  Acute  Angle  Cloud   Acute  Angle  Cloud  Overview   Acute Angle Cloud is a globally distributed IaaS platform. It is designed to be a globally distributed cloud computing service with a basic-layer platform based on the New PC Network (distributed hardware terminals), the Acute Angle Chain and CAN (Content-Addressable Network). Its construction will be achieved though the Acute Angle Chain, Acute Angle Cloud 1.0 and Acute Angle Cloud 2.0. 1.1: Figure: Overview of Acute Angle Cloud History  of  the  Internet   On October 29, 1969, the first node of the University of California - Los Angeles (UCLA) was connected to the second node of the Stanford Research Institute (SRI) on the ARPANET, marking the inception of the Internet era. Looking back at the Internet’s history, from the very beginning to its current high-speed development, we can divide it, roughly, into three stages: Web1.0 Internet, Web2.0 mobile Internet and Web3.0 interplanetary Internet. The Web1.0 Internet began in the 1990s when the Internet was initially opened to the public. At that point, the technology needed for uploading information was incredibly expensive and had to be operated by professionals. Therefore, a large amount of online information was released and consumed by media firms, commercial institutions, schools and authorities. A vast reduction in cost and impressive increase in technological advancement has led to our current reality - almost every Internet user can upload information in various forms of content. Such a change has introduced the concept of Web2.0; mobile Internet. The Web2.0; mobile Internet is mainly manifested by users' participation or social interaction, the blog space, community websites, peer-to-peer tools, etc. While developing the Web2.0, the founder of the world wide web network, Tim Berners-Lee (along with other computer scientists) began to conceptualize Web3.0; interplanetary Internet. The original intention of Web3.0; interplanetary Internet was to facilitate communication using devices as terminals, rather than to communicate and aggregate information on the Internet, thus achieving "decentralization". Due to the development of the Internet and further progress in telecommunication, people can talk to almost anyone, from anywhere in the world.  

  Blockchain,  A  New  Trend   On October 31st, 2008, Satoshi Nakamoto published the Bitcoin white paper – “A Peer-to-Peer Electronic Cash System”, declaring the inception of the value transmission network. Bitcoin has many creditable designs such as data backup, relative anonymity of those involved, and, most importantly, a new system that eradicated the need for trusted third parties. However, its own transaction performance and Proof of Work (POW) consensus mechanism gradually revealed some problems. The underlying technology of Bitcoin is known as the blockchain. In recent years, people have innovated mainly concerning transaction performance, consensus algorithms and safe anonymity of the blockchain, such as promotion of transaction performance by graphene and the lightning network; enrichment and improvement of consensus algorithm by Proof of Stake (POS), Delegated Proof of Stake (DPOS), and Practical Byzantine Fault Tolerance (PBFT); improvement of transaction safety by Zero-Knowledge Proof (ZKP) and mixing. As a promising blockchain ecosystem, Acute Angle Cloud perfectly combines the strengths of Ethereum and BitShares and solves inherent defects of the existing blockchain system. Acute Angle Cloud is expected to gradually form a blockchain economy, promote industrial efficiency and boost efficient and synergetic development of society. It plans to accomplish this by the setup of a basic platform, exploitation of various products, and through the development and iteration of commercialized and implemented projects. Acute Angle Cloud defines a new blockchain economy. Acute  Angle  Cloud  Relevance   1.   Prevention of resource waste Through virtual machines, the Acute Angle Cloud solves the issue of unused hard disk and CPU resources in the personal computer (PC). It can aggregate and allocate the users' idle hard disk and CPU resources with full cyclic use, forming an integrated application in a chain ecosystem. 2.   Storage potential Through distributed storage technology, the issue of storage waste is solved. Data can be automatically re-distributed, enhancing the utilization rate of storage space and connecting all the computing devices with the same file system. The principle behind it is to replace address-based content with domain name content. In other words, users can find content saved in a location instead of an address and the hash of the content is verified instead of the identity of the content creator. It will enable webpage browsing to be faster, safer and more robust. 3.   Cost Reduction Through blockchain technology, cloud computing, and CAN technology, the Acute Angle Cloud creates a distributed IaaS platform. It dramatically cuts the high operational and maintenance costs of traditional centralized server rooms and reasonably utilizes idle resources and shares the returns with its users. Strengths: low user cost, globalization, durable storage and high stability Acute Angle Cloud can be used as: •   A virtual machine’s root file system •   A server •   A database •   A (cryptographic) communication platform  

  •   Any type of CDN •   A long-lasting Web Acute  Angle  Cloud  Development  plan   Centralized  Cloud  Computing  Service  Model  Overview   The structure of the cloud system has gained popularity in recent years, and it has unique advantages compared with conventional and locally deployed IT modes. The cloud service has won the favor of enterprises because of its many benefits, such as round-the-clock supported access, resource sharing, self-service, instant use on demand, pay-as-you-go, and can meet enterprises' needs of use in a flexible way so as to reduce the cost of use. As estimated by Gartner, an international research and advisory body, the global, public cloud services market has massive scalability, reaching US$209.2 billion in 2016. The figure is expected to hit US$246.8 billion in 2017 and exceed US$383.3 billion in 2020. 4.1:Global Cloud Service Market Scale Even though cloud computing models are constantly evolving, the industry is currently divided into three major categories: IaaS, PaaS, and SaaS. The infrastructure is the first tier, the platform is the second tier, and software is the third tier, namely: •   IaaS (Infrastructure-as-a-Service) •   PaaS (Platform-as-a-Service) •   SaaS (Software-as-a-Service) With the progression of the era we live in, cloud computing is no longer an option, but a requirement for enterprise development. To borrow a statement from Gartner, "Cloud is not a strategy, it is a tactic." (Cloud computing is no longer a strategic issue. It is a tactical issue.)  

  Acute  Angle  Cloud  based  on  the  IaaS  Service  Model     There are still two main problems associated with the current centralized cloud computing model: (1) Users do not own their own data; (2) Remote servers are susceptible to security breaches. Blockchain technology is separate to the centralized cloud computing model, and allows it to become decentralized. Bitcoin and other decentralized systems explicitly return digital assets to end-users, eliminating the need for a third-party server, or for trust in the infrastructure. IaaS, as the name implies, enables consumers to access services from a well-developed computer infrastructure over the Internet. 2016 Cloud Service Market Shares 4.2: Cloud Service Market Shares in 2016 The value of IaaS services in 2016 reached US$25.2 billion, with a growth rate of 56%, far more than 18% for the cloud service and 20% for SaaS. It's expected to maintain its rapid growth, with a compound annual growth rate of 29% expected by 2021. The development of IaaS infrastructure is relatively advanced, and the rapid distribution after its announcement has reached a considerable market size. Acute  Angle  Cloud  vs.  traditional  IaaS  platform     The basic hardware of a computer is simple; It consists of computing components and storage components. The working process of the computer is just as conceptually basic; draw data from the storage component into the calculation component and compute. After the results are obtained, the output goes to the display and other devices and thus a cycle of work tasks is completed. The deployment of hardware terminals as global nodes is assisting the Acute Angle Cloud to gradually complete the transition from cloud to fog computing.  

