Fast, profitable, protected storage of video, audio, documents, photos on any blockchain.

Detailed description

Casper is being created for your DApp to store information from your users more efficiently and reliably. We want DApps to develop fast - independently from the blockchain platform. To simplify the problem of selecting their own DApp, we don’t burden developers with data-storage issues for their clients. This has been made possible with our Casper API. Any DApp on any blockchain platform with a smart-contract can use our API to store any type of data.


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.


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 API allows us to make use of all the capabilities already present in cloud storage, such as data storage and content distribution network (CDN). The infrastructure can be used for all kinds of applications, websites and even offline businesses with no use of smart contracts. Combined with the architecture capabilities such as automated content delivery through smart contracts on blockchains as well as SDK for DApps make Casper API an attractive solution for the budding market of decentralized applications.


  • High-speed access to decentralized file storage 
  • Security on a corporate level: confidential transactions through a private channel using a cryptographic protocol similar to the Lightning Network 
  • Data protection: each file is stored by 4 independent storage capacity providers 
  • Cost reduction: data storage and distribution for end users costs 3 times lower than traditional CDN and cloud storage solutions
