord network is the infrastructure to extend Ulord blockchain original accounting and payment function. Its main function is to provide the internet environment for the users in paying, searching, downloading and uploading resources in blockchain. Accessing to Ulord is a prerequisite for sharing and distribution of contents. Different from HTTP, DNS or other protocols of traditional www Internet, Ulord network is based on Ulord protocol for user communication and data exchange. In application form, Ulord acts as the background daemon. On the one hand, it monitors the data request of the machine; on the other hand, it monitors other nodes in the network and exchanges data with them.

2.Ulord network service

Ulord network service is based on Ulord protocol, integrated with P2P downloading, distributed file organization, intelligent learning and other technologies, which constitute different functional modules. Ulord network service can be flexibly set according to user’s needs. Currently, the services provided mainly include the following categories.

Fast content search service

Ulord protocol provides metadata-based resource classification function. Each user resource can not only follow traditional search function based on description information, but also has the following characteristics: a. It provides fast resource location based on content addressing, rather than based on domain name addressing. File has a unique existence. When a file is added to Ulord network, a unique encrypted hash value will be assigned to the content based on the calculation. b. In addition to storage of hash value, blockchain running on Ulord is extended to support the storage of hash value table of files. When each network access occurs, query of the address of the file on chain is conducted.

Content distributed storage service

Ulord uses P2P hypermedia protocol, making the internet faster, more secure and more open. All nodes in Ulord form a globally oriented, peer-to-peer distributed file system, and all computing devices with the same file system are connected together. Each file and all the blocks are endowed with a unique fingerprint called encryption hash. Each node, through determining of hash value of file, judges the redundant files, to ensure that the data is not redundant in a single node. In the search for documents, you can find file storage node by the hash value of file to find the file you need; next, Ulord provides the history version controller of file, supports multi-node using and saves different versions of files to achieve file’s history status tracking.

Secondly, file storage in Ulord is not mandatory for every node to store all contents. The owner of node can choose data to be stored. For the nodes stored with large amounts of content, Ulord billing model automatically calculates the user benefits through the data amount of downloading service of file, so as to encourage users to upgrade their hardware resources to provide more comprehensive data storage and maintenance service to obtain benefits.

Node customization service

Ulord node includes centralization node and lightweight node. The centralization node has client to store all historical records (all transactions of all users) of UlordToken, manages user’s wallet, and can directly start trading on Ulord network. Node can handle all aspects of agreement, achieve independent verification of the entire blockchain and any transaction, and provide completely autonomous and independent transaction verification. But the centralization node client needs to consume a lot of computer resources (for example, more than 125 GB disk, 2 GB RAM). The lightweight node is deployed with lightweight client. Lightweight client, known as simple payment verification (SPV) client, connected to the complete node of Ulord, and used to access the transaction information. But the local place is used for storing the user wallet, and is independently created, validating and transferring the transactions. The lightweight client and Ulord are directly mutual without intermediary.

BitTorrent peer-to-peer content distribution service

Ulord, based on blockchain accounting, integrates BitTorrent peer-to-peer content distribution protocol, and adopts efficient software distribution system and peer-to-peer technology for sharing of large volume of files (such as a movie or TV show). Each of users can provide uploading service just like Ulord redistribution of nodes. In the traditional internet, downloading server provides each user issuing the request of downloading with downloading service. The working mode of BitTorrent is different. Holder of distributor or file sends the file to each user, and then it is forwarded by the user to other users; users forward their own files, until downloading of all users is complete. This method can make downloading server handle multiple files of large volume at the same time without occupying a lot of bandwidth.

Distributed hash index service

Ulord uses a distributed hash table (DHT, Distributed Hash Table) to organize the namespace of the user resource. Through the DHT, the relationship mapping (key, value) is realized in network nodes. DHT is a distributed system without center point to provide the key->value query. The mapping information from key to value is stored in many nodes in a distributed manner. Changes of data and node will only affect part of nodes, without an impact on all nodes. As a basic architecture, DHT can be used to build more complex applications, such as distributed file system, domain name service, instant messaging, P2P file sharing and content distribution platform. DHT defines a keyword space, such as bit string set of all 160 digits, then through certain algorithm, the keyword is mapped to all nodes of the whole DHT system. This algorithm is called consistent hashing. Through this algorithm, DHT can find a node according to a keyword and then operate the node, such as storing of data, query of data and so on.

