Casper API - The Infrastructure of Decentralized Cloud-based Bata Storage for DApps with an Universal API

What is Casper API?

Casper API is an infrastructure project designed for decentralized data storage compatible with any blockchain platform with smart contract capabilities.

Casper API creates an infrastructure to store data on any Blockchain platform with smart contract capabilities. You can store documents, photo, video, 3D model and audio files.

We are developing a universal solution that can work with any blockchain. Emerging markets see players come and go. Integration with multiple platforms mitigates the risk of error in choosing any single partner, making our economic model more stable, which in turn allows for storing data with providers from different sources.

According to Gartner research, cloud storage market will have reached 72 billion dollars by 2020. In their research, Gartner did not discern the traditional centralized storage market from the decentralized applications market.

We clearly see the new opportunity to satisfy the market demand. In 2017 alone 1092 DApps (decentralized blockchain applications) were created and this trend is becoming even more widespread in 2018.

The existing blockchain-based data storage solutions are extremely expensive and cumbersome. Traditional ones are not fit for the new, decentralized market segment. DApps are facing the need to organize decentralized data storage in a profitable, secure and innovative way. To accomplish that DApps need a decentralized infrastructure.

In the near future information will be generated by people as well as billions of IoT and AR/VR devices, drones, self-driving vehicles and robots. All that will require vast storage volumes, forming a substantial demand for this service from both traditional applications and DApps.

Casper API is attractive to traditional businesses since it allows to reduce data storage expenses three-fold compared to centralized solutions. Decentralized structure proves valuable to DApps as it provides full transaction transparency, simple integration via SDK and both secure and cost-efficient storage

Platform overview

• Smart contract - The Casper API smart contract stores a service providers register, connects providers with users and performs billing procedures. The smart contract regulates the storage network and supervises the work of providers.
• P2P architecture
  Reliability. All the network participants connect with each other with relying on large nodes such as servers allowing for an increased resistance to DDoS attacks.
  Content delivery. P2P network participants have no geographical limits. Therefore, users are able to receive their data from the nearest provider in order to have their upload and download speed increase.
  Data accessibility. Several copies of one file are stored by different providers allows to download data even if one of the providers is down.
• ZK-SNARK - To ensure strict confidentiality the data on all the operations is transferred to the smart contract in a secure and encrypted way. We use the zk-SNARK encrypting method, also used in ZCash. This makes Casper API suitable for use in corporate level DApps.
• SDK - Casper API provides SDK for integration, allowing application developers to access their data within the Casper API infrastructure.

CST Value Projection and CST Holder Privileges

As it was said before, Casper API plans to list CST on the biggest crypto exchanges so CST/USD exchange rate can be established in live trading where the supply and demand market forces are at play. However, in the long-term the main CST growth driver will be the volume of data within the system - the number of Tb the users will purchase through Casper API.

Below you can find our understanding of the logic behind establishing a fair CST exchange rate that comes from the fundamental factors, such as CST distribution among market participants, overall data volume and the quota size for providers per 1 CST (hereafter - CST capacity).

Marketing Plan

Anyone planning to create a DApp knows what opportunities the blockchain technology has to offer. We want to help our users concentrate their efforts on the main advantages of their DApps and not bother with their own data storage infrastructure development, which can be easily replaced with the Casper API services. We offer secure decentralized data storage infrastructure for your DApps. Our storage fees will lower every year, cutting your expenses and increasing your DApps market competitiveness.

Our main marketing objective is not only to let developers know about Casper API infrastructure capabilities, but also to persuade regular users that using Casper API for DApps is the new way of data storage that guarantees their data security and confidentiality.

To make our marketing plan clear to everyone we decided to organize it into separate blocks. They show how we are going to promote Casper API, cover our progress, find new team members and manage our community. This is how we try to make our marketing spending of the funds raised during the PRE-ICO and ICO more transparent. 

We pay close attention to community management. We will do everything we can to make our replies prompt, detailed and clear, and we will take your replies into account and make the necessary changes

Financial Model

• Main provisions and assumptions of the Casper API financial model:
• Operating expenses are covered with Casper API profit and fixed capital;
• Company profit is comprised of users (DApps) payments for data storage minus the money allocated for the providers reward fund and the sales revenue from CST acquired from commission fees on CST turnover within the  system (token lease).
• The fixed capital of the company is comprised of the cryptocurrency assets raised during the ICO 31
• Main expenses:

1. Project team budget (salaries) and associated costs (office and equipment rent, taxes);
2. Project team reward - 18% of raised funds;
3. Marketing costs - attracting new users;
4. Company reserve capacities costs (hosting fees);
5. Listing on exchanges;
6. Money allocation for the reserve fund;

• The main factors affecting the financial state of the company are:

1. The number of users (DApps) and their demand for the service;
2. New users attraction cost;
3. The number of providers joining in (storage volumes available for use).

Casper API services

• Data storage - The main service we provide is decentralized data storage, including upload, download, editing, deleting, access permission management, file random read function, unencrypted data modification without replacing it as well as the possibility to mount your virtual storage as an external drive. The decentralized data storage system reduces possible delays and increases accessibility which means that all the data is accessible 24/7.
• Backup copy storage - We offer a special backup data storage plans that allow for cheaper service if you access your data rarely. In order to ensure a higher level of safekeeping for your backups we offer to store another copy of your files in partner data centres and other major providers who are ready to take on the responsibility for the security of your data.
• CDN - Your website load time is fast within a target region. Thanks to the decentralized architecture, Casper API is able to provide fast file downloading and website loading as well as increase the stability of your website even under high loads. Thanks to Casper API you are able to choose between provider networks in your target regions.

Casper API does not depend on any blockchain and allows receiving data from different blockchain platforms at the same time. Due to this fact it is compatible with any application on any platform. Providers have the opportunity to increase their profits, while application developers enjoy easy integration with different platforms.

Casper  Token (CST)

CST owners have the following opportunities

• Become a provider of resources (1CST = up to 25.6Gb) in order to provide the data-storage needs of the service, and receive rewards for it.
• To lease out the token to the supplier and receive part of its rewards for using your token.
• To sell the token freely on the stock exchange at market value.