  Fog computing is a paravirtualization frame model of service computing between cloud computing and personal computing. Fog computing focuses on small clouds such as Personal Clouds, Private Clouds and Enterprise Clouds, which operate differently from general cloud computing. Fog computing focuses on quantity which aids in its success, and every computing node plays a role, regardless of how weak its capacity is. Fog computing has several major features: low latency and location awareness, broader geographical distribution, applications suitable for mobility, and support for more fringe nodes. These features make deployment of mobile services more convenient, which can satisfy a broader connection of nodes. Cloud computing is a computing model which takes advantage of the Internet to use resources (such as storage devices of shared computing facilities and applications) anywhere at any time, conveniently and efficiently. Cloud computing consists of four basic parts: Cloud Platform, Cloud Storage, Cloud Terminal and Cloud Security. From the user's standpoint, it can be divided into Public Cloud, Private Cloud, Hybrid Cloud etc. From the service viewpoint, it can be divided into Infrastructure as a service (IaaS), Platform as a service (PaaS) and Software as a service (SaaS). The main problems associated with the cloud computing industry are as follows: 1.   Computing needs increase exponentially, and the cost of bandwidth remains high, leading to an increase of relevant operating costs. This becomes an obstacle for the development of a global industrial chain. 2.   The cost of traditional CDN, self-built nodes is high and the node implementation is slow, which negatively effects users as computing needs increase. 3.   Traditional cloud model's utilization of broadband is insufficient, resulting in a large number of wasted resources, which is also the main reason for the conflict between computing needs and computing power. Fog computing adds a layer between the terminal and the data center, known as the network edge layer. It's like adding another small server or router with a memory, that can process and save data without having to put it into the "Cloud" directly. This reduces stress on the Cloud and improves efficiency and transmission rates, while simultaneously reducing time delay. Compared with cloud computing, the framework adopted by fog computing is more distributed, and closer to the edge of the network. Fog computing concentrates information, data processing and data application on the devices at the edge of the network, rather than saving almost most of the info onto the cloud (as cloud computing does). The storage and processing of the data is more dependent on the local device, rather than the server. Therefore, cloud computing can be referred to as the new generation of centralized computing, whereas fog computing is the new generation of distributed computing which corresponds to the feature of "internet decentralization" and solves the problem that the cloud computing market currently faces. With P2SP technology, Acute Angle Cloud can provide shared computing services to the enterprises. The Acute Angle Cloud will incorporate blockchain technology to build a fair and transparent incentive mechanism, compelling members of the public to participate in the sharing and exchange of the data resources. Opening the shared computing services of the Acute Angle Cloud to individual users comprehensively makes each common user a resourceful node of the decentralized shared computing system, allowing them to benefit from it. Due to the cloud service’s beneficial features such as low cost, instant access, etc., the rapidly growing O2O, E-business, and social networking (to name a but a few) lead the way in realizing the benefits of transferring from the traditional self-built servers to cloud servers. Many surveys have shown an increase in the industries using cloud services. Cloud services are still at an early stage, but the settlement in security will result in more sectors migrating to the cloud. This crossover is expected to cover government administration, healthcare, finance, industry and other sectors in the next five years.  

  4.4:Cloud Service Usage Trend for Different Industries According to a Global IaaS report issued by Gartner, Amazon AWS, Microsoft Azure and Alibaba Cloud are the top three cloud services in the world, with a market share of 44.2%, 7.1% and 3% respectively. Amazon takes a dominating position, but Alibaba is the fastest growing The three major cloud service providers are actively developing their ecosystems. Amazon AWS is joining forces with other mainstream IT producers while Microsoft Azure is also supported on the OS Linux. Alibaba Cloud is taking advantage of the ecosystem which has already been built by Alibaba, potentially allowing a more seamless transition and user experience. Ecosystems have been a major force driving the growth of IaaS cloud services. Competition Analysis: 1.   The cloud services that are directly serving individual users remain immature. The Acute Angle Cloud allows everyone to be at a crucial point of the distributed cloud network and builds an ecosystem based on the users, giving it both a competitive edge and commercial value. 2.   The concern for security and privacy is still the greatest resistance for the adoption of a public chain. However, blockchain and CAN technology can solve the issues of data storage and user privacy. 3.   The cost for centralized, physical storage can be reduced, but the cost in manpower, operations and maintenance remain difficult to curtail. In contrast, the distributed cloud storage does not need centralized servers, making the cost significantly lower. 4.   The centralized servers can ensure data security, but not as well as CAN, which is capable of further reducing the system's redundancy, and ensures that the files are more secure through blockchain technology.  

  Acute  Angle  Cloud  v1.0   Overview   The Acute Angle Cloud, v1.0, is based on the New PC Network (as the storage nodes) and the CAN peer-to-peer hypermedia distributed protocol to create a globally distributed file storage system. 1.   Operational principle of the Acute Angle Cloud v1.0 •   Each file and its block are given a unique “fingerprint”, called an encrypted hash. •   CAN deletes the files with the same hash value throughout the network, judges which files are redundant, and also traces the version history of each file. •   Each node stores the content that they want and the relevant index information, which helps locate the source. •   Files can easily be located using their hash value. •   Using IPNS (decentralized naming system), each file can be named with a readable name, instead of the hash, making it easy to find. What CAN envisions, is not only to turn all the network terminal nodes into a Browser or Client, but also to make anyone the operator of the network and storage server. 2.   Characteristics of the Acute Angle Cloud 1.0 •   The Acute Angle Cloud is based on content addresses, not the domain name address. Each file (content) is unique; one file connected to the CAN network would be given the only encrypted hash value based on its computing content. This would change our habit of utilizing domain names to access the network. •   Supplies a "history version controller" (such as git) of the file, and stores the different versions of the stored file to multiple nodes. •   The Acute Angle Chain operating on the CAN network is just the hash value table used for storing the internet files. The content (file) address on the link will be queried while accessing the network every time it is necessary. •   Uses the ecosystem’s reward distribution to encourage the user to contribute more shared space for storing data. The users obtain the ecosystem’s rewards by providing available disk space, processing power and bandwidth to the network. The users can exchange the rewards for storage space and other services within the ecosystem. •   The Acute Angle Cloud’s reward system allows a lower cost of data storage to the user, and the storage network is made more stable by setting online time goals to motivate users to stay online. •   The Acute Angle Cloud v1.0 helps build a freer and more independent network.  