Each node in DHT only needs to be connected with other nodes. A keyword is used to access any node, and the node can transmit information to the node corresponding to the key for processing. This process is called key-based routing. The search engine can get seed file from DHT net node through the character string without relying on seed server. BT download uses the public DHT network, which can greatly reduce the dependence on seed server.

Ulord resource self-purification service

Ulord is a decentralized network without center administrator to review and control content, so it is inevitable that there will be “inappropriate” content resources. Ulord is designed with network voting mode to support user node to initiate proposal, and vote on the content in the net resources. When voting results satisfy certain conditions, it is recognized as “inappropriate” content; the system can make “inappropriate” resources not be accessed by the unlimited increasing of resource charge or making resource offline.

Billing service

In Ulord, communication, storage, release and downloading of resources, in addition to the completion of corresponding application functions, are regarded as a transaction in blockchain. Most transactions in the network contains transaction fees (miner fee), such as publishing and downloading of resource. In Ulord network, users are encouraged to publish and spread high-quality resources. The main billing behavior mainly includes the following categories:

Release resources: when users name the resources, it is required to deposit certain amount of UlordToken; the deposited UlordToken are locked in user account, which cannot be transacted. After the resources are withdrawn, the UlordToken will be returned to the user account after deducting transaction fee. Therefore, Ulord can effectively prevent resources from being maliciously released (Spam);

Download resources: when users take online browsing, and download resources, the corresponding UlordToken in accordance with the set value of resources will be paid;

Resources propagation: when users share resources of other users; when the resource is connected with consumption behavior, benefit from resources spreading can be obtained.

Obtain benefits by providing resources storage: when user upgrades hardware, provide storage and download service as the central node, obtain benefits.

Obtain benefits by providing computing resources: when user node participates in the distributed accounting as miner to obtain benefits from it;

Initiate the proposal: when user initiates the proposal according to network content review, there is a need to pay UlordToken;

System R&D/maintenance: the system will reserve a certain proportion of UlordToken for proposal voting, functional research and development.

Integrated service process

The main process of platform layer service is as follows:

a. User joins Ulord network, and searches a file called “XX comedy film” in the network through the client;

b. Ulord network quickly index hash value on blockchain, and provides the relevant search results;

c. The user pays the corresponding UlordToken according to the paying information of the returned file, and “XX comedy film” file is cached to local place. “XX comedy film” file is not downloaded from cloud or server, but certain one or some nodes in Ulord;

d. In Ulord network, user resources are generally stored in Ulord nodes after being encrypted in blocks, and each block is stored in multiple user nodes or center nodes. Ulord network automatically searches the fastest way to download and recombine resources, so as to ensure that users can download file in the most efficient way;

e. After the user caches the files on his computer, he cannot only watch it, but also share to others;

f. You can also forward the resources in the network, and have the opportunity to get UlordToken.

3.AI service module

In platform layer, we add AI service mode, and the data the mode needs to process comes from two ways:

a. The operation data produced by the application layer, including user behavior data and application behavior data, etc.

b. The operation data of the platform layer and the base layer. Through AI technology, the operation of the underlying system can be more secure, stable and efficient.

The functions supported by AI include three parts: generation management, quality control and distribution effect management.

Generation management

It includes real-time tracking of popular sites and hot content, fast analysis of real-time, authority, influence and attractiveness of contents, information management and behavior analysis of high-quality authors. It attracts excellent content creators to build site by various ways.

Quality control

Original content validation: with block record information of the base layer, the originality of contents is analyzed, so as to prevent malicious imitation, and talking about old topics.

Sensitive information review: in addition to voting review mechanism, the system takes the vulgar content recognition based on AI; through semantic analysis and image detection identification, it controls pornographic and political sensitive topics.

Distribution effect management

Accurate recommendation: the site’s personalized content accurate push is achieved by searching users’ concerns and interests through their visits (browsing page, browsing order, browsing time).

The optimization of transmission path: based on the knowledge map, the propagation path is selected and optimized, the content access through the combination of the related contents is improved, and the user experience is better.

Malicious node analysis: the malicious nodes of “strip wool” in the content communication link are identified and removed to safeguard legitimate rights and interests of real users.

Blockchain team of Hunan Province has rapidly risen, and Tianheguoyun leads the future

With the rapid development of blockchain technology, Chinese cities are layouting blockchain industries. Hangzhou, Chongqing, Hainan, Guangzhou and other cities are building blockchain industrial park. Now Changsha has followed their pace and made great development in blockchain industry.

