In blockchain storing and using large files like documents images or videos is a major challenge Traditional blockchains are inefficient and expensive for this purpose often forcing applications to store critical data on separate centralized servers This creates security risks and breaks the decentralized model Vanar Chain addresses this core issue with a technology called UDF(Universal Data Format)storage developed within its Neutron layer
The Challenge of Data on Blockchain
Most blockchains are designed to record simple transactions not large amounts of complex data Storing a multi-page legal contract or a high-resolution image directly on-chain is typically impractical due to high costs and technical limitations. As a result, many so-called decentralized applications (dApps) actually store their essential data on traditional cloud servers linking to it from the blockchain. This creates a point of failure as the data's availability and integrity depend on that external server remaining online and unchanged.
How UDF Storage Compresses and Preserves Data
Vanar's solution is the UDF or Universal Data Format The Neutron layer uses artificial intelligence to process a complete file—whether it's a PDF an image or a video—and compresses it into a tiny digital "seed." This seed which is only a few bytes in size is what gets permanently stored on the blockchain Crucially this seed is not a simple hash or summary it is a structured information-rich representation Because it is stored directly on the immutable Vanar Chain the data gains the blockchain's inherent security and permanence eliminating reliance on external servers.
Unlocking Data for On-Chain Applications
The true innovation lies in how this stored data is used The compressed UDF seed can be retrieved and interpreted by the Kayon layer another component of Vanar's architecture. Kayon acts as an on-chain reasoning engine reconstructing and understanding the information within the seed This allows smart contracts to actively interact with the data. For example a smart contract could automatically validate the terms within a stored legal agreement verify the authenticity of a certificate or check the details of an invoice before releasing a payment This transforms static stored files into active queryable components of decentralized applications.
In summary Vanar's UDF storage solves a foundational blockchain problem by making it feasible and efficient to store complex data directly on-chain. By moving critical data away from centralized servers and into a secure structured format that smart contracts can understand it enables a new generation of more capable truly decentralized applications for finance, legal processes and digital asset management.
