The goal of Polar Chain is to use blockchain technology to make a more efficient, more stable, more scientific and reasonable edge computing platform. Comply with the original purpose of "everyone is equal" in the blockchain, and realize the proof of contributing effective resources, that is, Proof Of Useful Work (POUW). Polar Chain collects idle resources such as bandwidth, computing, and storage, making everyone an edge computing node, and each edge node can process and execute nearby businesses and earn benefits. We rely on countless nodes to form a decentralized peer-to-peer edge computing platform, which eventually becomes a super edge cloud - Polar Chain.
Polar Chain is committed to building a complete ecosystem within the decentralized peer-to-peer edge platform, reconstructing the existing Internet model, realizing value circulation and upgrading, and completing the "last mile" of Web 3.0.

Business scenarios of Polar Chain

1. Video Acceleration
The intelligent video acceleration service mainly improves the quality of experience (QoE) of users by shortening the start time of content and reducing the stop time of video, and ensures the Maximum utilization.

2. Internet of Things
As the next "important productivity" that promotes the rapid development of the world, the Internet of Things has developed rapidly in recent years. The concept of "Internet of Things" is a network concept based on the concept of "Internet", which extends and expands its client terminal to any item and item for information exchange and communication. The Internet of Things refers to a huge network formed by the combination of various information sensing devices, real-time collection of any required information such as objects or processes that need to be monitored, connected, and interacted, and the Internet. Polar Chain makes it easier to integrate and normalize data. The I/O interface on the smart device can easily connect traditional industrial systems and the Polar Chain network. Gateways can connect and communicate with endpoints using Wi-Fi, WWAN, and Ethernet. In addition, the processing power of the gateway supports the intermediate equipment to aggregate, convert and standardize the data from all the different protocols (from ModBus, BACnet to Zigbee, etc.), and then transmit the data to the core network through the gateway. Polar Chain can perform edge analysis on connected terminals, transfer decision-making to the edge, provide real-time operations, and can also help manage network problems, solving network bandwidth problems by deciding whether to move data to the edge.

3. CDN
With the rapid development of mobile Internet technology, mobile network data traffic presents an explosive growth trend. According to the 2017 Cisco VNI report, by 2021, global mobile data traffic will reach 49EB per month, and mobile video traffic will account for 78% of global mobile data traffic. Content providers upload tens of thousands of video contents every day, such contents are stored in a large amount in the provider's centralized database, then converted from the source format to the final delivery format, and distributed to multiple streaming servers located in different locations on the network , and pass on further. Despite the content distribution efforts, the distance from the content to the user is still long, especially in a mobile environment, where individual users may experience service interruptions due to buffering issues and jitter. Therefore, Polar Chain provides distributed caching by extending the CDN service to the mobile edge, which can enhance the user's QoE and reduce the use of backhaul network and core network.

Polar Token Usage Scenario

Payment Features
Polar Token is the payment method for Polar Chain's own services. Since Polar Chain has the dominance and pricing power over the services provided independently, the secondary market price of Polar Token will not affect the services that Polar Token can be exchanged on Polar Chain, or the utility. At present, the services that Polar Chain can provide include but are not limited to:
(1) Edge computing services that B-end users can obtain through Polar Chain edge cloud;
(2) All mining that mining customers participate in through Polar Chain project.
Admission ticket function
Polar Token is the certificate of the mining platform. For example, some mining projects require Polar to open the function.
Dividend function
Polar platform business income will be used to regularly repurchase Polar Token and burn it, thereby reducing the secondary market circulation.
Credit pledge function
The Polar mortgage logic runs through the entire mining cycle. In order to make the Polar Chain network more stable in providing services (such as CDN business), we have designed Mortgage logic for the shortest period. Miners need Polar Token as collateral for mining.
Community self-government function
Miners and other community members can use the amount and period of Polar Token they hold as qualifications to participate in various autonomous groups in the community. At the same time, Polar Token can be used within the scope of community autonomy as
tools such as voting, likes, and community rewards.
The super nodes in the node plan, in addition to providing hardware resources, will also play a role in community autonomy, including publicity, management and other aspects. The foundation will use Polar Token to reward supernodes that contribute to the ecology.