On August 26, Blockchain Academician Summit Forum & Xingsha Blockchain Industrial Park Project Signing Ceremony with the theme “Xingsha on Blockchain Leads the Future” was held in Changsha Country Garden Phoenix Hotel, hosted by Changsha Economic Development Zone, Changsha County, and Tianheguoyun Co., Ltd., which is the technology provider of Ulord. Several academicians of Chinese Academy of Sciences and Chinese Academy of Engineering, blockchain industry leaders and blockchain entrepreneurs attended the forum to discuss the application of blockchain technology and the development of blockchain industry.

“Blockchain+industry”, policy promotes the development of blockchain in Xingsha

Recently, the book of “Blockchain- to Leaders and Cadres” published by People’s Daily Press is one of the books which was read frequently by Zeng Chaoqun, party secretary of Changsha Economic Development Zone as well as secretary of Changsha County Party Committee. In the summit, Zeng Chaoqun saids that blockchain, as the next generation of cutting-edge technology, is not only a single development of industrial chain and new economic growth point, but also can provide technical support for traditional industrial transformation and upgrading. In intelligent manufacturing and industry 4.0, blockchain technology is introduced in the form of “chain + cloud” to build a distributed intelligent production network, which will greatly enhance the efficiency of the real economy and promote the transformation and upgrading of the manufacturing industry.

Wu Jinming, director of Economic and Technological Committee of Hunan Provincial Political Consultative Conference, said that Changsha has developed blockchain industry with high prospects and solid foundations. Next, the top-level design of the industrial park should be strengthened with more precise directions as a good “locomotive” for Hunan’s new economic development.

Changsha Economic Development Zone and Changsha County has established a blockchain work leading group to grab a new round of technological innovation opportunities. In June this year, Changsha Economic Development Zone Management Committee issued a document of “Changsha Economic Development Zone’s Policy on Supporting the Development of Blockchain Industry (Trial)” (hereinafter referred to as “Policy”). The Policy includes cultivation support, platform support, innovation support, financial support, and talent support for blockchain enterprises (institutions), and clarifies nearly 20 support policies for cash rewards. Meanwhile, the application of academician workstation and the preparatory construction of Xingsha Blockchain Research Institute led by Changsha Economic Development Zone and Changsha County have been launched, and the top-level design for the blockchain industrial park have been made to promote the development and application of blockchain industry in the real economy.

Digital currency≠blockchain, the integration of blockchain and cutting-edge technology leads the future

The rise and shock of cryptocurrencies have made blockchain technology in attention and controversy. However, since 2018, blockchain technology has revealed application potential in more areas. How will this technology develop?

Chen Xiaohong, academician of China Engineering Academy, said that digital currency is not equal to blockchain. Digital currency is only one of the application scenarios of blockchain, and does not necessarily use blockchain technology. Blockchain technology can further promote the transformation of the Internet and represent the second generation of the Internet.

Academician Chen said that blockchain technology needs to be combined with other technologies to maximize the value of blockchain. The blockchain solves the bottleneck of the Internet of Things and provides a cross-subject collaboration foundation. Huawei, Tencent, and Ping An have adopted blockchain technology to build their own smart cities. Blockchain technology has a wide range of application scenarios.

Blockchain technology helps promote the development of AI, expand the application range of AI to various types of data, and AI can help solve the problems of traditional smart contracts in blockchain. AI technology can automate the process of exploiting and repairing vulnerabilities, and utilize flexible rule language, rich scene accumulation and full range of device support to realize intelligent security operation and maintenance to ensure the application deployment of blockchain security.

Blockchain will expand the range of mobile applications, which can be widely used in mobile games, finance and other fields.

Blockchain technology plays a role in the fields of financial insurance, intelligent manufacturing, industrial IOT, etc. Currently, blockchain technology is widely used in finance, environmental protection, food safety, smart cities, etc. The key point of the development of blockchain technology lies in the de-virtualization to accelerate the blockchain application. Relevant technical standards, an international voice should be established and blockchain security issues should be addressed, including breakthroughs in the underlying code, consensus mechanisms, and digital wallet security.

Cultivate talents and reduce regional differences

Zhang Pingwen, academician of Chinese Academy of Sciences, introduced a new generation of information technology promotes social and industrial transformation. Academician Zhang pointed out that technological innovation is very important, which is the foundation of our country. The core of the new generation of information technology are mathematical technology and computer technology, both of which are the support of technological innovation.