  Phased  upgrading  of  the  Acute  Angle  Cloud,  v2.0   1.  Problems  solved  by  the  Acute  Angle  Cloud,  v2.0   Acute Angle Cloud, v2.0 is committed to adopting a reward mechanism, through the establishment of a New PC Network, to distribute the Acute Angle Cloud’s nodes worldwide and create a unified IaaS service. This aims to realize economic globalization of the distributed cloud storage, as well as providing server services, CDN accelerated services, file storage services and database services for individuals or SMEs at a low storage price. 2.  Operational  principle  of  the  Acute  Angle  Cloud,  v2.0   To create a globally distributed IaaS service platform through networking, virtualization, operating systems, a New PC Network, OpenStack and the Acute Angle Cloud, v1.0. •   Computing: A set of controllers will be used in the management of the virtual machines for the life cycle of a single user or group, and will supply virtual services according to users' needs. They are responsible for the operation of the virtual machine including set up, startup, shutdown, standby, stop, adjust, remove, restart, destroy, and configuring CPU, internal memory and other information specifications. •   Object Storage: Swift refers to the system that creates object storage on a large scale of extensible systems through built-in redundancy and high error tolerance mechanisms, allowing for storing or retrieving files. It can provide image storage for the Glance, and volume backup service for the Cinder. •   Persistent Object Storage: The Acute Angle Cloud, v1.0 could incorporate object storage with the advantages of high error tolerance, higher security etc. on content-addressable and peer-to-peer hypermedia protocols. It also provides image memory for the Glance, and volume backup service for Cinder. •   Image Service: The search and retrieval system of virtual machine imagery supports multiple virtual machine image formats (AKI, AMI, ARI, ISO, QCOW2, Raw, VDI, VHD, VMDK). Uploading, deleting and editing the images basic information will be supported. •   Identity Service Keystone. with the functions of providing identity verification, service regulations and service tickets for other services of OpenStack, manages Domains, Projects, Users, Groups and Roles. •   Network & Address Management: Supply network virtualization technology for cloud computing, and providing network connection services for other OpenStack services. The technology will supply the users with an interface, and will define: Network, Subnet and Router, configure DHCP, DNS, LB, L3 service, and the network supports GRE and VLAN. Plug-in architecture supports many mainstream network manufacturers and technologies, such as Open vSwitch.  

  •   Block Storage: Provide a stable data block storage service for the cloud, and its plug-in driver architecture is available for the set up and management of block devices, such as set up volume, delete volume, on- hook and unload volume on the case. •   Lasting Block Storage Acute Angle Cloud v1.0 provides stable and persistent data block storage services on the cloud when it is running •   UI Dashboard A web management portal is used to simplify the service operations for the user, such as start- up, distribute IP addresses, configure access control, etc. •   Metering Filters almost everything that happens inside the Acute Angle Cloud v2.0, and provides data support for billing and monitoring, as well as other services. •   Orchestration A collaborative deployment method defined by a module is provided to achieve automatic deployment under the operation environment of cloud infrastructure software (computing, storage and network resources). •   Database service It provides extensible and reliable, relational and non-relational database engine services for users of the Acute Angle Cloud v2.0. Acute  Angle  Cloud  Global  Node  Distribution  Strategy   Super  Network  Plan  Overview     In order to speed up the deployment of the Acute Angle Cloud’s global resource nodes and improve the efficiency of point-to-point, end-to-end data transmission on the chain, the Super Network project emerged as a stand-alone application. It's based on the Acute Angle Chain and developed in the Acute Angle client, dedicated to serving the world. Blockchain believers and enthusiasts can invite more users to easily join in. Both new and existing users can concurrently build a blockchain-node network architecture that covers a wider area and more densely-distributed network, finally realizing a self-healing cloud computing storage network. In addition, in order to reach a consensus with the Acute Angle Cloud early adopters, we conducted a user survey (110 samples), before the Super Network plan was officially launched. The following are some of the findings:  

  Do you support the creation of the Super Network? A: Heavily Support B: Support C: Do not support D: Indifferent What do you believe SN’s purpose to be? A: Necessary for accelerating the deployment of global nodes, making the ecosystem more powerful and stable B: Necessary, but there needs to be a balance between it and the Acute Angle Series C: I am against having SN D: Indifferent The more point-to-point nodes there are in the network, the faster the data transmission will be. The Super Network plans to serve blockchain enthusiasts around the world with its low threshold, high participation, and easy-to-use interface. Super Network plans to follow the open, transparent, and tamper-proof features associated with blockchain technology, allowing more users to easily get involved. The SN (ecosystem’s generic Token) reward is distributed to the resource contributors through an additional incentive mechanism that can be used within the cloud’s ecosystem. The Super Network plan will inspire more users to enter the blockchain world. The Acute Angle series hardware products (along other PC equipment) will serve as New PC Network devices and jointly serve as resource nodes in the Acute Angle Cloud ecosystem. Users with other PC devices, can not only participate in the construction of the Acute Angle Cloud’s ecosystem easily and receive the SN Token reward, but will also receive AAC rewards (10% of the total amount of AAC, coming out of the Acute Angle Foundation reserve). This will help Acute Angle Cloud build a blockchain network architecture with nodes that cover a wider geographical area and larger distances. It will also lay the foundation for the integration of the resources gathered by the Acute Angle Cloud, into a cloud computing storage network that anyone in the world can rely on. New  PC  Network  Overview     The New PC Network is made up of global PC devices that make up the Super Network. To help collect a large amount of idle resources from computing devices, we will build a complete Acute Angle Cloud ecosystem and provide users with safer and more convenient data storage services. The New PC Network is open to all users who have PC devices but are not fully utilizing the hardware and computing resources in them, they can share these idle resources and get rewards in return. Users can activate the Super Network by installing the Acute Angle client and exchanging AAC for a certain amount of SN to purchase an activation code. The activation is bound to that single device, and the device becomes a node registered on the Acute Angle Chain. The New PC Network devices join the Acute Angle Cloud’s global node layout strategy in exchange for rewards. Thus, a complete blockchain, full-node network is created by linking blockchain users, assets, applications, etc., and the Acute Angle Cloud’s global node coverage is expanded, while accelerating the point-to- point data transmission efficiency. We call on more users around the world to use their PC devices, join the Super Network program and share the “dividends” brought about by blockchain technology innovation. After the Super  

