Casper API

About

Casper API is a decentralized data storage system for DApps (decentralized applications) on any blockchain with smart-contracts. Casper API is a cross-chain solution allows creating new DApps never before possible. For example: decentralized blogging platforms (like Medium), marketplace or social media. Casper API raises the level of the blockchain ecosystem, thereby developing the blockchain market. The technologies by which the Casper API complements any blockchain with smart-contracts are decentralized p2p storage and CDN.

Imagine our nearest future, when information will not only be generated by you, but billions of IT devices: drones, self-driving cars, robots, AR/VR. All of them require an immense storage volume for information, which will cause significant demand for the service in question from both classic-style applications and DApp.

Casper API can help solve the issue of high data storage prices. After switching to a decentralized storage you can save up to 66% compared to the cloud storage giants of today. This is made possible with the help of providers putting up their hard drive capacity, both private persons and data centers can put up as little as 25.6 GB for rent and enjoy monthly rewards in CST – the system's tokens. It will help increase the reliability and security of the data stored due to decentralization. You will never lose your data and will always have access to it. By uploading your data you can be sure that you alone is the only person with the access.

Located all around the world, providers ensure the operation and security of the entire network, and the smart-contract automatically runs hourly check-ups when copies are created. Thus upon finding a disconnected provider, the system immediately copies all the data stored on his HDD, keeping the number of proper copies.

Cloud storage market looks like the most perspective out there at the moment, projected to reach $72 billion by 2020. This makes the solution put forth by Casper API all the more attractive.

FAQ

What is DApp?

DApp (Engl.) Decentralized Application. As an ordinary application, Dapp consists of the user interface (frontend) and the server part (backend), but is different from it as it includes a smart contract. The smart contract is also a part of the backend, only it is created especially for the block-chain. In essence, the smart contract is a contract between the developers and the users that provides for full transparency of application performance. Decentralized applications include games, social networks, postal services and all other things that we are so used to in the world of the Internet. The only difference is that their operation is fully transparent.

What is a Smart Contract?

In concept, this is a contract, a computer algorithm having conditions preset and open for any participant, and when these conditions are fulfilled, the parties will be able to exchange money, assets, or new processes will be launched free from participation of third parties (agents).

What is Casper API?

Casper API is the infrastructural element that allows any DApp to set up a decentralized cloud storage of service data using any block-chain with a smart contract.

How does this work?

The decentralized application requests from smart-contract a free space to place content, smart-contract sends an address of the server where data may be uploaded. The Casper API system, during the upload, copies the file to 3 more servers, in summary, we have 4 copies of the file. Further, this number of replicas is maintained. When one server is no longer available in the network, it will be replaced by a new one, which downloads a copy from the 3 remaining servers. Depending on the content, the application developers may encrypt or not encrypt the data. Casper API stores 4 copies of files encrypted or open for review.

Who are providers?

The providers are individuals or legal entities that offer a certain volume of storage space on their computers/servers using Casper API and receiving remuneration for these services using Casper tokens (CSTs).

How is it different from the competition?

No one on the market has already made or even declared the creation of storage infrastructure for decentralized applications. We are creating a decentralized storage under smart contract management. DApp will be able to interact with the storage by referring to the smart contract. This eliminates the risks of architecture limitations in other systems. We are ready to work with every platform that uses a smart contract. As of today, these platforms include Ethereum, Graphen and Neo. As new block-chains appear, we will be able to start working with them immediately.

When did the PRE-ICO take place?

The PRE-ICO started on December 19, at 2 pm MSK. It was completed in one hour and raised 1239 ETH, which at the time amounted to slightly over $1,000,000.

When will ICO take place?

We will be able to provide more accurate information on the terms of ICO a bit later; as of today, plans are to hold it on 30 May 2018.

How can I become a provider in your system?

Our system has several requirements for those who wish to become our providers. First, you will need high-speed Internet access, free disk space and Casper tokens (to provide 25,6 GB you will need 1 CST). Secondly, our system regularly checks on providers, so you must be online 95% of the time.

What is the payback period for the provider?

You can use the convenient calculator on our website to calculate the approximate pay-off period depending on your country of residence, and the prices for electricity, the Internet connection and the equipment.

Where can I find more information about you?

We are available in: Telegram, Medium, Twitter, GitHub, Bitcointalk, Facebook, Steemit, Reddit. Also, on YouTube we maintain a blog about new generation of blockchain, business and bitcoin - Generation B.

Who will be the clients of the Casper API?

Dapp developers will be the first clients of the Casper API platform.

What is an ICO?

The ICO or Initial Coin Offering is when some project issues coupons, or tokens intended to pay for services the site renders in the future.

Is there a limit to the size of the file stored in the system?

No. No limits to the file size.