Combined with Hunan resources, Academician Zhang provided advice of the perception change for the transformation and upgrading of Changsha County. First, it is very important to create this industrial park and do not lag behind. Second, appreciate talents. Beijing, Shanghai, and Shenzhen have urgent talent needs. How do we compete with others? We should retain talents with career, working treatment and affections. Economic Development Zone and Changsha County must put talent issues first and provide a good environment for talents. Data is the center and talents are fundamental.

How does blockchain empower the real economy in the new economic era?

New technology activates new kinetic energy. Blockchain, a new technology in essential, can be used in many areas. The effect of technology landing depends on the wisdom of the user. If you use it correctly, you can get twice the result with half the effort and provide the inexhaustible momentum for subsequent development. At the summit, Zhang Wenping, academician of Chinese Academy of Sciences, Gui Weihua, academician of Chinese Academy of Engineering, Liao Xiangke, academician of Chinese Academy of Engineering, Chen Xiaohong, academician of Chinese Academy of Engineering…These senior experts and academicians gathered in Xingsha and discussed how blockchain technology serves the real economy in the new situation.

Zhang Pingwen is one of the earliest scholars in China to focus on blockchain technology. He believes that China’s economy is in a period of transition, and that next-generation information technologies such as 5G, Internet of Things, big data, cloud computing, AI, and blockchain are key for the social and industrial transformation. Faced with new technologies and situations, Changsha Economic Development Zone and Changsha County have followed the trend of transformation and upgrading, actively established Xingsha Blockchain Industrial Park, introduced support policies, and absorbed enterprises to settle in, which has already taken the lead in China.

A few years ago, Chen Xiaohong began to pay attention to blockchain technology. At the national sessions of NPC and CPPCC in early 2018, she brought seven proposals, among which blockchain technology is one of her concerns. Chen Xiaohong believes that blockchain has broad application scenarios. For example, in finance, small and medium-sized enterprises often face difficulties in financing and loans, because they are difficult to obtain bank credit. While blockchain technology can not only solve credit problems, but also help banks prevent financial risks. Chen Xiaohong believes that if Changsha Economic Development Zone successfully supports a group of excellent blockchain enterprises, these enterprises will certainly be able to promote the development of information technology in the manufacturing enterprises of the park. Blockchain technology deserves further attention and exploration. After this technology is applied, it will bring huge changes to existing production.

Liao Xiangke, academician of Chinese Academy of Engineering and dean of the School of Computer Science of National University of Defense Technology said blockchain is a data platform for value transfer, which happened in centralized platform before but now can transfer without authoritative public trust institutions.”

Yu Jianing, editorial director of the “White Paper on China’s Blockchain Industry in 2018”, said that the combination of blockchain and real economy will occur in industrial upgrading. Now Tencent and Ping An are already engaged in their own blockchain finance landing. In near future, business information will be on the chain to ensure data validation, data flow, and data security. He also made several suggestions for the development of Xingsha blockchain industrial park. First, it is necessary to recruit those technology-oriented enterprises with real technical strength and respect talents; second, each link implements the idea of blockchain. Take the energy-saving and emission reduction mechanism for example, it should start from the public service, and the industrial policy subsidy fund should be on chain. Since we are determined to engage in blockchain, we must do it well.

Ten blockchain projects are signed in the ceremongy, and

Tianheguoyun leads the future

After the summit forum, the signing ceremony of Xingsha Blockchain Industrial Park Project was held. There were ten companies that signed as the first batch enterprises. Xingsha Times said that Hunan Tianheguoyun Technology Co., Ltd. ranks among the top in terms of blockchain technology in China. Ulord, created by Tianheguoyun, is the first public blockchain in content distribution field in China.

Tan Lin, CEO of Tianheguoyun, was the first signing representative of the enterprises settling in the industrial park. He received the interview from People’s Daily, Hunan Satellite TV and Hunan Jingshi, and said that blockchain technology will get a close tie with the real economy and have more application opportunities to effectively reduce the cost and improve the efficiency of the real economy, as well as promote regional economic development. Changsha, as the economic core of Changsha, Zhuzhou and Xiangtan Cities Group, focuses on the development of emerging industries, which will help promote the effective and rapid development of the entire economic region and grasp the technological opportunities. The birth of any emerging technology will be embraced by the local government to seize the industry’s dividends and create a new city card.

Tianheguoyun is one of the first leading companies in the field of blockchain, and a leading blockchain technology company in China with strong R&D strength. It focuses on blockchain technology and product innovation, accelerates the industrial chain and new economic growth and provides technical support for the transformation and upgrading of traditional industries to enhance the efficiency of the real economy, promote the transformation and upgrading of related industries, and create new business cards for cities.