  Network application is successfully activated, the user can select the devices’ idle disk, test the network environment, as well as other operations to complete resource sharing and become a new node registered on the Acute Angle Chain. The joint construction of the Acute Angle Cloud’s ecosystem is rewarded with token rewards. New  PC  Network  Advantages     •   Uses idle computer resources •   Low operating threshold •   Blockchain attributes •   Computes resource sharing •   Safe and transparent •   Token reward distribution Acute  Angle  Chain   Overview   The Acute Angle Chain is a decentralized public blockchain platform, used by developers to quickly, easily and safely distribute tokens, smart contracts and blockchain systems. The Acute Angle Chain is committed to building a blockchain network system of global information, which values interconnection and trust exchange. The philosophy and technological mission of the Acute Angle Chain is to build an unobstructed blockchain world. Background  and  Importance   Blockchain is a decentralized network capable of achieving peer-to-peer value exchange, which is referred to as value Internet. Helped by Acute Angle Chain, we can create a decentralized and value-driven world of mutual cooperation and peer-to-peer exchange where an individual is directly connected to another as part of a community or society. First, we build a safe and stable modular blockchain network allowing us to use smart contracts and digital assets. At this stage, we introduce the Acute Angle PC - a hardware capable of intelligently testing, monitoring and running a suitable environment. The Acute Angle PC can ensure that contracts running in the Acute Angle Chain are safe, thus preventing events such as DAO. The Acute Angle Cloud can meet different industries’ storage needs, including insurance companies, electronic files, digital currency, trace origin, and personal credit record. The blockchain network is constantly evolving, easy to use, low cost and susceptible to customization. With the Acute Angle Chain, we connect user information and might even get through to other networks (possibly non-blockchain) for data interaction, thus building a cyberspace of multidimensional data correlation. Through multidimensional data such as personal credit, assets, production and consumption data, we can better integrate community consensus, individual behavior and value exchange. Carrying value in the ecosystem, the digital currency issued by the Acute Angle Chain and named after it as AAC. Using the AAC can allow us to share CDN services, idle hard disk resources, original resources and other basic blockchain services.  

  Design  Philosophy   The Acute Angle Chain puts stability, security, scalability and ease of use among its design priorities. By introducing modular virtual machines, value exchanges, and bifurcation mechanisms, we create a blockchain network that is easy to use, low-cost, and moderately customizable. In theory, the Acute Angle Chain can achieve 1,000 TPS of available performance by optimizing the block intervals, block capacity, and consensus algorithm. The New PC Network, which is one of the core parts of the Acute Angle Cloud, is a globally distributed, hardware terminal system that is aggregating all the hardware devices of individuals around the world and is designed based on the edge calculation technology of fog computing to build a web 3.0 interplanetary Internet. Everyone who uses a hardware device that is not saturated and has sufficient computing capabilities to join the Super Network program will become a resource node for the Acute Angle Cloud. With the development of its global nodes, the Acute Angle Cloud will increase its distributed cloud space and its capability to achieve a fully functional distributed cloud computing network system. We believe that through the adoption of blockchain technology, innovation will be able to solve the crisis of trust between people, and create new network relationships, to better integrate community consensus, individual behavior, and value exchange. 1.   Stability Stability is necessary to ensure the existence of the Acute Angle Chain. The blockchain incorporates distributed features for intermediation, and the decommissioning of the network is usually complicated and uncertain. Therefore, we use block design tools to abstract and simplify the blockchain. By building a stack-type smart contract running WebAssembly (WASM) encoding format, we draw two main benefits. Firstly, it optimizes the performance of the virtual machine and directly improves the contract execution efficiency and reduces the interference caused by the system coupling. Secondly, it weakens the correlation between the blockchain network and the smart contract running status - even if the contract execution has problems, or the virtual machine runs abnormally, the block and chain’s network stability can still be guaranteed. 2.   Safety Proof of Work (PoW) has contributed tremendously to the safety of the Bitcoin network. However, due to the increasing difficulty of computing, almost all the rights were concentrated in the miners and mining pools. Through professional cooperation, they have in fact become highly centralized "central servers." If their combination exceeds 51% of the computing power, it can theoretically control most Bitcoin transactions, such as the DDoS (Distributed Denial of Service) attack we are familiar with. In addition, the high power consumption is equally plagued by criticism. The Proof of Stake (PoS) mode is still developing compared to PoW. These developments are mainly based on security and applications. The PoS model has a major advantage in terms of security over the PoW model, but the premise is to attract enough holders to fully get the advantages of that security. Delegated Proof of Stake (DPoS) is an improvement of PoS, and is equivalent to PoS in terms of security. Theoretically, it can improve block response and increase network stability and security. In addition, the Acute Angle Chain innovatively proposes a smart sandbox mechanism. Contracts issued by any person must first be tested in a smart sandbox. The Acute Angle Chain will conduct full-path, automated testing and continuously monitor its operational status. If the health level deteriorates, or if a flaw is found, the network will judge it at its own discretion and avoid problematic contracts that may cause damage to the blockchain ecosystem. 3.   Extensibility Extensibility is put forward to solve the information island problem of incompatible blockchains. Firstly, we believe that upgrading and forking are effective approaches for network evolution, with a  

  main chain and some sub chains taking shape after forking. Technically, main chain and sub chains are completely equivalent, but are arranged with different identifications on the basis of community consensus. Each sub chain may be customized for different commercial applications and Value Exchange Protocol (VEP) is constructed among sub chains, which works similar to a gateway and via which, sub chains can interact exchanging information and value. This can form a blockchain ecosystem of multiple applications. Furthermore, non-blockchain online data is incorporated into the Acute Angle Chain ecosystem, supplemented by smart contracts, to respond to events in the real world. 4.   Usability Acute Angle Chain is a decentralized public blockchain platform. Developers can use the Acute Angle Chain to release Tokens, smart contracts and blockchain systems simply, quickly and safely. The Acute Angle Chain is committed to building a global blockchain network system that allows for the exchange of information, interconnects value and trust. The philosophy and technical mission of the Acute Angle Chain is to build a blockchain world without obstruction.   Working  Principle   Acute Angle Chain connects numerous forks via Value Exchange Protocol (VEP) and even gets through to other networks (maybe non-blockchain) to make data interaction to build a cyberspace of interconnection and multidimensional data correlation. 1.   Contract creation and LVM Smart contract implementation Traditional smart contracts limit the input and output of data on the chain and can only support some simple application scenarios. The Acute Angle Chain, besides allowing for data on the chain, also allows for interaction with data on and off of the chain itself. It further supports the update of data on and off the chain simultaneously. It’s commercial applications in the real world are varied and very complex; this complexity is reflected in the data structure and the logic. A complete Turing programming language and virtual machine are needed to create and execute smart contracts. WASM (WebAssembly) is a portable, underlying bytecode technology whose stack-type virtual machines are custom-designed and optimized for a blockchain environment and can run smart contracts at speeds close to native machine code. The benefits of WASM lie in industry standardization and extensive support. Programmers can develop smart contracts in familiar languages such as C, C++, Golang, and Rust, greatly reducing the cost of learning and improving development efficiency. Therefore, the Acute Angle Chain selects WASM as the execution code of the smart contracts. The life cycle of a contract in a blockchain network can be divided into five stages: 1) Select programming language and create source code; 2)The compiler assembles the source code into WASM bytecodes; 3) The Smart Contract is registered with the Acute Angle Chain; 4) Request the contract to open API; 5)Upgrade or destroy the contract;  

