Technical Highlights

Last updated 8 months ago

Was this helpful?

DeOSS not only has the advantages of existing market products on object storage (such as high reliability, easy extensibility, low cost, high security, etc.), but also possesses the features such as anti-censorship, data ownership belonging to its user, and so on. Currently, the object storage services of web2, such as the OSS (Operation Support Systems) of AWS and Alibaba Cloud, are centralized storage. That means their service sacrifice user’s data to be in the custody of a third party, and there is a risk of data being regulated and monopolized. By contrast, based on CESS blockchain technology, the data uploaded through DeOSS enjoys decentralized storage, and the data ownership is secured to the user. Through DeOSS, users can authorize certain applications to use the data, while keeping these applications from controlling the data.

Location-based Storage Selection (LBSS)

DeOSS supports flexible selection of the geographical location and storage scope of data storage according to the needs of different countries or customers, and effectively ensures the compliance and security of data. Even in the scenario of cross-border data storage, LBSS can ensure that data will not be leaked to unallowed territory or areas.

As shown in the figure above, by selecting a range, region or storage nodes on the map, the data will be stored on the specified nodes in the red area.

Data Privacy Management and Permission Layering

DeOSS allows data access through key authentication, offers permission classification and privacy management functions, and provides flexible and unrestricted privacy controls for both enterprises and individual users.

Massive Data Storage

DeOSS, is an HTTP API-based tool for storing and retrieving unstructured data and metadata objects, caters to high-frequency dynamic data storage requirements and enterprise-level large-scale storage needs.

Millisecond Data Retrieval

DeOSS has enterprise-level high-performance data access capabilities, supporting users to access the desired data at millisecond-level speeds anywhere in the world, allowing users and DAPPs to enjoy decentralized data storage services with efficiency comparable to traditional centralized storage.

Censorship Resistance

DeOSS ensures that data is not easily censored, blocked, or deleted during transmission and storage through various technical means, and ensures that users can access and share data in a restricted or interfered environment.

Hybrid Encryption

DeOSS uses Symmetric Encryption, Asymmetric Encryption, Proxy Re-Encryption, and Attribute-Based Encryption (ABE). In particular, DeOSS also has the capability of Fully Homomorphic Encryption, FHE. DeOSS protects the security and privacy of data through various encryption algorithms, and supports hybrid encryption technology that combines multiple encryption methods to achieve a balance between privacy protection and efficiency, to meet the needs of diversified data encryption.

Highly Scalable and Customizable

Built with modular, pluggable components, DeOSS can easily scale and customize according to demand, supporting elastic scaling, intelligent load balancing, and multi-dimensional expansion.

Diversified Interface

DeOSS supports a variety of practical functions such as Chunked Upload/Download, Resumeable Upload/Download , Batch Upload/Download, Data Compression Storage, and fully provides service interfaces . DeOSS will continue to integrate developer-friendly functional modules and strive to become a fertile land for various application development.
