Filechain & Filehub
Upload NFT images and metadata, add redundancy for critical content, or store anything on-chain.
Use case · Data
The blockchain built for data.
Chromia changes the structure of blockchain state. Relational tables at consensus, not key-value mappings — with native indexing, SQL-like queries, and on-chain file storage.
01·Decentralized data as a service
Why this matters.
Decentralized relational DB
Most Web3 projects rely on centralized databases for relational data. Chromia eliminates that dependency.
Application data layers
Public records, order books, AI memory, vector embeddings — anything that wants structured queries.
02·Innovation
Chromia innovates.
Unlike traditional blockchains that store key-value mappings, Chromia uses relational tables. The architecture boosts efficiency and unlocks complex use cases.
- →Natively query on-chain data — filter, sort, project, join.
- →Perform thousands of read/write operations in a single transaction.
- →Block data is automatically indexed — no third-party indexers required.
03·Case study
VfB Stuttgart.
Digital Collectibles Marketplace
Launched in November 2023, VfB Stuttgart’s marketplace uses Filechain and Filehub to store images and metadata directly on Chromia. This proof of concept showcases what NFT collections from any chain can use to remove their reliance on centralized infrastructure.