  In the above life cycle, Tokens need to be consumed for registration, request, and upgrade of smart contracts. On the one hand, because the implementation of the contract must consume CPU, memory, hard disk and network bandwidth, the resource providers need to be rewarded. On the other hand, it also uses economics to raise the threshold of network attacks and thus reduce risks. The open APIs of smart contracts are shown to users as RESTful APIs. The contents of HTTP requests are encoded in JSON format. Users can generate and send requests through the browser or mobile phone APP. Acute Angle Chain's RESTful API plug-in receives and recognizes requests from a smart contract’s API, and if it is one, it passes the request to the middleware of the WASM virtual machine. The middleware translates the request content into the byte code of the WASM, then calls the corresponding API of the equivalent contract, and finally returns the result of the API execution to the user. The entire process is shown in Figure 2.1: 2.   Consensus Mechanism Due its distributed nature, the blockchain needs a consensus mechanism that functions properly. Currently, widely used consensus algorithms mainly include: PoW (Proof of Work), PoS (Proof of Stake), PBFT (Practical Byzantine Fault Tolerance) and DPoS (Delegated Proof of Stake). From a safety and practicality standpoint, the Acute Angle Chain uses an improved DPoS consensus  

  mechanism. Result-delegated Proof of Stake (R-DPoS) not only inherits the advantages of DPoS - no need to consume additional resources to distribute rewards – but it can also decide whether to validate the agent’s or the node’s smart contracts according to the network’s transaction status. The Token associated with the Acute Angle Chain can not only be traded for the blockchain basic services such as contract release and network bifurcation, but it also participates in voting and has the opportunity to become a proxy node and provide Token rewards. The Acute Angle Chain named this Token “AAC”. Each AAC holder is called an equity person and is allocated the corresponding voting weight based on the number of AACs held. The agent node is selected by the equity holder. The first 31 winners, agent nodes with the most votes, become deputy nodes, which in turn authenticate the transactions. The work order is determined by the number of votes. The agent node can accumulate rewards if it works normally. If it works abnormally or does not work, it will be punished. The election is conducted in real time and is unending. New users can participate in the voting process at any time, and users who have already voted can also withdraw their votes at any time or change them. Therefore, the elected agent node is not permanent, nor do they have a fixed term, and may be surpassed and replaced by others at any time. In addition, we have made some optimizations in the consensus algorithm to prevent the agent nodes from being fixed and avoid the network from gradually becoming centralized. 3.   Account model In the blockchain network, the account address was designed to provide safety. The address creation follows the following steps: public key, private key as follows: private key—>public key— >account address. All three items use the Secure Hash Algorithm (referred to as SHA), which can ensure safety. Hash is the extraction of information with less output than input and fixed length. The hash with strong encryption is irreversible. i.e., the private key information cannot be deduced by using the account address. The detailed generation process of the private key, public key and account is as follows: The creation of a private key, public key and account can be divided into two kinds of accounts based on the byte length of the account address, main account and sub-account. 4.   Value Exchange Protocol(VEP) VEP refers to standard protocol between different blockchain networks. As mentioned above, the applications that can be loaded on a network are limited, but when different networks connect to form a larger network, this leads to an exponential increase in value. How do single network nodes trust other nodes at first? The biggest advantage of the blockchain network is to provide reliable information, and such reliability is embodied on the distributed account ledger and consensus. A blockchain network is a community that agree on a consensus – this develops a mutual trust relationship between nodes, which is needed for taking a blockchain network as the node and forming connections among several blockchain networks. VEP creates rules for cooperation. It registers the information of each chain and provides services to the chain in letter list for query and connection requests. VEP supports two kinds of application circumstances, cross node interaction and cross chain contract request. The former develops interaction between contracts indirectly by checking the status of data saved on the node or external data and tries to generate new information. For example: unpaid loans due in accordance with the contract will affect the individual credit. A loan record can be saved in the blockchain A, while the credit data can be saved in the blockchain  

  B.  Individual identity information may come from an external public database. While the latter refers to mutual invocation between contracts. A simple case is that the total value is always constant after exchanging the Tokens of the two chains. Acute  Angle  Platform  Application  Scenarios   Scenario - Supply chain finance: Supply chain finance refers to a financial service with the lowest risk that is controlled by information integration under financial institutions (generally refers to banks) managing capital flow and logistics of medium and small sized enterprises. Due to a large number of participants, different kinds of information are saved in each link, which means that commodity information of supplier is stored in the warehouse information of the supplier, shipment information is grasped by the logistics company, capital information is distributed in the bank system, and transfer information is grasped by core enterprise. Because of information asymmetry and non-transparency of information required by collaboration, the effective supply chain credit system is hard to be established. Due to high cost of credit establishment, the financial institution has to operate prudently responding to risk control. Thus, some high quality items are often missed. Acute Angle Platform is able to help enterprises and financial institutions to reconstruct the credit system and establish more efficient supply chain finance. Endorsing the core enterprise, the blockchain platform for warehouse, logistics, digital bill and enterprise credit can be developed through Acute Angle Chain, which can realize commodity, warehouse, logistic and accounts receivable commonly witnessed by the up and down stream enterprises and financial institutions on the supply chain. The issuance, approval, transfer, splitting and acceptance of digital bill shall be triggered by each participant of supply chain through contract, with trigger condition based on change of data status of warehouse, logistic blockchain and core enterprise database, and prepared by the contract of each participant. The behavior of compliance or violation of the rules will be ALL recorded in the credit blockchain, which cannot be tampered. Acute  Angle  Hardware  Series   Overview   The Acute Angle hardware series is one of the components of the New PC Network. It establishes a reward for users through smart contracts based on Content-Addressable Network (CAN) peer-to-peer hypermedia protocol storage, and Acute Angle Chain public chain digital asset management. These include all kinds of hardware devices from personal computers to mobile devices. Using content- addressing technology, the hardware terminal that joins the New PC Network is used as a node to complete the network. CAN connects all computing devices under the same document system. CAN is like a bit stream group that can exchange objects at the same Git warehouse. In other words, CAN provides a content- addressable block storage model and content-addressable hyperlinks, creating a generalized Merkle Directed acyclic graph (DAG). In this data structure, we can establish an edition control system, blockchain, or even a permanent world-wide-web. CAN has combined distributed hash tables, block switching with an incentive mechanism and a self-authenticated name-space. CAN has no single point of failure, and there is no need for mutual trust between nodes.  