The rapid development of blockchain technology has accelerated the pace of upgrading of the real economy. The real economy embraces a historic development opportunity, not only in the content field, but also in more areas. And Ulord will also increase the pace of exploration from the content field to other areas of the real economy and create more social value.

Li Honghan, a researcher at the Financial Co-Creation Center of Zhongnan University of Economics and Law commented that Changsha will implement the decision-making deployment of the innovation-driven development strategy more quickly and efficiently, and strengthen the blockchain theory research as well as the innovation of the underlying technology to form a set of blockchain visualization standards and model projects such as Ulord project, create a batch of application templates that can be replicated and promoted, introduce and cultivate a batch of blockchain innovation enterprises, create a professional talent team, and establish a set of management system and operation mechanism. Blockchain team of Hunan Province, represented by Tianheguoyun has rapidly risen, forming a blockchain industry highland, and a blockchain + innovation application base for the whole country.

Architecture of Ulord

The modular design of loose coupling is adopted for Ulord in overall design, which encourages more developers to join in the development of the entire ecosystem. Through web interface, desktop application and mobile APP and other forms of display, the application layer publisher can more easily build site, and publish Internet content distribution service of his own. Architecture of Ulord is as shown in Figure 1, which is composed of Ulord platform and Ulord original chain. Ulord is the P2P data service, including data transmission, data distribution, data storage, data index, accounting model, communication model, Gas model and payment system. The original chain of Ulord is blockchain infrastructure, providing accounting, domain name, master node and other services, so as to ensure that the entire backbone of network is stable and orderly.

Ulord design idea and innovation point

Faced with a huge market prospect, blockchain technology as an effective way to solve the plight of content distribution industry, has drew great attention between technology enthusiasts and investors who have sensitive olfactory. At present, some projects are trying to make use of blockchain to make changes in the information and content industries, but all in an initial stage. There is no mature product or model can bring disruptive changes to the industry.

Design inspirations

Blockchain is the underlying protocol of next-generation Internet, all applications built on which naturally have an almost independent economic system, and the rules of profit distribution in this economy can be clearly defined by smart contract.

Ulord project is proposed and developed, which is mainly from the following three aspects:

a. The characteristics of blockchain technology can effectively solve the problems of content distribution industry. The copyright confirmation and content distribution are united, and the content publishing mode of the current entertainment and publishing industry is changed and re-defined. After decentralization, only two of the most basic roles exist for the content distribution industry: the creator (Producer) and the user (User), in this case, efficient and reasonable distribution of interests will be made. There is an urgent need to solve the technical difficulties and the mechanism innovation in the content distribution.

b. Blockchain is at the primary stage of development, and there are a lot of public blockchains. Consequently a wide variety of applications appears, but the public blockchain to effectively support the content distribution has not yet appeared, which cannot bear rich website service type in content. Especially in data storage, data quality of service and content payment model, there are many problems. It needs blockchain platform to solve the pain points of content distribution industry;

c. From blockchain itself, the existing blockchain technology has many urgent problems and bottlenecks, such as internet congestion, delayed payment, obvious mining centralization trend, high resource consumption, and some public blockchains with security vulnerabilities, which is difficult to meet the practical application requirements. So there is an urgent need to take further research and practice to solve the above problems in the blockchain underlying technology, promoting the fast blockchain application and development.

Ulord is a distributed P2P internet open source project based on blockchain technology. Different from our daily access to the internet server, there is no concept of server in Ulord, all internet data are scattered in various Ulord user's computers, and people only need a pair of asymmetric key to publish their own site. Everyone can find the site service announced by the publisher through the search and domain name, and directly download the site data in P2P net. After more and more people’s visit, the publisher's site will be stored by many computers. Those computers with access to your website will start to make the seed for your site, just like the BT seed, and the content of your site will continue to exist in numerous computers. In Ulord, in order to provide a better user experience, two kinds of role node are used for storage of data, and one is the master node role. The user of this role stores the data on Ulord through providing storage service with high QoS, at the same time, earns the income according to the provided storage space; the other is the common user computer role, which can only backup the user's favorite resources as a supplement to the master node role. When the users get access to the site service, through the distributed hash table (DHT, Distributed Hash Table) technology, it allows users to quickly download the required data segment from the P2P net, and then it is assembled by the client to restore the complete data. Due to the technology of P2P for bearing, Ulord resources have high availability without downtime.