  3.1   : Acute Angle PC I generation We named the first product of the Acute Angle hardware series, the Acute Angle PC. We designed both the Acute Angle PC I generation and II generation with triangular shapes in order to reflect the trust, stability, and firmness of the blockchain spirit. The Acute Angle PC I generation is a product based on the blockchain technology. It can use the distributed cloud storage, idle hard disk space, shared cloud computing and bandwidth (contributed by Acute Angle hardware series) to provide comprehensive and sustainable CDN services for Internet businesses. It is also capable of speeding up its service to meet the demand of a large number of innovative businesses such as download platforms, UGC acceleration platforms, online streaming platforms and dynamic acceleration platforms whilst also allocating the ecosystem's reward for those contributions. The customers with the first generation Acute Angle PC are considered founder nodes and get extra rewards. 3.2   : Acute Angle PC II generation The Acute Angle PC II generation is the second PC from the Acute Angle hardware series and an upgrade from the first generation. We have built-in crypto chip technology in the Acute Angle PC II generation, providing users with double encryption to more safely protect their digital assets. It also has a new fingerprint identification and unlocking boot form, more in line with "identity  

  identification”, which is particularly important in the blockchain era. More powerful performance and configuration upgrades will provide users with a better product experience. Hardware  Advantages     1.   Blockchain technology empowers products The Acute Angle hardware series not only retains the hardware’s original features to bring users a familiar but fresh product experience, but also gives them blockchain attributes and distributed architecture, thus applying the blockchain technology to people's daily lives. The "blockchain +" model facilitates people learning and understanding of the technology. 2.   Eco-friendly low-power design The Acute Angle hardware series adopts today's mainstream hardware configuration with even better performance leading to a better user experience. At the same time, however, priority is given to a configuration that has a lower energy consumption, ensuring the user, as a node of the Acute Angle Cloud’s ecosystem can be online all-day long, still taking advantage of safe and stable services, for energy consumption and getting more rewards. 3.   Facilitating equipment maintenance The internal structure and configuration of each Acute Angle hardware series device is highly uniform at the time of shipment to ensure that all products are efficient, safe to operate and accurately respond to user’s needs. Application  Scenarios     1.   Surfing the Internet and entertainment The Acute Angle PC I and II generations use Windows 10 and can be used to perform the same functions of an ordinary PC. 2.   Sharing storage The Acute Angle PC I generation can provide users with a large, safe, reliable and low-cost CDN cloud storage service and provide data reliability. Users can save information on it, access the Internet and connect it to an external hard drive to expand its storage capacity and processing capability; 3.   Reward System Based on the Acute Angle Chain's ecosystem, users can contribute with their own idle broadband, storage and computer capacity to obtain rewards. In the future, the Acute Angle Cloud will open more significant service capabilities and provide users on the cloud with CDN acceleration services that meet the needs of Internet businesses. Not only can users join the New PC Network to share computing resources such as idle CPU, hard disk space, and upstream bandwidth to get ecosystem rewards, but they can also easily gain community rewards through sharing content, gain both intellectual and material fulfillment and sharing the technological  

  innovations’ dividends. Acute   Angle   Coin/AAC   and   Super   Network   Token/   SN   Overview     AAC  and  SN  Introduction     With the development of the Acute Angle Cloud’s ecosystem stability, the applications in the ecosystem will gradually be used. This requires a constant value exchange process to meet users’ needs. The use of the application under the Acute Angle Cloud ecosystem is not affected by fluctuations in the market value of digital assets, so the exchange of applications does not depend on price. Therefore, we will issue the value-based circulation medium Acute Angle Coin (AAC) based on the Acute Angle Chain and the ecosystem’s universal Token known as the Super Network Token (SN). AAC  introduction     In order to ensure the smooth operation of the Acute Angle Cloud Platform and the needs of commercial applications, the Acute Angle Chain main network was based on Ethereum to release the Acute Angle Coin/AAC, with a total volume of 1 billion units. AAC is used as a valuable and exchangeable medium in the Acute Angle Cloud’s ecosystem. AAC will also be used as a digital asset for the Acute Angle Cloud. Users can take advantage of the AAC to exchange for SN and acquire storage space, content review, and application development among other series of interactions the application performs. AAC is based on the sharing economy of cloud computing technology and blockchain technology. Through smart contracts, smart regulations and reporting systems users are ensured that sharing computing resources and content awards them a reward equivalent, which cannot be denied or tampered with; through the decentralization of account records, we ensure that all transactions are true, open and transparent; we use the blockchain to register users' copyrights and modify records thus protecting them from infringement. We designed the first application scenario of the AAC as a universal token exchange method for all application services. It was also created as a medium for users to provide and exchange computer resources and to ensure the user's rights. Early participation is a big advantage due to the increase in difficulty of obtaining awards over time as the limited amount of AAC is distributed as competition grows. In addition, we will provide users with an array of community activities, encouraging more users to join, and deliver more data nodes and bandwidth, storage, computing power, and other resources for the shared computing ecosystem. The entire ecosystem has maintained a good cycle at the Customer end.  

  SN  Introduction     In order to ensure the availability of operational applications and the stability of application prices in the Acute Angle Cloud ecosystem, we will issue a negotiable, equivalent interchangeable ecosystem "universal token" based on the Acute Angle Chain. It is named Super Network Token/SN. The value of each SN token will be anchored to the US dollar to set the price for all applications/functions in the ecosystem. When the user requests the use of a certain function, only a certain amount of AAC needs to be converted into SN (according to the conversion ratio at the time) to be allowed to use the application/function. Throughout the exchange process, point-to-point and end-to-end transaction data security is ensured through the use of encryption technology, distributed ledger technology, trusted cloud technology, and chip technology. AAC  and  SN  application  Scenarios     In the entire Acute Angle Cloud ecosystem, AAC is used to complete the application conversion and SN is used to complete the application activation. AAC acts as a digital asset for users in the ecosystem, and the SN acts as a generic token consumed for activating applications/functions or exchanging resources. The application scenarios of AAC and SN are as follows: AAC  application  scenarios     Cloud storage service The token can be exchanged for cloud storage space based on the users' needs. Shared Cloud computing service The token can be exchanged for safe and stable Cloud computing services, as well as for a large scale of distributed underlying structure and a decentralized and specialist Cloud encryption technology service. Shared CDN service Based on a high quality network infrastructure and Cloud computing technology, low-cost and extensible Internet content distribution services with high performance. As the shared economic of Cloud computing and blockchain technology developers, the AAC will have more application scenarios, including: Shared content services Users can acquire AAC through the Acute Angle PC reward system or by participating in official activities/events, e.g. by advertising different unique content published by other users on the content sharing platform.  

  Open platform for Acute Angle applications Applications developed on the platform can be purchased using AAC. SN  application  scenarios     Acute Angle client SN application activation The first time the user turns on the Super Network application, it requires a certain amount of AAC to be exchanged for SN. Once the exchange is complete, the user can then activate the Super Network application. Acute Angle Cloud Application Exchange After the creation of the Acute Angle Cloud ecosystem platform, the SN can be used in exchange for services and applications on the platform. Trading on the Acute Angle trading platform When the SN reaches a stable stage of development, the Acute Angle trading platform will be launched as a ratio exchange between the designated currency trading pair of the platform and other digital currencies. "Super Network Node" election vote As the number of nodes in the global layout of the Acute Angle Cloud expands and in order to protect fairness and improve the operational efficiency of the network’s decentralization, we will adopt a Super Network proxy voting campaign and use the SN to vote on Super Network Nodes and conduct dynamic elections. Any node can participate in the election, as long as the number of votes can catch up, it will replace the original Super Network proxy. Create a public chain service based on the Acute Angle Chain Users can create a public chain based on the Acute Angle Chain by using SNs, facilitating the threshold to develop, shorten the development time of public chain-linked projects and save on costs. With the establishment and gradual improvement of the Acute Angle Cloud ecosystem, SN will be applied to more scenarios. AAC  and  SN’s  distribution  plan   With the development and maturity of the Acute Angle Cloud, it will gradually support a value service system using AAC as its medium of circulation and SN as its universal token. Both AAC and SN will be used to implement applications including activation, replacement of storage space, content sharing, application development, etc., calculating and recharging exchange functions.  

  AAC  Distribution  plan     When the user participates in an activity initiated on the platform, the smart contract attributed to that activity will automatically generate AAC. Initially, the total amount of AAC will be 1 billion units. The percentage allocated for users’ rewards is 45%, fully protecting users and creating a strong market atmosphere. In order to ensure the prosperity of the Acute Angle community, maintain its healthy development, and invest in the construction of application platforms, the remaining AAC will be retained by the foundation, founding team, and cornerstone investors. The specific distribution of AAC is as follows: Reward System: 45% 45% of the total issuing amount will be given to the users as a reward for using the Acute Angle hardware series reward system. The AAC will be distributed as an incentive to share resources up to a maximum of 450 million AAC. Project Foundation Reserve: 25% 25% of the total issuing amount will be kept by the Foundation as a reserve, which will be used to support the technological development of subsequent projects, community operations, business cooperation, publicity expenses and project maintenance. The Board of Directors will decide the expenditure of the reserve at their own discretion, and make an announcement prior to using this reserve. Cornerstone investors: 25% 25% of the total issuing amount will be given to early private investors in order to kick start the project, build the team, platform operations and other aspects. There will be a lock up period for private sale investors. 50% will be locked when issued, and unlocked when the token is online and available for trading; 25% will be unlocked 3 months after the token starts being traded online, and the remaining 25% will be unlocked 6 months after the token starts being traded online. Initial team and R&D team: 5% 5% of the total issuing amount is given to the initial team and R&D team as a reward. The reward will be unlocked one month after the token starts, opening online at the rate of 0.25% a month for a period of 20 months.  

  5.1: AAC distribution plan 5.2: Plan for releasing of AAC foundation reserve and cornerstone investment AAC  Reward  plan   All the locked AAC will be unlocked step by step according to the schedule. The reward tokens will be unlocked as follows:  

  5.3:AAC Mining Production Plan 2018 - 450,000,000*50% = 225,000,000 AAC 2019 - 225,000,000*50% = 112,500,000 AAC 2020 - 112,500,000*50% = 56,250,000 AAC 2021 - 56,250,000*50% = 28,125,000 AAC ... Note: For calculating AAC release, please see the AAC operating mechanism SN  Distribution  Plan     In order to set the price of the applications in the Acute Angle Cloud ecosystem, the Acute Angle Chain main chain is based on SN, (the Super Network Token) which is issued by Ethereum, and used as the exchange medium for applications (1SN=1 dollar). The SN, as an incentive that runs on the Super Network, will be first issued with 1 billion units. The specific distribution of SN is as follows: Reward System: 45% 45% of initial issuing amount will be given to the users as a reward for using the Super Network reward system. The SN rewards have a limit of 450 million SN. Project Foundation Reserve: 40% 40% of the initial issuing amount will be kept by the Foundation as a reserve, which will be used to support technological development of subsequent projects, community operations, business cooperation, publicity expenses and project maintenance. The Board of Directors needs to decide and make an announcement when using this reserve. Cornerstone investors: 5% 5% of the initial SN issued amount is used to attract early investors. Early investors will contribute to the SN's team building and platform operations. The release will be locked initially and will start unlocking in the 4th month and every subsequent month thereafter. Cornerstone investors will have 10% of the total pool unlocked monthly, and it will be completed in 10 months. Initial team and R&D team: 10% 10% of the initial issuing amount is given to the initial team and R&D team as a reward. The reward will be unlocked one month after the token starts being traded online at the rate of 0.5% of the initial amount a month for 20 months.  

  5.3: Distribution Plan Note: Refer to AAC's operating mechanism for detailed SN generation algorithm Methods  of  acquiring  AAC  and  SN     The AAC is generated through shared Acute Angle hardware resources such as hard drive speed, upstream bandwidth, CPU computing ability and other ecosystem reward mechanisms. It is mutually decided by combining the Acute Angle Chain's interactive behavior in specific block cycles. •   Users can purchase the Acute Angle hardware devices, and activate the Acute Angle Coin's reward plan to get the AAC by sharing resources; •   Users can contribute with upstream bandwidth, available hard drive space, CPU computing power, hard disk speed, and/or a multi-dimensional scoring algorithm according to the equipment stability in order to be rewarded with AAC; •   Users can also participate in Acute Angle Cloud official activities and acquire AAC according to the activity’s rules. •  Acute Angle hardware users in the New PC Network can also receive the Acute Angle Cloud’s ecosystem reward. How  to  get  SN  rewards.     New PC Network devices Users that are part of the New PC Network (including the Acute Angle hardware series and other PCs) can download and install the Acute Angle client, use a certain number of AAC to redeem the activation code and activate the Super Network application. The Acute Angle PC 1st generation is considered to be an Acute Angle Cloud founder node, thus giving the owner the first Super Network activation code free of charge (free activation period is for 31 days, the Acute Angle PC 1st generation will be activated automatically after the client is updated (the  