Innovation point

From design, we will isolate the system into two levels, the bottom “operating system” and the upper layer “application program”. The infrastructure of transparent and open ledger and smart contract that cannot be tampered is established at the bottom, and the upper application program is used for completing the business logic without considering how to develop the decentralization application.

For the original chain of supporting content publishing platform is concerned, we will carry out some original work based on this application scenario, including:

1.The master node system is introduced to solve the problem of long communication delay, and small storage space

The new mechanism is designed to encourage users and investors to participate in the master node Ulord construction, and provide stable QoS data storage service; it provides a variety of cross-platform solutions, which is convenient for the users to master node deployment service, including Linux/Windows/OSX and other mainstream operating systems; through the master node service, it can support more than 4000 of the trading frequency per second to better meet the practical application.

2.The voting mechanism is established to promote community development and content review

It allows each user on the Ulord to vote for the Ulord resources, the site and the suggestions for the improvement to achieve two goals: one is to assess the plan proposed by the developers to promote the community contribution to Ulord; the two is to review the resources and sites on Ulord to maintain ecological, healthy and orderly development of Ulord.

3.Reasonable income distribution mechanism is set to stimulate the majority of developers to contribute

10% of revenue is set aside to the entire community's developers, and fund the developers to perform meaningful development plan. The evaluation mechanism of code review and task quality evaluation are introduced to supervise the funded projects to be completed as required on time, form a virtuous circle, and promote the ecological and healthy development of Ulord.

4.InterPlanetary Domain Name System is established to provide a unique，    simple and readable domain name service

The blockchain resources are usually represented with the address of 34 character strings in length, which is not easy to remember, nor convenient to use. In Ulord design, through the establishment of the InterPlanetary Domain Name System (IPDNS), it provides decentralized domain name analysis service for the users. Example: Ulord user releases resources, and there is no domain name resolution, through r/https://ulord.one/U45c21eP5QGefi2DMPTfTL5SLmv7DivfNa access. After he applies for a domain name service, he can directly access it through uld://ulord.one/Alice, where Ulord is the requested custom domain name, and U45c21eP5QGefi2DMPTfTL5SLmv7DivfNa is the resource address.

5.The sidechain technology is introduced to achieve rapid deployment of smart contract

The sidechain technology can be used to achieve being compatible with Ethernet virtual machine, and release of smart contract. Any user building the site in Ulord through the friendly API, providing Internet content distribution service, can customize their tokens, and operate their own site by tokens. Tokens can be converted to a certain proportion with UlordToken.

l The mixed consensus mechanism of PoW + PoS is used to attract more idle resources to join Ulord

In order to better load application on the Ulord platform, the design implements a hybrid consensus mechanism: PoW (Proof of Work) and PoS (Proof of Storage).PoW algorithm is used for accounting with a new CPU mining algorithm CryptoHello which can effectively resist all kinds of known and unknown attack through the AES algorithm and the improved algorithm; PoS algorithm is suitable for the construction of IPFS infrastructure, and encourages more users to provide large storage space for storage of data on the Ulord platform.

The main innovations of the Ulord's platform layer and application layer include:

6.A distributed file storage, retrieval and distribution mechanism based on blockchain are designed and implemented

Based on the bottom blockchain, integrate the P2P downloading, distributed file organization and intelligent learning module, provide quick content search service, content distributed storage service, customized service of node, peer-to-peer content distribution service, distributed hash indexing service and cyber source self-purification service.

7.An efficient communication model of value

It establishes the value transmission chain of content distribution process, encourages users to participate actively through profit distribution mechanism, so that the users are willing to contribute valuable contents and efficiently perform excellent content dissemination.

8.It supports intelligent push of contents based on the AI algorithm

a)According to the data of high dimension, mixed type and strong timeliness, a multi-source knowledge extraction and association method based on deep neural net is designed, which realizes entity name recognition, entity attribute extraction method for the site, content and author and other essential information;

b) Through the hybrid model method, collaborative recommendation method based on knowledge embedding and recommended method based on online real-time feedback, we achieve intelligent push of content for different users and different dimensions;

c) Through hybrid recommended method based on domain knowledge, and with the integrated knowledge structure feature, topic feature and semantic features of content vector space modeling technology, the mixed recommendation of the recommended method based on content and collaborative recommendation method can be achieved.

9.Content control and promotion of communication based on AI algorithm

a. Through the integrated knowledge structure feature, topic feature and semantic features of content vector space modeling technology, the sensitive information can be examined automatically.

b. The communication path based on the knowledge map is selected and optimized; through the recombination of related contents, content access and the user experience are improved.

The innovative design of these technological routes and ecosystems provides strong support for Ulord, and tries to innovate the current status of content distribution industry and promote its healthy development.

Terminology interpretation:

Fork: In blockchain, miners mine out blocks and link it to the main chain. Generally, only one block is generated at the same time. If two blocks are generated at the same time, there will be two blockchains of the same length and the same transaction information in the block but different miners’ signatures or different transaction ordering. This situation is called fork.

Ulord master node: the comprehensive interpretation of election

Preview

Recently, the master node election has attracted much attention from blockchain industry. What is Ulord master node? What are their functions? How do they work together? This article leads you to know more about Ulord master nodes.

Brief introduction of Master node

The original idea of Ulord master nodes should come from full nodes of Bitcoin. As we all know, blockchain is a distributed ledger, which means that transfer information in bitcoin system is completely stored on many distributed computer nodes. If a node wants to verify that a transaction is legal, it needs to find out if the source of the transaction has not been spent on the distributed ledger. In this condition, it has two options. One is to save a complete ledger data locally. The other is verified by other nodes that have saved the complete ledger data. Since the Bitcoin system does not motivate the nodes that hold complete blockchain datas, as the database becomes larger and larger over time, the maintenance cost is gradually increased, resulting in the gradual reduction of the entire nodes of the Bitcoin system. System data synchronization time is prolonged, and even affects system performance. In addition, there are some unstable factors in the whole node itself. In the case of a small number of nodes, the failure of such a single node even affects functions of the entire system.

Based on the above considerations, Dash system introduces the concept of “master node”. In Dash system, nodes with 1000 dash can be upgraded to be master node. If it can remain online for a period of time, it will get rewards, which solves the problem of the node number reducing. On the basis of Dash, Ulord has made more explorations and the following innovations:

1. Introduce the master node candidate mechanism

To encourage users to join master nodes, Ulord distributes part of the revenue of the entire network to master node holders. At the same time, it introduces service quality assessment mechanism and adopts the principle of survival of the fittest to ensure that master node users must continuously invest in and maintain master nodes to work well.

2. Diversified master node service

In Ulord system, the services provided by master nodes are diversified, which can diversify system functions, such as distributed storage, distributed computing, instant payment, specific server deployment, higher-level accounting services, voting and promotion services, etc. Therefore, in the Ulord system, the functions of master nodes are diversified, and participants can select the type of master nodes according to their actual situation and determine the way to participate in Ulord ecosystem.

3. Low threshold of master node

To attract more users to participate in the building of master nodes, Ulord system will develop cross-platform master node client software, such as Linux, to reduce the participation threshold of the master node system and enhance user experience of master node holders.

In short, in Ulord system, master node system forms a backbone network to guarantee communication and real-time verification of transactions, and constructs a massive distributed resource pool to satisfy the content distribution mechanism, ensure high-quality network storage, and provide better data flowing service. If Ulord system is a super distributed computing cluster, each master node is a smallest functional unit in it.

Types of master nodes

According to the overall design of Ulord system, master node system plays an important role from “management and technology” in the whole system. To complete Ulord’s grand vision, the functions of master nodes will be diversified, and various types of master nodes will exist at the same time to accomplish various complex tasks in the content distribution process. According to main services provided by the master nodes, the servers can be divided into five categories, as described below:

1. Application master server. It is mainly responsible for carrying Ulord public blockchain wallet, block browser, DNS resolution and gateway services;

2. Storage master server. It mainly deploys UDFS services and provides distributed storage services. This is the most basic type of master nodes mentioned in the white paper;

3. Computing master server. It focuses on providing distributed computing services, including deep learning, big data processing, high-performance computing, etc;

4. Basic service server. It provides the most basic full-node service, and it is the honorary master nodes. It conducts promotion for Ulord community, such as resource docking and project promotion to expand the influence of Ulord;

5. Consensus server. It provides super account service and high-throughput blockchain server.

The first batch of master node number is 500, mainly application and basic type, which is based on the scientific decision made in the initial stage of system development. In the early stage, Ulord pays attention to its promotion, so it focuses on basic master nodes. In middle and later period, other master nodes will gradually increase, which can avoid the waste of resources in the early stage and satisfy the service demand of the later stage to ensure the healthy and stable development of the system. It is worth noting that with the gradual development of Ulord system, the configuration requirements for various master nodes will be adjusted according to actual needs to meet the ever-increasing service quality requirements.