  user needs to update the client version). It needs to be activated again once the 31 days are over. According to the SN Token Reward algorithm and the AAC Reward algorithm, users are distributed SN and AAC rewards, among which the Acute Angle hardware users will still enjoy the original AAC reward distribution. AAC  and  SN  operating  mechanism     Every user is a transmission node for the peer-to-peer network; AAC is acquired as a reward through sharing idle resources. Each New PC Network device will become a node and an independent server for data collection and transmission. AAC  Rewards  Algorithm   AAC implements multi-dimensional scoring for rewards based on the Acute Angle hardware devices’ processing power, upstream bandwidth, shared hard disk space, etc. The Acute Angle hardware devices’ score represents the contribution in one day, and the AAC generated on the same day is distributed to Acute Angle hardware devices in the entire network according to the score weight. Acute Angle hardware devices score A = (hardware capability × (CPU factor + memory factor) + bandwidth × bandwidth factor + stored value × stored value factor) × (effective online duration × 24 hours × effective online duration factor) × total amount of the day =Ct; Production formula:   × Ct !"#!$#!%#⋯ #!'     Formula analysis •   Hardware capability: CPU efficiency and the Acute Angle devices’ memory. Currently, the Acute Angle PC has a consistent hardware ability, with an ability value of 1, CPU factor weight of 20, and memory factor weight of 10; •   Bandwidth: Upstream bandwidth (measured in trusted nodes). To encourage the participation of distributed nodes, the decay factor of bandwidth factor is 10 at 1-8M, 5 at 9-20M, and 1 at 21-100M; if the bandwidth is above 100M, it is calculated as 100M using a progressive algorithm (see below for details); •   Storage: The storage space available for sharing is measured from the trusted node. In order to encourage users to share their idle storage resources, the storage value is 0 when the storage space is less than 200G, the storage value is 1 when the storage space is 200G-1000G, and the storage value is 2 when the storage space is greater than 1000G. The storage factor is 5; •   Read and write:  

  The read-and-write is 1 when the read-and-write speed is 1MB / S-99MB / S; The read-and-write is 2 when the read-and-write speed is 100MB/S-200MB/s; The read-and-write is 3 when the read-and-write speed is above 200MB/s. The read-and-write factor is 10; •   Effective duration factor: The effective time factor is 1, the effective online duration is 24 hours for 7 consecutive days, the effective time factor is 1.1, during which, the effective time is interrupted. Then the effective time factor will be recalculated from 1. •   Online duration: The trusted node aggregates the effective online duration of the previous days every day, calculates the score of the entire network, and distributes the AAC. Acute Angle hardware devices’ Score Algorithm Example: 1.  When the upstream bandwidth is 1M, the storage space is 100G, the read-and-write speed of hard disk is 20MB / s, and the PC is online 12 hours; PC Score= [1*(20+10) +1*10+0*5+1*10] *(12/24*1) =25 2.  When the upstream bandwidth is 10M, storage space is 500G, the read-and-write speed of the hard disk is 50MB / s, and the PC is online 24 hours; PC Score= [1*(20+10) + [8*10+(10-8) *5] +1*5+1*10] *(24/24*1) =135 3.  When the upstream bandwidth is 100M, storage space is 1500G, the read-and-write speed of the hard disk is 100MB / s, and the PC is online 24 hours; PC Score= [1*(20+10) + [8*10+(20-8) *5+(100-20) *1] +2*5+2*10] *(24/24*1) =280 4.  When the upstream bandwidth is 100M, storage capacity is 1500G, the read-and write-speed of hard disk is 100MB / s, the PC is online 24 hours; the total duration is 7 * 24 hours; PC Score=[1*(20+10)+[8*10+(20-8)*5+(100-20)*1]+2*5+2*10]*(24/24*1.1)=308 The coin decay algorithm 1)  Decay period y: The period for each yield reduction y = 1 year (365 days) 2)  Decay factor d: The proportion of each reduction adopts the halving method, d = 50% 3)  The initial amount of coins C: The number of coins rewarded per online time is calculated based on the total amount and the C=620k/day. The yield of coins is halved every 365 days, meaning the total number of tokens generated from rewards indefinitely approximates 450 million.  

  SN  Rewards  Algorithm     SN is based on the hardware capabilities of the New PC Network equipment, bandwidth, sharable storage size, etc. to conduct multi-dimensional scoring incentives. The New PC Network equipment score is relative to its daily contribution, according to the score weight of the New PC Network entire network’s hardware distribution on the day that the token is generated. New PC Network device score P = (hardware capability × (CPU factor + memory factor) + bandwidth × bandwidth factor + stored value × stored value factor) × (effective online duration÷10   hours× effective online duration factor) × day’s total currency amount = Ct; Production formula: ("   × Ct ("#($#(%#⋯ #('     Formula analysis: •   Hardware capability: The CPU efficiency and memory size of the New PC Network hardware. When the CPU's main frequency is 1-3G, the factor weight is 20; when the CPU's main frequency is 3.1-4G, the factor weight is 30; when the CPU's main frequency reaches 4.1 or higher, the factor weight is 40; Equal to (threads/cores) *(cores/4). The memory weight is memory/4*10; •   Bandwidth The measured upstream bandwidth of the trusted node. In order to encourage the participation of distributed nodes, the bandwidth factor is 10 at 1-8M, 5 at 9-20M, 1 at 21-100M, and at 100M or more it is calculated as 100M using a progressive algorithm. •   Storage Measured by the trusted node. The storage space can be used to obtain rewards, and encourages users to share more of their own idle storage resources. The storage value is set to 0 when it is less than 200G, 1 when it is 200G-1000G, and 2 when it is greater than 1000G. The storage factor is 5; •   Read and write: The read-and-write is 1 when the read-and-write speed is 1MB / S-99MB / S; The read-and-write is 2 when the read-and-write speed is 100MB/S-200MB/s; The read-and-write is 3 when the read-and-write speed is above 200MB/s. The read-and-write factor is 10; •   Effective duration factor:  

  The effective time factor is 1, the effective online duration is 24 hours for 7 consecutive days, the effective time factor is 1.1, during which, the effective time is interrupted. Then the effective time factor will be re-calculated from 1. •   Online duration: The trusted node aggregates the effective online duration of the previous days every day, calculates the score of the entire network, and distributes the SN. The coin decay algorithm 1)  Decay period y: The period for each yield reduction y = 4 years (1424 days) 2)  Decay factor d: The proportion of each reduction adopts the halving method, d = 50% 3)  The initial amount of coins C: The number of coins rewarded per online time is calculated based on the total amount and the C=ß16w/day. The yield of coins is halved every 4 years, meaning the total number of tokens generated from rewards indefinitely approximates 450 million.