Rights and obligations of master node

1. Master node rights

Rights of master nodes are mainly reflected revenue incentives of the system. In Ulord system, the revenue source of master nodes is mainly based on the underlying UTs’ incentives, accounting for about 30% of the total UTs. The specific incentives are as follows.

From the above table, the reward for the system to give master nodes is very rich! Especially in the early stage, the number of master nodes is small, and dividends of participants are obvious. Although the system considers this problem in rewards, the early participants still have more advantages. Some people may think that this is not fair enough, but from another perspective, it really reflects the fairness that Ulord has always advocated. The early participants are very valuable and important. The early support from a small number of volunteers with the full faith of Ulord pushes Ulord development, and finally gets a win-win situation.

In the long run, the revenue source for master nodes will be based on the various services it provides. Ulord is committed to building an application support platform based on blockchain technology, providing blockchain services for distributed applications such as distributed storage and computing. As the original provider of various services in Ulord system, it is reasonable that the master node gets some incentives in the content distribution process. After all, there is no free lunch in the world. From this perspective, the relationship between master nodes and miners is also very clear. Miners provide the basic bookkeeping services to provide security for stable operation of the entire system, while master nodes promote Ulord ecosystem by providing a full range of services, both of which promote the value of Ulord, and complement each other.

2. Obligations of master node

From the above revenues, master nodes in Ulord system benefit a lot, which means that it needs to provide a higher basic service to ensure that the system functions are stable and efficient. The obligations mentioned here can be strictly defined in two categories. One is the obligation to be fulfilled by the master node server, which is explained above; the other is the obligation of master node holders, which will be described in detail.

Master node holders mainly fulfill two obligations: on the one hand, it is the obligation to Ulord system, which consists of two main tasks. First, resources and sites in Ulord system are reviewed to maintain the healthy and orderly development of Ulord. For content distribution, the compliance of contents itself is very important. In Ulord system, there are two steps to check the compliance. The first step is set in the system’s AI module, which conducts a preliminary review of contents. And the second step is just set in master nodes. Second, master nodes evaluate proposals from developers to promote the community’s contribution to Ulord. The proposal is a unified entry for developers around the world to participate in Ulord to improve it. When a developer team submits a proposal, one of the master nodes’ work is to evaluate it. Since Ulord is a decentralized system, the fulfillment of both obligations is done by voting.

On the other hand, it is the responsibility of master node holders to Ulord project, including some promotion activities of Ulord project, such as offline sharing, community building, online activities, and propaganda. The design of the incentive mechanism of master node system fully reflects the philosophy that everyone participates and everyone benefits. If you agree with the value of Ulord project and support its development, you may become master node holder. With the fair elimination mechanism and rotation mechanism, there is a balance between fairness and efficiency. It doesn’t matter that if you do not have enough resources but with full of passion. Participating in online and offline activities of Ulord helps you become master node.

Basic requirements of master nodes

Maybe some reader have the willingness to be master nodes. Can everyone become master node and get the corresponding benefits? The answer is no. Through comprehensive consideration and careful design, the total number of master nodes is limited to 10,000 or less, and each ordinary node needs to meet some basic conditions to become the master node.

1. Lock 10000 UTs

Some friends may not understand this requirement and feel that the threshold is too high, or invest too much. In fact, this requirement is reasonable. First, it is helpful to stabilize UT value in the early stage of the project. During the first four years, 100 million UTs based on 10000 master nodes will be locked; second, in Token mode, users with more UTs are essentially equivalent to “large shareholders”. The appreciation of UTs has direct positive incentives for these users, so they will also participate in various promotion activities for UT to help the development of Ulord.

2. Promote Ulord and increase the impact of Ulord project

It is consistent with the first point. On the one hand, if you want to get the incentive of PoS, that is to say, master node holders get revenues and they must fulfill some obligations to promote Ulord project; On the other hand, if participants want to benefit more from the same UT incentives, they can hold promotion activities to strengthen UT’s consensus.

3. Basic requirements for some hardware and software

After satisfying some of the above conditions, master node holder needs to provide distributed resources for the entire Ulord system. According to the classification of master nodes and the different periods of development of Ulord system, the requirements of various master nodes will be different. The specific requirements need to refer to the latest master node election rules.

Summary

The above four parts gave a comprehensive introduction to Ulord master node system. If you want to know more information and get the latest news, you can follow us to know more. Ulord master node system plays a crucial role in Ulord system. It is very meaningful to participate in the master node construction.
